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.
high strength, light structure with firm grids pressure welded structure and high bearing property, easy suspending installation, beautiful appearance ,durability with hot galvanized finish, good anti-corrosive property, and bright surface, good ventilation, lighting. cooling and anti-explosion. and deposit-proof.
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.
