Confirm the Exact Door Configuration
Construction, finishes, insulation, glazing, hardware preparation, and available options vary by door model and order configuration.
For custom doors, confirm the approved size, handing, swing, frame details, glass configuration, hardware preparation, finish, and any project-specific requirements before production.
- Door size and configuration
- Handing and swing
- Frame and threshold requirements
- Glass or panel configuration
- Lockset, smart-lock, or hardware preparation
- Finish and color
- Project-specific thermal, impact, structural, or code requirements
Thermal, Glazing & Performance Documentation
Thermal-break, insulated glazing, Low-E, tempered-glass, and similar options must be confirmed for the specific door model and order configuration.
Do not assume that an option documented on one historical order or one profile series applies to every steel door.
Whole-door thermal, structural, wind, impact, hurricane, fire, NFRC, ASTM, AAMA, FGIA, or similar performance claims require an exact current model document before use.
Florida, Hurricane & Impact Requirements
Tempered glass by itself is not evidence of impact certification.
If a project requires Florida Product Approval, hurricane, impact, wind-load, or other regulated performance documentation, request the exact current approval or test document for the selected model before specifying or purchasing the door.
Measuring & Installation Documents
Rough-opening, anchoring, flashing, sealing, threshold, and installation requirements vary by door and wall condition.
Use the current installation document for the selected door rather than a generic installation method.
