Automation adds a failure surface, not just convenience. The case for it is specific, not general.
The decision in one paragraph
Motorised blinds and Finished venetian blinds are not substitutes in the way a price list suggests. motorised blinds is specified for noise at <= 35 dB at 1 m; finished blinds is specified for ladder tape / cord at polyester, 12-25 mm. If your product depends on the first, the second is a compromise regardless of price.
Automation adds a failure surface, not only convenience. A motorised blind has a motor, a battery, a receiver and a protocol, and each can fail independently.
The case for it is specific: high windows, hotels with central control, or accessibility. Outside those, a manual blind with a good cord lock is more reliable.
Side by side on the numbers that matter
| motorised blinds | finished blinds | Comparison |
|---|---|---|
| Primary use | Hotel guest rooms | Hotel guest rooms |
| Decisive parameter | Noise: <= 35 dB at 1 m | Ladder tape / cord: polyester, 12-25 mm |
| Second parameter | Torque: 1.2-3.0 Nm | Cord lock: standard / auto-lock / cordless |
| Usual MOQ | 100-300 sets per model | 200-500 sets per size and colour |
| Production lead time | 30-45 days | 25-40 days |
| Characteristic failure | Motor stall on wide blinds | Cord lock slipping |
Where motorised blinds wins
Guest rooms and bedrooms are unforgiving above 40 dB. Must be matched to blind width and weight; undersized motors stall.
The failure you are buying protection against is motor stall on wide blinds: the blind stops halfway or hums without moving. If that is the failure your customer will report, motorised blinds is the cheaper decision even at a higher unit price.
Where finished blinds wins
Tape width affects the visual and the cord friction. The component that fails first in cheap blinds.
Against that, finished blinds fails as cord lock slipping. The blind creeps down and will not hold position. The question is whether your programme can absorb that failure, and whether the saving per unit exceeds the cost of one occurrence.
How to decide without a trial order
- Write the service conditions for the end product, including washing and climate.
- Name the failure you cannot accept, in one sentence.
- Ask both suppliers for the same test on that failure, on production material.
- Compare landed cost including the expected claim rate, not unit price.
- Record the decision and the reason, so a cheaper quote later does not reopen it.
Specifications for both are on the motorised blinds page and the finished blinds page. If you send the end product description, we will tell you which one we would specify and what we would test first.
Questions buyers ask before ordering
How many cycles will the battery really do?
300-500 on a 50 mm wooden blind, less on wide heavy blinds. We quote the tested figure and will send the cycle log; treat any figure above 600 with suspicion.
Which child-safety standard applies to my market?
EU/UK: EN 13120. US: 16 CFR 1120. Canada: CCPSA. Australia: the corded internal window coverings regulation. They are not interchangeable, and a generic certificate is not evidence.
Total cost over three years
| Line | motorised blinds | finished blinds | Note |
|---|---|---|---|
| Purchase | Higher unit price | Lower unit price | Paid at the order |
| Claims | Lower if the spec matches | Higher if the failure mode hits | Paid 6-18 months later |
| Replacement | Rare | Likely once | Paid in the season you cannot supply |
| Rework at your factory | Lower | Higher if the material behaves differently | Paid in labour |
The two materials fail in different places, and that is the deciding factor. motorised blinds fails as motor stall on wide blinds; finished blinds fails as cord lock slipping. Choose the failure you can detect early, because an early failure is a rework and a late one is a claim.
A trial that answers the question in one container
- Take production samples of both, in the exact construction you would order.
- Run the end-use process: noise, reliability, central control.
- Test the single failure you cannot accept, on both, with the same method.
- Put the result next to the landed cost including the expected claim rate.
The specification to send, for either
Whichever way you decide, send the same line to both suppliers so the quotes are comparable. For motorised blinds:
Motorised 50 mm basswood venetian blind, Li-ion battery, Zigbee 3.0, <= 32 dB, 2.0 Nm, electronic limits, manual override, 400 cycles per charge, EN 13120 safety
And for finished blinds:
50 mm basswood venetian blind, 25 mm steel headrail, branded cord lock, 5000-cycle tested, cordless with tension device to EN 13120, square within 2 mm, stain 3A, valance included
Where both appear in the same product
Most assembled products use both materials rather than choosing one. motorised blinds typically carries hotel guest rooms, while finished blinds carries hotel guest rooms. The decision is therefore not which one to buy but which one to put where the load and the wear are.
A practical rule: put motorised blinds at the point where motor stall on wide blinds would be expensive to fix, and finished blinds where cord lock slipping is visible early enough to rework. That single sentence resolves most specification arguments between the two.
Three questions to ask both suppliers
- Which parameter would you change to hit a lower price, and what does it cost? The answer shows whether the supplier understands their own trade-offs.
- What is the MOQ per colour, and what does a repeat order need? motorised blinds typically runs 100-300 sets per model; finished blinds runs 200-500 sets per size and colour.
- What would you refuse to guarantee, and why? A supplier with no limits is either new or not answering.
Seven lines that turn a quotation into a specification
Most post-delivery arguments are not about quality. They are about a document that never said which figure would be measured, on which instrument, at whose cost.
- Manual override: the figure you will accept inside the required band, the tolerance on it, and the method used to measure it.
- Power (Li-ion battery / 12 V DC / hardwired): name the number, not the word. If the answer only repeats the band, ask which point inside it is being offered for this order.
- Protocol: RF 433 / Zigbee / WiFi / Matter / Z-Wave is the market band. Fix the figure you will test at goods-in, and the instrument you will test it with.
- Noise (<= 35 dB at 1 m): fix the value per shipment, and state who pays for the re-test if a lot lands outside it.
- Price validity: the period during which the quoted figure holds, and what happens to it when the raw-material index moves.
- Remedy: rework, replacement or credit, and the point at which each applies.
- Sample retention: one production sample per lot stays with the mill for twelve months. Claims are settled against it, not against memory.
Three questions, and the answers that separate mills
If the comparison you are making is going to be decided on a call, take these three questions into it.
| Question | Answer that should worry you | Answer that holds up |
|---|---|---|
| Which test catches motor stall on wide blinds? | “We have never had a complaint.” | Torque and current — on the production lot, with the acceptance figure written into the report and not into the email. |
| May I see a report for a lot you shipped last month? | “That is confidential customer information.” | A redacted report, which carries every number that matters and none of the customer’s identity. |
| Where in the Li-ion battery / 12 V DC / hardwired band will this order sit? | “In the middle, normally.” | A stated target and the readings behind it. Power drifting inside the band is how a conforming lot still fails. |
Choosing between these two for a live programme?
Send a window schedule or a single set size and we will return a quotation with the loading plan, the safety standard that applies to your market and the lead time for the colour you need. Catalogue and current price list on request.
