Board corner joints

Our PVC corner joint sections, which are also known as board corner joints, are designed to fit into boards which are positioned at a 90 degree angle. As well as providing support, board corner joints can hide and protect cut ends of boards and panels. Materials that can be pushed into the profile include foamex, plywood, glass and other commonly used materials.

Our universal corner joints are suitable to be used as both internal and external corner joints.

Who uses plastic corner joints?

Typically customers from the signage, building, shopfitting, display and exhibitions stand industries use plastic corner joints. However, as with all our plastic profiles, we have customers from a wide range of sectors. Although these plastic joining profiles are not structural, they give a clean appearance when covering 90 degree joints.

Plastic corner joints made in the UK

Our PVC plastic corner joints are made at our factory in the UK. Our extruded profiles are high quality products and we are accredited with the British Quality Standard ISO 9001:2015 which gives peace of mind to our customers.
