The Straight Profile is a modern leave-in-place expansion joint for concrete pours. It forms a secure day joint, reinforces the concrete edges on both sides of the joint, and acts as a load-transfer system between adjacent slabs.
The design avoids welded elements in the working parts of the profile (except anchors), which helps keep precision and reduces the risk of deformation from high temperatures during fabrication or site welding. A centering system for the upper strips, together with the load-transfer arrangement, helps adjacent slabs stay aligned — including with joint openings of up to 30 mm.
For openings greater than about 10 mm, select dowel size and thickness carefully so the joint stays aligned under load. The system is engineered with reference to industry practice including TR 34, 4th edition, and Eurocode 2 EN 1992-1-1.
