  • Australian Design Mark No. 201215561
  • Cost advantages over other Render lintels.
  • Proudly Australian Designed and made to Australian Standards

Features are:

  • Hot Dip Galvanised to AS/NZ 4680:2006
  • R3 Durability Rating in accordance with AS/NZS 2699:2002
  • Light weight when compared to traditional Concrete/Brick Lintels
  • Available in a range of sizes.

Note:

  1. a minimum of three courses of bricks must be laid above the lintel beam.
  2. Load limited by deflection of 1/600 span.
  3. Yielding stress fy=235 Mpa, tensile strength fu=375Mpa for both legs.
  4. Mass per metre calculation is based on 7850kg/m^3.
  5. Calculate bar length is span+150mm each end.

Notes on Safe Load Tables 

Tis product is imported from China, material used is Q235B, and here Q stands for yielding.
According to PRC National Standard GB700-88(previous version GB700-79 part A3 & C3), the minimum yielding point is 235Mpa for thicknesses less than 17mm, tensile strength is between 375-400MPa.

  • The B and R bars are simply supported at both ends.
  • The B and R bars loaded such that the load acts vertically and equally on both sides of the web.
  • Loads given are total (allowable) loads including lintel and brickwork.
  • UDL loads are constant along the length of the bar.
  • Point loads act at mid-span.
  • 150mm minimum bearing support on to brickwork.
  • Hot-dip galvanising to AS / NZS 4680:2006.
  • Loads are in accordance with AS / NZS 1170.1:2002.
