Roads Drainage Grating

Steel bar grating is a widely used grating type. It can be used in the trench and drainage system as the trench and drainage cover to ensure the excellent drainage performance and secure the pedestrians safety. Like most of steel gratings, such as welded steel grating and press-locked grating, the drainage trench grating is made of carbon steel, aluminum steel and stainless steel. Different materials of grating can suit different applications of customers. Carbon steel grating is the most economical grating among the three types and the aluminum grating features lightweight and corrosion resistance, it can be used in the corrosive environments. The stainless steel grating has unique chemical stability, it is the ideal products to be used in the acid or alkali environments and keep a long service life. Drainage trench grating types A galvanized drainage trench grate with angle frame on the white background. Angle frame can increase the load capacity of drainage trench grate. Trench grate and angle frame It is the simplest and most economical types of types of trench covers. It can be installed on the trench and drainage to form a cover. This cover can not only ensure the excellent drainage performance, but allow the traffic passing through. The galvanized angle frame gives the maximum opening and supplies a strong and solid base for the grating. It can bear the load of steel grating can improve the load carrying capacity of grating. Except for the standard trench grate, there is a type of grate is made of close mesh steel grating. The close mesh steel grating is available for pedestrians wearing high-heel shoes, bicycles and other wheeled equipment easy passing through. Angle sided grates Angle sided grate is a type of drainage trench cover with angle bar on the two side of the grating. It is fit for the concrete trench, which is molded a channel to place the grates. The sided angle bars can bear the load capacity of the grating and ensure the long service life of the grate. The appropriate opening size can not only enable the drainage but also block the large wastes from entering the trench and blocking the trench. The angle sided grate has smooth and serrated surface for choice. And the common length of angle sided grates are 1m. A galvanized angle sided grate with smooth surface. Angle sided grate with smooth surface.A galvanized angle sided grate with serrated surface on the white background. Box grates Box grate is a type of drainage trench cover with galvanized frame. The frame make it easy to install the box grating onto ground. There are hinges connecting the grate and frame. This design is ideal for easy cleaning of trench. The surface of box grate can be smooth and serrated to suit different applications of customers. The grate on the frame is mostly welded steel grating which is the simplest and most widely used grating type.

Welded wire mesh Welded wire mesh, or welded wire fabric, or weld mesh is an electric fusion welded prefabricated joined grid consisting of a series of parallel longitudinal wires with accurate spacing welded to cross wires at the required spacing. Machines are used to produce the mesh with precise dimensional control. The product can result in considerable savings in time, labor and money. Uses of Welded Wire Mesh The welded wire mesh is a metal screen that is made up of low carbon steel wire or stainless steel wire. It is available in various sizes and shapes. It is widely used in agricultural, industrial, transportation, horticultural and food procuring sectors. It is also used in mines, gardening, machine protection and other decorations. Weld mesh is the term given to the kind of barrier fencing that is manufactured in square or rectangular mesh from steel wire, welded at each intersection. It is usually affixed to steel uprights. Weld mesh is a relatively cheap fencing solution but has the advantage over chain link wire of not bending so easily and not being so easily cut. It is therefore ideal where a low level of security is required but where chain link fencing is too easily overcome. Welded wire fabric (WWF) is also sometimes used in reinforced concrete, notably for slabs. Types of welded wire mesh There are several types of welded wire mesh which can be categorized according to their structure, use, and characteristics. Welded wire fabric (WWF) for concrete slab reinforcement This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards. The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2. The common sizes are in the following table: Electro galvanized welded wire mesh with square opening This type of welded wire mesh is designed for building fencing and in other infrastructural purposes. It is a corrosion resistant wire mesh that is largely used in structural building. It is also available in different forms like rolls and panels for industrial uses. Hot dipped galvanized welded mesh This type of mesh wire is generally made up of plain steel wire. At the time of processing it goes through a hot zinc covering process. This type of welded mesh ware with square opening is ideal for animal cage structuring, fabricating the wire boxes, grilling, partition making, grating purposes and machine protection fencing. PVC Coated Welded Mesh PVC coated welded mesh with plastic covering is constructed with galvanized iron wire of high quality. It has PVC powder covering that is processed by an automatic machine. The smooth plastic coating on this corrosion protective wire is attached with a strong adhesive which make increases durability of the wire. It is used in fencing residential and official properties like gardens, parks, building etc. The PVC coated welded mesh which is available as both rolls and panels, is also available in different colors like white, black, green etc. Welded Stainless Steel Mesh This kind of welded mesh wire is basically used in industrial fencing purposes. It is made up of stainless steel that has high strength and integrity. This corrosion resistance meshed wire is long lasting and is widely used in transportation, agricultural, mining, entertainment and other service sectors. Welded Wire Fencing Panels This is a type of meshed wire that is available as panels and is basically used for fencing purposes. It is available with or without galvanization. The non-galvanized version comes for a lower cost. Welded Steel Bar Gratings This type of welded mesh wire provides advantages like high strength, easy installation and feasible cost. It is mostly used for grating roads, making drainage coverings and building safety walls. It also has uses in chemical plantation, platform grating, metallurgy etc. PACKING:plastice paper outside,then in wooden pallet

Anping Tenglu Metal Wire Mesh Co.,LTD Welded Steel Bar Grating Welded steel bar grating is the most popular of all grating types due to its strength, cost-efficient production and ease of installation. Steel bar grating costs less time and labor in work. It saves about 50 to 70 percent work time compared with common binding wire mesh. The use of bar grating can also strengthen the concrete parts to reduce surface breaking ratio. Welded bar grating for reinforcement is especially suitable for big area concrete engineering. Using of welded bar reinforcement can save about 10 percent of the total cost of the project. It is also ideal for use as mezzanine decking since it supports the same loads as comparable solid flooring.More than that, its cost saving openness maximizes the circulation of air, light, heat, water and sound, while promoting cleanliness. And, where insurance codes permit, additional sprinklers can often be eliminated.Standard panels are available in widths of 2', 3' or 4'. Welded steel bar grating is resistance welded to create a rugged, one piece constructed panel. The bearing bars are automatically resistance welded at the contact point with the cross bars and, under a combination of high heat and pressure, are fused together to form a permanent joint.The cross bars provide a high degree of rigidity, yet retain a smooth flat surface for free and easy walking. Welded steel bar mesh panels have three types: black steel bar welded wire mesh, galvanized steel bar welded wire and hot dipped galvanized steel bar welded wire mesh. Welded steel bar panels are widely used in making of floors, ceilings, wall body, concrete road, bridge surface, airport, tunnel lining, concrete piping, etc. Specification: Wire Diameter: 5-16mm. Horizontal Spacing: 50.100.200.300.400mm. Vertical Spacing: 50-600mm. Panel length:1000-14000mm. Panel width:100-300cm
