Square steel is a very strong solid steel bar with excellent strength and cold resistance. Due to its high strength and versatility, square steel is widely used in the construction and fencing industry, most often in commercial and residential buildings, light steel structures, steel roof trusses, but also in gratings, hinges, handles, tracks and railways.
The hot rolling process of square steel makes the metal easier to form and produces larger dimensions. Hot rolling is usually cheaper than cold rolling because it can become a finished product without time delay. Conversely, the cold rolling process can increase the strength of the finished product by up to 20% while creating a smooth grey finish.
Cold formed 1018 square steel
Cold-formed 1018 square steel is a widely used cold-drawn low-carbon steel with tight dimensional accuracy, smooth surface finish, good surface hardening properties, and improved mechanical properties and machinability, especially for cold forming and bending.
Hot formed A36 square steel
A36 square steel is a hot rolled mild steel solid bar ideal for all structural applications, general fabrication, fabrication and repair. This steel shape is easy to weld, cut, form and machine and is widely used in industrial maintenance, farm implements, transportation equipment, decorative ironwork, fences, artwork and more.
Features of hot formed A36 square steel:
1. Slightly rounded edges and corners (due to shrinkage) 2. Slightly twisted, possibly slightly trapezoidal shape rather than perfectly square corners 3. Rough surface
