Structural Profiles - Solid Round Rod (Isophthalic)

Application Scenarios

Isophthalic solid round rods are commonly used for support, connection and load-bearing components that require both strength and corrosion resistance, such as platform handrail posts, grating support rods, equipment tie rods and various structural reinforcements. In high-humidity, acid-base or salt-spray environments, the isophthalic resin system can provide more stable long-term performance, making it suitable for working conditions in chemical, water treatment, marine and power industries. For specific application recommendations, please contact us to confirm based on your working conditions.

Selection Guide

When selecting, focus mainly on the required diameter, load form (tension/compression/bending), support span and the corrosion level of the service environment, and use these to determine the required cross-sectional size and resin system. Isophthalic solid round rods are more suitable for occasions with stronger corrosiveness or higher durability requirements; for general indoor structures, cost can be evaluated comprehensively. You are welcome to contact us with your working condition parameters so we can help match the appropriate specifications.

Product Advantages

This product uses glass fiber as reinforcement and resin as matrix, and is formed by impregnation, heating curing and pultrusion. It features light weight, high strength, corrosion resistance, electrical insulation and non-magnetic properties, and is easy to cut and machine. The solid round rod has a dense cross-section, stable compressive and flexural performance, and is convenient for drilling, turning and combined installation with other structural parts. Compared with traditional metal materials, it can reduce maintenance requirements in corrosive environments.

Service Environment

• This solid round rod is produced with isophthalic resin, offering enhanced water resistance and broad resistance to corrosive media, and is suitable for indoor and outdoor installation.
• Typical service environments for this FRP structural profile include humid and chemical exposure areas, such as industrial plants, wastewater treatment facilities, and marine or coastal areas where steel would corrode.
• The pultruded glass fiber reinforced structure allows this round rod to be used over a wide temperature range without losing structural integrity; please contact us for detailed temperature performance data.
• Because the material is non-conductive and corrosion resistant, it is often used in applications near acids, alkalis, salts and other aggressive media; specific chemical compatibility should be confirmed with our technical team.
