คำอธิบายสินค้า

Brief Introduction

Single gap expansion joint is a strip seal joint, which consists of two steel edge profiles with anchor loops and a replaceable sealing profile. The strong anchor loops ensure the reliable anchorage of expansion joint with bridge structure. On the anti-corrosion side, the steel profiled should be in accordance with ISO12944 or other national standard as requested,such as ASTRA, RVS and ACQPA.The sealing profile is firmly connected with the steel edge profiles and meanwhile it ensures 100% water-tightness.

Single gap expansion joint allows a longitudinal movement capacity up to 80mm. It is designed for bridge heavy traffic load and can be used for both bridge structure and building structure.

Single gap expansion joint can be designed and manufactured with noise-reduction plates to reduce the noise greatly when traffic passes.
