Rendabar load bearing beam from Treco Steel

Galintel Rendabars® are a total load bearing bar specificallydesigned for supporting brickwork above doors and windowsand to facilitate cement rendering.

The bonding of mortar to the brickwork and lintel forms acomposite beam of superior strength and structural adequacy.A minimum 1:4 mortar mix is to be used and applied to all facesbetween steel and bricks (vertical and horizontal leg). Bricks areto be of a strength at least equal to extruded clay bricks.

FULLY HOT DIP GALVANISED
All Galintel Rendabars® are fully hot dip galvanised to ensurethat all surfaces are fully protected. Brickwork cracking causedby rust displacement is virtually eliminated.

WIDER BASE SUPPORT
The width of the platform leg of each Rendabar® provides awide base of support for brickwork, and a generous keying areafor cement rendering.

COST EFFECTIVE AND LIGHTWEIGHT
Distinct advantages are derived from availability, low handlingcosts, and the elimination of priming, painting, andwire wrapping.

Galintel Rendabars® are considerably lighter than other forms oflintels, substantially contributing to ease of handling, speedsconstruction and reduces potential damage to green masonryduring placement.

STRUCTURAL RIGIDITY AND BONDING
Mortar bonding with the MRS (Multi Ribbed Section) locks theRendabar® firmly to the masonry by forming a composite beamthus ensuring superior lateral bracing and rigidity.Rendabars® have ample strength and ruggedness to withstandaggressive on-site handling and usage.

CONTROL JOINT INFORMATION
Where control joints are used as a required structural elementloading of the lintel should be reduced by one third.

COMPLIANCE WITH AUSTRALIAN BUILDING CODES
Galintel Rendabars® have been extensively tested by UnisearchLimited, the research and development company of theUniversity of New South Wales, for strength, structuraladequacy, and to ensure compliance with all relevant AustralianBuilding Codes. ABSAC approved (Technical opinion No.205).

The steel used conforms to the requirement of AS 3678-250,with a minimum ultimate tensile strength of 410 MPa and yieldstrength of 280 MPa.

Galvanising conforms to AS/NZS 4680:1999 and the relevantsections of AS 3700-1988. Steel in masonry construction shall beHOT DIPPED GALVANISED to the listed Australian standards andas such a minimum coating of 600g/m2 for any steel section of5mm or greater is required.

PROPPING
Rendabar® spans for each size must be propped or tommedequally when brickwork is laid up rapidly over and above two (2)courses. See below:
