Product Information

Rubber Expansion Anchor bolt :

This is the world’s first “Rubber Expansion Anchor Bolt,” developed for fixing concrete buildings and road structures. The high-elasticity, high-performance rubber packing expands within the drilled hole, absorbing vibration and impact from the ground, preventing structural detachment. It also blocks water infiltration through the hole, solving leakage issues in buildings and contributing to long-term durability and reduced maintenance of structures.
