Steel Tube Sections
Structural tube is often referred to as hollow structural sections or hss.
Steel tube sections. Metal tubes are also commonly used as raw materials for industry. The term hollow structural sections hss refers to high strength welded steel tubing used as structural elements in buildings and other structures and a variety of manufactured products. Rectangle structural tube per.
It is produced in round square and rectangular shapes and a broad range of sizes to the astm a500 a1085 and a1065 specifications. Weight per foot wall thickness cross section area area moment of inertia section modulus tube radius section modulus polar moment of inertia. Steel tubes arcelormittal manufactures spirally welded tubular foundation piles in its mill located in dintelmond the netherlands with diameters up to 3 000 mm wall thicknesses up to 25 mm and lengths up to 53 m without butt welding.
The most common metal tube is aluminum tubing which is lightweight and resistant to corrosion. Structural tubing especially rectangular sections are commonly used in welded steel frames where members experience loading in multiple directions. Square and circular hss are very efficient shapes for this multiple axis loading as they have uniform geometry along two or more cross sectional axes and thus uniform strength characteristics.

This specification covers cold formed welded carbon steel hollow structural sections hss for welded or bolted construction. The following chart table gives cross section engineering data for steel tube pipe sizes 1 25 inches to 32 inches diameter as follows.
