Blue PPGI roofing sheets (also known as blue corrugated roofing sheets) are a building material made from galvanized steel (GI) sheets. After pre-treatment, the surface is sprayed with a blue organic coating (such as polyester or PVDF), then baked, cured, and cold-pressed into a corrugated pattern (such as trapezoidal or sinusoidal). The corrugated design (15-50mm in height) combines structural strength with drainage, making it suitable for a variety of building and construction applications. The blue color adds a touch of vitality, complementing any architectural design.

Weatherproof and Corrosion-Resistant
Dual Protection: The galvanized layer blocks electrochemical corrosion, while the organic coating (PE/SMP/PVDF) resists UV rays and salt spray, resulting in a service life exceeding 15 years.
Excellent Color Retention: High-quality coatings (such as PVDF) maintain color retention >90%, ensuring the blue color lasts for decades without excessive fading.

Structural Performance
High Strength and Compressive Resistance: The corrugated design enhances rigidity, allowing it to withstand strong wind pressure (0.6mm or thicker panels are suitable for high-wind areas) and snow loads.
Lightweight: Weighing only 1/5 of traditional tiles, this reduces transportation and structural support costs.

Functional Design
Efficient Drainage: The corrugated design expedites rainwater drainage and reduces water accumulation.
Insulation and Noise Reduction: The air layer blocks heat conduction, while the corrugated structure reduces raindrop noise.

Construction and Economical Efficiency
Quick Installation: Self-tapping screws connect directly to the steel structure, reducing construction time by 40%.
Low-Cost Maintenance: The self-cleaning surface eliminates the need for frequent maintenance.

We are an integrated industrial and trade company that can produce steel independently and reduce costs.

From raw materials to finished products, we control quality throughout the process to ensure that the products meet customer requirements.

The combination of production and sales confidentiality can respond to orders quickly and shorten delivery time.

One-stop service, from consultation to production, and finally to after-sales service, provides all-round support.

We are self-produced, reducing dependence on external price fluctuations. In the face of sudden price increases, we can still deliver quickly and on time.

For inventory steel, we can provide preferential prices.
