FRP Bolt is manufactured using fiberglass pultrusion or compression molding. It is lightweight yet high-strength, corrosion-resistant, anti-aging, non-conductive, and non-magnetic with no electrochemical corrosion, offering excellent insulation properties and resistance to rust. It provides convenient installation, can be cut to custom lengths, features high thread precision, and adapts well to various connection scenarios with a long service life. FRP Bolt serves as an alternative to traditional metal bolts, perfectly adapting to corrosive and insulating environments.

Manufacturing Process
FRP Bolt is manufactured using pultrusion or compression molding processes. It utilizes glass fiber roving as the reinforcing material and epoxy resin as the matrix, with the addition of reinforcing and anti-aging additives. It is cured and formed at high temperatures to produce a precise thread structure. The entire process is automatically controlled to ensure dimensional accuracy and thread quality. The product leaves the factory only after passing tensile, shear, and insulation testing.
Applications
Widely used in sectors such as electric power, telecommunications, chemical processing, metallurgy, and construction. They are ideal for connecting components in corrosive environments and insulation-critical applications-including cable supports, chemical equipment, insulating structures, and outdoor facilities. They are particularly suitable for harsh operating conditions where metal bolts would be prone to corrosion or electrical conductivity, ensuring secure and safe connections.
FAQ
Q: Do your products come with third-party authoritative test reports and quality certifications?
A: Yes, our FRP bolts meet national and international standards; they are supplied with a certificate of conformity and support third-party on-site pull-out re-testing.
Q: How does the total cost of using FRP bolts compare to traditional steel bolts?
A: Although the unit price is slightly higher than standard steel, their lightweight nature significantly reduces transportation and installation labor costs. Combined with zero maintenance requirements, the total lifecycle cost is lower.
Q: Can the product length and specifications be customized to meet our project requirements?
A: Yes, we can customize diameters, lengths, and special anti-slip surface patterns based on your construction drawings.
