Industrial Suspended Working Platform , Load Bearing Platform Pack
Installation
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 Welded Steel Bar Grating is the mostly used one due to its economic cost and good property.
Welded Steel Bar Grating Application:
Welded Steel Bar Grating, with robust design and spanning abilities, is very strong and
safe for the support of floors and elevated walkway. It can be used
for ceiling, interior decoration, decoration, platform aisle,
ventilation windows, (Wells), advertising plaque and other
construction.
Simple lines and silver appearance meeting the modern trend.
Leakage area of 83.3 percent, more than twice of cast iron
products.
Hot-DIP galvanized treatment: Good rust-proof property,
maintenance-free replacement.
The cover and the frame is joint with hinge offering security,
safety and open convenience.
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.
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.
