ET expansion joints are technical solutions designed to absorb small movements in infrastructure such as bridges, roads, and concrete decks. Their main function is to ensure the continuity of the pavement against thermal expansion or structural movements, preventing cracks or damage to the surface.
This category includes several models: ET-30/50, ET-50, and ET-75, each adapted to different displacement levels, ranging from ±20 mm to ±37 mm. All are manufactured with high-strength components, such as metal plates, sealing elastomers, and adjustable anchoring systems with tightening torques of 70 Nm. Their dimensions and weight allow for rapid installation and compatibility with asphalt layers.
The transition (P) and leveling height (Q) are standardized to facilitate integration into civil engineering projects, complying with current technical regulations. These joints are ideal for sections that require precision and durability without compromising structural design or traffic safety.
In addition to their functional benefits, ET expansion joints also stand out for their ease of maintenance and ability to withstand dynamic loads. This makes them a comprehensive solution for projects where displacement is limited but constant.
