SL51.5/ SL41.5 construction reinforcement mesh by AS-NZS 4671-2001 standard

Construction reinforcement mesh was made by plain steel wire.It main used on building construction complied with standard AS NZS 4671-2001.
The material is 250N,500N,500L,300E,500E ,the mesh size is 150x150mm, wire diameter is 5.3mm and 4.0mm and the overhang length is in both sides. These specificate is very pouplar in New Zealand civil engineering field.
More features of construction reinforcement mesh and ours as below:
  1. high quality raw material
  2. electric resistance welding machine made it which has firmly solder join,size precision,and appearance good-looking
  3. Professional management team
  4. Complete QC rules and regulations
  5. A full of laboratory testing instruments

Packing and shipment of construction reinforcement mesh by AS-NZS 4671-2001 standard:

Advantage of construction reinforcement mesh by AS-NZS 4671-2001 standard:
  1. Save 30% of steel bar dosages
  2. Reduce 50%-70% work time,improve construction progress and shorten construction period.
  3. Cut down 5%-10% construction cost
  4. 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 contractWire diameter of construction reinforcement mesh messured as per contract

Notes:
  1. 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.
  2. For 500L steel bars,only requriement for wire diameter is less than 5.0mm is RekL≥500

Material certificate of reinforcing mesh as below:
How can we conctrol our products quality for exporting Autralia?
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:
  1. Panel Size dimensions≤6m in length,there is 40mm tolerances.
  2. Panel size dimensions>6m in length,the tolerance is ±0.7%
  3. Wire diameter and mesh size measure and weld shear resistance test conformance to AS NZS 4761-2001 and as per contract.
  4. Weigh the each bundle weight to calculate each panel weight.
