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.
the steel bar after drawing shape as below figure:
- 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.
- 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.
- Each sheet of reinforcing mesh panel shall include number of bars,pitch,length,width, and overhang dimensions. And the bar arrangement of panel has single bars, twin bars or combination of single bars and twin bars.
- is contained composition and characteristic mechanical porperties of reinforcing steels.

We are .
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:
