This reinforcement construction mesh are made of ribbed steel bars bonded via spot welding for slab and wall constructions. The ribbed steel rod used can improve bonding to the concrete and minimize any concrete cracking that may occur as a result of concrete shrinkage. This feature enables the ribbed steel weld mesh widely used as building materials for block slab structure reinforcing, and hollowed slabs reinforcement, building wall reinforcement and support wall reinforcement. In practical uses, it is commonly used with bar chairs as supports.
