Square and Rectangular Structural Tubing The Outside dimensions, measured across the flats at positions at least 2 in. Structural products are ordered to a specific outside dimension (OD) and “gauge” or wall thickness. Typical Mechanical Properties Round Structural Tubing: Grade A: Grade B: Grade C: Grade D: Tensile Strength, Minimum, psi Mpa 45,000 310 58,000 400 62,000 425. HSS structural tubing is most commonly produced to ASTM A500 grade B standards, but can also be available in ASTM A1085 as well. The use of HSS is growing with popularity all around the world in the building industry and in the United States. Second Moment of Area (or moment of inertia) of a Hollow Rectangle. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085. Using the structural engineering calculator located at the top of the page (simply click on the the 'show/hide calculator' button) the following properties can be calculated: Area of a Hollow Rectangle. The flat square surfaces of HSS structural tubing can ease construction, and they are sometimes preferred for architectural aesthetics in exposed structures. Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. They also have excellent resistance to torsion. In terms of tube diameters, the above formula is equivalent to: where the inner, hollow area diameter. This makes them good choices for columns. 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. Properties of Rolled-Steel (L) Shapes, Angles with Unequal Legs per. Structural Tubing, especially rectangular sections, are commonly used in welded steel frames where members experience loading in multiple directions. Structural Steel Angle Section Properties, Unequal Leg BSI BS EN 10056 Structural Steel Angle Section Properties, Equal Leg BSI BS EN 10056. Metals Aluminum is a lightweight, corrosion resistant metal commonly used as a tube material for both plumbing and construction applications. Materials include metals, plastics, and various other types. Structural tube is often referred to as hollow structural sections or HSS. Tubing material defines most of the structural and chemical properties of the tube. Standard strength requirements of the tube help dictate applications for which certain tubing is most appropriate. Structural tubing per ASTM A500 is tubing produced and used for structural applications. Dimensions and Section Properties of Rectangular HSS NOMENCLATURE Nominal width minus 3 times the design wall thickness, t (in.)
