Hexagon and Octagon Tube, Too.
Square, rectangular and round are what the mills run every day, but they are not all they can make. On special request we form hexagon and octagon tube, for handles, posts, shafts and parts that need flats to grip, index or keep from turning.
Send the size across the flats, the wall, the length and the footage, and we will quote it.
Choosing a Tube.
Start from the shape and size, then the specification, then the length and bundles. The finish follows from where the part goes, and is covered under Finishes and Specs.
Shape and Size
Square and rectangular tube welds flat to flat and suits frames; a rectangle on edge is stiffest. Round tube is equally stiff in every direction and suits rails, posts and axles. The size and wall follow the load. Section Properties
