Catwalk Heavy Duty Steel Grating Serrated Anti Corrosion Construction Galvanized
Galvanized Catwalk Serrated Anti Corrosion Heavy Duty Construction Steel Grating
vertically ,and at an equal pitch apart ,by welding with 200-ton hydraulic resistance automatic welding equipment ,then
cutting,punching and banding ends.
Loading bearing steel bar pitch:pitch between the two neighboring load bearing steel bars is 30mm,or40mm.
Cross bar pitch:pitch between two neighboring cross bars is usually 50mm or 100mm,Special specification ca be done according to
your request.
Welded steel grating:
when selecting a bar grating product, consider Welded Steel Grating first. Usually our most economical products, they provide a comfortable walking surface with nearly 80 percent open area. This, combined with the positive welded cross bar/bearing bar intersection, make these products our most popular. Manufactured from ASTM A-1011 carbon steel, welded gratings are recommended for nearly all industrial flooring applications.

Introduction of hot dip galvanized steel grating
Bearing bar
- A flat bar withstanding the main load is in consistent with the span direction .
bearing bar pitch
- the distance center to center of the two bearing bars.
Cross bar
- the connecting bars , made from twisted bar ,round bar or flat bar, which extend across the bearing bars
Cross bar pitch
- the distance center to center of the two adjacent cross bars.
Length
(span)- the maximum dimension of a grating panel ,measured parallel to the bearing bar ,and in the same direction as the bearing bars .
Width
- the maximum dimension of a grating panel ,perpandicular to the bearing bars .and in the same direction as the cross bars.
Width
- the maximum dimension of a grating panel ,perpandicular to the bearing bars .and in the same direction as the cross bars.
