A roof that chalks white under the sun, a fa\u00e7ade that fades to a patchy, uneven tone, a wall panel that cracks along the bend after a cold winter: these are the classic symptoms of a coating chosen for price instead of environment. If you are weighing <strong>PE vs SMP vs HDP vs PVDF<\/strong>, you are already asking the right question. The difference between these four resin systems decides whether your building still looks new at year three or at year twenty-three \u2014 and whether you re-coat on your own budget or on your client&#8217;s patience.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide is written for international buyers, distributors, architects and contractors who procure prepainted coils and sheets from Chinese mills and need a neutral, fact-based way to match coating chemistry to real site conditions. We are supplier-neutral: the most expensive resin is not always the right answer, and the cheapest is rarely the safe one. One thing worth saying up front: the re-coat bill almost never lands on the supplier&#8217;s desk \u2014 it lands on yours.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-c0a117dd\"><h2 class=\"uagb-heading-text\">Key Takeaways<\/h2><\/div>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Coating is the single biggest driver of appearance life.<\/strong> PE lasts 7\u201310 years, SMP 10\u201315, HDP 15\u201320, and PVDF 20\u201325+ years in realistic service.<\/li>\n\n\n\n<li><strong>Flexibility runs opposite to durability.<\/strong> PE bends best (T1\u2013T2); PVDF bends worst (T4\u2013T5) and can crack on deep-formed parts.<\/li>\n\n\n\n<li><strong>PVDF has a trap.<\/strong> Genuine PVDF resin content should be \u226570% (70\/30 resin\/ceramic).

When that film loses gloss, chalks, or cracks, corrosion begins at the cut edge and the panel&#8217;s structural protection is compromised long before the steel itself fails.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The four dominant resin families in the global PPGI\/PPGL market are polyester (PE), silicone-modified polyester (SMP), high-durable polyester (HDP), and polyvinylidene fluoride (PVDF). They sit on a clear ladder of durability and price. The table below is the single most useful reference you will use when scoping a project.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a moderate climate, typical exterior service life ranks as follows: <strong>PE 7\u201310 years, SMP 10\u201315, HDP 15\u201320, and PVDF 20\u201325+ years<\/strong> \u2014 durability climbs as flexibility falls.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Coating<\/th><th>Typical service life (exterior, moderate climate)<\/th><th>AAMA grade<\/th><\/tr><\/thead><tbody><tr><td><strong>PE<\/strong> (Polyester)<\/td><td>7\u201310 years<\/td><td>2604 (typical)<\/td><\/tr><tr><td><strong>SMP<\/strong> (Silicone Modified Polyester)<\/td><td>10\u201315 years<\/td><td>2604<\/td><\/tr><tr><td><strong>HDP<\/strong> (High Durable Polyester)<\/td><td>15\u201320 years<\/td><td>2604<\/td><\/tr><tr><td><strong>PVDF<\/strong> (Polyvinylidene Fluoride)<\/td><td>20\u201325+ years<\/td><td>2605<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">FOB China, 0.5 mm \/ Z100-equivalent baseline.

