The HES (heavy engineered strap) replaces 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 the bottom chords of trusses without the need for notching.
Complient with BS EN 845-1, Simpson Strongtie heavy engineered restraint straps are less than 40% of the weight, quicker to fit and overcome many fixing problems associated with traditional heavy straps.
