Painted steel grating is in accordance with a certain distance and crossbar (twisted steel, square steel, round, flat, etc.) with a flat cross-arranged and welded into an intermediate steel products with a square lattice, steel Georgia moderators do use drain cover, steel platform board, ladders stepping board. After twisted rails commonly used square steel. Grating commonly used steel production, appearance paint treatment, can serve to prevent oxidation. Can also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof properties. Painted steel grating production methods: by painting steel grating load flat steel and bars with certain distances, using 200 tons of hydraulic resistance welding automation equipment welded into the original board, after cutting, opening, edging and other processes processing and to customer requirements. Loaded flat pitch: two adjacent bearing bars by the center distance, commonly 30MM, 40MM two kinds. Bar spacing: distance between the centers of two adjacent rails usually 50MM, 100, two kinds, according to customer requirements. Compared with the tread plate and other grille, painted steel grating steel grating has the following advantages: saving materials: withstand the same way most provinces material loading conditions, and accordingly, can reduce material support structure. Reduce investment: saving materials, the provincial labor, the provincial period, free cleaning and maintenance. Construction is simple: in the pre-installed on the support given country or welding clamp bolt fixing, one person to complete. Save duration: Products without on-site reprocessing, installation is very quick. Durable: the factory and paint surface treatment, rust and oxidation strong. Modern style: paint treatment, depending on the application can choose the color, appearance, design specifications, air and light, giving the overall sleek, contemporary feel. Lightweight construction: timber less, light structure, and easy lifting. Reduce wind resistance: Due to good ventilation, windy wind resistance and reduce wind damage. Against product contamination: no accumulation of rain, snow and dust. Ventilation, lighting, cooling, explosion-proof, non-slip performance is good design is simple: no small beam, simple structure, designed to simplify; no detail design of steel lattice panels, you can only specify the model, customers can design the factory exhaust plate map.
