What are the Factors for the Quality Assurance of the Reinforcement Mesh?

Rebar Mesh is using a special welding machine to weld the same or different diameters of longitudinal and transverse steel bars, and resistance spot welding (low voltage, high current, welding contact time is very short) to weld the formed mesh steel bar products. The longitudinal reinforcing bars and transverse reinforcing bars are arranged at a certain distance and at right angles to each other, and all intersections are welded together by resistance spot welding.

The welding procedure of the reinforcement mesh is automatically controlled and produced by the computer, and the welding quality is good, and the mechanical properties of the reinforcement bar are almost unchanged before and after welding. Reinforced mesh is a new type of building material with high efficiency, energy saving and reinforced concrete structure, which is widely used in the beams and columns, floor slabs, roofs, walls, concrete pavements and bridge decks of industrial and civil buildings.

Advantages of reinforced mesh:

1. Significantly improve the quality of reinforcing steel engineering: Compared with the traditional manual banding of reinforcing steel, the welded wire mesh has greater rigidity of the mesh, better elasticity and uniform spacing. The reinforcing steel is not easy to be locally bent when pouring concrete, and the thickness of the concrete protective layer is easy to control and uniform In the bridge deck pavement, the qualified rate of the measured protective layer of the welded mesh is above 95%.

2. Significantly improved construction speed: A large number of construction practices at home and abroad have shown that the use of Steel Rebar Welded Mesh has greatly reduced the number of on-site installation man-hours and eliminated the need for steel processing sites. In the case of the same amount of reinforcing steel, it takes about 4 man hours for a 1000kg welded mesh to be laid in a single layer, 6 more man hours for a double layer net, and 22 man hours for second hand lashing, which can save labor compared with manual lashing 50% ~ 70%.

3. Enhancing the crack resistance of concrete: The crossing point of artificial steel wire binding is easy to slide, the grip strength of steel and concrete is weak, and cracks are easy to occur. The welded joints of the welded mesh can not only bear the pressure, but also the shear force. The longitudinal and horizontal steel bars form a mesh structure that together acts as a bond and anchor. When the welded steel bars use smaller diameters and closer spacing, the increase in welding points per unit area is more conducive to enhancing the crack resistance of the concrete, which can reduce 75 More than% cracks occur.

Reinforced mesh is now widely used in various industries. People naturally hope that it has better quality, but its quality is also composed of many aspects. The following are several elements of the quality assurance of reinforced mesh proposed by Concrete Reinforcing Mesh Manufacturer:

Reinforced meshes have better welding processes in production. No matter what kind of environment this product is used in. They also need to have very good welding. Only when they have good quality in welding can it really improve its quality. One is that when the welding quality is improved, it can make it more beautiful. And also can make the product more robust. Material, material performance is the performance of the product.

If a manufacturer does not have good materials in production, it will naturally reduce its performance in use, or it will not have enough light weight in use, or it will not have better strength in use, etc. All are signs of quality degradation. So if you want to improve the quality of the mesh, you need to meet the production requirements on the material.

In the use of reinforced mesh, some also need anti-corrosion treatment, so at this time, its quality also depends on what kind of treatment the surface has, although some manufacturers have treated it, but the quality is not high enough and cannot achieve its due effect Therefore, in the process of user's use, there will be a decrease in appearance, corrosion resistance, weather resistance, etc., so this aspect also has a great impact on quality.
