Purlins are the ultimate solution for anyone looking to build strong, reliable roofing or framing systems. Perfect for DIYers and contractors alike, these lightweight yet durable steel beams provide excellent support for roofing panels, walls, and other structural elements. Easy to handle and install, purlins are designed to simplify your project while ensuring professional-grade results that stand the test of time. Whether you’re constructing a shed, carport, barn, or even a larger building, purlins deliver unmatched strength and versatility to keep your project standing tall.

Cee purlins feature a light red oxide coating designed to provide temporary rust protection during shipping. Please note, this coating is not a final finish but rather a primer applied over bare steel, not a galvanized surface. The red primer helps prepare the metal for an additional topcoat of paint. For best results, we recommend painting red purlins before installation. Without a secondary paint finish, the purlins may be prone to rust.

Square Stock

Square stock is the go-to material for DIYers and contractors who need versatility and strength in one package. With its uniform square cross-section, this structural steel is perfect for building frames, braces, furniture, and custom projects that demand durability and style. Easy to cut, weld, and shape, square stock makes it simple to create professional-grade results without the hassle. Whether you’re working on a home renovation, a piece of custom furniture, or a heavy-duty build, square stock is the trusted choice to turn your vision into reality with strength that lasts.

Square Steel Tube is a versatile, welded structural-grade tubing available in type A513, depending on size and wall thickness. It is perfect for structural applications, fabrication projects, manufacturing, and repairs. Commonly used in industrial maintenance, agricultural equipment, transportation, truck beds, trailers, and frames. Its box-shaped design offers superior strength and rigidity compared to angles or channels. This steel tubing is easy to cut, weld, shape, and machine with the right tools and expertise, making it a go-to choice for a wide range of projects. If you are unsure if our A513 square steel tubing will work for your project, please contact your engineer or designer.
