25X3mm Serrated Galvanized Steel Grating Ramp Rebar Removable Steel Grating
Steel grating can be manufactured through manual welding or machine welding processes, arranging bearing bars and cross bars in longitude and latitude order at specific distances. Cross bars are pressed into bearing bars using high-tension resistance welding controlled by molds or computer systems.
Flat steel is typically cold-rolled Q235 flat steel, but can also include hot-rolled I flat steel, tooth flat steel, inclined flat steel, stainless steel flat steel, and other specifications. Bars generally consist of twisted square steel, square steel, round steel, flat steel, etc. Surface treatments include: hot galvanizing, cold galvanizing, spray modeling, painting, and dip anti-rust oil to prevent oxidation and rust (stainless steel typically doesn't require these treatments, with most stainless steel surfaces receiving polishing treatment).
