ROLLING STEEL DOOR: SELECTION AND HANDOVER BRIEF
Yenra | Updated September 17, 2026
Guide: https://yenra.com/wiki/Rolling_steel_door/

Purpose: prepare consistent requirements for supplier quotations and record
unresolved items. Save one copy per opening. Enter "unknown" where needed;
assign a person to verify it before an order is released. Owner observations
are preliminary. Have the supplier verify dimensions and a qualified design
professional resolve mounting, structural and applicable code requirements.
This is a planning record, not installation, repair or fire-door testing instructions.

1. PROJECT AND OPENING
Building/address and jurisdiction:
Opening ID/location:
Owner/contact/date:
Reason for project (condition, traffic, security, exposure, other):
Existing door and operator model/serial numbers:
Documents/manual revisions available:
Required door family (service, insulated, fire, counter, grille):
If fire protection is required, responsible designer/authority and documentation:

State dimensions in ONE unit system (mm or inches):
Preliminary clear opening width / height:
Available headroom / side room:
Wall/support construction and mounting face:
Ceiling, pipes, cable trays or other clashes:
Floor/threshold observations:
Dimension verification by/date:
Support/attachment design by/date:

2. ACTUAL USE
Observation dates and representative shifts:
Cycle definition used (e.g. closed -> fully open -> closed):
Complete cycles/day:
Operating days/year:
Estimated cycles/year = cycles/day x operating days/year:
Busiest hour: cycles and time period:
Consecutive operation / dwell time / time held open:
Vehicles, queues and separate pedestrian access:
Expected future use changes:
Control/access method and supervision:
Alarm/dock interfaces and responsible parties:
Required power-loss arrangements to confirm with supplier:

Fictional example from guide: 80 cycles/day x 250 days/year = 20,000
cycles/year; 40 cycles in the busiest hour. Submit both daily and peak demand.
Annual cycles describe workload; they do not predict door life or warranty coverage.

3. PROPOSAL COMPARISON (repeat for each supplier)
Supplier / quotation date / validity / currency:
Exact model, size, slats, finish, operator and options:
Dimensioned drawing and mounting/support evidence:
Duty limits, cycle definition and manufacturer confirmation for our workload:
Opening/closing speed and control assumptions:
Required positive/negative wind design pressure, units and designer:
Offered rating and matching configuration/document:
Thermal value, units, method and component/whole-door scope:
Separate air-leakage evidence, if needed:
Controls/protective devices and compatibility documentation:
Fire label/listing and closing-system requirements, if applicable:
Installation, commissioning, training and acceptance responsibilities:
Maintenance schedule, parts route and service response:
Warranty scope, start date, labor and exclusions:
Supply / installation / related trade / scheduled service / callout costs:
Downtime assumptions and arrangements:
Each requirement: confirmed / excluded / awaiting verification:
Open issue -> evidence needed -> person responsible -> due date:

4. HANDOVER AND SERVICE RECORD
Installed door/operator identifiers and approved drawings:
Manuals, owner checks and technician-only tasks:
Installer commissioning/protective-device records:
Required authority sign-off:
Operating instruction and fault-reporting contact:
Service contract, next inspection and applicable fire-door test date:
Outstanding item / person / due date / closure evidence:

Repeat log entry:
Date/time / observed issue or damage / action taken / service reference /
technician findings / return-to-service record where applicable:

Do not adjust springs, tension wheels or counterbalance assemblies yourself.
Use manufacturer instructions and trained door-system service providers.
