The flat washer is mainly punched out with iron plate. It is generally a flat washer with a hole in the middle. The size and specification of this hole are generally determined according to customer requirements.

2. With a tight steel bar spacing, the longitudinal reinforcement of the welded wire mesh and the transverse ribs form a network structure together to act as a bond anchorage, which helps to prevent the occurrence and development of concrete cracks. The welding nets on the road surface, floor and floor can reduce the concrete. The surface cracks about 75%.
3. It is especially suitable for large-area concrete projects. The mesh size of the welded mesh is irregular and far exceeds that of manual ligating meshes. The mesh sheet has large rigidity and good elasticity. When the concrete is poured, it is not easy to locally bend, deform, and produce slippage. The thickness of the concrete protective layer is easy to control and uniform, and obviously improves the quality of the reinforced concrete project.
4. Welded mesh has good comprehensive economic benefits. The design strength of welded mesh rebar is 50% higher than I-grade rebar (smooth steel rebar welded mesh) ~ 70% (ribbed steel rebar welded mesh). It can still be considered after considering some structural requirements. Saving about 30% of the steel bars, plus the processing cost of the scattered reinforcement steel with the diameter of 12mm or less is about 10% to 15% of the material cost. Comprehensive consideration (compared with Grade I steel) can reduce the engineering cost of steel bars by about 10%.
Flat washers are usually thin pieces of various shapes used to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. Many materials and structures have such components to perform similar functions. Due to the material and process limitations of threaded fasteners, the bearing surface of bolts and other fasteners is not large. Therefore, in order to reduce the compressive stress of the bearing surface and protect the surface of the connected parts, washers are used. In order to prevent the looseness of the connecting pair, anti loose spring washers, multi tooth lock washers, round nut lock washers, saddle shaped, wavy and tapered elastic washers are used.
What is the difference between artificially meshed steel mesh and welded steel mesh?
1, can greatly reduce the installation of steel bars, the use of less than 50% -70% of man-hours.
