Galvanised straight restraint straps are a standard fix on any new build or renovation where timber roof structures meet masonry walls. These heavy duty straps are used to tie roof trusses, rafters and joists back to the supporting masonry, keeping the roof structure anchored against lateral movement. They comply with BS 5268 Part 3 and the relevant Building Regulations for horizontal restraint, so you are covered on any building control inspection without having to dig out a datasheet and argue the toss.

The straps are manufactured from galvanised steel, which gives them solid corrosion resistance for the long term. Once they are built into the structure, they are staying there, so it matters that the material holds up. Galvanising is the right choice here — hot-dip galvanised steel in a roof void is going to outlast any uncoated alternative without much debate.

Where Galvanised Straight Restraint Straps Fit Into the Build

Restraint straps sit in a fairly unglamorous part of the job. Nobody photographs them. But building control does check them, and a missed or incorrectly installed strap can hold up a sign-off. Getting the right length matters — too short and you cannot achieve the required fixing centres, too long and you are bending them to fit, which defeats the purpose of buying a straight strap in the first place.

These are available in six lengths from 600mm up to 1500mm, all at 30mm wide with a 100mm fixing zone, covering the range of wall thicknesses and joist depths you are likely to encounter on a typical domestic build or extension. The 10-pack format keeps things sensible on site — enough to work through a roof without having to count straps out one at a time from a loose pile.

Buying in bulk through DTS keeps the cost per strap low, which adds up quickly when you are strapping out a full roof or running multiple plots on a larger development.

Pro Tip: Always fix restraint straps to a minimum of two joists or rafters and into the masonry at the correct centres specified by building control — a strap nailed to a single joist at the end of a run will not satisfy the inspector and will need redoing.
