Product details

Specially engineered for demanding construction applications, our premium galvanized steel coils deliver unmatched durability and weather resistance. Manufactured using advanced continuous hot-dip technology, these coils feature a tightly bonded zinc coating (Z90-Z275) that provides superior corrosion protection even in harsh environments. The optimized spangle control ensures consistent surface quality for both structural and aesthetic applications, from roofing and wall cladding to steel framing systems.

Galvalume steel plates are coated with 55% aluminum-zinc alloy technology, perfectly integrating the corrosion resistance of aluminum and the cathodic protection advantages of zinc, providing superior corrosion resistance than ordinary galvanized plates (salt spray test lasting over 3,000 hours). Its unique aluminum-zinc-silicon coating structure has excellent high-temperature resistance (long-term tolerance to 315℃ high temperature), making it particularly suitable for the roof and wall systems of industrial plants, warehousing and logistics buildings, etc. The unique silver fish-scale crystalline pattern on the product surface combines functionality and decoration, with a reflectivity of over 75%, which can significantly reduce building energy consumption.

Galvanized Steel,The most widely used metal in the construction field, provides reliable protection for various building envelope systems through strict zinc coating weight control (Z60-Z275). The chromium-free passivation treatment process is adopted, which complies with environmental protection standards. The self-healing property of the coating ensures that the cut area still has anti-corrosion function. The product offers various surface forms such as regular zinc flowers and small zinc flowers, and is suitable for application scenarios that require long-term weather resistance, such as steel structures and ventilation ducts. Its service life can reach over 25 years.

Aluminum Coil/Pipe/Plate building-grade aluminum alloy products are made of high-quality alloys such as 3003/5052 and achieve an excellent strength-to-weight ratio (tensile strength up to 150-300 mpa) through precise rolling processes. Its natural oxide film protection keeps the product stable in damp, acidic and alkaline environments, making it particularly suitable for outdoor building applications such as curtain wall systems and sunrooms. It can provide multiple hardness states such as H14/H24, support surface treatments such as anodizing and spraying, meet different architectural aesthetic requirements, and the 100% recyclable feature is more in line with green building standards.

Stainless steel 304/316L stainless steel plates, with an alloy composition of more than 18% chromium, provide permanent anti-corrosion solutions for high-end construction projects. The surface can be processed into different finishes such as 2B, BA, and HL, making it particularly suitable for harsh environments like coastal building curtain walls and decorative lines. The product has passed the ASTM A240 certification. The corrosion resistance of 316L stainless steel containing molybdenum in the chloride ion environment is more than three times higher than that of 304, and it is an ideal material choice for landmark buildings.

Aluzinc Steel aluminum-zinc-silicon alloy coated steel plate (55%Al-Zn), through its unique microstructure design, has an anti-corrosion performance 4 to 6 times that of pure zinc coating under the same coating thickness. Its outstanding heat resistance (up to 400℃) makes it particularly suitable for high-temperature environments such as industrial plants. The unique bright silver luster on its surface requires no additional decorative treatment. The product has passed the ASTM A792 certification. The coating has strong adhesion and can meet the strict processing and forming requirements.

Prepainted Steel,The pre-coated steel plates are coated with environmentally friendly polyester, silicon-modified polyester or PVDF coatings, and a film thickness of over 20μm is controlled through a precise roller coating process. The product offers over 200 standard color cards to choose from. Weather-resistant products can ensure no fading for more than 15 years (passing the 5,000-hour QUV test). The special back coating system ensures double-sided anti-corrosion and is suitable for building parts such as metal roofs and curtain walls that have high requirements for color durability. The factory prefabrication feature can reduce on-site construction losses by more than 30%.
