FAQs

• They are fire rated
• Renders stick very well to concrete
• They are dimensionally stable so cracking will be minimised
• They are more durable and not prone to rusting in a coastal environment

Ultralintel cross-sections are based on brick coursing module.

The 80mm high x 110mm wide Ultralintel is one course high

The 170mm high x 110mm wide Ultralintel is two courses high

The 80×110 Ultralintel is available in 11 lengths – 900, 1000, 1200, 1500, 1800, 2100, 2400, 2700, 3000, 3300, 3600.

The 170×110 Ultralintel is available in 9 lengths – 1000, 1200, 1800, 2400, 3000, 3600, 4200, 4800.

The length selected needs to be the clear span plus the bearing length at each end.

The 80×110 Ultralintel has a minmum bearing length of 100mm

The 170×110 Ultralintel has a minmum bearing length of 150mm

Prestressed concrete lintels can be cut using a high-speed cutting diamond disc designed specifically for masonry.

Dust generation can be minimised using a wet cutting method.

Make sure to use the correct safety equipment such as safety goggles and gloves.

There are no corrosion issues with the exposed high tensile strand at the ends.

Ultralintels are made with high strength concrete and can be drilled with a hammer drill ideally using an SDS drill bit.

The hole must be clear of the line of the prestressing strand.

The smooth ‘mould’ surface should be at the bottom and the rougher opposite surface at the top.

This rougher top surface facilitates a good bond with the brickwork mortar.

Ultralintels must be propped at intervals not exceeding 1500mm until the masonry mortar has matured.

Props should be positioned before the brick courses are laid on top.

Yes it does. The brickwork over acts compositely with the concrete Ultralintel to form a deep beam.

This is not the case with a steel lintel.

The load capacity of an Ultralintel depends on a number of factors.

The size of lintel selected, the clear span, the number of brick courses over and the type of wall it is supported on.

Refer Ultralintel load tables and the UltralintelDesigner for further guidance.

No it is not. The high tensile prestressing strand does not corrode in the same way that conventional reinforcing steel does.

True. Refer Ultralintel website for guidance.
