Steel grating types are: galvanized steel grating, steel grating plug, composite steel grating, pressure welding steel grating, serrated steel grating, special steel grating, steel grating dense marine steel grating, stair treads, flat steel grating, steel grating word, heavy duty steel grating. Steel grating steel grating another name called. ????? Flat steel grating is carried out in accordance with a certain distance and cross rails arranged and welded into the middle of an iron and steel products with a square lattice, mainly used for drain cover, steel platform boards, ladders stepping board. After twisted rails commonly used square steel. ????? Steel grating commonly used carbon steel, galvanized exterior, can play a role in preventing oxidation. Can also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof properties. Production standards ????? steel grating, and China for YB / T4001-1998; in addition the United States, Britain, Australia and New Zealand also have their own standards. Steel accordance with the standards GB700-88, GB1220-92. ? ????? Steel grating tooth surface can be washed to increase slip resistance. I can also be used in flat-type flat steel production. ????? Steel grating production methods: There are two kinds of machines and hand pressure welding production. High pressure resistance pressure welding machine pressure welder, robot automatically on flat horizontal crossbars evenly through strong welding power and hydraulic pressure into the flat rail bonding, which can be sturdy joints, high stability and strength of high-quality steel grating. Handmade steel grating is the first punch in the flat, and then into the hole in the rail welding, rail and flat there will be a gap, but not every contact point for welding, soldering and therefore no firm , the intensity decreased. Platform petrochemical, municipal engineering, port engineering, mechanical industry, power plants water plants, iron and steel industry, manufacturing, food processing, sewage treatment plants, municipal engineering, environmental engineering and other fields: steel grating use ????? , walkway, bridge, ditch cover, covers, ladders, fences, guard rails, and many other industries have been widely used. ????? Steel grating characteristics: ????? 1. High strength, light structure: strong pressure welding grid structure with high carrying it, light structure ????? 2. Ease of loading and other characteristics ????? 3. Appearance, durable: hot-dip zinc surface treatment it has a very good corrosion resistance ????? 4. 5 ????? surface gloss appearance. Ventilation, good lighting, cooling, explosion-proof, non-slip performance; against product contamination. ????? ????? Steel grating product specifications 1. Bar Pitch: 30-60 (mm); ????? 2. Bar spacing: 50-100 (mm); ????? 3. Width: 20-60 (mm); ????? 4. Thickness: 3-50 (mm). Plug Grating Description: steel grating on the plug (also known as pressure lock steel grating), is composed of a certain size plain carbon flat steel, stainless steel, brass plate, aluminum plate slotted (hole), plug the pressure lock, welding, finishing and other processes made of products. ????? Plug grating characteristics: it contains an overview of pressure welding steel grating, high strength, corrosion, maintenance-free characteristics, and unique combination of homogeneous precision, lightweight fine structure, natural harmony, style and elegant features. ????? Plug grating Uses: Widely used in municipal engineering civil and commercial buildings, theaters, metro, suburban railway and so on, can be used to insert steel grating ceiling, indoor and outdoor decoration decoration, platform aisle, louvres ( Wells), advertising plaque, a variety of cover and so on. Galvanized steel grating galvanized steel grating is also known as galvanized grating, galvanized grating is made of flat steel and bars with certain distances, welded on the high pressure resistance welding machine the original board, after cutting, incision, opening, edging and other processes of deep processing of finished products to customer requirements. ????? Category: galvanized grating fabrication process considered by pressure welding galvanized steel grating and pressure lock galvanized steel grating; galvanized grating surface according to the shape of the tooth into Redu zinc grating, galvanized grating plane type, I type galvanized grating and composite galvanized grating. Characteristics: high strength, light structure: strong pressure welding grid structure with high carrying it, the structure of light, easy loading and other characteristics; appearance and durability. ????? Uses: Widely used platform petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, environmental engineering and other fields, walkway, bridge, ditch cover, covers, ladders, fences, railings. Serrated steel grating serrated steel grating from one side is serrated flat welded together, in addition to ordinary steel grating characteristics and uses also has a strong anti-slip capability, especially for wet, slippery places, Offshore platform. ????? Serrated steel grating hot-dip galvanized surface treatment, has a strong anti-rust power. ????? Serrated steel grating can be used as a drain cover and frame hinge connection, security, safety, easy to open. ????? Serrated steel grating made of high strength steel, the steel grating with high strength: the strength and toughness is much higher than cast iron, can be used for docks, airports and other large span and heavy load conditions. This product has a large mesh with the best drainage: leakage area of ??83.3%, more than twice the iron. Product appearance: simple lines, silver exterior, modern ideas, saving investment material Province: large span, heavy load, low prices than cast iron; and save iron Gein stolen or crushed and replacement costs.
