Q195 Q255 Carbon Steel Square Bar
Durable Square Cross-Section – Carbon steel square Bar features a solid square cross-section, providing excellent strength and stability for various construction and structural applications.
Reliable Manufacturing Process – Produced from steel ingots, billets, or processed steel through pressure forming, it ensures consistent quality and dependable performance.
Variety of Processing Methods – Available in both hot-rolled and cold-rolled types, square steel can meet different technical needs, whether for strength, precision, or surface quality.
Extensive Structural Applications – Widely used in light steel structures such as roof trusses, building frameworks, and civil housing skeletons, it offers versatility and practicality for modern construction projects.
Carbon steel square Bar is a solid long strip of steel with a square cross-section. Square steel is made from steel ingots, billets or steel through pressure processing. Square steel can be divided into two types: hot-rolled and cold-rolled; hot-rolled square steel refers to steel that is rolled or processed into a square section. Square steel is generally used in light steel structures, such as steel roof trusses, civil housing skeletons, etc.

Classification of carbon steel:
According to the application, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel. Carbon structural steel can be divided into building structural steel and machine-made structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (ωc≤0.25%), medium carbon steel (ωc=0.25%-0.6%) and high carbon steel (ωc>0.6%)
According to the amount of phosphorus and sulfur, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur), high-quality carbon steel (lower phosphorus and sulfur) and advanced high-quality steel (lower phosphorus and sulfur) Generally, the higher the carbon content in carbon steel, the higher the hardness and the higher the strength, but the lower the plasticity.
Carbon steel bars are widely used in machinery manufacturing, construction and bridges, ships and rail transportation, tool manufacturing
