Frequently Asked Questions
Q: What makes this FRP square tube better than steel or aluminum alternatives? A: Our FRP profile offers strong corrosion resistance, is approximately 75% lighter than steel of equal cross-section, requires minimal maintenance, provides thermal and electrical insulation, and offers a longer service life in harsh environments. Q: How long will this product last in outdoor applications? A: In typical outdoor environments, our FRP square tubes have long service life with minimal UV degradation, depending on the environment. Q: Can this profile support the same loads as steel? A: While having slightly lower absolute strength than steel, the 240 × 240 × 12 mm profile can handle significant loads. When properly designed, FRP structures can meet the same load requirements as steel with appropriate safety factors. Q: What tools do I need to work with this material? A: Standard woodworking tools with carbide-tipped blades are sufficient. No welding equipment or specialized metal-working tools are required. Q: Is this product suitable for applications with temperature fluctuations? A: Yes, this profile performs reliably from -60°C to +140°C and has a lower thermal expansion rate than aluminum, making it good for applications with temperature variations. Q: How do I maintain this product? A: Simply rinse with water occasionally to remove surface contaminants. Painting, coating, or rust prevention treatments are generally not required.
