Definition of welding steel gratingWelding steel grating is beautiful and practical, and can meet the load requirements under different conditions, making it better than other products with the same purpose. In recent years, they have been more and more widely used. Loaded flat steel and crossbars (twisted square steel, square steel, round steel, flat steel, etc.) are arranged at a certain interval of warp and weft, and welded on a high-voltage resistance welder to form the original plate, which is cut, cut, cut, and hemmed And other processes are processed into finished products required by customers. Welded Heavy Duty Gratings are designed to service applications subject to heavy rolling and static loads such as plant floors,highways, loading docks, inlet covers, and airports. Since conditions can range from smaller forklift to large truck or aircraft traffic, heavy duty gratings are manufactured in a wide range of bar sizes and spacing.Types of welding steel gratingAccording to the surface shape, they are divided into tooth-shaped welding steel grating, flat welding steel grating, type I welding steel grating, and composite welding steel grating. According to the surface treatment, welding steel grating plate can be divided into hot-dip galvanized welding steel grating plate, spray-painted welding steel grating plate, and original welding steel grating plate.Features of welding steel grating1.Beautiful appearance: simple lines, silver appearance, modern trend.2.Best drainage: more than twice as much as cast iron rafters.3.Hot-dip galvanized: strong anti-rust, maintenance-free and replacement.4.Anti-theft design: The cover and frame are hinged, which is anti-theft, safe and easy to open.5.Save investment: Under heavy-span heavy load, it is cheaper than cast iron and saves the cost of crushing and replacing if stolen.6.High strength: Its strength and toughness are much higher than those of cast iron. It can be used in large span and heavy load environments such as terminals and airports.7.Many specifications: meet the needs of different environments, loads, spans, sizes and shapes.Difference between manual welding and machine weldingManual welding: The hand-made steel grid is punched in flat steel first, and then the cross bar is spot-welded into the hole. There will be a gap between the cross bar and the flat steel, but each contact point can be welded to achieve flat The equivalent melting connection of steel and twisted steel, so the welding will be stronger and the strength will be improved, but the appearance is not as beautiful as the machine welding!Machine welding: The machine pressure welding uses a high-voltage resistance pressure welding machine. The manipulator automatically places the crossbar on the flat steel bars that are evenly arranged. The crossbar is pressed into the flat steel bar by powerful electric welding power and hydraulic pressure. The point is strong, but the machine welding is not as strong as manual welding, easy to open welding, but the appearance is beautiful.
Introduction About Steel GratingA steel grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated). When the two sets are perpendicular, this is also known as a grid (as in grid paper) or a mesh. Steel grates are also functional for industrial decks and flooring in chemical plants, food processing facilities, and oil and gas refineries. Metal grates are ideal for these applications, since they allow liquid to pass through the material, which helps to prevent slippery and hazardous work conditions. In addition, pedestrians rely on metal grates in public walkways, and near fountains and trees.Advantages of Steel Grating:1.Material saving: the way to minimize material saving under the same load condition, 2.Correspondingly, the material of supporting structure can be reduced.3.Reduce investment: save material, labor, construction period, no cleaning and maintenance.Construction is simple: on the preinstalled support with bolt clamping or welding fixed, one person can be completed.4.Time limit saving: no need to reprocess the product on site, the installation is very fast.Durability: it has been treated with hot dip zinc anticorrosion before delivery, strong impact and weight resistance.5.Modern style: beautiful appearance, standard design, ventilation and light, give a person with the overall smooth modern feeling.Light structure: less material, light structure, and easy to hoist.6.Reduce wind resistance: due to good ventilation, when the wind resistance is small, reduce wind damage.7.Dirt proof: no rain, snow and dust.8.Ventilation, lighting, heat dissipation, explosion - proof, anti - slip performanceFind The Best Steeling Grating HereTianjin Shunjinhua Machinery Manufacturing Co.

Building steel grating has remarkable green building characteristics and is a representative project of building energy saving. The advantages of building steel grating are good seismic performance, domestic demand driven by building steel and high degree of industrialization of building steel grating, which is conducive to promoting the technological progress of construction industry. What are the characteristics and applications of building steel grillage? 1. The shape of steel grating is beautiful and durable. It has good anti-corrosion ability and beautiful surface after hot-dipped zinc surface treatment. Steel lattice plate has many advantages, such as light weight, high strength, large carrying capacity, anti-skid safety, easy cleaning, durable and so on. 2. The steel lattice plate is welded into a steel product with square lattice in the middle. The steel lattice plate is arranged crosswise with flat steel according to certain spacing and cross bar. Mainly used for ditch cover plate, steel structure platform plate, steel ladder pedal, etc. The cross bar is usually made of square steel which has been twisted. Hot-dip galvanized steel gratings are usually made of carbon steel in order to prevent oxidation. It can also be made of stainless steel. 3. There are two kinds of welding of steel grating: press welding and manual manufacture. The machine press welding uses high voltage resistance press welding machine. The manipulator automatically places the horizontal bar in the uniform arrangement of flat steel. Through strong welding power and hydraulic pressure, the horizontal bar is pressed into the flat steel, so that the solder joint is stable and strong. Hand-made steel grating is first punched on flat steel, then the cross bar is put into the hole for spot welding. There will be a gap between the cross bar and flat steel, but each contact point can be welded, so the strength could be increased.
