What fixings and connections are appropriate for landscape timber?

For ground-contact landscape timber, all fixings must be stainless steel (A4/316 grade) or hot-dip galvanised to minimum 85 µm coating thickness. Standard zinc-plated fixings will corrode within 2–5 years in contact with treated or acidic timber.

For ground-contact landscape timber, all fixings must be stainless steel (A4/316 grade) or hot-dip galvanised to minimum 85 µm coating thickness. Standard zinc-plated fixings will corrode within 2–5 years in contact with treated or acidic timber. Connection methods include: coach screws (M10–M12) for timber-to-timber joints, threaded rod with resin anchors for fixing to concrete, galvanised steel angles and brackets for right-angle connections, and stainless steel wire rope for tensioned palisade systems. Avoid dissimilar metal contact (galvanic corrosion) — use nylon washers between different metals.
