Simpson Strong-Tie HES10B10 1000mm Heavy Engineered Bent at 100mm Pack of 50

A direct replacement for traditional restraint straps, the innovative design of these lightweight straps allows ease of handling and installation whilst maintaining the structural strength and robustness of much heavier weight types. The HES (heavy engineered strap) replace the traditional heavy (30 x 5mm) restraint straps in roof and floor construction. Reduced thickness allows the HES strap to span the bottom chords of trusses and over floor joists 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. Approved Document A of the Building Regulations requires lateral restraint to be provided at each floor at a maximum of 2 metre centres Restraint straps “perpendicular” to the floor joists are required to be held tight against the masonry and fixed across the first 3 joists Restraint straps “parallel” to the floor joists are required to be held tight to the masonry and be at least 1200mm long The characteristic tensile strength for horizontal restraint straps should not be less than 8 kN Formed edge design gives additional strength on bend Quicker to install - can fit over top of floor joists and truss bottom chords Easier to course with blockwork No need to notch joists Complies with BS EN 845-1
