Restraint Straps

Restraint straps connect timber systems to masonry walls in buildings. They are made from galvanised steel to prevent corrosion, and they come in different lengths and thicknesses for various construction needs. The main types we stock include 2.5 mm straps that are suitable for vertical loads such as securing plates to masonry walls and 5 mm straps for lateral support of roof trusses, rafters and joists. Both of these strap types help to prevent walls from bulging or cracking when they are exposed to wind pressure over time. The lengths of the restraint straps we stock range from 600 mm to 1500 mm. When choosing restraint straps, you can choose between light and heavy-duty options depending on the needs of your project. The products generally fall into categories based on their thickness (2.5 mm or 5 mm) and whether they're for vertical or horizontal use.

Building regulations state that these straps need to be used in several situations. Any solid or cavity wall needs roof lateral support, and walls that are longer than 3 metres also need floor lateral support. Internal load-bearing walls also need support at the top of each floor level. The rules state that walls should connect to floors above ground level every 2 metres. Vertical straps at least 1 metre long should be placed at eaves level and also every 2 metres. The main benefits of restraint straps include meeting building regulations, strong structural support, protection against wall movement and long-lasting performance through galvanisation.

Simpson Strong-Tie is a leading brand in this category with over 60 years of experience manufacturing construction connectors. They have a wide range of restraint straps designed to perform well even in tough conditions. By properly installing these simple but important components, builders can make sure that buildings remain structurally sound over the years and prevent the gradual weakening that can occur when walls aren't properly secured.
