Need some sturdy square tubing for a project? This is 2-inch square steel tubing with a 0.12-inch wall thickness, cut to a 36-inch length. It's hot-rolled carbon steel that meets ASTM A36 specifications (A500/A513 grade), so it's got good strength and is easy to weld, form, and work with. It's way more common than you might think – used in everything from building frames and bridges to automotive and appliance parts. The A36 steel offers better formability than some higher-carbon steels, making it a great all-around choice for structural applications, DIY furniture, railings, or shop projects. Just remember, it's bare steel, so if you're using it outdoors, you'll want to paint or treat it to prevent rust. A reliable, versatile piece of material that won't break the bank.
