Transflex®TR50-TR380 - Standard Bridge Expansion Joints - Trelleborg Bridge Expansion Joints

Transflex®TR 50 - TR 380

The Transflex® design is based on steel reinforced rubber modules, which absorb expansion, contraction, translation and rotation movements with remarkable comfort to traffic, effectively sealed, low maintenance and easy replacement. Transflex® models are numbered from TR 50 to TR 380, and cover a movement range from 50mm to 380mm, and oblique movements of up to 90° of skew.
