Customized Low Carbon Galvanised Trench Grate , Drain Cover for
Drainage System
Description:
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.
They are widely used in steel structure platforms, stair treads,
sidewalks,drainages and well covers etc.
Feature:
Appearance: simple lines. Silver exterior, modern trends.
Best drainage: leakage area of 83.3%, more than double the cast
iron.
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.
We design and manufacture many kinds of steel gratings, they are
Plain Style Steel Grating, Serrated Style Steel Grating, I Bar Type
Steel Grating and other gratings. They are widely used in steel
structure platforms, stair treads, sidewalks, drainages and well
covers etc. We also supply standard steel grating and in customized
shapes per client's requirements.
