STRUCTURAL TUBING—CARBON STEEL SELECTION GUIDE

Structural tubing is relatively low in cost, has a high strength-to-weight ratio and is easily welded formed, punched and drilled.  Its hollow shape protects and conceals wires, pipes, moving parts, etc.; and it can be left exposed.

HOLLOW STRUCTURALS

hot formed, conforming to ASTM A501 (Latest)—or cold formed, conforming to ASTM 500, Grade B (Latest).  This tubing can be subjected to most of the unusual fabricating operations.  Ductility is good.  Bends well, flattens, cuts, punches, flares, flanges and welds easily.

LIGHT STRUCURAL TUBING

Electric resistance welded, and is made from low carbon 1020 strip.  The homogeneous weld is as strong as the parent metal.  Outside welding flash is removed on all sizes.  Inside welding flash is removed on all sizes.  Inside welding flash is controlled on all sizes under 2”.  This economical tubing is readily formed, bent or swaged.  It is excellent for applications where outside finish is important—for example when surface suitable for high gloss painting is needed.

HOT ROLLED BUTT WELDED

Made from low carbon, butt welded steel pipe, and has the outside welding flash removed.  One of the lowest cost square or rectangular tubes, it is suitable for a wide variety of applications where surface finish is not of primary importance.  For example, it is gaining increased acceptance as a light structural member in heavy equipment, farm machinery, etc.

Many tubes with ID less than 50% of OD or with wall more than 25% of OD, or with 1-1/4 in., or weighing more than 90lb./ft. are difficult to draw over a mandrel.  Therefore, the ID can vary over or under by an amount equal to 10% of the wall thickness.

For tubes with ID less than ½ in. (or less than 5/8 in. when the wall thickness is more than 20% of the OD), which are not commonly drawn over a mandrel the above footnote not applicable.

Tubing having a wall less than 3% of the OD cannot be straightened properly without a certain amount of distortion.  Consequently such tubes, while having an average OD and ID within the tolerances shown in this table, require an ovality tolerance ½% over and under nominal outside diameter, in addition to the tolerances indicated in this table.
