Galvanized Square Tube Pipe

Galvanized square tube pipes are commonly used in construction, infrastructure, and industrial applications. They are particularly useful for applications requiring structural strength, such as support frames, posts, handrails, fences, and outdoor structures. The square shape provides additional stability and load-bearing capacity compared to round pipes.
