Overview

Hot Rolled Squares are fundamental steel bar products essential for a vast range of general fabrication, construction, and manufacturing applications. Manufactured from low carbon steel, typically meeting ASTM A36 standards, these solid steel bars feature characteristic radius corners resulting from the hot rolling process. This production method ensures excellent overall mechanical properties, making the material exceptionally versatile and easy to work with using standard structural techniques like welding, cutting, hot forming, and machining. For businesses in Los Angeles seeking a reliable metal supply for projects involving structural supports, industrial maintenance, agricultural equipment, or ornamental ironwork, Hot Rolled Squares offer an ideal combination of strength, ductility, and cost-effectiveness. Their consistent quality and ease of fabrication make them a preferred choice for professionals working with various metal products. At our Los Angeles metal supply center, we stock a comprehensive range of sizes in ready-to-ship precut and mill lengths, and we offer custom cut-to-size services for both small and large quantity orders. Whether your project requires standard stock or specific dimensions, our inventory of Hot Rolled Squares provides a dependable solution for your structural and fabrication needs, supporting the robust construction and manufacturing industries throughout the Los Angeles area.
