This HSS sizes chart lists all 525 square and rectangular hollow structural sections in the AISC Shapes Database v16.0: 126 square tubes and 399 rectangular tubes, from HSS1-1/2×1-1/2×1/8 up to HSS34x10x1. Each row gives the wall thickness, weight per foot, area and section properties.
How to Read an HSS Size
HSS8x4x3/8 is 8 in tall, 4 in wide, with a 3/8 in nominal wall. AISC designs with a reduced wall thickness, 0.93 times nominal for ASTM A500 tube, because the wall of electric-resistance-welded tube can run thin. Area and section properties below use the design wall; weight per foot is based on the nominal wall. HSS is also called structural tubing, tube steel or square tubing.

For rectangular tube, Ix and Sx are about the strong axis, bending across the taller side.
Looking for round tube? See the round steel tube sizes chart, or the stainless steel tube sizes chart for 304 and 316 tubing. For the weight of any length or a non-standard wall, use the steel tubing weight calculator.
HSS Sizes FAQ
What is the difference between HSS and square tubing?
HSS is the structural name for square, rectangular and round steel tube made to a structural standard such as ASTM A500 or A1085. Hardware stores also sell light-gauge mechanical tubing, such as 1 x 1 in 16 gauge, which is thinner and not listed by AISC.
Why is the design wall thinner than the nominal wall?
ASTM A500 allows the wall to be under the nominal thickness, so AISC uses 0.93 times nominal in calculations. Tube made to ASTM A1085 has a tighter tolerance and can use the full nominal wall.
What is the smallest HSS size?
The smallest square HSS in the AISC database is HSS1-1/2×1-1/2×1/8, weighing 2.2 lb/ft.
How much load can a steel tube carry?
Capacity depends on length, end conditions, loads and the building code, so it cannot be read from a size chart. A licensed structural engineer must size any column or beam.
