Galvanized steel grating cover plate is a very widely used cover plate, not only in the city, but also in the countryside. Galvanized grid plate is generally made of carbon steel. The appearance of hot-dip galvanizing can prevent oxidation. It can also be made of stainless steel. The steel grating has ventilation, daylighting, heat dissipation, antiskid, explosion-proof and other properties. Galvanized steel grating is a kind of steel product which is arranged with flat steel according to a certain distance and cross beam and welded to the square grid in the middle by pressure welding machine or manual welding. Galvanized steel grating is mainly used for making ditch cover plate, steel structure platform plate and steel ladder step plate. The horizontal bar is usually used after the square steel is twisted.
The features of galvanized grid cover plate are as follows:
The mesh pressure welding structure is firm, which makes it have high load, light structure and easy to carry;
酸碱的腐蚀能力在ph6 ~ ph12.5范围内。锌层表面形成稳定的保护膜，具有良好的耐腐蚀性。
The corrosion capacity of acid and alkali is in the range of ph6 ~ ph12.5. A stable protective film is formed on the surface of zinc layer, which has good corrosion resistance.
With high strength, corrosion resistance, maintenance free and other characteristics, the unique combination of uniform precision, light and elegant structure, natural harmony, elegant style.
In rural areas, some novices who buy hot-dip galvanized steel grating cover plate are not familiar with the galvanized steel plate cover plate, and pits are easy to appear in the selection of some manufacturers. So what is the trench cover of galvanized iron sheet? Before choosing, we should know
1. Load bearing flat steel: the width of flat steel is 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 60mm, 65mm and other common specifications.
2. Thickness of lifting flat steel: 2.5mm-6.0mm and other common specifications.
3. Distance between flat steel of scale lifting: small distance of 15mm, large distance of 100mm. The common ones are 30mm, 40mm and 50mm.
4. Spacing of torsion bar: 30mm-200mm. Most users use 100mm, 50mm spacing is common.
5. From the production process: press welding steel grid plate, insert steel grid plate.
6. Appearance treatment: hot galvanizing, cold galvanizing, painting, etc. hot galvanizing is commonly used.
