How do you read HSS sizes?
HSS are available in round, square, or rectangular shapes. Round shapes are specified using decimal numbers and three decimal points. For example, HSS 5.563 × 0.258 indicates a round HSS with an outside diameter of 5.563” and a wall thickness of 0.258”.
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.
What lengths does HSS come in?
Atlas Tube is North America’s exclusive provider of steel hollow structural sections (HSS) in sizes ranging from 18″ to 22″ square. Jumbo HSS meet ASTM A500 and CSA G40. 21 standards.
What does HSS stand for in steel?
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 is the radius of HSS?
For HSS produced to ASTM A500, the radii are based on the design wall thickness, taken equal to 90% of the nominal value. The maximum exterior corner radius permitted by the G40. 20 standard varies from two to four times the wall thickness, depending on the section perimeter and wall thickness.
What is a HSS steel shape?
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.
What is an HSS beam used for?
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 grade is HSS steel?
A500 grade C
Today, HSS is commonly available in mild steel, A500 grade C. Other steel grades available for HSS are A847 (weathering steel), A1065 (large sections up to 50 inch sq made with SAW process), and recently approved A1085 (higher strength, tighter tolerances than A500).
What is the difference between A500 and A513?
The reporting of physical properties is one of the major differences between A500 and A513 material….Product Showdown: A500 vs A513.
| A500 | A513 |
|---|---|
| Looser Dimensional Tolerances (ex: 2×2-.083, Corner Radius max is .249”) | Tighter Dimensional Tolerances (ex: 2×2-.083, Corner Radius is 5/64” to .125”) |
What size does box steel come in?
Rectangular hollow section sizes start from 50mm x 30mm and 3.2mm thick, although some larger sizes can be specified at 3.0mm thick. Our largest standard size for rectangular steel box sections is 500mm x 300mm and 20.0mm thick.
How hard is HSS steel?
The alloying elements raise the temperature at which tempering occurs, allowing HSS to be used at temperatures up to about 650°C. Their hardness is limited to 750 HV, adequate for machining most of the common metals, including alloy steels in their unhardened forms.
Can you bend HSS?
Curved steel hollow sections are widely used in the construction industry. The possible curvature of these members, however, is limited by the magnitude of distortion of the cross‐section during the bending process.
