With Twisted Steel Trench Grate or Drain Cover for Airports, Parking lots, Roads, Railways
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
They are widely used in steel structure platforms, stair treads, sidewalks,drainages and well covers etc.
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.

1. Widely used in shipbuilding, harbor, oceanographic engineering, building, paper mills, cement plant, medicine, spinning and weaving.
2. Is applied in food stuff factory, transportation, municipal administration, parking lot , etc.
3. Also used by various plants such as electric power, petroleum,chemical industry.
Normally packed in pilling up ways with two pieces of square wood on both upperand bottom sides. there are four or six pieces of M10 long bolt pen trading the gratings and screwing together .it is suitable for loading and unloading by fork-lift and crane.
1. Strap Packaging: generally applicable to relatively neat grid of steel plate.
2. Pallet Packaging: Usually for export packing.
3. Screw Rod Fixation: using four screws bar through the steel grating aperture, with screw locking packaging methods.
(2) pressure welding
(4) welding of ends bar
(5) surface treatment
(6) final shipment
Tolerance of grating steel
The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm.
The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar.
Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not
