Key Features of This Specific Profile
1. Optimized Rectangular Design
The 80 x 60 x 5 mm dimensions provide good stability with an asymmetrical profile that’s suitable for directional loading. The rectangular shape offers strong resistance to bending in the 80 mm direction while maintaining good compression strength.
2. Precision Manufacturing
Each tube is produced through pultrusion, where continuous glass fibers are pulled through a resin bath and precisely shaped. This creates a profile with consistent wall thickness and dimensional accuracy for reliable performance.
3. Material Composition
The specific glass fiber-to-resin ratio in this profile is optimized for structural applications, providing:
- Higher fiber content (65-70%) for high strength
- Specialized resin formulation for environmental resistance
- Uniform fiber distribution for consistent load handling
Typical Applications for the 80 x 60 x 5 mm Profile
This specific size is particularly suitable for:
Supporting Structures
The 80 x 60 x 5 mm profile provides good column strength for medium-height structures (3-5 meters) while its rectangular shape offers directional stability.
Railing Systems
The profile dimensions allow for comfortable grip size when used as handrails while providing sufficient strength for safety barriers.
Industrial Equipment Frames
The 5 mm wall thickness provides good fastener retention for mounting equipment, with the rectangular shape allowing for proper orientation.
Chemical Processing Environments
This profile’s specific dimensions provide sufficient material thickness to withstand prolonged chemical exposure; structural integrity depends on chemical and load conditions.
Installation and Usage Benefits
Simple Processing
- Cutting: Can be cut with standard carbide-tipped circular saws at 2000-4000 RPM

Frequently Asked Questions
How much weight can this 80 x 60 x 5 mm profile support?
This profile can support up to 3000 kg in compression according to manufacturer data when properly installed with a safety factor of 3. Actual capacity depends on installation configuration and load distribution.
What’s the maximum span for this profile when used horizontally?
For light duty applications (pedestrian load), this profile can span up to 1.5 meters with acceptable deflection. For heavier loads, engineering calculations are recommended.
Is this profile UV stable?
Yes, our 80 x 60 x 5 mm tubes include UV inhibitors that help resist degradation and color fading. They mechanical properties can be retained over long service life depending on exposure.
How do I specify this product for my project?
Reference “FRP Rectangular Tube 80 x 60 x 5 mm” with standard length requirements. If custom lengths or finishing are needed, specify these requirements when ordering.
Is this profile fire resistant?
The standard version has a flame spread rating of 25 (Class A). Fire-retardant versions available upon request for special applications requiring enhanced fire performance.
