Totten Tubes offers A500 structural steel tubing in a range of sizes and shapes. The ASTM A500 specification covers cold-formed welded and seamless
and “special” carbon steel shapes for welded, riveted, or bolted construction applications, as well as for general structural purposes.

A500 Carbon Steel Structural Tubing provides several advantageous qualities that make it a highly sought after construction material for structural load bearing applications. Some of the most recognizable beneficial qualities that A500 Carbon Steel Structural Tubing provides includes:
The ASTM A500 specifications state that manufactured carbon steel tubing must meet certain specifications before being sold for any type of project. The A 500 carbon steel spec sheet provides a convenient and simple way to check material standards before beginning your next project.
ASTM A500 spec states that welded tubing shall be made from flat-rolled steel using electric-resistance welding. Longitudinal butt joints of welded tubing shall be welded across its thickness in such a manner as to assure the structural design strength of the tubing section. Welded structural steel tubing is typically furnished without the removal of inside flash.
A500 carbon steel structural tubing is only manufactured from materials that match the criteria for carbon steel. The chemical composition for A500 is mostly iron with added carbon, manganese, phosphorus, sulfur, and copper. Check out the chart below for exact A500 carbon steel chemical specifications.

Composition, %
Element Grades A, B and D Grace C HeatTensile strength refers to the amount of stretching stress a material can withstand before breaking or failing. The ultimate tensile strength of A500 carbon steel is calculated by dividing the area of the steel by the stress placed on it, which is expressed in terms of pounds or tons per square inch of material. Tensile strength is an important measure of A500’s ability to perform in an application. A500 carbon steel’s tensile strength is described in the chart below.
Outside diameter measurements for A500 carbon steel tube must be made at positions at least 2” (50.8mm) from either end of the tubing.
For round structural tubing with nominal OD of 1.900” (48.26mm) and smaller, the outside diameter may not vary more than ±0.5%, rounded to the nearest 0.005” (0.13mm), of the specified size. For nominal ODs of 2” (50.8mm) and larger, outside diameter may not vary more than ±0.75%, rounded to the nearest 0.005”.
Square structural tubing and rectangular structural tubing must be measured across the flats and include an allowance for convexity or concavity. Specified dimensions shall not exceed the plus/minus allowances shown in the table below.
There are multiple considerations that must be accounted for when determining the outside dimensional tolerances for square and rectangular steel tubing. The chart below and the following attributes describes the exact outside dimensional tolerances for A500 carbon steel.
Outside Large Flat Dimension, in. (mm) Large Flat Dimension Tolerance, A plus and minus, in. (mm) 2½ (63.5) or under 0.020 (0.51) Over 2½ to 3½ (63.5 to 88.9), incl 0.025 (0.64) Over 3½ to 5½, inc 0.030 (0.76) Over 5½ (139.7) 0.01 times large flat dimensionTwist is measured by either holding down one end of a square/rectangular tube on a flat surface, with the bottom side of the tube parallel to the surface plate of the two corners at the opposite end of the bottom side of the tube; or, by measuring this difference on the heavier sections by a suitable measuring device. Difference in the height of the corners must not exceed the values in the table above.While A513 steel tube shares many similarities with A500 , it is significantly less durable and unsuited to heavy-duty structural assemblies. However, as it can be worked to much tighter tolerances, A513 performs considerably better for more precise projects.
