Professional Steel Grating Manufacturer
Generally, the manufacturing methods of steel grating are two types: pressure welding and press locking. The welding machine is made of high pressure resistance press welding machine. The manipulator automatically puts the bar on the flat steel, and welds the bar into the flat steel through powerful welding power and liquid pressure. So the high quality steel lattice plate with strong welding point, stability and high strength can be obtained. The horizontal steel bar is usually used to insert the flat steel. The groove is first laid on the flat steel, and then the cross bar is pressed into the slot to fix it.
Structural mode
The welded steel plate has good adhesion to the paint or galvanized layer because of the solder joint without slag. The T joint between the end grid plate and the load-bearing grid plate is connected by gas shielded welding. The grid plate is made of the flat steel as the longitudinal grille strip and the steel bar as a grid plate produced by the transverse joint. Steel members can be chosen as round steel, Fang Gang, torsion bar and so on. Compared with the inserted steel grid plate, the welded grid steel plate has the advantages of light weight and high transmittance under the condition that the load requirement is not very high.
We are one of the steel grating suppliers.Inserting steel grille plates is also a basic product for manufacturers. The warp and weft grille of this grille plate is generally the same specification of the flat steel strip or the height and width of the grille bar slightly smaller than the load grille. The difference between the products is mainly the distance between the horizontal and vertical grille bars, and the width and height of the grille bars have been changed. The transverse grid bar is embedded into the bearing grid plate and then welded by the pressure welding machine. As it is similar to the previous grid plate structure, the transverse bar is a strip, and its section coefficient is larger than the twisted square steel, so it has a higher bearing capacity than the previous grid plate. Because the horizontal and vertical grille share load together, it has the advantage of high carrying capacity per unit weight. Besides, it has the advantages of easy production, low cost, uniform form and so on.
Because the structural classification of steel grilles is different from the fixed methods of loading flat steel and cross bars. The cross section characteristics of the steel lattice, such as the radius of rotation of the cross section, the resistance to the moment of section, the moment of the section inertia moment, the load capacity and the stability, are different because of the difference in the size of the bar and the fixed method. The self weight of the steel grid plate under the same load is smaller. The energy consumption of the product process is low, the power consumption per ton of the welded grid steel plate is about 100kwh, and the electricity consumption of the grid steel plate is much lower.
Advantages and disadvantages
The manufacturing process of galvanized bar grating is relatively simple and the production efficiency is very high. It is necessary to choose suitable floral steel for the cross bar of steel sheet welding, which can be selected according to the needs. In this way, the maximum length reduces the weight of the steel lattice plate. The most important thing is to reduce the steel quantity and reduce the cost of the steel lattice plate. The cutting holes of steel grate are relatively simple and easy to operate, and edges are not easy to leave cutting marks. The disadvantage of pressure welded steel grate is that when welding the steel grating, we must pay attention to the direction of the flat steel and the direction of bearing capacity, only bearing the weight of flat steel. When welding the steel grid plate, we must consider the self internal force of the flat steel, that is, the direction of the flat steel, and then weld after rectification. If the direction is wrong, after welding or transportation, the steel grate will be deformed by internal force, which will seriously affect the exterior size of the steel grate, and some can not even be installed. In addition, the horizontal steel bar of the inserted steel plate is also made of flat steel, which is welded with the load bearing flat steel, and does not have the problem of deformation of the welded grid plate.
The inserted steel plate is more used on some machine equipment, it looks more solid, and the mutual locking makes it close tightly to each other in the case of pressure, and the deflection is very small. Walking to the top is like walking on the ground, very comfortable. The disadvantage is that there will be gaps between the bar and the flat steel, and it is impossible for each contact point to be welded. Therefore, the welding is not firm and the strength is reduced. The production cost is high, even the hot galvanizing treatment has high zinc content, because the direct gap is more, so the hot galvanizing cost is also very high.
Regardless of the type of steel grate, the reason why it appears, exists and develops so far lies in its practicality, followed by its economy. Unpractical and uneconomical varieties will be eliminated. Practical and economic products must have vitality.
