Precautions for design and production of steel grating panels

Hot dip galvanization of steel grating lattice plate is to immerse the steel grating lattice plate components after surface purification into 460-469 degrees of melted zinc liquid,

so that the steel lattice plate components are coated with zinc layer, the thickness of which is not less than 65μm for 5mm thin plate and not less than 86μm for thick plate.

This protection method of steel lattice plate has good corrosion resistance and long service life. And there is no maintenance and other advantages.

So what are the key points that hot dip galvanized steel plate planners and producers should pay attention to?

Generally, there are the following points.

Hot-dip galvanized steel grating lattice planners and producers should pay attention to the following key:

1: On the appearance of material treatment, the first process of hot dip zinc is pickling rust removal, and then cleaning. These two processes are not complete will give corrosion foam left hidden trouble

2: The steel plate to be welded must pay attention to the cleaning process of galvanized acid from the unwelded part to the internal immersion,

but also need to clean up the spatter occurred during welding. Other to avoid the occurrence of difficult to clean up the welding slag, coated with splashes attached to avoid agent, and then in the welding.

3: steel plate shape is complex, easy to cause deformation and damage, should be galvanized respectively.

4: Because the steel plate is attached to the surface of impurities, it is necessary to be treated before galvanizing. The shape of the steel lattice plate planned by colleagues needs to be uniform in thickness

5: steel plate planners need to consider the change of mechanical strength before and after galvanizing and the reprocessing of steel plate after galvanizing.
