Outdoor Metal Manhole Cover Grating 25*3 Circular Galvanised Grate
Outdoor Metal Circular Sewer Anti-Rust Grille Cover Plate Welded Steel Grating
Welded Steel Grating Introduction
Cooking plate cover is also known as "ditch cover", "shajing plate", "ditch cover plate", it USES the steel grid plate pressure welding and become, is simple in construction installation, light weight, good bearing and impact resistant capability is strong, good drainage, product surface after dealing with the hot galvanizing is beautiful, rustproof, has cast iron ditch cover plate incomparable advantages.
It is mainly used in some factories and high-grade residential areas, which is mainly because the cement trench cover is often crushed, and the road surface is damaged.
Therefore, the trench cover plate made of steel grid plate is suitable for different load loads.
Due to the ditch cover plate construction is simple, light weight, good bearing capacity, impact resistance, bending rather than breaking, large displacement, after hot dipping zinc treatment, beautiful and durable, anti-corrosion, with the advantages of cast iron cover plate incomparable.

1, usually we can according to the production of different materials, the trench cover plate is divided into hot dip zinc trench cover plate, stainless steel trench cover plate, spray trench cover plate, etc.
2. According to the shape of trench cover plate, it can be divided into: ordinary trench cover plate, U-shaped trench cover plate, tubular trench cover plate and open trench cover plate.
Welded Steel Grating Application:
The specific use of steel grating: aisle, ventilation, fences, mooring dock, trestle, the frame and frame, pedestrian overpass, drilling platform, transmission corridor bridge, bridge footpath, trench cover, ventilation window, railway across the aisle, manhole and lighting, anti-theft doors and Windows, airport fence, trash rack, wall fence, painting room (mainly automotive paint and furniture paint), storage shelves, equipment, sidewalks, billboards, livestock pens, equipment safety bar, pipe gallery landing pier, scaffolding, Marine pedal, washing, van, grating, shading box at the top of the aisle, platform, ladder pedals, Marine workboat, feeder walkway.
Welded Steel Grating Advantages:
1. Beautiful appearance: simple lines, silver appearance, modern trend.
2, the best drainage: water leakage area of 83.3%, more than twice as much as cast iron.
3, hot dip galvanizing: strong rust resistance, maintenance and replacement free.
4, anti-theft design: cover and frame with hinge connection, anti-theft, security, easy to open.
5, save investment: large span, heavy load, lower than cast iron price and save the cost of being stolen or crushed replacement.
6, high strength: strength and toughness is much higher than cast iron, can be used for wharves, airports and other large span and heavy load environment.
7, specifications: to meet the different environment, load, span, size and shape required.
The product has the advantages of simple construction, light weight, good bearing capacity, impact resistance, bending rather than folding, large displacement, beautiful and durable after hot dipping zinc treatment, anti-corrosion, and has the advantages of cast iron cover plate.
It adopts hinge connection or hook connection, which is easy to open and has anti-theft function.
Welded Steel Grating Process:
The process design of steel grid plate is to arrange the material according to the geometrical information of the sheet according to the size of the original plate, and the ultimate goal is to make the material cutting plan take into account the maximum utilization rate of the material and higher production efficiency.
Welded Steel Grating installation:
The connection mode of steel grid plate is fixed and installed with buckle connector, which is composed of three parts.
