High-Performance Pultruded FRP Flat Bar

Our pultruded FRP flat bar is manufactured using a continuous pultrusion process that produces high-strength, uniform fiberglass-reinforced profiles. The flat bar features unidirectional glass fiber reinforcement embedded in a premium thermosetting resin matrix, delivering exceptional tensile strength and dimensional stability.

Unlike traditional steel flat bars, FRP flat bar is completely corrosion-resistant, non-conductive, and non-magnetic. It weighs approximately 75% less than steel while offering comparable strength in tension. This makes it an ideal choice for applications where weight reduction, electrical insulation, or corrosion resistance is critical.

Available in a wide range of standard widths from 10 mm to 200 mm and thicknesses from 3 mm to 25 mm. Custom dimensions can be produced to meet specific project requirements. The smooth surface finish allows for easy painting, bonding, or additional coating applications.

Features & Benefits

Features

Corrosion Resistance

Inherently resistant to moisture, chemicals, saltwater, and UV degradation. Will not rust, rot, or corrode like steel or wood, ensuring decades of maintenance-free service.

High Strength-to-Weight Ratio

Approximately 75% lighter than steel with comparable tensile strength. Reduces structural load requirements and makes handling and installation significantly easier.

Electrical & Thermal Insulation

Non-conductive and non-magnetic with excellent dielectric properties. Low thermal conductivity prevents heat transfer, making it ideal for electrical infrastructure applications.

Dimensional Stability

Low coefficient of thermal expansion ensures consistent dimensions across temperature variations. Maintains shape and performance in extreme environments.

Easy to Fabricate

Can be cut, drilled, machined, and bonded using standard tools and techniques. No special equipment required for on-site modifications.

Long Service Life

Designed for a service life exceeding 20 years in harsh environments. Low life-cycle cost compared to traditional materials that require frequent replacement.
