Hollow Structural Sections, or HSS, are cold-formed, welded steel tubes used for welded or bolted construction of buildings, bridges, and other structures as well as a wide-range of manufactured products. They are produced in square, round, and rectangular shapes to meet structural design requirements.

What is hollow steel structure?

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. It is produced in round, square and rectangular shapes and a broad range of sizes to the ASTM A500, A1085, and A1065 specifications.

What does HSS mean on structural drawings?

Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085.

Where are hollow sections used?

For example, hollow sections have been used in iconic structures such as the London Eye, Emirates Stadium and space- frame structure of the world record-breaking JCB Dieselmax. Also, they are ideal for everyday applications such as vehicle trailers, fences and handrails.

What are hollow sections?

A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. Rectangular and square HSS are also commonly called tube steel or box section.

What is hollow tube?

A hollow tube is mounted on the burner and the light path passes along the length of the tube. Samples are nebulized and atoms enter the tube where they are prevented from dispersing throughout and beyond the flame by the physical presence of the tube.

How are steel hollow sections made?

There are two basic methods of producing hollow sections – the seamless process in which a hole is pierced through a hot solid bar to form the bore and then the bar is rolled to form the round tube, and the welded process in which a steel plate or strip is formed into a cylindrical shape and the edges welded together.

What does TS mean in structural steel?

Steel tubing, or tube steel, is what we used to use in the U.S. to describe a closed steel section — whether of rectangular, square or round shape.

Why are hollow pipes used in construction?

Hollow section pipes have excellent resistance to torsion so as to be widely used as the efficient structural materials in constructions today. Rectangular steel pipe is one popular member of hollow section pipes which are metal profiles with square or rectangular tube section.

Is code for hollow sections?

4.1 General requirements relating to the supply of steel hollow sections shall conform to IS 1387. 7.1 For the purpose of the standard, the weights are calculated on the basis that steel weighs 0.785 kg/cm* per metre run.
