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.

The appearance of black rust on the surface of galvanized steel is an indication that the underlying steel has corroded. This problem occurs during storage and use, usually due to overstorage, poor passivation of the oil coating, or environmental corrosion that exceeds the corrosion resistance of the zinc coating. Unlike white and red rust on

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
In the field of metal corrosion protection, hot-dip galvanized steel (GI) and galvalume (GL) play an important role as metal raw materials for roofing/wall/partition processing, home appliance manufacturing, industrial production, etc., because of their excellent corrosion resistance and long service life in general indoor, marine, and chemical environments. So when should you choose galvanized products
