High Strength Full Hard Cold Rolled Steel Coil Q195 550MPa Structural Forming
When a project needs stiffness without added weight, this high strength full hard cold rolled steel coil delivers a tensile strength of about 550 MPa through controlled cold reduction. Minimal temper rolling keeps hardness high and yield strength elevated, giving panels and profiles excellent load capacity and dent resistance at reduced thickness. The material still takes moderate bending and roll forming well, which makes it a practical choice for structural components, tubes and enclosures where cost efficiency and strength both matter. Each coil is produced to tight thickness and flatness tolerances so that downstream blanking and forming stay stable across the whole run.
Key Features
High Tensile Strength: Cold reduction raises tensile strength to roughly 550 MPa, allowing thinner gauges to carry the same structural load.
Full Hard Temper: Hardness in the HRB 85 to 95 range delivers outstanding stiffness and dent resistance for demanding components.
Good Formability Balance: Despite high strength, the coil supports moderate bending, roll forming and light drawing operations.
Lightweight Economy: Higher strength per unit thickness reduces steel consumption and lowers total material cost per finished part.
Tight Dimensional Control: Uniform thickness and flatness keep blanking, slitting and forming lines running without adjustment drift.
Reliable Supply: Regular production across Q195, Q235 and SPCC-FH grades supports repeat orders and long term programs.

Applications
Full hard high strength coils are used for structural brackets, steel furniture, shelving uprights, tube and pipe, door frames, cable trays, sign frames and construction panels. Manufacturers choose the grade when rigidity and durability must be achieved economically, since the increased strength lets them reduce thickness without sacrificing performance. It also suits roll formed sections and welded tubes that require high strength combined with reasonable forming ability.
Packaging & Quality Assurance
Coils are oiled with a rust preventive film, wrapped in anti-rust paper and packed eye to sky on steel skids with steel strapping for safe, dry ocean transport. Tensile strength, hardness, thickness and flatness are tested per lot, and a mill test certificate accompanies each shipment. Custom slitting and cut to length processing are available to match your production line requirements.
