Joist hangers are used in place of plain nails and screws in structural applications for joining rafters and joists to beams and support bearers. They are used when building decks, pergolas and other structures that require very strong and stable joints.
Though joist hangers are more expensive than using nails and screws, they last much longer and support much heavier loads for an extended period of time. They also have a simple, fast installation process which even a beginner can master.
At Narangba Timbers, we have joist hangers in two widths – 50 mm and 45mm – in various heights like 90mm, 120mm, 140mm, 150mm and 190mm. Different shapes like U-shape, and ones with sloped plates are available.
Like with nails and screws, galvanised joist hangers must be chosen for outdoor applications and for use with treated timber. Choosing the correct size is very important as they cannot be modified in any way or reused for a different application. This will affect their load capacity and may cause the joint to fail after some time.
Always use the largest joist hanger possible, and fill all the nail holes with appropriate sized nails for a long-lasting rigid joint.
