Hss Tube Steel Properties

Astm 1085 table chart hss hollow structural section square structural tube.

Hss tube steel properties. Weight per foot wall thickness cross section area area moment of inertia section modulus tube radius section modulus polar moment of inertia. Steel tubing or tube steel is what we used to use in the u s. Round hss are usually astm a500 grade c fy 46 ksi. The following chart table gives cross section engineering data for steel tube pipe sizes 1 25 inches to 32 inches diameter as follows.

The tube s final dimensions. Actually i ve been asked this very question so i feel a short explanation may be necessary. To describe a closed steel section whether of rectangular square or round shape. Stee tb institute brochure.

Hss is only composed of structural steel per code. They are available in cross sections matching each of the cross sections for astm a53 grade b steel pipe. Rectangle structural tube per. Square and circular hss are very efficient shapes for this multiple axis loading as they have uniform geometry along two.

A hollow structural section or hss is the same thing as tube steel or ts right. For example an hss 6 625 0 280 has the same dimensional properties as a pipe 6 std. Hss manufacturing methods the transformation of steel strip into hollow structural sections hss is the result of a series of operations including formi ng welding and sizing. We offer round square and rectangular hss in the broadest range of sizes and gauges with a variety of value added services.

Hss members can be circular square or rectangular sections although other shapes such as elliptical are also available. Additionally astm a500 hss can be obtained in many more sizes with periphery not exceeding 64 in. Rectangular and square hss are also commonly called tube steel or box section. Our quick change technology allows us to offer the shortest cycle times in the industry.

These methods are described below. Structural tubing especially rectangular sections are commonly used in welded steel frames where members experience loading in multiple directions. Structural tube is often referred to as hollow structural sections or hss. He a steel beams properties of he a profiled steel beams modulus of rigidity shear modulus modulus of rigidity is the elasticity coefficient for shearing or torsion force radius of gyration in structural engineering radius of gyration is used to describe the distribution of cross sectional area in a column around its centroidal axis.

H height w width t wall thickness i area moment of inertia s elastic section modulus. This specification covers cold formed welded carbon steel hollow structural sections hss for welded or bolted construction.