Understanding the Color Coated Steel Structure<\/h2><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Before comparing resins, understand what you are actually buying. Quick decode: <strong>GI = galvanized (zinc-only coating); GL \/ Galvalume = aluminium-zinc alloy (far better at the cut edge).<\/strong> A coil of color coated steel is a five-layer laminate, each layer with a job:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Sustrato<\/strong> \u2014 galvanized (GI) or galvalume (GL\/Galvalume) steel strip. This is the corrosion backbone.<\/li>\n\n\n\n<li><strong>Chemical pretreatment<\/strong> \u2014 chromate-free conversion coating that bonds paint to metal and slows under-film creep.<\/li>\n\n\n\n<li><strong>Primer<\/strong> \u2014 the adhesion and corrosion-inhibition layer between pretreatment and top coat.<\/li>\n\n\n\n<li><strong>Top coat (finish)<\/strong> \u2014 the decorative, UV-resistant film (PE, SMP, HDP or PVDF). This is what buyers argue about.<\/li>\n\n\n\n<li><strong>Back coat<\/strong> \u2014 the reverse-side film, often a thinner epoxy or polyester, protecting the unseen face.<\/li>\n<\/ol>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-f1bd9a21b921d6f3a525d4b9f6ba0b52 wp-block-paragraph\">The substrate choice interacts with the coating choice. <strong>GI (galvanized)<\/strong> suits ordinary inland work: a zinc layer sacrifices itself to protect the steel. <strong>GL \/ Galvalume (AZ50\u2013AZ150)<\/strong> replaces most zinc with an aluminium-zinc alloy, giving markedly better cut-edge and atmospheric corrosion resistance \u2014 essential near coasts and in industry. Our <a href=\"https:\/\/wanzhisteels.com\/es\/galvanized-steel-guide-analysis-of-key-issue\/\" target=\"_blank\" rel=\"noopener\" title=\"\">galvanized steel substrate (GI) guide<\/a> explains the metallurgy, and the <a href=\"https:\/\/wanzhisteels.com\/es\/gi-gl\/\" target=\"_blank\" rel=\"noopener\" title=\"\">GI and GL steel coil substrate<\/a> comparison covers when to step up to galvalume.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A useful mental model: <strong>coating protects appearance; substrate protects structure.<\/strong> A PVDF top coat over weak GI still fails at the edge in a salt-spray climate. The right answer is almost always coating <em>y<\/em> substrate specified together.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-9148dc46\"><h2 class=\"uagb-heading-text\">3. PE (Polyester) Coating: The Cost-Effective Standard<\/h2><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Polyester is the workhorse of the color coated steel world \u2014 the default resin on the majority of architectural and general-purpose coils. Its chemistry gives it the <strong>best flexibility of the four families<\/strong>: typical T-bend performance of <strong>T1\u2013T2<\/strong>, meaning it survives tight bends, deep drawing and roll-forming with minimal risk of micro-cracking.<\/p>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-ad5a28e2c1d383a4623a521b2a59bece wp-block-paragraph\">That flexibility is exactly why PE dominates applications with complex shaping: sandwich panels, <a href=\"https:\/\/wanzhisteels.com\/es\/ppgi-corrugated-sheet\/\" target=\"_blank\" rel=\"noopener\" title=\"\">deep corrugated profiles<\/a>, appliance bodies and interior partitions. PE also takes color and gloss well and is the cheapest resin per ton.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The trade-off is durability. Under sustained UV, standard PE loses gloss and <strong>chalks<\/strong> \u2014 a permanent, powdery white bloom on the surface (the resin has literally broken down; it cannot be washed off) \u2014 within roughly 7\u201310 years in exterior service, and color shifts noticeably. It is the wrong choice for a sun-exposed roof in a high-UV region, but it is the <em>right<\/em> choice for a budget-limited project that must be formed into tight shapes. We will say it plainly: if your job is &#8220;limited budget + needs forming,&#8221; <strong>PE is the correct answer<\/strong>, not a compromise you should apologize for.