Where steel reinforcement of a slab is required for structural reasons, the specification will more than likely require high-tensile steel bars as well as fabric mesh, and the design should be undertaken by a qualified engineer. Steel mesh comes in a wide array of profiles with varying mesh sizes and wire sizes as indicated in the table below.
The most commonly specified steel fabrics for paving works are A142 (6mm wires), A193 (7mm wires) and A252 (8mm wires). A142 mesh is often used in 100mm thick light-use slabs such as paths, driveways and garage bases, while A252 is normally associated with heavier-duty 150-200mm thick slabs, with A193 used in either. In light-use applications, a single layer of fabric may be used, but in heavier jobs, two layers are used "top and bottom".
There must always be a minimum of 50mm cover over steel reinforcement, both above, below and around . The fabric is supported from beneath at regular intervals by Hystools, Wire ring spacers, concrete bar spacers, Grade Plate Spacers which are purpose made for use with the sheets of Mesh fabric. . These spacers are placed roughly every 600mm or so, sufficient to carry the fabric without allowing it to sag unacceptably.
|Mesh Fabric||Sheet Size||Wire|
|A142 Mesh Fabric||2.4mt x 4.8mt||6mm|
|A193 Mesh Fabric||2.4mt x 4.8mt||7mm|
|A252 Mesh Fabric||2.4mt x 4.8mt||8mm|
|A393 Mesh Fabric||2.4mt x 4.8mt||10mm|
Bharat Wire Mesh offers reinforcing concrete mesh. We cooperate with wholesale and construction companies, owners of farms and suburban areas.
Welded mesh reinforcement bars are from 3 to 40 mm diameter, located in mutually perpendicular direction and forming a square or rectangular shape mesh. Reinforcing mesh opening size ranging from 50 mm to 250 mm. Distinguish heavy reinforcing mesh (diameter rods of 12 mm and above) and light meshes (the diameter of the rods from 3 mm to 12 mm).
When choosing a wire mesh, material, mesh sheet size, mesh opening, and the purpose must be taken into account. For example, if you need concrete mesh for plastering, the thin wire mesh is suitable.
Mesh reinforcement for the foundation, In the civil and industrial construction special attention and increased demands placed on the quality of the foundation, because it depends on the operational safety and durability of structures.
Masonry reinforcement mesh – the most popular type of wire mesh. It is referred to the building grid and used as a reinforcing element in the construction of reinforced concrete and masonry buildings. Masonry reinforcement mesh increases the strength of the structure and quality of plastering work. For the manufacture of masonry reinforcement wire mesh used steel wire diameter of 3 to 5 mm. The mesh size ranges from 50 mm to 250 mm.
Mesh reinforcement for the floor. This mesh is packaged in roll form. It is very convenient for delivery, because the diameter of the wire used is relatively small. The length of such a mesh size not more than two meters, which facilitates its transportation.
Reinforcement mesh used in road works to strengthen the road surface. This mesh is made from stainless steel with diameter of 3 mm, 4 mm, or 5 mm. Its composition with low carbon content allows qualitatively strengthen road terrain. The reinforcing road mesh is the most cost-effective option for construction and repair of roads, bridges, and large industrial plants. Usually, road mesh opening in sizes 50 × 50 mm, 100 × 100 mm, 125 × 125 mm, 150 × 150 mm. Its sheet sizes may be 1.5 × 2 m, 2 × 3 m, 2 × 6 m.
Trench mesh is long, narrow sheets of concrete reinforcing mesh, ideally sizes for trenches, paths or other narrow spaces. Its longitudinal wires (main wire) from 7.6 mm up to 15.6 mm diameter, and cross wire in 4 mm or 4.77 mm diameter. Trench rib mesh all comes 6.0 m length.
Brick wall reinforced mesh also named concrete slab mesh is a kind of welded wire mesh panel for reinforced concrete uses. It covers truss mesh reinforcement and ladder mesh reinforcement.
Mine mesh is a grid placed on the surface of the mine's walls. This mesh ensures the safety of the miners during drilling and it retains the walls against falling rocks. It is manufactured to exact specifications to meet the demands of the mining industry. Mine mesh offers protection to the miners from loose scaling in the mines. Flush cut edges improve handling, installation and maintenance of safety standards and these Welded steel mine mesh are available in a range of sizes and configurations to suit most individual mine requirements.
