Welded wire reinforcement is adopts cold-rolled high tensile steel wire.
It is welded by an automatic welding machine by "electric resistance welding method",
The weld strength at the intersection of steel wires provides mechanical anchoring of the welded wire reinforcement,
Because of the higher yield strength of low-carbon steel wire, it can effectively reduce the used amount compared to rebar.
In advanced countries such as Germany, the United States, and Singapore,
Welded wire reinforcement is widely used in construction and civil engineering.
The yield strength of steel wire (500MPa) is higher than that of rebars (280MPa).Theoretically, it can save 44% of the amount of rebars. The actual construction of overlapping joint and loss can save about 30% of the amount of rebars.
Save 50~75% of working hours::The Welded wire reinforcement can be easily installed and can be free of manual binding. The Welded wire reinforcement has a large construction area per labor unit, which can greatly shorten the working hours by 50~75%.
Improve construction quality:The precisely Welded wire reinforcement will not be shifted or even loosened due to stepping during the construction period, avoiding the mistakes of missing or wrong binding due to manual binding, and can improve its construction quality compared to rebars.
Save raw materials:When the growing shortage of raw materials, Welded wire reinforcement can save 30% of the use of rebars,which greatly reduces the carbon emissions caused by the production and transportation of raw materials.
Prevent cracking:The rebars is not bound exactly executed, which causes the wire to fall off. The Welded wire reinforcement can prevent loosening due to the high welding strength of the welding point and evenly distribute the binding force in the vertical and horizontal directions, avoiding stress concentration and effectively preventing cracks.
