JH Steel Grating is manufactured through precision welding of flat steel and cross/round bars at specific intervals. Our steel grating products feature high strength, lightweight construction, excellent load-bearing capacity, and easy installation. The hot-dipped zinc coating provides superior corrosion resistance.
Material: High quality low carbon steel
Types: Serrated and plain
Finishes: Electro galvanized, hot dipped galvanized (various surface treatment options available)