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-3da2bdbc\"><h2 class=\"uagb-heading-text\">4. SMP (Silicone Modified Polyester): Hardness and Heat Resistance<\/h2><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">SMP modifies polyester with silicone (typically 10\u201330% silicone content) to lift two properties PE lacks: <strong>surface hardness and heat resistance<\/strong>. The result resists abrasion, scuffing and thermal aging better than straight PE, which is useful for touch-prone surfaces and moderately hot environments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cost is flexibility. SMP typically performs at <strong>T3\u2013T4<\/strong> on the T-bend scale \u2014 a noticeable step down from PE. Over-bend it and you invite hairline cracks at the forming line. sap&#8217;s service life lands at <strong>10\u201315 years<\/strong>, sitting just above PE and below HDP, while its price band ($845\u2013960\/ton) actually sits <em>above<\/em> HDP in many Chinese mills&#8217; books because silicone resin is costly. For that reason SMP is increasingly a niche choice \u2014 specified when hardness\/heat matter more than bendability, and less often when the buyer simply wants &#8220;more life for the money&#8221; (where HDP wins).<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-eb963d02\"><h2 class=\"uagb-heading-text\">5. HDP (High Durable Polyester): The Value Sweet Spot<\/h2><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">HDP is the resin most often recommended by experienced mills when a buyer says &#8220;I want PVDF-like life without PVDF price.&#8221; By tuning polyester chemistry and pigment loading, HDP reaches roughly <strong>60\u201380% of PVDF&#8217;s weathering performance<\/strong> while costing about the same as \u2014 or a little more than \u2014 standard PE.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Realistic exterior life is <strong>15\u201320 years<\/strong>, with far better gloss and color retention than PE under sun. Flexibility stays respectable at <strong>T2\u2013T3<\/strong>, so it handles most roll-forming and moderate profiling without cracking. At $775\u2013875\/ton it is the best value in the entire range for the majority of commercial and institutional buildings.<\/p>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-50245f43c2866397d7dd68934cda2d30 wp-block-paragraph\">If you remember one recommendation from this guide, make it this: <strong>for a typical building fa\u00e7ade or roof in a normal-to-hot climate, HDP over a sound substrate is the rational default.<\/strong> It is the sweet spot where durability, formability and price cross. See specifications and available widths for <a href=\"https:\/\/wanzhisteels.com\/es\/bobina-ppgi\/\" target=\"_blank\" rel=\"noopener\" title=\"\">HDP color coated steel coil<\/a>.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-5aced9b5\"><h2 class=\"uagb-heading-text\">6. PVDF (Polyvinylidene Fluoride): Premium Performance for Harsh Environments<\/h2><\/div>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-d84a6bcb9dd82dff21aa77de576249b8 wp-block-paragraph\">PVDF is the premium end of the ladder and earns it through chemistry. The carbon\u2013fluorine (C\u2013F) bond is one of the strongest in organic chemistry, so a PVDF top coat shrugs off UV, chemicals and pollutants that destroy softer resins. Properly made PVDF holds color and gloss for <strong>20\u201325+ years<\/strong> and meets <strong><a href=\"https:\/\/fgiaonline.org\" target=\"_blank\" rel=\"noopener nofollow\" title=\"\">AAMA 2605 performance requirements<\/a><\/strong> (now maintained by FGIA), the highest durability class for architectural coatings.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-757e8f86\"><h3 class=\"uagb-heading-text\">What is the PVDF 70\/30 vs 50\/50 trap?<\/h3><\/div>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-220e8c9fb23bf88ca1b6bddaf0bfd9f2 wp-block-paragraph\">This is the warning buyers most often miss. Genuine, warrantied PVDF is a <strong>70\/30 resin-to-ceramic (pigment) blend<\/strong> \u2014 about 70% <a href=\"https:\/\/kynar.com\" target=\"_blank\" rel=\"noopener nofollow\" title=\"\">Kynar 500<\/a> \/ Hylar 5000 PVDF resin and 30% ceramic pigment. That resin ratio is what delivers AAMA 2605 performance.