The thickness of galvanized steel sheet refers to the thickness of the base metal (substrate), excluding the thickness of the surface zinc layer. There are several ways to express this thickness; some regions commonly use “gauge” (abbreviated as GA), while others use metric units (mm). Both methods are widely used in the field of metal […]

Galvanized structural steel is ubiquitous in construction projects and industrial facilities. Leveraging its high strength for load-bearing and long-lasting corrosion resistance, it serves as the skeletal material providing structural support and decorative functions across various building components. Based on its role in construction, it can be categorized into four types: primary structural steel, secondary structural

Galvanized steel tube leverage dual advantages in corrosion resistance and structural integrity. Their distinct cross-sectional forms—round pipes and square/rectangular pipes—precisely meet diverse demands ranging from fluid transportation to framework support. Round pipes, with their uniform stress distribution and smooth inner walls, specialize in conveying water, gas, oil, and other fluids. Square and rectangular pipes, meanwhile,

Galvanized wire, a metal wire with excellent corrosion resistance, is one of the most basic yet indispensable materials in construction, agriculture, industrial manufacturing, and everyday hardware. It is widely used in construction binding, agricultural greenhouses, and industrial protection. Galvanized wire can be divided into galvanized hard wire and galvanized soft wire according to its material

What is VCM Sheet? VCM Sheet consists of three layers: substrate, adhesive, and film. The substrate provides structural strength, while the film offers scratch resistance, yellowing resistance, decorative appeal, and rust prevention. Substrate Layer: Cold-rolled steel sheet (SPCC) or hot-dip galvanized sheet (DX51D+Z). Bonding Layer: Water-based or solvent-based adhesive. Coating Layer: PET, PVC, or PETG

What is Zinc-Aluminum-Magnesium (ZAM) Steel? Zinc-Aluminum-Magnesium steel is a new high-performance steel material. It features a special alloy coating composed of zinc (Zn), aluminum (Al), magnesium (Mg), and trace elements applied via hot-dip galvanizing onto a low-carbon steel substrate. The inclusion of magnesium enables corrosion products to actively migrate and cover cuts, holes, or

Color-coated steel has a service life of 8 to 30 years. Not only does the coating material play a crucial role, but its precise multi-layer coating structure is also the secret to the sheet’s longevity. The typical coating structure of color-coated steel consists of a pretreatment layer (passivation layer), primer, and topcoat. Together, they form
