Cold Rolling Mills and Surface Quality Control
Cold rolled steel from our mill is produced by further rolling hot rolled strip at room temperature, which gives the tight thickness tolerance, smooth surface and consistent mechanical properties that stamping and roll-forming lines depend on. The process includes pickling, cold reduction, annealing and temper rolling - each step controlled to keep the final product within specification.
For customers who feed cold rolled coil into stamping, deep drawing or PPGI coating lines, the two numbers that matter most are thickness tolerance and surface finish. Our lines hold thickness within the standard tolerance band across the coil width, and the surface is free of scale and rolling marks that would show through paint or forming.
What We Confirm Before Shipment
- Thickness profile - measured across the width, documented per coil
- Surface grade - bright or matte finish per application
- Mechanical properties - yield, tensile and hardness per heat
- Packaging - coils on steel skids with rust-preventive oil and waterproof wrapping
We can also supply cold rolled in cut-to-length sheets, which removes a processing step for fabricators and keeps the edges clean and parallel.
