Steel expansion profiles e-straight are used for pouring concrete industrial floors with a thickness of 140 - 220 mm. The straight e-straight joint can be easily combined with the sinusoidal e-slide joint in non-traffic areas, thus reducing the cost of purchasing an expansion joint. These profiles are based on the same "omega" construction as e-slide expansion joints, with a 3D anchorage system, and differ only in the upper profiles, which will be visible after concreting as straight or sinusoidal. Both carry the same static loads.
