The Simpson Strong-Tie Heavy Engineered Strap 1000mm (HES10B10) is a high-strength timber-to-masonry connector designed for lateral and vertical restraint in structural applications. Engineered from 1.5mm pre-galvanised steel, it features a 100mm bent end and formed edges for added rigidity. This strap replaces traditional 2.5mm and 5mm thick restraint straps, offering equivalent performance with less than 40% of the weight. It’s suitable for securing joists, rafters, and wall plates in roof and floor systems, and complies with BS EN 845-1 and CE marking standards.
