Steel grating is flat steel bar according to a certain distance and cross
arranged and welded into the middle of a square lattice with an
iron and steel products ,steel grating generally use carbon steel
production,appearance of hot dip galvanized,can serve to prevent
the role of oxidation,can also be made of stainless steel .
Welded Steel Bar Grating is made by Carbon or mild steel of certain sizes through the
processing of grooving, lock-pressure, welding, finishing and other
treatment.Welded Steel Bar Grating can be actually made from copper, aluminum and other materials,
while gWelded Steel Bar Grating is the mostly used one due to its economic cost and good property.
Welded Steel Bar GratingApplication:

Welded Steel Bar Grating Features:
Aesthetic outlook: Simple lines and silver appearance meeting the modern trend.
The best drainage: Leakage area of 83.3 percent, more than twice of cast iron products.
Hot-DIP galvanized treatment: Good rust-proof property, maintenance-free replacement.
Anti-theft design: The cover and the frame is joint with hinge offering security, safety and open convenience.
Savings investments: Large-span. Less lost for heavy load compared with cast iron products. Cost can be saved for the risk of being stolen or crushing one if cast iron is uses.
High strength: The strength and the toughness are much higher than cast iron. Can be used for terminals, airport and other large-span and heavy loading condition.
Specifications: More specifications and sizes optional for meeting various environment, load, span, sizes and shapes.

General information of 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
baering bars .
Width - the maximum dimension of a grating panel ,perpandicular to the
bearing bars .and in the same direction as the cross bars.
