1) Product name: Galvanized steel grating, also known as hot-dip galvanized steel grating. Galvanized steel grating after being produced, usually on the first item for anti-corrosion treatment. In the production process is usually divided into hot-dip galvanized and electro-galvanized two kinds of galvanized steel grating. Hot dip galvanized steel grating production process is made of flat steel and bars with certain distances, high pressure resistance welding machine welded together on the original board, after cutting, incision, opening, edging and other processes of deep processing customers requirements for the finished product, and then after hot galvanized. 2) hot dip galvanized steel grating classification: 1. Should be classified according to the manufacturing process are: pressure welding galvanized steel grating and pressure lock galvanized steel grating are two types; 2. Should the press hot-dip galvanized steel grating surface shape classification may include: hot dip galvanized steel grating toothed, flat hot-dip galvanized steel grating, I hot-dip galvanized steel and hot dip galvanized composite grating four types. 3) identification method Description: Steel Grating models, depending on the load flat steel specifications, shape, spacing load flat steel and rail combination, as well as surface treatment, such as different state, forming a variety of specifications, code-named: (1) hot dip galvanized Grating flat center spacing: According to distinguish between series: Series 1 30mm; Series 2 is 40mm; Series 3 to 60mm. (2) hot dip galvanized steel grating rail center spacing: Series 1 100mm, Series 2 is 50mm .. Other specifications can be customized. (3) hot-dip galvanized steel grating steel: Q235A or made of stainless steel, has a common plane type, tooth type and section I slip type. Common specifications 20 * 5,25 * 5,25 * 3,32 * 5,32 * 5,40 * 5,40 * 3,50 * 5,65 * 5,75 * 6,100 * 8,100 * 10 and so on. (4) hot-dip galvanized steel grating crossbar: Material for Q235A or 304 stainless steel round bar, twisted steel, square steel or six angles. Twisted square steel plate garden by the side of the mold by drawing and twisted together, their common specifications are 5 * 5,6 * 6,8 * 8mm and so on. 4) hot dip galvanized steel grating characteristics: 1. High-strength lightweight structure, the use of strong bonding grid structure, which makes galvanized steel grating with a carrying capacity of high-strength and lightweight structure. 2. beautiful appearance, durability, after hot-dip zinc surface treatment it has a very good corrosion resistance, while maintaining the surface gloss appearance. 3. Good ventilation, lighting, cooling, explosion-proof and anti-slip properties, etc., and to maintain a certain performance against product contamination. 5) hot dip galvanized steel grating uses: widely used in petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, environmental engineering and other fields, which are often used to make a platform, walkway, bridge, ditch cover, covers , ladders, fences, railings.
