The bar-mat reinforcement is manufactured by strapping or welding longitudinal reinforcement and transverse reinforcement in cross, and is one of “10 new techniques for popularization and application of construction industry in 2005”.
Calculation of theoretical weight of bar-mat reinforcement:
heoretical weight of bar-mat reinforcement (KG) = length of reinforcement (M) * wire diameter (MM) * wire diameter (MM) * 0.00617(φ10reinforcement 0.616539kg/m)
The bar-mat reinforcement is applied in fields such as industrial and civil beam column, floor, roof, wall, concrete pavement, bridge deck, airfield runway, tunnel lining, box culvert, wharf, terrace and prefabricated part, etc.
Advantages
It significantly improves quality of reinforced engineering.
It significantly improves construction speed.
It strengthens crack resistance of concrete.
It creates good composite economic results.
Common Specification
Specification of bar-mat reinforcement: width: 2M, length: 6-8M; mesh: 10-20CM
