Square Tube Bending

Depending on the outside dimensions, wall thickness and radius, square tube can be rolled or bent in countless ways. And being symmetrical helps.  Square tubing can be rolled off-axis as in the case of the Kimmel Center  where the 5 square tubing is curved 45 degrees off-axis.

With the proper machine, operator and tooling, square tubing can be bent to a surprisingly tight minimum radius successfully even if the wall of the tubing is thin.  For example, Chicago Metal Rolled Products can bend an 8 x 8 x ¼ square tube to a 12ft. inside radius--a tight curve for a large, thin-wall tube.

The demand for metal tube rolling that is square has increased.

Square Tube Bending Applications

Bent square tube is used in OEM applications like roll-over protection, framework, bumpers, and playground equipment. All kinds of structures now are built with square tubes that are bent: roofs, trellises, canopies, arches, balconies, and portals. Square tubing can be formed into a helix.  This application is most often used to create stair stringers for circular staircases

  • "Without CMRP able to roll these channels to my specifications, there was no way this beautiful round antenna would have ever worked.
