- Section construction
- Single-skin, insulated, and composite-core sections differ in weight and structure. The chosen profile and thickness affect the door package and counterbalance requirements.
- Documentation requirements
- Permit coordination, design information, installation records, labels, component schedules, photographs, and closeout details can add project administration to the physical work.
- Operator compatibility
- The existing opener, rail, supports, door arm, reinforcement bracket, controls, and safety devices are reviewed against the completed door's weight and geometry.
