Galvanized steel grating:A36 is the common grade. After welding is completed, surface treatment will be carried out: mild steel grating will be hot-dip galvanized or painted to make it look beautiful or corrosion-resistant.
Stainless steel grating:Common grade is SS201, 304, 316, 316L. Stainless steel grating itself has a strong corrosion resistance, suitable for food processing and chemical fields.
I Bar Steel Grating:With its unique I-section design, it exhibits excellent bearing capacity and stability, and is suitable for heavy-loaded industrial platforms, bridges and other places, and has both ventilation and light transmission properties.
Bar grating types are specified by bearing bar spacing followed by cross rod spacing.
