HSS Steel Overview and Key Characteristics
What is HSS Steel?
HSS tubing is a type of steel tubing constructed with a hollow rectangular, square, or circular cross-section. It is popular for structural applications and is responsible for almost 18% of the tubing used in the structural steel market. HSS tubing is known for its high strength and versatility.What Does HSS Stand For?
HSS tubing stands for Hollow Structural Sections tubing. These sections are engineered to provide uniform strength, consistent wall thickness, and precise dimensions.What is the Difference Between HSS and Other Types of Steel?
HSS steel tubing is a sustainable, highly efficient option with a higher strength-to-weight ratio than wide-flange sections and other structural steel, providing greater support with a smaller, lighter footprint. It is corrosion-resistant and can form smooth sides and rounded corners, making it an aesthetic choice for structural applications. HSS tubing is also highly flexible and offers a high load capacity.HSS Steel Specifications and Sizes
What ASTM Grades Are Used for HSS Steel?
We supply A500 HSS steel available to meet ASTM A500 or A1085 specifications. ASTM A500 covers standard structural tubing requirements, while ASTM A1085 provides tighter dimensional tolerances, higher yield strength, and improved performance for more demanding structural and seismic applications.What HSS Steel Sizes are Available?
HSS tubing is available in Square, Round and Rectangular sizes. Outside diameter ranges from 10” to 22”. Wall thicknesses range from .120” to 1.00”, with multiple size options available. Lengths for all shapes range from 20’ to 60’. Jumbo HSS square and rectangular tubing products are available for immediate quoting. For the full line of jumbo HSS round tubing, consult our stock list to find the size and specifications you would like quoted.What Is Jumbo HSS?
Jumbo HSS tubing sections are larger steel tubing sections, popular in commercial construction and infrastructure applications. Jumbo HSS is rated for building seismic requirements and projects that require significant fatigue support. We roll most shapes of Jumbo HSS tubing in lengths ranging from 20’ to 60’ with varying wall thicknesses for large-scale commercial projects.How Strong is HSS Steel?
