Profile Standards


Profiles are supplied as cold rolled and electroplated.

Chemical Composition – % Max

Note — The carbon equivalent (CE) is determined in accordance with the equation from AS/NZS 1163:2016 – Grade:C350LO CE = C + Mn/6 + (Cr+M0+V)/5 + (Ni+Cu)/15

Mechanical Properties


  • Test specimens are to be taken longitudinally from a major flat portion of the section. Test frequency is as per AS/NZS 1163:2016.
  • The yield, tensile and elongation will be determined in accordance with AS 1391, with samples artificially aged to a temperature of 180 degrees for a period of not less than 15 minutes.

Impact Testing
Impact testing as described in Section 10 of AS/NZS1163:2016 is performed at O°C in accordance with AS 1544.2 on all profiles (flats, angles and channels) with a nominal thickness of 6mm or greater.

Coating Thickness
All profiles are electroplated to a thickness of 50 grams per square metre per side (ZIOO). The profiles are then coated with a solvent based Clearcote to a thickness averaging between 14 and 20 microns.

Surface Finish
Product shall be free from lamination, surface flaws and other defects detrimental to its use for structural purposes.

Angles and Channels are available in 6 and 9 metre lengths. Flats are available in 6 metre lengths.
Non-standard lengths by inquiry.

End Condition
Profiles are supplied with mill cut ends. End coding is applied in accordance with AS/NZS 4496:1997.
