Buying Guide: Key Purchase Considerations
- Fire rating and placement: Verify wall vs. floor-to-ceiling requirements, and ensure the rating aligns with code demands for your building type (schools, hospitals, offices, etc.).
- Material and insulation: Look for double steel or solid galvanneal steel, plus mineral wool insulation to slow heat transfer and maintain structural integrity during a fire.
- Finish and durability: Choose primed or baked-on enamel finishes that resist UV exposure, salt spray, and corrosion for long-term performance in challenging environments.
- Size and opening: Confirm Rough Opening dimensions and maximum opening sizes allowed by fire regulations; ensure the door fits the intended crawl space, utility, or access corridor.
- Hardware compatibility: Check latching mechanisms, lock-key options, and whether master-keying is required for security in shared facilities.
- Automation and closure: Consider automatic closers to maintain fire resistance post-use and to comply with passive fire protection requirements.
- Maintenance and accessibility: Ensure the door is easy to operate, latches securely, and provides reliable access for maintenance teams without compromising fire safety.
- Code compliance: Confirm certifications (UL, NFPA, CAN/ULC) and confirm compatibility with local fire codes and institutional guidelines.
