Suitable for alloy steel grating, building materials, power plants, boilers, shipbuilding, petrochemical, chemical and general industrial plants, municipal construction and other industries, with air and light, non-slip, bearing capacity is strong, beautiful and durable, easy to clean, easy to install and so on. Loaded flat pitch: two adjacent bearing bars by the center distance, commonly 30MM, 40MM two kinds. Steel grating bar spacing: distance between the centers of two adjacent rails usually 50MM, 100, two kinds, according to customer requirements. Compared with steel grating pattern plates and other grille, steel grating has the following advantages: steel grating material savings: bear the same way most provinces material loading conditions, and accordingly, can reduce material support structure. Steel grating reduced investment: saving materials, the provincial labor, the provincial period, free cleaning and maintenance. Steel grating construction is simple: in the pre-installed on the support given country or welding clamp bolt fixing, one person to complete. Grating period savings: Products without on-site reprocessing, installation is very quick. Durable steel grating: the factory hot-dip zinc corrosion treatment, impact resistance and weight of ability. Steel grating modern style: appearance, design specifications, air and light, giving the overall sleek, contemporary feel. Steel grating structure light: less timber, light structure, and easy lifting. Steel grating against product contamination: no accumulation of rain, snow and dust. Steel grating reduce drag: because good ventilation, windy wind resistance and reduce wind damage. Design is simple: no small beam, simple structure, designed to simplify; no detail design of steel lattice panels, you can only specify the model, the manufacturer of steel grating customers can design discharge board plans. Good ventilation, lighting, cooling, explosion-proof, non-slip performance: acid corrosion: Within PH 6 to PH 12.5 range, the zinc layer on the surface of the protective film to form a stable, good corrosion resistance.
