The steel profiles in this system can consist of extrusion profiles. Our expansion joints are designed according to ISO9001 quality standards, DIN 1072 and AASHTOH30-S24 load standards and the anchorage elements used in the expansion joints are produced in accordance with EN 10025 standard and rubber waterproof seal EN standards. The expansion joint can be manufactured as one piece up to 12 m and after 12 m, the expansion joint can be divided into two pieces after apporved by customer. In the cases where the join (connection part) of the expansion joint is outside of the walkway, the join must be at the place where the vehicle traffic is minimum. To protect the profile against corrosion, the surface of the profile must be cleaned, the primer paint is applied just after sandblasting is applied in the sa2 1/2 quality The profile is coated at least 80 micron zinc-based primer and on the top of the coat, at least 100 micron chlorine-rubber-based or epoxy-based paint is applied to protect against corrosion and external effect.
