Heavy Engineered Strap1200 bent 100

The innovative design of these new lightweight straps allows ease of handling and installation whilst maintaining the structural strength and robustness of much heavier weight straps.

Developed as an alternative to the traditional "heavy" and "light" restraint strap. They save time in installation in both horizontal and vertical applications and are CE marked.

The HES (heavy engineered strap) & LES (light engineered strap) replace traditional heavy restraint straps in roof and floor construction. Reducing the thickness to 1.5mm allows the HES strap to span over the top of floor joists and truss bottom chords of trusses without the need for notching.

HES straps are less than 40% of the weight, quicker to fit, and overcome many fixing problems associated with traditional heavy straps.

The LES is designed for vertical applications e.g. holding down wall plates, and is also CE marked.

*CE Marked.
*1.5mm thick.
*Formed edge design gives additional strength on bend.
*Complies with the BS EN 845.
*Lighter, less than 40% of the weight of traditional straps.
*Quicker to install - can fit over the top of floor joists and truss bottom chords.
*Easier to course with blockwork.
*No need to notch joists.
Building Regulations requires lateral restraint to be provided at each floor at a maximum of 2 metre centres and a performance requirement of 8kN ultimate capacity per horizontal restraint strap.

Restraint straps "perpendicular" to the floor joists are required to fix tight against the masonry and fixed across the first 3 joists, with a minimum of 8 square twist nails (2 per joist and 1 per noggin).

Restraint straps "parallel" to the floor joists are required to fix tight to the
masonry and be at least 1200mm long.

VERTICAL STRAP INSTALLATION: Vertical strapping at least 1 metre in length should be provided at eaves level at intervals not exceeding 2 metres. The lowest fixing should located within 150mm of the bottom of the vertical strap.
