The Construction Industry and the Use of Square, Rectangular, and Round Steel Tubes

When you’re talking about the construction industry, several factors are essential: strength, resilience, and durability. Because of this, stainless steel, copper, aluminum, and carbon steel are the most commonly used materials in construction projects. With each metal having different properties and offering different strengths, they’re typically used in different applications, to achieve different goals. In today’s post, we’re going to take a closer look at these metals and discuss where, and why, they are used.

Stainless steel

One of the strongest and most resilient metals available, stainless steel has been used in the construction industry for centuries. Often used as a roofing or structural material, round steel tubing is also used for cosmetic and accessibility features such as handrails and external ornamentation.

Carbon steel

Typically utilized in structural applications, carbon steel is the go to material for construction experts looking for added hardness. Rectangular tubing made of carbon steel is often used to create frames for bridges, temporary structures and trailers.


Copper tubing is chiefly used when creating piping systems inside buildings. Whether it’s being used for water, HVAC or heating, copper’s resistance to corrosion makes it a valuable material for creating long lasting piping systems.


Aluminum’s resistance and conductive nature makes it a worthwhile material in a number of construction applications. Often used in windows, signage, lighting and doors, aluminum’s ability to withstand the elements makes it ideal for outdoor use.
