Iran Steel Round Bar (SBQ) / Flat Bar

Round Bar & Flat Bar

and extend their length. This process involves three roughing stages, followed by cutting the heated rebars to specific lengths using measuring shears, bypassing the ribbing stages. This efficient method ensures the production of quality rebars.
A "flat bar" or steel strap is a versatile low carbon steel product, used primarily for securing heavy loads and in construction for its high durability. Available in various sizes and materials like galvanized steel and stainless steel, it's suitable for cutting, drilling, and welding. Its applications range across industries, from securing objects in packaging to manufacturing in the household appliances, automotive, and construction sectors. Flat bars are crucial in making grating for buildings and industrial setups due to their strength and aesthetic appeal.To manufacture rebar, billets are heated in furnaces to 1100°C and then rolled to reduce their diameter
