LTA PUB HDB DIC Trench Grate or Drain Cover for the Building and
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.
And ,we can provide the LTA PUB HDB DIC Trench Grate or Drain Cover for the Buiding and
Appearance: simple lines. Silver exterior, modern trends.
Best drainage: leakage area of 83.3%, more than double the cast
Hot-dip galvanizing: rust-proof and strong, maintenance and
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.
