Composite steel grid grating is composed of steel grid grating of certain load-bearing and checkered plates.
This kind of bar gratings may deform going through the hot dipped zinc coating process. So heavy type steel bar with big gauge is normally chosen in making composite steel grid gratings.
The checkered plates are normally in the thickness of 3 mm, 4 mm, 5 mm, or 6 mm.
composite lattice steel plate by hot-dip zinc processing, it will be due to thermal stress generated warpage, in particular the use of larger models steel grid plate, school-more difficult, please note that selection.
Jiangsu Shengho steel material Co.,Ltd is a leading professional manufacturer of steel grating, stair treads, handrails, trench grating, grating clips, cable trays in China.
