Frequently Asked Questions
What gauge steel should I specify for industrial doors?
For most manufacturing and warehouse applications, 16 gauge (HMMA Level 3) provides excellent durability and impact resistance. Areas with forklift traffic or potential for severe abuse should use 14 gauge (Level 4). Light industrial or warehouse storage areas can use 18 gauge (Level 2). For extreme abuse or blast resistance, 12 gauge is available.
What fire ratings are available for industrial doors?
Industrial metal doors are available with fire ratings from 20 minutes to 3 hours, certified by UL, WHI, and FM. Steel-stiffened or mineral cores are required for ratings above 45 minutes. Fire-rated assemblies include matching frames and listed hardware. Consult NFPA and local codes for specific requirements based on occupancy and hazard classification.
Are industrial doors suitable for forklift traffic areas?
Yes, with proper specification. Use 14 gauge minimum (16 gauge for lighter traffic) with steel-stiffened core. Continuous geared hinges distribute stress better than butt hinges. Heavy-duty closers with backcheck prevent wall damage. Consider protective accessories like bumpers and edge guards. Galvanized steel provides corrosion resistance if moisture is present.
What core type is best for industrial applications?
Steel-stiffened core is the standard for industrial applications, providing excellent impact resistance and fire ratings up to 3 hours. Mineral core offers superior acoustic performance (STC 40-45) in addition to fire rating. For temperature-controlled areas like cold storage, polyurethane core provides thermal insulation (R-12 to R-15).
How do I specify doors for chemical or corrosive environments?
For chemical exposure, specify galvanized steel with chemical-resistant epoxy coating, or stainless steel (304 or 316 grade) for severe environments. Ensure all hardware is also corrosion-resistant - stainless steel hardware is recommended. For food processing or pharmaceutical, FDA-compliant coatings on galvanized or stainless steel provide both corrosion resistance and regulatory compliance.
What hardware is recommended for industrial doors?
Industrial doors require heavy-duty hardware: continuous geared hinges for high-cycle or heavy doors, industrial-grade closers rated for door weight, and commercial/industrial locksets. For high-frequency use, specify 1,000,000+ cycle components. Stainless steel or galvanized hardware provides corrosion resistance. Industrial applications often need larger backsets and heavier strikes.
How do I maintain industrial metal doors?
Monthly inspection of hardware operation and visual check for damage. Lubricate hinges and pivots quarterly. Annual detailed inspection per NFPA 80 for fire-rated doors. Touch up coating damage promptly to prevent corrosion. Replace worn weatherstripping. Tighten or replace hardware showing wear. Keep tracks and thresholds clear of debris.
What is the lead time for industrial doors?
Standard industrial door configurations typically ship in 4-5 weeks. Custom sizes, heavy gauges (14 or 12), or special coatings require 6-8 weeks. Large projects or unusual specifications may require additional time. Contact us with project details for accurate lead times.