<\/p>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-279c2e43cbb477e11c9c617e5c866372 wp-block-paragraph\">Many suppliers invoice &#8220;PVDF&#8221; at a 50\/50 blend, or even lower resin content padded with cheaper polyester, and the panel looks identical on the truck. But a 50\/50 film loses color and gloss years earlier and will not pass AAMA 2605. <strong>Before you pay PVDF prices, confirm the resin brand (Kynar 500 or Hylar 5000) and the \u226570% resin content in writing<\/strong>, backed by a resin certificate from the resin maker \u2014 not just the mill&#8217;s word. See the <a href=\"https:\/\/wanzhisteels.com\/es\/about-ppgi-sheet-coil-common-questions-we-need-to-know\/\" target=\"_blank\" rel=\"noopener\" title=\"\">questions to ask before you approve a PPGI spec<\/a> for a full pre-order checklist.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-7dee8f6a\"><h3 class=\"uagb-heading-text\">The flexibility limitation<\/h3><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">PVDF is also the <strong>least flexible<\/strong> of the four: typical <strong>T4\u2013T5<\/strong> performance. In cold weather, a deeply formed PVDF part can crack at the bend. There is a real case of a cold-storage roof in coastal Vietnam \u2014 a tightly rolled profile deeper than 25 mm \u2014 where a client specified PVDF, watched hairline cracks appear after a single cool season, and had to accept PE or HDP for the re-order. <strong>If the part is deep-drawn or tightly bent, PVDF may be the wrong resin regardless of budget.<\/strong><\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-uagb-image uagb-block-f2e106fe wp-block-uagb-image--layout-default wp-block-uagb-image--effect-static wp-block-uagb-image--align-none\"><figure class=\"wp-block-uagb-image__figure\"><img decoding=\"async\" src=\"https:\/\/wanzhisteels.com\/wp-content\/uploads\/2026\/08\/SMP-coated-PPGI-corrugated-steel-sheet.jpg\" alt=\"SMP coated PPGI corrugated steel sheet\" class=\"uag-image-28577\" width=\"480\" height=\"360\" title=\"SMP coated PPGI corrugated steel sheet\" loading=\"lazy\" role=\"img\" \/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-5a30a6c0\"><h3 class=\"uagb-heading-text\">PE PPGI board<\/h3><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-uagb-image uagb-block-ffd506a5 wp-block-uagb-image--layout-default wp-block-uagb-image--effect-static wp-block-uagb-image--align-none\"><figure class=\"wp-block-uagb-image__figure\"><img decoding=\"async\" src=\"https:\/\/wanzhisteels.com\/wp-content\/uploads\/2026\/08\/Comparison-of-PE-vs-SMP-vs-HDP-vs-PVDF-coatings-with-PPGI-corrugated-steel-sheets-and-corrugated-roofing-sheets.jpg\" alt=\"Comparison of PE vs SMP vs HDP vs PVDF coatings with PPGI corrugated steel sheets and corrugated roofing sheets.\" class=\"uag-image-28578\" width=\"480\" height=\"360\" title=\"Comparison of PE vs SMP vs HDP vs PVDF coatings with PPGI corrugated steel sheets and corrugated roofing sheets.\" loading=\"lazy\" role=\"img\" \/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-342ccac8\"><h3 class=\"uagb-heading-text\">HDP Coated Roof sheet<\/h3><\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-uagb-image uagb-block-bc5a18d4 wp-block-uagb-image--layout-default wp-block-uagb-image--effect-static wp-block-uagb-image--align-none\"><figure class=\"wp-block-uagb-image__figure\"><img decoding=\"async\" src=\"https:\/\/wanzhisteels.com\/wp-content\/uploads\/2026\/08\/PVDF-coated-PPGL-corrugated-steel-sheet-corrugated-roofing-sheet.jpg\" alt=\"PVDF-coated PPGL corrugated steel sheet, corrugated roofing sheet\" class=\"uag-image-28579\" width=\"480\" height=\"360\" title=\"PVDF-coated PPGL corrugated steel sheet, corrugated roofing sheet\" loading=\"lazy\" role=\"img\" \/><\/figure><\/div>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-25cd01f8\"><h3 class=\"uagb-heading-text\">PVDF PPGL Roofing<\/h3><\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-e6f58e7c\"><h2 class=\"uagb-heading-text\">7.

