PRODUCT DESCRIPTION

Reinforcing mesh was made by deformed bar after drawn, which is accorded to Australian/New Zealand Standard AS-NZS 4671-2001. The material is 250N, 300E, 500L, 500N and 500E, the mesh spaces is 200mm, there is two sides overhang which is 100mm.

Uniform mesh spacesFlat and smooth mesh surface


the steel bar after drawing shape as below figure:

1. The angle of the rib or inclined indentation of the reinforcing mesh panels' bar isn't less than 45°. The angle scope is greater than 45° and is less than 70°, the rib height is from 0.025d to 0.10d.

2. The reinforcing mesh panel includes transverse and longitudinal bar, pitch and overhang. The Australian and new zealand's market, the normal panel size is 2.4m*6m.Because of containers size, we always advise our cutomer to make the panel size to be 2.2m*5.8m. It can be easy to be load and save more USD1000 per container for packing and loading cost.

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

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:

SL52/SL62/SL72/SL82/SL92/SL102/SL81 Square reinforcing mesh

a. Panel Size dimensions≤6m in length, there is 40mm tolerances.

b. Panel size dimensions>6m in length, the tolerance is ±0.7%

c. Wire diameter and mesh size measure and weld shear resistance test conformance to AS NZS  4761-2001 and as per contract.

d. Weigh the each bundle weight to calculate each panel weight.
