Packing and shipment of construction reinforcement mesh by AS-NZS 4671-2001 standard:
Advantage of construction reinforcement mesh by AS-NZS 4671-2001 standard:
- Save 30% of steel bar dosages
- Reduce 50%-70% work time,improve construction progress and shorten construction period.
- Cut down 5%-10% construction cost
- Used widely,it has a good market development prospects.
How can we measure our construction reinforcement mesh:
| Tensile stregth test of construction reinforcement mesh as per contract | Wire diameter of construction reinforcement mesh messured as per contract |
| Overhang of construction reinforcement mesh messured | Mesh spaces of construction reinforcement mesh messured, |
| Width of construction reinforcement mesh messured as per contract | Lengh of construction reinforcement mesh messured as per contract |
Application of construction reinforcement mesh by AS-NZS 4671-2001 standard:
building construction,highway road reinforcement,bridge support,tunnel reinforced,mine and coal reinfocing

- 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.
