Industrial building supplies galvanized machine welding steel grating
Steel bar grating with high strength and firm structure is made up of carbon steel, aluminum steel, or stainless steel. According to the manufacturing methods, it can be divided into four types: welded, press-locked, swage-locked, and riveted gratings. According to the surface shapes, it can be divided into smooth and serrated gratings. With various styles and sizes for choice, steel gratings are widely used in everyday life, such as stair treads, walkways, platforms, floors, various covers, wheeled equipment, security screens, heavy-duty constructions, and so on.
Platform steel grid plate is made of flat steel in accordance with a certain distance and cross bar arrangement, and welded into a kind of steel products with a square grid in the middle, mainly used to do drain cover plate, steel structure platform plate,steel ladder step plate.The bar is generally made of twisted square steel.
Platform hot dip galvanized steel grid plate is generally made of
carbon steel, hot dip galvanized surface, can play a role in
preventing oxidation.It can also be made of stainless steel.Hot dip
galvanized steel grid has ventilation, lighting, heat
dissipation, anti-skid, explosion-proof and other properties.
