What is hollow steel section?

What is hollow steel section?

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 section used for?

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.

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 is hollow tubular sections?

Hollow Section is a type of metal profile with a hollow tubular cross section. HSS is only composed of structural steel per code. During the manufacturing process flat steel plate is gradually changed in shape to become round where the edges are presented ready to weld.

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.

What are steel sections used for?

High quality steel sections Our steel sections are suitable for use in a range of sectors and have been used to build tools, vehicles, walkways, bridges, buildings and more. We’ll provide you with hollow, structural, light and re-rolled steel sections, as well as a variety of steel processing services.

What is steel section?

Steel sections are the bread and butter of steel fabrication. Designers, architects and engineers choose different sections for their aesthetics and structural qualities – their choices determined by size, weight and profile. Steel is extremely versatile and can be moulded to many different shapes.

What is SHS and RHS?

Painted SHS (square hollow sections) and RHS (rectangular hollow sections) are high-strength cold-formed hollow steel sections that are primer painted for protection during storage and handling.

Is 4923 a material property?

Is 4923 a square pipe?

If a particular application demands corrosion resistance properties, manufacturers can elevate its resistance by surface treating the IS 4923 YST 210 with different substrates or chemicals. The usual shape of IS 4923 YST 210 / 240 / 310 Pipes is either rectangle or square.

What is a hollow structural section?

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. HSS members can be circular, square, or rectangular sections,…

What is a rectangular hollow section?

Rectangular hollow sections or rec tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel . In order to form the rectangular steel section the appropriate mother tube, a round steel tube, has to be formed first.

What is hollow square?

Definition of hollow square. : a formation of troops in former military tactics in the shape of a square with the sides each usually consisting of several ranks of soldiers and the middle holding the officers and the colors.
