  • 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-Liteâ„¢ commercial openings are designed for professional commercial applications where reliability, documentation, and code compliance matter.
