Why Choose 200 x 200 x 10 mm FRP Square Tubes?
Cost-Effective Structure
These specific-sized tubes offer an optimal balance between material usage and structural performance. The 10 mm wall thickness provides high load-bearing capacity while maintaining a favorable weight-to-strength ratio. For structural frameworks requiring 200 mm profile width, these tubes deliver reliable performance without excessive material costs.
Perfect for Medium to Large Frameworks
The 200 x 200 mm profile size is particularly well-suited for:
- Medium-span support beams (3-5 meters)
- Column structures in aggressive environments
- Equipment support frames in chemical plants
- Main structural elements in platforms and walkways

Frequently Asked Questions
How much weight can a 200 x 200 x 10 mm FRP square tube support?
Under distributed load conditions, our 200 x 200 x 10 mm tubes load capacity depends on span, support conditions and application; engineering calculations available on request. For your specific application, we provide detailed load tables and engineering calculations upon request.
Is this size appropriate for building a platform framework?
Yes, this 200 x 200 x 10 mm dimension is ideal for platform structures with moderate loads. It’s commonly used as the main structural element in platforms ranging from 3×3 meters up to 6×6 meters depending on load requirements and support spacing.
Can these tubes be painted to match existing structures?
While painting isn’t necessary for protection, our 200 x 200 x 10 mm FRP tubes can be painted with epoxy or polyurethane paints for aesthetic purposes or color-coding. Surface preparation with light sanding is recommended before painting.
What’s the expected lifetime of these profiles in outdoor use?
Our 200 x 200 x 10 mm FRP tubes with UV inhibitors have a designed for long service life in many outdoor environments, even in harsh weather conditions. Unlike metal alternatives, they resists rust and corrosion, or require periodic repainting.
How are these FRP tubes more cost-effective than steel despite the higher initial cost?
While the initial material cost is higher, the total installed cost is often lower due to:
- weight reduction can minimize installation equipment and labor
- No welding required, reducing skilled labor needs
- No painting or corrosion protection needed
- Reduced maintenance costs over decades of service
- Reduced replacement costs due to long service life
Are custom lengths available for the 200 x 200 x 10 mm profile?
Yes, while our standard lengths are 3m, 6m, 9m, and 12m, we can provide custom lengths to reduce waste and simplify installation for your specific project. Minimum order quantities may apply for custom lengths.
