Demension

Hollow Section Shape (HSS)	Outer Diameter	Wall Thickness
Square and rectangular tubing	1.0 – 16 in [25 – 405 mm]	0.095 – 1.0 in [2.5 – 25 mm]
Round tubing	1.0 – 48 in [25 – 1220 mm]	0.095 – 4.0 in [2.5 – 100 mm]

Chemical Composition

Composition, %	Grade A		Grade B and Grade C
Composition, %	Heat Analysis	Product Analysis	Heat Analysis	Product Analysis
Carbon, max ^B	0.26	0.30	0.22	0.26
Manganese, max^B	-	-	1.40	1.45
Phosphorus, max	0.035	0.045	0.030	0.040
Sulfur, max	0.035	0.045	0.020	0.030
Copper, min (when copper steel is specified)	0.20	0.18	0.20	0.18

B For each reduction of 0.01 percentage point below the specified maximum for carbon, an increase of 0.06 percentage point above the specified maximum for manganese is permitted, up to a maximum of 1.60 % by heat analysis and 1.65 % by-product analysis.

Demension Tolerance

A501: Hot-rolled forming, looser composition requirements, fewer strength grades (A/B/C), lower cost, suitable for general structures.
A500: Cold-formed, stricter control of mechanical properties, more strength grades (A/B/C/D), better formability, suitable for precision / high-demand structures.
Applicant Field：

Building Structures: Factory buildings, high-rise buildings, bridges, trusses, columns and beams, supports.
Machinery and Equipment: Conveyor frames, steel structure platforms, vehicle chassis, construction machinery.
Piping and Engineering: General fluid transportation, municipal engineering, non-high-pressure structural pipelines.
Others: Shelving, guardrails, steel structural components, welded / riveted / bolted connection structures.
