Product Description


RL718/RL818/RL918/RL1018/RL1118/RL1218 Rectangular reinforcement steel mesh
Reinforcement steel mesh was welded by automatic electrical resistance welding machines conformance to standard AS-NZS 4761-2001.
The material of reinforcement steel mesh is 250N,500N,500L,300E,500E.
Reinforcement steel mesh is very poupular in civil engineering and construction.It always used on road subgrade,building foundation,tunnel support and reinforced,mine and coal reinforced and support,bridge construction etc.
During construction works,It is not only increase our working speed and time but also save 75% construction cost and enhance the crack resistance.
The specification of rectangular reinforcement steel mesh as below:

- Grade 250N is supplied as plain round reinforcing steel complying with AS 3679.1,exceptthe tolerance of the diameter and roundness dosen't apply it.
- For 500L steel bars,only requriement for wire diameter is less than 5.0mm is RekL≥500
Material certificate of reinforcing mesh as below:

Firstly,we purchase the material from Steel Factory and inspect chemical composition and mechnical property of reinforcing mesh panel in our in-house laboratary according to AS 1554.3.
Secondly,the panel size tolerances meassure way as:
- Panel Size dimensions≤6m in length,there is 40mm tolerances.
- Panel size dimensions>6m in length,the tolerance is ±0.7%
- Wire diameter and mesh size measure and weld shear resistance test conformance to AS NZS 4761-2001 and as per contract.
- Weigh the each bundle weight to calculate each panel weight.
