The Smart R-Bar™ is an Australian designed lightweight lintel used for supporting brickwork over openings.
Smart R-Bars™ are suitable for applications where a Render Finish is required. One side has holes making it easier for the render to stick to the angle.

• Load Tested in accordance with AS/NZS 1170.1:2002
• Australian Design Mark No. 201215561
• Cost advantages over other Render lintels.

150 x 100 x 6.0 -Safe load Table

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 

This 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.
