A36 S275 Q235 Galvanized Compound Steel Grating for Petroleum Environmental Projects
Description:
Composite steel grid grating is composed by 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 3mm, 4mm, 5mm or 6mm.
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.
Compound Steel Grating is composed of a span bearing capacity of the steel frame and the sealing surface of the pattern plate of a product.In the steel grid plate side or bottom weld steel net made of complex network, can prevent small drop, in the barn, restaurant, warehouse can prevent the mice or other animals.

1.We can provide free steel bar grating samples of small sizes, but customers need to pay the express cost.(This can be discussed)
2.OEM is accepted. We have technical engineers. Then we can design steel bar grating for customers’
projects, and make
products according to customers’ drawing.
3.Once receiving customers’ inquiries. Our company promises to provide services within 24 hours.
Installation Method:
- Directly weld the steel grating plate or footboard in the support steel structure, and the welding place brushes zinc powder paint.
- Uses special-purpose steel grating installment clamp, which does not destroy galvanization level, disassembles and assembles conveniently. Each set of installation clamp includes up-clamp, down-clamp, head bolt and nut.
- According to the need, provide stainless steel installment clamp or bold jointing and so on tight method.
- Generally the gap between steel grating plate is 100mm.
- The steel grating plate which approaches the vibration should weld or add rubber packing.
