Product Overview: Chemical Anchor Bolt
The Chemical Anchor Bolt (CAB Series Chemical Resin Capsule Anchors) is an advanced heavy-duty structural anchoring fitting engineered for power plant construction, substation equipment mounting, cable management support systems, and heavy structural steel fastening. Manufactured by YiHao Power, our chemical anchor studs are produced from high-tensile carbon steel and A2-70 / A4-70 stainless steel alloys paired with premium vinyl ester resin capsules. Designed to satisfy international quality and performance standards for heavy construction fasteners, each Chemical Anchor Bolt delivers superior mechanical load distribution, vibration resistance, and long-term joint stability without damaging surrounding concrete.

Key Performance Features of Our Chemical Anchor Bolt
- Zero Expansion Stress in Concrete: Unlike mechanical expansion anchors, a Chemical Anchor Bolt creates an adhesive bond without outward expansion pressure. This allows for reduced anchor spacing and close edge-distance installations without cracking concrete base structures.
- Watertight & Corrosion Sealing: Synthetic resin fills the entire borehole, completely sealing out groundwater, humidity, and corrosive chemicals to protect both the stud shank and internal concrete rebar.
- Chisel-Point Stud for Automated Mixing: The specialized 45-degree chisel tip on the stud crushes the glass capsule and thoroughly mixes resin components when driven with a rotary hammer drill.
- High Dynamic Load Resistance: Excellent fatigue performance under heavy equipment vibrations, seismic shocks, and wind-shear stresses on outdoor transmission structures.
Installation Guidelines for Chemical Resin Anchors
Proper installation of a Chemical Anchor Bolt ensures maximum holding strength and structural safety. Follow these standard field practices:
- Borehole Drilling: Drill a hole in the concrete using a hammer drill matching the specified capsule diameter and embedment depth.
- Thorough Hole Cleaning: Clean concrete dust out of the borehole using a blow pump and steel wire brush repeatedly (blow-brush-blow process) to ensure optimal chemical adhesion.
- Capsule Insertion & Stud Driving: Insert the resin capsule into the clean hole. Attach a hex driving adapter to the chisel-ended Chemical Anchor Bolt stud and drive it straight in using a rotary hammer drill until it reaches the bottom.
- Curing & Torquing: Allow the resin to fully cure according to ambient temperature guidelines before applying load and tightening the nut to specification.
Primary Application Scenarios Across Power & Structural Facilities
Our premium chemical anchoring fasteners are widely deployed across global power and industrial projects, including:
- Heavy power transformer base plates, switchgear cabinets, and generator mounting.
- Heavy-duty overhead cable tray cantilever brackets, ladder rack supports, and busbar risers.
- Structural steel column bases, gantry legs, and curtain wall bracket attachments on concrete.
- Vibration-heavy machinery bases, crane rails, and industrial conveyor supports.
Frequently Asked Questions (FAQ)
Q1: Why is hole cleaning critical when installing a Chemical Anchor Bolt?
A1: Residual concrete dust reduces the bond strength between the resin and borehole wall. Thorough cleaning ensures maximum chemical adhesion and full load capacity.
Q2: Can chemical anchor studs be installed in damp or water-filled holes?
A2: Yes, high-grade vinyl ester resin capsules are water-resistant and can be cured in damp concrete conditions without losing bond strength.
Quality Assurance & Factory Testing
Every batch of Chemical Anchor Bolt products manufactured by YiHao Power undergoes rigorous quality control inspection before dispatch. Our testing protocols include stud thread tolerance checks, steel tensile proof load testing, chemical resin gel time testing, and concrete pull-out strength verification.
