Steel Bonding Adhesive (Paste)
Structural Adhesives
Strong construction adhesives for bonding steel parts to concrete structures for structural strengthening
The steel bonding adhesive (paste)is a high-performance and labor-efficient epoxy material, engineered for structural strengthening and retrofitting. It is widely used for bonding steel plates to concrete, reinforcing load-bearing members, and securing equipment to structural surfaces, while ensuring high performance and structural reliability in critical construction environments.
Ideal for dry application scenarios, the adhesive offers high bond strength, easy handling, and excellent compatibility with concrete and steel substrates, making it suitable for both repair and reinforcement in civil, industrial, and infrastructure projects.
