Product Description

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

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.
 

Clearly ribbed on the surface	Firmly weld spot
Accurately wire diameter	Mesh space messured
Uniform mesh spaces	Flat 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.
The skatch of reinforcing mesh as below:

NL= Number of longitudinal bars PL= pitch of longitudinal bars dL= diameter of longitudinal bars NC=Number of transverse bars	L= length of longitudinal bar B=Length of transverse bar u1=Overhang of longitudinal bars                                       u2=Overhang of longitudinal bars

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 R_ekL≥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.
