Steel grating is in accordance with a certain distance and crossbar (twisted steel, square steel, round, flat, etc.) with a flat cross arrangement, and welded into the middle of a square lattice of steel products with a steel grid moderators do use drain cover, steel platform board, ladders stepping board. After twisted rails commonly used square steel. Grating commonly used carbon steel, galvanized exterior, can serve to prevent oxidation. Can also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof properties. Production standard steel grating: China YB4001-1991, YB / T4001-1998, YB / T4001.1-2007 standard (Chinese for 2007 the latest version of the standard steel grating); in addition the United States, Britain, Australia and New Zealand also have their own standards, in accordance with the United Kingdom and the United States BS4592-1-1995 ANSI / NAAMM (MBG531-88) and other standards. Steel standards in accordance with GB700-88, GB1220-92. Grating Surface treatment: hot dip galvanized, cold galvanizing, painting, anti-rust oil soaked, not processed (usually stainless steel without treatment). Steel grating fabrication method bonding steel grating is the load flat steel and bars with certain distances, using 200 tons of hydraulic resistance welding automation equipment welded into the original board, processed through cutting, opening, edging and other processes from 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. Advantages of saving material: bearing manner under the same load conditions most economical material, and accordingly, can reduce the material of the 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 hot-dip zinc corrosion protection, impact resistance and weight of ability. Modern style: appearance, design specifications, air and light, giving the overall sleek, contemporary feel. Lightweight construction: timber less, light structure, and easy lifting. Against product contamination: no accumulation of rain, snow and dust. Reduce wind resistance: Due to 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, customers can design the factory exhaust plate map. 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. Grating use suitable 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. The new bridge steel grating has been widely used in domestic and foreign businesses, mainly for industrial platforms, ladders pedal, railings, channel floor, side road railway bridge, aerial tower platform, drain cover, covers, road barrier , parking lots, offices, schools, factories, enterprises, playgrounds, garden villas fence, also used as houses of exterior windows, balcony rails, highways, railways and railings. Grating as a new engineering material, mainly in the metallurgy, energy, marine, municipal, petrochemical, transportation, building materials, and other areas used as a platform for national defense, bridge, bridges, highway guardrail, trench cover, fences, gates and other facilities. At present, China's annual demand of about 270,000 tons of steel grating. Therefore, steel grating market prospects. Steel grating in all kinds of factories at home and abroad hundreds of dollars can be widely applied, such as power plants, chemical plants, oil refineries, steel mills, machinery factories, paper mills, cement, pharmaceutical, food processing plants. For a variety of ship's gangway, channels, pumping stations, the engine room platform. For a variety of bridges, such as the side of the road railway bridge, overpass, etc. Approach plank walkway. Used for oil extraction plant, car wash, aerial tower platform. Parking lots used for public works, large venues and building fences, road barriers, drainage covers road, ditch cover.
