Galvanized Tube FAQs

Yes, galvanization makes tubes tougher and more durable.

No. A Round tube is able to withstand a much higher weight-per-foot than square tubing. A circle is a stronger shape than a square or rectangle due to the fact that there are no pressure points, and thus pressure gets distributed. 

Yes, but it requires a skilled welder, and may require specialized procedures.
