Grating Trench Cover, also known as rainwater grate or drain cover, Trench Drain Cover is carefully made of high-quality materials, with a simple yet refined appearance, which can be perfectly integrated into various environmental scenes. From city streets to commercial parks, from residential areas to industrial plants, its versatile style not only ensures drainage function, but also adds a sense of neatness and order to the ground. Each cover is processed with fine craftsmanship, and the edges and corners are rounded and smooth, eliminating safety hazards and escorting pedestrians and vehicles.
Technical Parameters
1. Load-bearing capacity: According to different specifications and materials, the load-bearing range can reach 1-100 tons , which can easily cope with the frequent rolling of daily pedestrians, small vehicles and even heavy trucks, ensuring stability without collapse. For example, the cover plate selected for conventional sidewalk areas can withstand at least 5 tons of pressure; while in heavy-load areas such as logistics parks and ports, the Heavy Duty Trench Cover Plate can bear 50 tons of pressure, which is solid and reliable.
2. Material characteristics: A variety of material options are available, such as corrosion-resistant stainless steel or hot-dip galvanized carbon steel, which can serve for a long time in humid, acidic and alkaline environments with a lifespan of over 20 years; high-strength ductile iron material, which has both toughness and wear resistance to resist daily wear and impact; and lightweight and environmentally friendly fiberglass composite materials, which are easy to install and recyclable, in line with modern sustainable development concepts.
3. Size: A wide variety of sizes, including bearing bars with non-slip serrated surfaces, widths from 10cm to 100cm, and lengths from 30cm - 300cm. Customizable on demand, precisely adapted to various gutter sizes, whether it is a narrow indoor gutter or a wide municipal drain, our design team can find the perfect match for you .
4. Style selection: Special styles can be customized, such as flip-up manhole covers for easy maintenance.
Trench cover load level:
| Load Class | Vehicle Full Laden (Kg) | Back Singlo-wheel Load(KN) | Wheel-oressure Area aXb() mm |
| T-25 | 25,000 | 100 | 200x500 |
| T-20 | 20,000 | 80 | 200x500 |
| T-14 | 14,000 | 56 | 200x500 |
| T-6 | 6,000 | twenty four | 200x240 |
| T-2 | 2,000 | 8 | 200x160 |
GT type trench cover:
GT type trench cover is suitable for roads other than highways, where the traffic volume is generally not large. When used as a cross-sectional trench cover, the danger of the cover jumping up should be considered and bolts should be used for fixing. It is suitable for trenches with support edges (T-shaped trenches), and the edges are usually protected by angle steel.

GU type trench cover:
For ordinary concrete-built trenches without edges, the use of U-shaped trench covers is very simple and economical, and no special trench edges are required. When the load is T-6 or T-14, it is recommended to bury angle steel at the upper edge of the trench. At the same time, prefabricated U-shaped trench blocks can also be used to build the trench to effectively prevent sewage from leaking to the ground. When vehicles need to pass, GU-type trench covers are only suitable for side trenches.

GM type manhole cover:
GM type well hole steel grating cover can be used for the covers of rainwater wells, sedimentation wells, sewer wells, sewage wells and other water supply and drainage wells or air holes and manholes in municipal facilities such as roads and parks. GM type well hole steel grating can be designed into a coverable style, and the opening and closing angle that can be flipped up is usually 110°. The steel grating cover with hinge pins is not only anti-theft but also simplifies the construction procedure.

Application Fields
Municipal Engineering
A large amount of rainwater needs to be drained away quickly in urban roads, bridges, squares, etc. Trench Cover Grating is a key link. It effectively prevents debris from clogging the drainage system, ensuring that there is no water on the road surface during rainy days and smooth travel.
Commercial areas
Around shopping malls, hotels, and office buildings, there is frequent flow of people and logistics, so the high strength and aesthetics of the cover are particularly important. It not only bears the heavy pressure of vehicle parking and cargo handling, but also maintains the commercial image with a neat appearance.
Industrial sites
Factory workshops, warehouses, and logistics parks often have chemical leaks and heavy machinery running. Corrosion-resistant, high-load-bearing covers can cope with complex working conditions, ensuring continuous and efficient drainage and unaffected production operations.
Residential community
In residential areas, drainage is ensured while safety is emphasized. The anti-slip design of the cover prevents pedestrians from slipping.
