With Angle Frame and Panel Trench Grate or Drain Cover for the Parking Lots, Roads
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.
Angle steel overlock series products, mainly used for hotel kitchen trench, ratproof, easy to clean. Marble ground, do not destroy the original ground, laid simply. Used in Top Stairs, the grid is small, BuKa heels. This drain cover no need prepare beforehand, when installation,put the cover directly on the two sides of the edge, simple and convenient. This kind of steel trench cover generally the bearing bar pitch is small, usually by 15 mm, 20 mm, 25 mm and 30 mm ,Cross bar pitch usually by the 30 mm, 50 mm or 100 mm. Because the area is no need much bearing capacity, using the steel flat is general lesser, commonly used steel specification is: 20 * 3, 25 * 3, 30 * 3, 32 * 3, 35 * 3, 40 * 3, 30 * 4, 40 * 4, 25 * 5,30 * 5 , 32 * 5, 35 * 5, 40 * 5, 50 * 5. Use our advanced steel grating pressure resistance welding equipment welding, cutting, overlock, galvanized etc.the processing to finish. Also can use pressure locked steel grating to make.
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.

WELDED GRATINGEconomical design ideal for most industrial applications. Manufactured by welding the bearing bar/cross bar intersection, typically with automated forge welding equipment. Available in carbon steel and stainless steel.
DOVETAIL PRESSURE LOCKEDPopular for the manufacture of aluminum, stainless steel, and close mesh gratings. Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically deformed to lock the bars in place.
SWAGED PRESSURE LOCKEDAssembled by inserting pre-punched bearing and cross bars into an “eggcrate” configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications.
RIVETED GRATINGExceptionally durable grating manufactured by riveting bearing bars and bent connecting bars at their contact points. Excellent for applications involving impact loads and repetitive traffic patterns.
