Bridge rail is designed to reduce damages of car crash accidents caused by crossing the centerline and falling off edge of the bridges. It is made of aluminum alloy (6061-T6, 6063-T5) which has a semi-permanent resistance to corrosion.

KUKJE ST’s bridge rail offers not only greater durability but also higher passenger’s safety compared to other products that focus only on strength. The product has passed SB4 and SB5 grade of the vehicle impact test so as to be guaranteed its product performance.

Material