Frequently Asked Questions<\/h2><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q1. Which coating lasts longest on color coated steel?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">PVDF lasts longest at 20\u201325+ years of exterior service, meeting AAMA 2605. HDP follows at 15\u201320 years. PE and SMP are shorter-lived at 7\u201315 years. Longevity also depends on substrate and climate, not coating alone.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q2. Is PVDF always worth the higher price?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">No. PVDF&#8217;s premium is justified for coastal, industrial or long-life prestige projects, but it is the least flexible resin (T4\u2013T5) and can crack on deep-formed parts. For a normal building in a moderate climate, HDP delivers most of the benefit at far lower cost.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q3. What does &#8220;70\/30 PVDF&#8221; mean and why does it matter?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">It means 70% PVDF resin (Kynar 500 \/ Hylar 5000) and 30% ceramic pigment \u2014 the blend that earns AAMA 2605. Suppliers sometimes substitute a 50\/50 or polyester-diluted mix at PVDF prices; always demand a resin certificate proving \u226570% content.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q4. Can I use PE on a roof in a hot, sunny climate?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">You can, but expect chalking and noticeable color fade within 7\u201310 years, often sooner under intense UV. For sun-exposed roofs, HDP is the value choice and PVDF the premium one. PE suits formed, budget-limited or short-tenure buildings.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q5. Does the substrate matter as much as the coating?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-39cc36544c9c2df786e3b33bcddd9807 wp-block-paragraph\">Yes. Coating protects appearance; substrate protects structure. Coastal and industrial sites need <a href=\"https:\/\/wanzhisteels.com\/es\/gi-gl\/\" target=\"_blank\" rel=\"noopener\" title=\"\">Galvalume (AZ150)<\/a> under PVDF. A premium top coat over weak galvanized steel still fails at the cut edge in salt spray.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q6. What film thickness should I specify in the contract?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">Top coat 20 \u00b5m minimum, 25 \u00b5m for premium\/PVDF systems; back coat 8\u201310 \u00b5m. Write &#8220;top\/back coat microns&#8221; into the purchase order and require a third-party film-thickness report before shipment.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q7. How do EN 10169 RC\/Ruv grades map to my site?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">RC1\u2013RC2 covers low-corrosion inland use; RC4\u2013RC5+ covers coastal and industrial severity. Ruv2 is moderate UV, Ruv4\u2013Ruv5 is extreme. Match your climate to these grades, then pick the coating and substrate from the selection matrix.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-aioseo-faq\" data-schema-only=\"false\"><h3 class=\"aioseo-faq-block-question\"><strong>Q8. Why might PVDF crack during installation?<\/strong><\/h3><div class=\"aioseo-faq-block-answer\">\n<p class=\"wp-block-paragraph\">PVDF has the lowest flexibility of the four resins (T4\u2013T5). Deep drawing, tight roll-forming, or bending in cold weather can open hairline cracks. If the profile is complex or the site is cold, choose PE, SMP or HDP instead.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-cf16a245\"><h2 class=\"uagb-heading-text\">Resumen<\/h2><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Choosing between <strong>PE vs SMP vs HDP vs PVDF<\/strong> comes down to one rule: specify for the climate you have, not the budget you wish you had. Match the coating to the site, pair it with the right substrate, write the microns into the contract, and confirm the resin proof for PVDF. Do that, and your building will still look new when the cheaper alternative next door has already been re-coated.<\/p>\n\n\n\n<p class=\"has-ast-global-color-2-color has-text-color has-link-color wp-elements-d7f8662244bab185099ca90f22a73dd4 wp-block-paragraph\">For current mill pricing with resin certification and sample lead times, <a href=\"#ds-open-popup-1\" title=\"\">request a free quote<\/a> or download the full PPGI specification sheet from our team.