Steel used in the edge of the joint element, and all the anchor elements (anchor plates, anchor hoops) minimum DIN ST 37-2 (EN 10025 S235JRG2) quality. Multi-span joints, middle longitudinal profiles, the minimum DIN ST 52-3 (S355J2G3 EN 10025) quality is selecting.

Expansion joints up to 12 m is produced one piece, when joints is exceeding 12 m length by the approval of costumer shall consist of two parts. Necessary joints should chosen out of impact of vehicle traffic areas or minimum impact of vehicle traffic areas.

Against corrosion surface cleaning of steel profiles will be sand blasted with quality of sa2 1/2 and without waiting primers will be applied. At least 80 microns of zinc based primer and at least 100 microns chlorinated rubber or epoxy resin coating paint will be applied against to rust of external influences.
