To distinguish reliable manufacturers from others, here are key criteria:
- Certifications & Testing
Doors should be tested by recognized labs (e.g., CBRI Roorkee, or other internationally accredited labs) for integrity, insulation, stability. The manufacturer should produce test reports.
Sehgal Doors, for example, is known to manufacture CBRI-approved fire doors. - Range of Fire Ratings
A credible manufacturer should offer various ratings like FD 30, 60, 90, 120 minutes depending on the building requirement. - Material & Design Versatility
Steel (hollow metal), solid wood, composite wood, glazed (fire rated glass) doors, and hybrid options provide flexibility for architectural needs. - Use of Quality Components & Hardware
Intumescent seals, fire-rated glass, certified hinges, panic bars, self-closers, frames, and finishing are vital parts of the system. - Installation Expertise & After-Sales Support
Proper installation (alignment, sealing, fire stops) is as important as the door itself. Maintenance and periodic checks are essential. - Compliance with Indian Regulations & Building Codes
The National Building Code (NBC) of India outlines requirements under its Fire & Life Safety section. Manufacturers must help clients comply. - Track Record & Project References
Experience in institutional, commercial, residential, and industrial projects builds trust.
