Type A: It consists of an upper press plate with double hooks, A lower press plate with teeth and an M8 inner hexagon bolt.
 

Type B: consists of an upper pressure plate with a double hook (one hook can enclose two adjacent steel grids together), a lower pressure plate with teeth and an internal Angle bolt of >M8.
 

Type C: consists of an upper pressure plate with a double hook and an M8 hex head bolt that can be welded to the support member.

 

Steel grating fixing method: Two methods can be used to use welding and Steel Installation Clip to tighten.The advantage of welding is permanent fixed, not loose;The advantages of the mounting clip are that it does not destroy the hot dip zinc layer and is easy to disassemble.The safest method is not to clamp down, directly screw head welding on the beam, to ensure that the steel lattice plate will not fall from the beam because of the installation of loose clip.
 

Welding fixation is suitable for permanent parts that do not need to be disassembled, such as the platform around the equipment, and the installation clip has the characteristics of not destroying the zinc layer and easy disassembly.Mounting clamps are suitable for various series of steel latticed plates, including upper clamps, lower clamps and M8 or M10 inner hexagon socket cylinder head bolts.The method of welding fixation is: on the first flat steel of each corner

1. Directly weld the steel grid plate or step plate on the supporting steel structure, and brush the welding place with zinc silver powder paint twice.

2, the use of the Yangtze River Delta steel grid special installation clip installation, do not destroy the galvanized layer, easy to disassemble.Each set of mounting clamps includes an upper clamp, a lower clamp, an M8 round head bolt and a nut.

3. Stainless steel mounting clip or bolt connection and other fastening methods can be provided as required.

4, the steel grid installation clearance is generally 10MM.

5, the installation must pay attention to the installation is firm and reliable, should often check, prevent the installation clip loose fall off, close to the vibration source of the steel grid plate welding or add rubber pad.
