Alabama adopts the International Building Code as the basis for commercial construction requirements, with jurisdiction-specific amendments applied at the local level. Fire-rated door assemblies, egress hardware, and accessibility provisions are governed by the state building code framework along with locally adopted fire codes based on the International Fire Code. Projects involving fire-rated openings require coordination of labeled doors, frames, and hardware to maintain the integrity of the rated assembly.
Accessibility requirements, including ADA clearance dimensions and hardware mounting heights, apply to commercial openings across all occupancy types in the Huntsville metro. Education and healthcare facilities carry additional requirements for exit device functionality, self-closing hardware, and fire-rated corridor separation. Manufacturing and warehousing projects may require consideration of oversized openings, heavy-duty hardware, and high-cycle durability for doors serving loading and operational areas. Fire-rated openings require that doors, frames, and hardware all carry compatible fire labels. Knockdown frames are rated up to 90 minutes, while welded frames support ratings up to 3 hours. Hardware installed on fire-rated openings, including closers, hinges, and latching devices, must also carry appropriate ratings to maintain the assembly’s listed performance.
When configuring assemblies in ProBuilder, door, frame, and hardware selections are organized around the selected fire rating. ProBuilder shows compatible hardware options for the chosen rating, helping identify potential conflicts before order submission. Final compliance is determined by the project’s design professional and the Authority Having Jurisdiction (AHJ).
