At Totten Tubes, we aim to meet the needs of clients in every industry. To that end, we offer square steel tubing in structural and mechanical grades. Our broad selection includes tubes in sizes from 3/8” x 3/8” up to 20” x 20”.

Structural Steel Tubing

Structural steel tubing can be used for a broad range of static applications.

At Totten Tubes, we offer square steel tubing for all types of structural applications.

For more information about the structural steel tubing that we offer, please view the a500 spec sheet.

Whatever your mechanical application, we have the square steel tubing that you need.
