Drain cover is usually used in the side of the road and swage treatment plant, it is for water drainage.Trench Drain Cover Gratings are steel lattice panels formed with simple lines, secured with hinged lid and connection. Ideal replacement drainage covers for conventional cast iron materials. Suitable for light type and large span heavy loading environment. Widely used in sewage treatment system in urban roads, squares, gardens, docks, airports, parking lots, roads, railways, industrial engineering and other types of industrial buildings.

Trench cover is another usage of steel grating, it's usually used in drainage system, like sewage treatment plant, port drainage channels, and plaza drainage system. As our products are mostly hot dip galvanzied, it can resist corrision and rust. Moreover, we can produce different size of steel grating for customers according to different load capacity requirement, shape request, etc.

We produce three kinds of steel gratings, they are Plain Style Steel Grating, Serrated Style Steel Grating

and I Bar Type Steel Grating.

We can design and manufacture standard steel grating and in customized shapes per client's

requirements.

Hot-dip galvanizing: rust-proof and strong, maintenance and replacement.
Security design: box with hinged lid and connection, security, safe, easy to open.
Saving investment: large span. When overloaded, the lowest ratio of iron and saves replacement costs stolen, then crushed.
High strength: strength and toughness is much higher than cast iron, can be used for terminals, airports and other large span and heavy load environment.
Specifications and more: meet different environment and loading requirement. Span, the desired size and shape.
