Structural Steel Square Tube vs. Mechanical Steel Square Tube

While mechanical steel tube and structural steel tubing share many similarities, they are each suited to different industries and applications.
Mechanical steel square tube is produced to strict tolerances and specifications for high-precision projects in light-gauge applications. It is used in practically every industry, from automotive to machinery to agriculture. Structural square tubing is strong and durable. However, it tends to have less precise requirements and tolerances. Structural tubing is used in high-stress and long-term applications such as construction, signposts, and infrastructure.
If you are unsure if mechanical tubing or structural tubing is best for your application, contact us. Competitive Metals is your top supplier of metal products and knowledge. We’ll help you navigate our inventory to find the best metal for your planned use.
