1, Galvanized steel sheet metal bending parts or galvanealed steel, which is galvanized then annealed. Galvanization is the process of applying a protective zinc coating to steel in order to prevent rust and corrosion. Annealing is a heat treatment process that alters the microstructure of a material to change its mechanical or electrical properties, typically reducing the hardness and increasing the ductility for easier fabrication. 2.Product Feature for Galvanized Steel Sheet Metal Bending Parts Material: Galvanized Sheet Thickness: 2.5mm Surface: industrial surface Size: 1703mm*80mm*40mm Tolerance: 0.5 Weight: 5.1kg Process: laser cutting, bending Application: water treatment equipment 3.Product Details for Galvanized Steel Sheet Metal Bending Parts Why Galvanized Steel Sheet Metal Bending Parts? Depending on the application, sheet metal offers advantages, not just over non-metal alternatives but over other types of metal fabrication as well. Compared to machining, it generally has a significantly lower material cost. Rather than starting with a block of material, much of which will be machined away, sheet metal lets you buy what you need and use what you need. The remainder of a metal sheet is still usable, while swarf the shavings removed in machining must be recycled.
