Most purlin anchors suit timber widths from roughly 45 mm to 100 mm, with the throat matched to common sections such as 47×100 or 75×150 mm. Choose an anchor whose seat width matches your timber thickness so the member sits flush without packing.

Yes, purlin anchors are typically made from pre-galvanised or hot-dip galvanised steel, giving corrosion resistance for exposed roof, carport and timber-frame use. The zinc coating protects the bracket in damp or outdoor conditions and suits permanent structural applications.

A purlin anchor is fixed to masonry with expansion bolts or masonry anchors through the base plate, then the timber purlin is secured into the strap or seat with nails or screws. Position the anchor so the timber bears fully on the seat and fill all fixing holes for maximum hold.

Purlin anchors are usually supplied as the bracket only, without nails, screws or masonry bolts, so fixings are chosen to suit the timber and substrate. GeZu Impex lists each anchor's steel gauge and hole pattern so you can pair it with the correct structural screws or galvanised nails.
