steel, aluminum, and galvanized steel. Among them, the galvanized
steel grating is the most cost effective and economical type with
long service life and high load bearing stength. And it is the most
widely used in industrial, commercial and residential projects.
Welded galvanized grating. The cross bars are welded onto bearing
bars with the high pressure resistance welding machine and then
cutting, banding, surface treatment.
Press-locked galvanized grating. The cross bars are pressure locked
onto the bearing bars with grooving and then welding and hot dipped
galvanizing.

Product Description
Steel Grating Drainage Trench Cover and Well Cover
Steel bar grating is a good choice for strength, safety, long-term
cost and durability.
Bar Grating consists of a series of bearing bars, welded (or
otherwise joined) at various intervals to
perpendicular cross bars to form a load-bearing panel. It is
available in a wide selection of panel sizes.
Stair treads are the horizontal sections of stairs that serve as
the step surface of each step.
These treads are installed on the top of each step.

Application
Steel grating regularly appears on catwalk, factory floor,
platform, railing infill panel, stair tread, foot pedal,
drain cover, commercial and industrial flooring.
Technology
Welded galvanized grating. The cross bars are welded onto bearing
bars with the high pressure resistance welding machine and then
cutting, banding, surface treatment.
Press-locked galvanized grating. The cross bars are pressure locked
onto the bearing bars with grooving and then welding and hot dipped
galvanizing.
Features & Characteristics
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.
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.
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.
Applications
Galvanized grating are designed and manufactured for various
industrial and civil constructions in city road, gardens, yard,
airport, railway and industrial engineering.
Hot dip galvanized steel grating is the best choice for steel
platforms in airports. Grating with 30 × 3 mm thick load bearing
bars with a pitch of 30 mm and traverse bars at 50 mm or 100 mm is
the suitable one.
