Product description Spray painted steel grating mainly for the surface treatment of steel grid plate, steel grid plate general surface treatment is hot dip galvanizing.The same surface painting is an important one. The processing cost of painted steel grid plate is lower than hot dip galvanized. rust resistance, more afraid of wear, but paint can choose a variety of colors, especially when the steel grid plate for mechanical equipment, the color of the steel grid plate and the color of the equipment is required. So we use spray paint to do the surface treatment. Steel grid plate is composed of negative flat steel and twist steel according to a certain distance of longitude and latitude arrangement, welding into the original plate, after cutting edge grinding cutting mouth surface painting and other processes of deep processing and customer requirement of finished product. Its characteristics are: high bearing capacity, light weight easy to lift and other characteristics; beautiful appearance, ventilation and durability; paint surface treatment makes it has a good anti-corrosion ability, beautiful surface gloss; good ventilation, daylighting, heat dissipation, explosion-proof and skid proof performance; prevent the accumulation of dirt. Widely used in power plants, water plants, sewage treatment plants, petrochemical municipal projects , sanitation projects and other fields of steel grid platform, walkway, trestle, ditch cover, well cover, ladder, fence, guardrail and so on.
