Select hollow metal doors and frames to the correct ANSI/SDI A250 series standards for a given commercial duty level.

Steps

1. Determine the required duty level for the opening (heavy commercial traffic vs. light duty) and select door/frame gauge and construction referencing the general product standard for standard steel doors and frames.
2. Confirm the door/frame combination has documentation of physical endurance testing where high-cycle durability is required for the project.
3. Specify hardware reinforcement matching the actual hardware schedule (closers, exit devices, electrified hardware) so mortar/reinforcing plates are correctly located before fabrication.
4. Check finish requirements against the applicable factory-applied-finish or prime-paint acceptance standard depending on the specified finish system.
5. Reference SDI's current published document list to confirm which edition of each A250-series standard is current at time of specification, since these are revised periodically.
