Frequently Asked Questions (FAQ)
-
Q: What are the standard sizes available for these square tubes?
A: We offer multiple cross-sectional sizes from 1×1 inch up to 4×4 inch, with custom dimensions available upon request. Standard lengths are 6m or 12m, but we can cut to your specified length. -
Q: Can these tubes be used in outdoor applications?
A: Yes, they are UV-resistant and perform well in outdoor environments. For extended exposure, we recommend a UV-stabilized gel coat or protective coating. -
Q: What is the delivery time for a typical order?
A: For standard sizes, delivery is usually 15–25 working days after order confirmation. Custom orders may require 30–45 days depending on quantity and specifications. -
Q: Do you provide any warranty?
A: We offer a warranty against manufacturing defects for a period of 12 months from the date of shipment. Please refer to our terms and conditions for details. -
Q: Can you supply tubes with custom colors?
A: Yes, we can match RAL or Pantone colors. Custom colors require a minimum order quantity and may affect lead time. Contact our sales team for feasibility. -
Q: Are these tubes suitable for load-bearing structures like platforms or ladders?
A: Absolutely. With a 0.125-inch wall thickness, they provide good stiffness and strength for light to moderate structural loads. For heavy loads, we recommend consulting our engineers for proper sizing and reinforcement. -
Q: How do these tubes compare to stainless steel in chemical environments?
A: Pultruded fiberglass offers superior resistance to a wider range of chemicals compared to 304 or 316 stainless steel, especially against hydrochloric acids and chlorides. It is also non-magnetic and electrically insulating. -
Q: Do you offer samples before bulk orders?
A: Yes, we provide sample pieces (e.g., 30 cm length) for evaluation. Sample cost is nominal and can be refunded upon bulk order. Shipping cost is covered by the customer.
