How to choose the right product
Start from the performance requirement written into your project's specification:
- Escape route requiring outward-opening, hinged access → Escape doors
- Fire compartment requiring a hinged fire-rated door → Fire doors
- Wide fire compartment opening, or an opening where a swing door isn't practical → Sliding fire doors
- X-ray, CT or other diagnostic room requiring radiation shielding → Lead-lined doors
- Forced-entry or ballistic-resistant opening → Security doors
- Electrical substation or transformer room requiring security and ventilation together → Transformer room doors
If your project needs several of these at once — a fire-rated door in a healthcare corridor, for example — see Solutions for how Alpha combines requirements at specification stage, or Industries for the sector-specific view.
