Hollow structural sections with a square profile, commonly fabricated from steel or aluminum, are widely available at home improvement retailers. These materials are offered in various lengths and gauges, providing options for diverse construction and fabrication projects. For example, a 1-inch by 1-inch steel section with a 16-gauge wall thickness could be used for building a lightweight frame.
The inherent strength-to-weight ratio of this material makes it advantageous for applications requiring structural support without excessive bulk. Its uniform shape simplifies connections and joinery, contributing to efficient project timelines. Historically, this type of section has replaced solid stock in many applications, offering cost savings and reduced material consumption while maintaining adequate load-bearing capacity. Its ready availability simplifies procurement and reduces lead times for both professional contractors and DIY enthusiasts.
