Wanzhi supplies green color coated aluminum steel to Guyanese builders

Wanzhi anti fingerprint Galvalume steel delivered Guyana

Projects /

Guyana’s tropical maritime climate poses a severe challenge to building materials – high humidity and strong salt spray corrosion significantly reduce the lifespan of ordinary steel. Recently, Wanzhi Company provided green anti fingerprint galvalume steel coils for a high-end residential project in Georgetown, Guyana, which were highly recognized by customers for their excellent weather resistance and aesthetics. Product Introduction The green fingerprint resistant PPGL steel coil this time includes a triple protection system: 55% aluminum zinc alloy coating (compliant with ASTM A792 standard), nano anti fingerprint coating technology (reducing fingerprint residue by 90%), environmentally friendly green coating, perfectly adapted to the tropical climate environment of Guyana. RAL 6027 PPGL steel […]

Is Galvalume superior to galvanized in all conditions

NEWS /

The corrosion resistance of aluminum zinc coated coils (such as 55% aluminum zinc alloy, commonly known as Galvalume) is superior to that of ordinary galvanized coils (pure zinc coating) in most environments, but not all environments are suitable. Its advantages and limitations need to be analyzed in conjunction with specific corrosion conditions. Comparison of Corrosion Resistance with Galvalume vs Galvanized Environment Type Aluminum Zinc (AZ/GL) Galvanized (GI) performance Conclusion Neutral/alkaline atmosphere The oxide film of aluminum (Al ₂ O3) is dense and stable, with excellent corrosion resistance Sacrificial protection of zinc layer, but faster corrosion rate AZ is significantly better than GI Weak acid environment (pH 4-6) Aluminum film partial

This means it can withstand great pressure and deformation without damage, and its strength is almost double that of ordinary steel (such as G250/G300). “AZ150” refers to its surface coating, which is an alloy of 55% aluminum, 43.4% zinc and 1.6% silicon, and the weight of the coating per square meter is as high as 150 grams. This alloy coating is the

Its core advantages include: Extraordinary corrosion resistance: Aluminum forms a dense oxidation barrier to isolate moisture, while zinc provides “sacrificial protection”, especially in salt spray and industrial environments, with a lifespan 3-6 times longer than galvanized steel. High temperature stability: Aluminum composition endows excellent heat resistance (reflecting 80% of heat), significantly reducing the internal temperature of buildings.

Differences between PPGI and PPGL

NEWS /

Comparison Between PPGI and PPGL PPGI and PPGL are two different coating technologies with certain differences in application and performance. PPGI is a technology that uses zinc as a matrix and coats a layer of color pigment on the zinc surface, which is suitable for lighter environmental conditions. PPGL, on the other hand, uses aluminum zinc as a matrix and coats a layer of color pigment on the aluminum zinc surface, which has better corrosion resistance and is suitable for harsh environmental conditions. This is the main difference between PPGI and PPGL, which will further affect their functions and applications. PPGL sheet has better heat resistance than PPGI sheet. PPGL
