Fire-Rated Insulated Access Doors

Hollow metal fire doors can be engineered with multiple insulating and structural core types depending on performance requirements. Core options include polystyrene, polyurethane, steel-stiffened, and temperature rise cores. Temperature rise and insulated cores help mitigate heat transmission across the door assembly during a fire event, ensuring life safety egress and meeting commercial building fire-rating specifications.

Doors and frames are manufactured across a range of heavy-duty thicknesses to accommodate varying traffic and structural demands. Available steel gauges range from 18 gauge up to heavy-duty 12 gauge. Material options include A60 galvannealed steel and stainless steel, providing long-term structural resilience and corrosion resistance for demanding commercial installations.

Yes, oversized door configurations are available for projects with non-standard opening dimensions. Custom hollow metal doors can be ordered in custom heights and widths while accommodating specific hardware preparations, panel layouts, and fire-rating criteria. Engineering teams work directly from submitted door schedules to verify that custom dimensions align with testing limitations and life safety requirements.

Custom orders offer flexible scheduling through dedicated quick-ship programs. Select products can ship with lead times as low as one business day, with expedited tiers ranging from one, two, three, to five days. Standard hollow metal door fabrication typically operates on a seven to ten business day schedule, allowing contractors to meet stringent inspection deadlines.

Doors manufactured under our standards include a standard one-year warranty. This warranty covers manufacturing defects and structural craftsmanship, ensuring peace of mind for distributors, installers, and facility owners. Every door is fabricated using precision CNC and laser machinery to ensure compliance with strict dimensional and structural tolerances before shipment.

Yes, custom hollow metal assemblies can be engineered to support healthcare environments. In addition to standard fire-rated life safety ratings, assemblies can be specified for medical applications including lead-lined configurations for radiation shielding. Sidelite, transom, and double egress frame assemblies are also available to meet complex hospital architectural designs.
