Grating is a kind of net structure product with protective, filtering, and load-bearing functions, with diverse materials and structures, suitable for different scenarios.
　　Core Product Introduction
　　Definition and Classification：Grating is a net-like material made of metal, FRP, plastic, etc., through welding, weaving, molding, etc., with three major categories —— metal gratings (carbon steel, stainless steel, aluminum alloy), FRP gratings, plastic gratings, each type focusing on different properties.
　　Core Features:
　　Metal Type：High strength, load-bearing capacity, heat resistance (stainless steel can withstand above 500℃), but carbon steel is prone to rust (need anti-corrosion treatment).
　　FRP Type：Lightweight and high-strength (density is only 1/4 of steel), corrosion resistance, non-conductive, acid and alkali resistance environment.
　　Plastic Type：Low cost, light weight, easy to install, moisture resistance but weak load-bearing and high-temperature resistance.
　　Core Functions：Mainly used for protection and isolation, filtering and screening, load-bearing and support, drainage and ventilation, and also has certain decorative properties, can replace traditional boards in some scenarios.
　　Key Technical Parameters
　　Material Parameters:
　　Metal Type: Carbon Steel (Q235), Stainless Steel (304/316), Aluminum Alloy (6061), thickness 0.5-10mm (wire diameter / plate thickness).
　　FRP Type: Resin (unsaturated polyester resin, epoxy resin) + glass fiber, grating thickness 25-50mm.
　　Plastic Type: PP, PE, PVC, wire diameter 2-8mm, grating thickness 10-30mm.
　　Structural Parameters:
　　Mesh Specifications: Metal woven net (hole pitch 1-50mm), welded grating (grid 50×50mm-200×200mm), molded grating (38×38mm-50×50mm).
　　Size Specifications: Single piece size 1×2m, 1.22×2.44m, 1.22×3.66m (can be customized for cutting), length can reach 6m.
　　Performance Parameters:
　　Bearing Capacity: Metal grating (200-1000kg/㎡), fiberglass grating (100-500kg/㎡), plastic grating (50-200kg/㎡).
　　Temperature Range: Metal (-20℃~800℃), FRP (-50℃~120℃), Plastic (-30℃~80℃).
　　Anti-corrosion Performance: Stainless steel / FRP / Plastic can withstand acid and alkali, carbon steel needs hot-dip galvanization / spray painting treatment (anti-corrosion service life 5-15 years).
　　Other Parameters: Surface treatment (Metal: hot-dip galvanization, cold-dip galvanization, spray painting; FRP: anti-slip pattern, flame retardant treatment), flame retardant grade (some scenarios can reach B1 grade).
　　Typical Use Scenarios
　　Industrial field: workshop platform pedals, equipment protective nets, sewage filtration grilles, mining screening nets.
　　Municipal engineering: urban road manhole covers, tree pool grilles, drainage ditch covers, bridge protective nets.
　　Building decoration: stair treads, balcony guardrails, ceiling decorative mesh, curtain wall grilles.
　　Other scenes: farm fence, orchard protective net, parking lot ground grille, ship deck pedals.
