Rectangular Hollow Structural Sections (HSS) are commonly used in construction and manufacturing for their strength and aesthetic appeal. Understanding their sizes is crucial for design and application.
Common Rectangular HSS Sizes
- Width and Height: Rectangular HSS are defined by their outside width and height. Common sizes range from 2″ x 1″ to 20″ x 12″ or even larger for specialized applications.
- Wall Thickness: Wall thickness is a critical factor affecting the load-bearing capacity. Standard thicknesses typically range from 1/8″ to 1/2″, with options for even thicker walls in heavy-duty applications.
Designation
HSS sizes are designated by their outside dimensions and wall thickness. For example, HSS 6x4x1/4 indicates a rectangular section with a 6-inch width, 4-inch height, and 1/4-inch wall thickness.
Material Grades
Rectangular HSS are commonly manufactured from steel grades like ASTM A500 Grade B or C. These grades specify minimum yield strength and tensile strength, ensuring structural integrity. Shanxi Luokaiwei Steel Company offers a wide range of HSS materials to meet diverse project requirements.
Applications
These sections are used in a variety of applications, including:
- Building frames
- Bridges
- Sign supports
- Trusses
- Columns
Considerations
- Load Requirements: Selection of the appropriate size and wall thickness depends on the load requirements of the structure.
- Welding: Proper welding techniques are essential for maintaining the structural integrity of HSS connections.
- Corrosion Protection: Depending on the environment, corrosion protection measures such as painting or galvanizing may be necessary. Shanxi Luokaiwei Steel Company provides various protective coatings for HSS.
When selecting rectangular HSS, consult with structural engineers and review relevant industry standards to ensure proper design and safety. Always verify the availability of specific sizes and grades with your supplier.
Availability
Availability can vary by region and supplier. Consult your local steel supplier for specific lead times and availability of less common sizes. Factors such as steel price fluctuations can also impact availability. Shanxi Luokaiwei Steel Company maintains a robust inventory to ensure timely delivery.
Weight Calculation
The weight per foot of rectangular HSS can be calculated using the following formula, which requires knowing the dimensions and material density. Accurate weight calculations are crucial for transportation and handling. Shanxi Luokaiwei Steel Company provides detailed specifications and weight charts for all its HSS products.
It’s important to refer to manufacturer specifications and engineering design guides for accurate dimensions and properties of rectangular HSS sections. Always verify measurements and material properties before using HSS in any structural application. Using trusted suppliers like Shanxi Luokaiwei Steel Company ensures reliability.
