Mild Steel Coils

Industrial Durable Hot Rolled Coils

Manufacturing Process: Steel slabs are heated to over 1,700F (930C) and passed through heavy rollers to achieve the desired thickness.Mechanical Properties: The high-temperature rolling process aligns the steel's grain structure, resulting in excellent toughness, ductility, and resistance to deformation under heavy loads.Surface Finish: Because the steel cools in the open air, it develops a slightly rough, scaled surface. For applications requiring a smoother finish, these coils often undergo pickling and oiling (HRPO).Cost-Effectiveness: The simplified manufacturing process (compared to cold-rolled steel) makes HR coils an economical choice for large-scale production

Precision HR Coils

Material and Grades: Commonly made from carbon steel, including SPHC, SPHD, Q195, and Q235 grades, which are ideal for forming.Dimensional Accuracy: Precision rolling and slitting techniques ensure uniform width and thickness tolerances, crucial for modern manufacturing.Performance: High-performance characteristics include high tensile strength (often 250 to 600 MPa) and strong resistance to deformation.Physical Properties: Excellent weldability for fabrication, with high durability for long-term usage in harsh environments.Surface: Often available in standard "black" (with mill scale) or pickled and oiled (HRPO) for a smoother, cleaner finish

Mild Steel Rolled Coil

Durable HR Coils

A durable HR (Hot Rolled) coil is a highly versatile, heavy-duty steel product manufactured by rolling steel at extremely high temperatures (typically above 1700F). This heating and rolling process aligns the steel's grain structure to deliver exceptional tensile strength and rugged durability.Key Characteristics & BenefitsInherent Strength: Capable of withstanding extreme mechanical strain and harsh industrial environments.High Formability: The elevated temperatures allow the steel to be easily shaped and molded without cracking.Cost-Efficiency: Because it requires fewer finishing steps than cold-rolled steel, it is a highly economical material for large-scale projects.Visual Profile: Typically has a dark grey or bluish, rugged surface with slight mill scale

Mild Steel HR Coils

Manufacturing Process: Rolled above the steel™s recrystallization temperature, making the material easy to shape, cut, and bend without breaking.Surface Finish: Features a characteristic "mill scale" (a rough, dark, oxidized surface layer). They can also be purchased pickled and oiled (P&O) to remove the scale for a smoother finish.Thickness & Dimensions: Typically available in thicknesses ranging from \(0.5 \text{ mm}\) to \(25 \text{ mm}\) and widths varying between \(1,000 \text{ mm}\) and \(1,500 \text{ mm}\).Mechanical Properties: They are highly ductile and virtually free of internal stresses since they cool at room temperature.
