Pre-coated metal refers to products coated with organic coatings on metal materials, including steel, aluminum, copper, and zinc alloys. Pre-coated steel is a type of pre-coated metal, specifically referring to steel substrates coated with colored coatings. Both types of pre-coated metals enhance corrosion resistance, wear resistance, decorative properties, and weather resistance through a protective coating. […]

Galvanized Steel coil sheet is a pure zinc coating applied to the surface of a carbon steel sheet, which is available in a wide variety of choices, and therefore there are many types of galvanized steel. There are five grades of galvanized steel: commercial, structural, deep-drawn, ultra-deep-drawn, and high-strength structural, depending on the design strength,

AluZinc (also known as Galvalume, Zincalume, or 55% Al-Zn alloy coated steel) represents a revolutionary leap in corrosion protection technology for steel substrates. Combining the barrier resistance of aluminum with the sacrificial protection of zinc, this material has become the gold standard for long-life, low-maintenance metal solutions across industries. Here’s a comprehensive analysis of its science, standards, and applications.

Sandwich panels are a kind of composite panels with thermal and acoustic insulation and fire prevention and corrosion prevention and other efficacies, in which the bending strength of metal sandwich panels can reach 100~300 MPa, realizing the perfect combination of lightweight, high strength and multi-functionality. What is Sandwich Panel? Sandwich panels, are composite structures consisting
