⚠ Compliance Matters

Many low-cost imported commercial doors sold online are not properly reinforced, lack traceable fire-label documentation, or are supplied with non-certified commercial hardware.Installing non-compliant openings can:
  • Fail commercial building inspections
  • Violate NFPA 80 fire door requirements
  • Create ADA accessibility issues
  • Lead to premature hardware failure
  • Require expensive field corrections or replacement
Steel-Lite™ commercial openings are designed for professional commercial applications where reliability, documentation, and code compliance matter.

Note: Final code compliance is determined by the complete assembly as installed in the field. Verify local AHJ requirements and approved hardware schedules prior to ordering.
