![]() ![]() Structural Beams come in various shapes and sizes so it is important to use the correct terminology when measuring. HSS Tube is commonly specified using the outside size measurements and the tube wall thickness (square tube example: 2.000” x 2.000″ x 0.250” wall / round tube example: 3.000” Dia. Particularly well suited for compression column applications.Easier in fitting mating parts together (no notching).High resistance to torsional loading (excellent choice for bracing).A high strength-to-weight ratio (less weight-per-foot).They are available in a broad range of sizes and gauges. HSS Tubes are produced in three shapes – round, square and rectangular. It is also used to a great extent in the fabrication of enclosures, automobiles and many other structural applications. Hollow Structural Steel (HSS) Tubing has become an essential component of the construction industry. Wall Thickness: The thickness of the tube wall (“B”). Outside Diameter: The measurement of the outer diameter of the tube (see “A” in the diagram below). Wall Thickness: The thickness of the tube wall (“C”). Outside Dimensions: The outer measurement of each side (see “A & B” in the diagrams below). Hollow Structural Steel Tube HSS Rectangular Tube and Square Tube Terms Dimensions in North America are typically in inches and in the UK, millimeters. The size measurement of structural angle is commonly specified using the length of each leg (flange) and the thickness of the leg (flange). Legs (or flanges) that are differently sized are typically known as unequal leg angle. This item can have equal sized legs (or flanges) this is typically known as equal leg angle. It is ideal for all structural applications, general fabrication and repairs. It is a piece of structural iron or steel in the form of a 90 degree angle. Structural Angle is a steel bar that has an L-shaped cross section. The radius of the fillet is called the fillet radius (not always provided) Other terms: Fillet radius: The curved portion, where the inside transition between the web and flange occurs is called a fillet. Leg (Flange) Thickness: The thickness of the leg (“C”). Leg (Flange) Size: The measurement of each leg (see “A & B” in diagram). Structural Steel is an important building material characterized by its shape and cross-section, as well as its mechanical and chemical qualities.
