The Concrete Structures Standard, AS3600, and the Reinforcing Steel
Standard, AS/NZS 4671, must be regarded as interrelated performance
standards. However, although a particular reinforcing steel may comply with,
or even exceed, some of the minimum requirements of its Standard, that steel
must not be used above the maximum stress limits set down in AS3600.

Grade R250N Plain Rod in Coils

This is a continuous length of semi-finished, low carbon steel, coiled hot as the
final part of the rolling process. Rod provides feed for material with finer
tolerances (eg, mesh bars), or is manufactured directly into fitments.
Rod diameters are not the same as bar sizes: rod is available in 0.5 mm
increments in the range 4 mm to 14 mm. Only selected sizes are used for
reinforcement as fitments.

Grade D500L Deformed Bar and Coil

This is a low carbon, deformed 500 MPa steel. The steel is produced in coils
by cold rolling, which is straightened to produce bars. D500L bar and coil are
available in sizes from 4 mm to 11.9 mm.

D500L

Grade D500L Mesh

Most automatically welded reinforcing fabrics in Australia are made of
deformed grade D500L bars. The bar diameters for the fabrics typically range
from 4 mm to 11.9 mm. D500L fabric is produced in standard 2.4 by 6.0
metre sheets, however purpose built sheets are available.

Grade R500N Mesh

This is a low carbon, round 500 MPa steel of Ductility Class N. The bar
diameter for the mesh is 10mm in both directions. R500N mesh is produced
as purpose built sheets to suit project requirements.

Grade R250N Plain and D250N Deformed Bars

Plain round bars and deformed bars, both of Grade 250, are also manufactured
as low carbon, hot rolled steels in straight lengths.

D250N bar is available ex-stock in 12 mm only, being primarily supplied for
construction of swimming pools. The D250N12 bar is designated as S12
reinforcement.

Grade D500N Deformed Bar

Grade D500N bar is produced as low carbon, hot rolled deformed bar in
straight lengths and in coils. Straight lengths are available from 12 mm to
40 mm diameter. 10, 12 and 16 mm diameter D500N bar typically are
supplied from coils.
