Specifications & Notes

Steel Structure Specification

Additional Notes:

  • Actual specifications may vary slightly depending on the mill; always refer to mill standards or contracts for confirmation.
  • Special applications (e.g., home appliance panels, automotive parts) may require thinner gauges (e.g., 0.25-0.4mm) or higher surface precision.
