Chemical anchor bolt

Mechanical expansion anchors rely on outward pressure against the concrete wall, which can relax in cracked or deteriorating concrete. Chemical anchors bond the bolt to the substrate using adhesive resin, distributing load across the entire embedment depth. This provides higher load capacity, better performance in cracked concrete, and superior resistance to vibration and seismic forces.

Curing time is influenced by resin type, ambient temperature, substrate temperature, and hole condition. At 20°C, polyester cures in 5–30 minutes, epoxy in 15–60 minutes, and vinylester in 10–45 minutes. Lower temperatures extend curing times. Always refer to the resin manufacturer's data sheet for temperature-adjusted curing schedules and full-load cure times.

Yes — specially formulated epoxy and vinylester resins are available for wet and underwater applications. These systems are designed to displace water during injection and cure reliably in moist environments. Standard polyester resins are not suitable for wet conditions and should be limited to dry installations.

All parameters are customizable: material grade (carbon steel, stainless, galvanized), diameter (M6–M48), length (up to 600mm), thread type (metric, UNC, UNF, BSW, or custom), resin system (polyester, epoxy, vinylester, injection mortar), capsule or injection format, and special coatings for corrosive environments.
