BlueScope’s steel building products business, Lysaght, has made its popular KLIP-LOK® steel roofing an even more attractive choice with the introduction of the new LYSAGHT LOK-KLIP™ end joint/expansion joint system.

Fast, effective and safe to use - this innovative product enables builders and roof fixers to easily and quickly install weather resistant end and expansion joints between overlapping sheets of LYSAGHT KLIP-LOK 700 HI-STRENGTH® or KLIP-LOK CLASSIC® 700 roof sheeting.

Since its introduction by Lysaght in 1958, KLIP-LOK® roofing has been a popular choice with architects, designers, builders and building owners because of its clean lines uninterrupted by fasteners.

The low profile of the LYSAGHT LOK-KLIP™ system, compatible with both steel and translucent sheeting, maintains the long clean lines of the KLIP-LOK® profile without cluttering the roof space with clearly visible step joints.

Comprising a fully engineered bracket manufactured from 100% Australian made ZINCALUME® steel and custom shaped weather resistant polyethylene strips, the LYSAGHT LOK-KLIP™ system has been fully tested under cyclonic and non-cyclonic conditions for weather resistance and wind uplift performance in Lysaght’s own NATA accredited testing facility.

The new LYSAGHT LOK-KLIP™ system proved itself recently when used by Maroochydore roofing specialist Regan Projex on Stockland’s Brightwater Market Place project on the Sunshine Coast. The project called for the installation of over 3000 square metres of LYSAGHT KLIP-LOK HI-STRENGTH® steel cladding manufactured from COLORBOND® steel in the colour Surfmist®.

“When we were planning this project Lysaght’s roofing experts suggested using their new LYSAGHT LOK-KLIP™ solution for the step joint half way along the skillion roof,” Ashley Regan, owner of RPX said.

“We were working with sheet lengths up to 29.3 metres, so thermal expansion was an issue. “We do a lot of long length roofing and while fixing the sheets is a pretty quick process, expansion joints can take time, especially if you haven’t got a good system to use.”

The unique LOK-KLIP™ bracket is secured to the bottom sheet using standard roofing fasteners and is designed to hold the top sheet firmly against the profiled polyethylene weather resistant strip thereby creating the weather resistant seal, all while maintaining LYSAGHT KLIP-LOK® roofing’s ability to accommodate normal thermal expansion and contraction.

“Actually it’s not very complicated,” Ashley Regan said. “Our crew went cautiously at first because they hadn’t used the LYSAGHT LOK-KLIP™ system before, but after four or five sheets it was a breeze. It’s very simple”.

Because roof installation using the LYSAGHT LOK-KLIP™ system can be faster than incorporating traditional step joints, shorter sheet lengths can be economically utilised avoiding the potential site and handling issues of longer roof sheets. Without the additional purlin detailing required for conventional step joints, the LYSAGHT LOK-KLIP™ system can also save you money.

The LYSAGHT LOK-KLIP™ solution is the next step in the evolution of one of Australia’s most popular, and proven, industrial and commercial roofing systems.
