Pergola corner connectors are made to fit common square posts such as 70×70, 90×90 and 100×100 mm, with the connector's internal width matching the post section. Measure the actual post width, including any planed reduction from the nominal size, before ordering. Some models are supplied in size options or with an adjustable seat to suit slightly different timbers.

Galvanised steel pergola connectors are made for permanent outdoor use, as the zinc coating protects against rain and humidity in a garden structure. For coastal sites or long service life, hot-dip galvanised or stainless steel connectors resist corrosion best. Keeping the timber sealed and letting water drain from the connector also extends its life.

Pergola post connectors are fixed by driving screws or bolts through the pre-drilled holes in each arm into the post and beams. Use structural wood screws or coach bolts sized for the hole diameter, and fill every hole for a rigid joint. Wall and floor versions add anchor bolts into masonry or concrete to tie the frame down.

Some pergola corner brackets include matching screws or bolts, while others are supplied bare so you choose the right structural fixings, so check each product's specification. GeZu Impex offers the connectors alongside post supports, angle brackets and beam shoes so a whole pergola frame can be built as a set. Pair corner connectors with post-base anchors at the ground and beam connectors along the rafters.
