Steel door making in Kenya: Operations and Quality Checks
Deliver the agreed result consistently
Specify the door, frame and hardware as one compatible assembly, checking handing and intended access before fabricating a steel leaf from a customer's rough dimensions.
The operating sequence for this offer is:
- Measure the doorway and record opening direction, existing frame condition and access needs before specifying the proposed steel door assembly.
- Approve sheet, frame, lock and finish details, then fabricate through a competent workshop and document any changed dimensions.
- Check alignment, closing and locking with the client; retain the hardware specification without inventing fire-resistance or burglary ratings.
Put acceptance into the job record
Door closes, locks and aligns consistently with the approved assembly.
Inspect operation, closing and finish with the buyer after fitting, checking the approved hardware and explicitly separating product workmanship from unsupported claims about intrusion resistance.
Inspect at the point where a correction is still possible, then again at handover. Record rejected or incomplete output separately from accepted output. A completed task is not automatically an accepted task, and an invoice does not establish that the customer received the right result.
Measure real capacity
Time preparation, the main operation, transport, cleaning, approvals and correction as applicable. The slowest stage determines how much you can promise. Where two orders need the same person, space or equipment at the same time, resolve the conflict before confirming both deadlines. An additional enquiry should not erase a commitment already made.
| Operating checkpoint | Evidence for this business |
|---|---|
| Before starting | Specify the door, frame and hardware as one compatible assembly, checking handing and intended access before fabricating a steel leaf from a customer's rough dimensions. |
| During delivery | Approve sheet, frame, lock and finish details, then fabricate through a competent workshop and document any changed dimensions. |
| At acceptance | Inspect operation, closing and finish with the buyer after fitting, checking the approved hardware and explicitly separating product workmanship from unsupported claims about intrusion resistance. |
| At the pilot review | Record opening measurements, hardware references, frame alignment and closing adjustments, building a repeatable handover checklist before accepting multiple doors for a landlord or small development. |
Keep a correction and escalation rule
When inputs, access, specifications or customer instructions change, pause the affected work and confirm the effect on time and cost. Do not quietly lower the acceptance standard to avoid a delayed delivery. Keep rework caused by your error distinct from a customer-requested change of scope and agree the remedy clearly.
The fabricated leaf is sound but the frame distorts during fitting, producing difficult locking and repeat visits because installation sequencing received less attention than welding appearance.
Retain the minimum records needed to investigate a complaint without disclosing unrelated personal information. Use measured delivery and actual acceptance as the basis for expanding capacity, rather than the maximum theoretical output of a tool or production line.
Operating control points for this exact offer
| Sequence | Work method | Release checkpoint |
|---|---|---|
| 1 | Measure opening, diagonals, wall and floor finishes and required swing/exit function. | Do not cut from a single nominal doorway size. |
| 2 | Approve fabrication drawing and hardware/clearance plan with competent designer/installer. | Any security or fire rating requires actual complete-system evidence, not sheet thickness claims. |
| 3 | Fabricator prepares traceable specified sheet/sections and workshop fixtures. | Check steel identity and actual dimensions against takeoff. |
| 4 | Qualified personnel fabricate, inspect joints/flatness and apply supported finish, controlling heat distortion. | A twisted leaf is not forced into a crooked frame to appear closed. |
| 5 | Installer fits the specified support and demonstrates ordinary opening, latching and exit. | Keys, hardware record and use limits are handed to owner. |
Do not substitute a tick for an observation: record the count, measurement, approved sample or evidence reference used at each checkpoint. Mark unresolved work as held and identify who can approve the recheck.
Diagnose a failure before repeating it
| Observed symptom to investigate | Check the cause | Proposed response |
|---|---|---|
| Leaf twists after fabrication | Compare flatness and heat-control inspection before coating. | Have the fabricator correct or remake to the approved criteria. |
| Door catches the threshold | Check finished floor height and frame alignment. | Resolve the measured installation issue rather than forcing the lock shut. |
| Customer expects a certified fire door | Compare quoted non-rated scope with requested duty. | Obtain a compliant complete-system specialist quote; do not relabel this door. |
These are diagnostic prompts, not proof of the cause in a real incident. Separate suspect output, record any correction and repeat the relevant acceptance check. Link rejected units, rework time, replacement materials, customer credits and collection delays to the actual job result.
