When chemical resistance matters, FRP U Channels (or what old-timers call fiberglass U beams) outperform metals every time. At Hongwo, we’ve been refining these composite U profiles since 2008 - and let me tell ya, the maintenance savings alone will make your operations manager do a double take.

Available in three industry-standard sizes:
Dimension, Weight and Load Capacity Comparison Table
| Dimensiom(mm) | weight(kg/m) | Load Capacity(kN/m) |
| 50*25 | 1.8 | 12.5 |
| 75*4 | 3.2 | 28.0 |
| 100*50 | 5.1 | 45.6 |
Material Performance Comparison Table
| Property | Hongwo FRP | Aluminum | Steel |
| Corrosion Resisttance | Excellent | gOOD | Poor |
| Weight(Relative) | 1.0X | 1.8x | 4.7X |
| Thermal Expansion Coefficient | 6.5*10^-6 | 23*10^-6 | 12*10^-6 |
Why Hongwo Stands Out
Our pultruded channels use a proprietary resin blend that achieves ASTM D635 Class 1 fire rating - something most competitors can’t claim. The fiberglass rails maintain dimensional stability even at 95% humidity, which we verified during 2024 monsoon testing at our Guangzhou facility.
Real-World Applications
Chemical Plants: Replaced stainless steel cable trays in a Zhejiang sulfuric acid plant (3-year ROI)
Marine Installations: Used as dock edging where saltwater destroyed aluminum in 18 months
Electrical Substations: Non-conductive properties prevent arc flashes (Hongwo’s UL-certified grade)
The Bottom Line
Whether you need FRP U Channels, composite U profiles, or fiberglass rails, Hongwo delivers 20+ year service life with zero maintenance. Our 100×50 model supports 45.6 kN/m - that’s equivalent to steel at quarter the weight. Contact our engineers today for custom lengths up to 12m.