<\/p>\n\n\n\n<div class=\"wp-block-uagb-social-share uagb-social-share__outer-wrap uagb-social-share__layout-horizontal uagb-block-95e4268d\">\n<div class=\"wp-block-uagb-social-share-child uagb-ss-repeater uagb-ss__wrapper uagb-block-811cb1e9\"><span class=\"uagb-ss__link\" data-href=\"https:\/\/www.facebook.com\/sharer.php?u=\" tabindex=\"0\" role=\"button\" aria-label=\"facebook\"><span class=\"uagb-ss__source-wrap\"><span class=\"uagb-ss__source-icon\"><svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 512 512\"><path d=\"M504 256C504 119 393 8 256 8S8 119 8 256c0 123.8 90.69 226.4 209.3 245V327.7h-63V256h63v-54.64c0-62.15 37-96.48 93.67-96.48 27.14 0 55.52 4.84 55.52 4.84v61h-31.28c-30.8 0-40.41 19.12-40.41 38.73V256h68.78l-11 71.69h-57.78V501C413.3 482.4 504 379.8 504 256z\"><\/path><\/svg><\/span><\/span><\/span><\/div>\n\n\n\n<div class=\"wp-block-uagb-social-share-child uagb-ss-repeater uagb-ss__wrapper uagb-block-e5fbb157\"><span class=\"uagb-ss__link\" data-href=\"https:\/\/twitter.com\/share?url=\" tabindex=\"0\" role=\"button\" aria-label=\"twitter\"><span class=\"uagb-ss__source-wrap\"><span class=\"uagb-ss__source-icon\"><svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 448 512\"><path d=\"M400 32H48C21.5 32 0 53.5 0 80v352c0 26.5 21.5 48 48 48h352c26.5 0 48-21.5 48-48V80c0-26.5-21.5-48-48-48zm-48.9 158.8c.2 2.8 .2 5.7 .2 8.5 0 86.7-66 186.6-186.6 186.6-37.2 0-71.7-10.8-100.7-29.4 5.3 .6 10.4 .8 15.8 .8 30.7 0 58.9-10.4 81.4-28-28.8-.6-53-19.5-61.3-45.5 10.1 1.5 19.2 1.5 29.6-1.2-30-6.1-52.5-32.5-52.5-64.4v-.8c8.7 4.9 18.9 7.9 29.6 8.3a65.45 65.45 0 0 1 -29.2-54.6c0-12.2 3.2-23.4 8.9-33.1 32.3 39.8 80.8 65.8 135.2 68.6-9.3-44.5 24-80.6 64-80.6 18.9 0 35.9 7.9 47.9 20.7 14.8-2.8 29-8.3 41.6-15.8-4.9 15.2-15.2 28-28.8 36.1 13.2-1.4 26-5.1 37.8-10.2-8.9 13.1-20.1 24.7-32.9 34z\"><\/path><\/svg><\/span><\/span><\/span><\/div>\n\n\n\n<div class=\"wp-block-uagb-social-share-child uagb-ss-repeater uagb-ss__wrapper uagb-block-3fda4fb5\"><span class=\"uagb-ss__link\" data-href=\"https:\/\/pinterest.com\/pin\/create\/link\/?url=\" tabindex=\"0\" role=\"button\" aria-label=\"pinterest\"><span class=\"uagb-ss__source-wrap\"><span class=\"uagb-ss__source-icon\"><svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 448 512\"><path d=\"M448 80v352c0 26.5-21.5 48-48 48H154.4c9.8-16.4 22.4-40 27.4-59.3 3-11.5 15.3-58.4 15.3-58.4 8 15.3 31.4 28.2 56.3 28.2 74.1 0 127.4-68.1 127.4-152.7 0-81.1-66.2-141.8-151.4-141.8-106 0-162.2 71.1-162.2 148.6 0 36 19.2 80.8 49.8 95.1 4.7 2.2 7.1 1.2 8.2-3.3 .8-3.4 5-20.1 6.8-27.8 .6-2.5 .3-4.6-1.7-7-10.1-12.3-18.3-34.9-18.3-56 0-54.2 41-106.6 110.9-106.6 60.3 0 102.6 41.1 102.6 99.9 0 66.4-33.5 112.4-77.2 112.4-24.1 0-42.1-19.9-36.4-44.4 6.9-29.2 20.3-60.7 20.3-81.8 0-53-75.5-45.7-75.5 25 0 21.7 7.3 36.5 7.3 36.5-31.4 132.8-36.1 134.5-29.6 192.6l2.2 .8H48c-26.5 0-48-21.5-48-48V80c0-26.5 21.5-48 48-48h352c26.5 0 48 21.5 48 48z\"><\/path><\/svg><\/span><\/span><\/span><\/div>\n\n\n\n<div class=\"wp-block-uagb-social-share-child uagb-ss-repeater uagb-ss__wrapper uagb-block-1e6802a9\"><span class=\"uagb-ss__link\" data-href=\"https:\/\/www.linkedin.com\/shareArticle?url=\" tabindex=\"0\" role=\"button\" aria-label=\"linkedin\"><span class=\"uagb-ss__source-wrap\"><span class=\"uagb-ss__source-icon\"><svg xmlns=\"https:\/\/www.w3.org\/2000\/svg\" viewbox=\"0 0 448 512\"><path d=\"M416 32H31.9C14.3 32 0 46.5 0 64.3v383.4C0 465.5 14.3 480 31.9 480H416c17.6 0 32-14.5 32-32.3V64.3c0-17.8-14.4-32.3-32-32.3zM135.4 416H69V202.2h66.5V416zm-33.2-243c-21.3 0-38.5-17.3-38.5-38.5S80.9 96 102.2 96c21.2 0 38.5 17.3 38.5 38.5 0 21.3-17.2 38.5-38.5 38.5zm282.1 243h-66.4V312c0-24.8-.5-56.7-34.5-56.7-34.6 0-39.9 27-39.9 54.9V416h-66.4V202.2h63.7v29.2h.9c8.9-16.8 30.6-34.5 62.9-34.5 67.2 0 79.7 44.3 79.7 101.9V416z\"><\/path><\/svg><\/span><\/span><\/span><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Specifying the wrong coating on a color coated steel project is rarely a visible mistake on day one \u2014 but it is an expensive one by year five.
