The mesh grid is also known as a steel grid plate. The mesh grid is cross-arranged with flat steel at a certain distance and crossbars (twisted square steel, square steel, round steel, flat steel, etc.), and welded into a square A kind of steel products made of lattices. Steel gratings are mainly used to make gutter covers, steel structure platform plates, and steel ladder steps. The crossbar is generally twisted square steel. Steel gratings are generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. Can also be made of stainless steel. The steel grating has the properties of ventilation, lighting, heat dissipation, anti-skid and explosion-proof.
Stainless steel mesh grille
The stainless steel mesh grid can be divided into plane type, tooth type, and I type, with more than 200 specifications and varieties (according to different use environments, the surface can be treated with different protection).
There are two methods for making stainless steel mesh grids: machine pressure welding and hand-made: machine pressure welding uses a high-voltage resistance pressure welding machine, and the robot automatically places the horizontal bar on the evenly arranged flat steel. The powerful welding power and hydraulic pressure will The cross bar is pressure welded into the flat steel to obtain a high-quality steel grid plate with strong solder joints, high stability and strength. The hand-made steel grid plate is first punched in the flat steel, and then the cross bar is placed Spot welding in the hole, there will be a gap between the cross bar and the flat steel, but each contact point can be welded to achieve the equivalent melting connection of the flat steel and twisted steel, so the welding will be stronger and the strength will be improved, but the appearance is not as good The beauty of pressure welding!

Composite mesh grille
The composite mesh grid is a product composed of a steel grid plate with a certain spanning ability and a checkered plate on the sealing surface. It can be composed of any type of steel grid plate and different thickness of industrialized steel plates. But the most commonly used steel grid plate is G323 / 40/100 as the low plate; the pattern steel plate is usually 3mm thick plate, and 4mm, 5mm or 6mm plate can also be used.
How to fix the mesh grid
Two methods are available: welding and mounting clips. The advantage of welding is that it is permanently fixed and will not be loosened. The specific position is on the first flat steel at each corner of the steel grid plate. The weld seam is not less than 20mm in length and 3mm in height. The advantages of the mounting clips are the destruction of the hot-dip zinc layer and the ease of disassembly. Each plate requires at least 4 sets of mounting clips, and the number of mounting clips used increases with the length of the plate. The safest method is to directly weld the screw head to the beam without lowering the clamp, to ensure that the steel grating does not slip off the beam due to the loosening of the installation clamp.
The plug-in steel grid plate is made of common carbon flat steel, stainless steel, brass plate, and aluminum plate of a certain size through slotting (hole), plugging, welding, finishing and other processes. It has many advantages such as light weight, high strength, anti-corrosion, maintenance-free, and beautiful. It is widely used in civil and commercial buildings, theaters, subways, urban railways and other municipal engineering fields. It can be used for ceilings, interior and exterior decoration, platform walkways, ventilation windows (well ), Advertising plaques, various covers, etc.
