How Supply-Only Trade Aluminium Fabrication Works — and Why We Never Install
This is the plain-English explainer of the model Kingsland Fabrications runs on. We supply and fabricate aluminium. We do not install. Our customers are the people who do: installers, fitters, shopfitters, glaziers, main contractors and reactive door-maintenance firms.
If you have ever wondered what "supply-only" actually buys you, where a fabricator's job ends and yours begins, or why a fabricator that never fits is a safer partner than one who does — this page answers it.
What "supply-only" and "trade-only" actually mean
A supply-only aluminium fabricator manufactures the doors, windows, shopfronts, curtain walling and louvre panels — and stops there. We cut, machine, assemble, test and deliver a complete kit ready to fit. We never send a fitting team to site. The installation is carried out by you, our trade customer.
Trade-only is the other half of the same coin: we sell to businesses in the supply chain, never to homeowners or end users. You will not find a member of the public buying a doorset from us, and you will not find us pricing a job for the building owner directly. We quote the buyer, fabricate to the buyer's spec, and deliver to the buyer.
Compare that with a fabricator-installer — a full-service outfit that both makes the product and fits it. Plenty of those exist, and for a homeowner ringing round for "new shopfront doors" they can be a one-stop shop. But for a trade buyer, a fabricator-installer is a supplier who also operates in your market. That distinction is the whole point of this page, and we come back to it below.
In one line: we make it and verify it; you fit it and own the customer. No part of our model competes with yours.
The end-to-end workflow
Every order runs the same chain, from your first email to your fitter on site. Note exactly where step 8 ends and step 9 begins — that boundary is the supply-only model in practice.
Enquiry
You send sizes, quantities, a survey, drawings or a sketch with a delivery postcode. Trade only — we deal with the buyer, not the end client.
24-hour quote + CAD
We return a trade quote inside 24 hours, with CAD drawings for sign-off where the job needs them. The drawing is the contract: what you approve is what gets cut.
Engineering
Confirmed dimensions are engineered in LogiKal® and EluCAD®, turning the approved drawing into a cutting and machining programme.
CNC cut & punch
Profiles are cut and punched on Elumatec CNC machinery against that programme — not by hand, not by eye.
Fabrication
Sections are assembled on Jack Aluminium and compatible system platforms into doors, windows, shopfronts, curtain walling or louvre panels.
Jig-test
Every unit is stood in a jig frame and checked against your signed dimensions and hardware schedule before it leaves Warrington. Our target is a 99% first-time fit rate.
Palletised kit, labelled
The kit is wrapped complete — beads, gaskets and fixings in the box — and labelled by opening reference so site handling is straightforward.
Delivered across mainland Britain
Pallets go out from Warrington to anywhere in mainland Britain. That is where our responsibility ends.
You fit and commission
Your fitter offers the kit into the opening, fixes it, glazes where supplied loose, sets the hardware and commissions on site. The install is yours — and the relationship with the end client stays yours too.
Where our responsibility ends — precisely
Our responsibility covers everything up to and including a complete, jig-tested kit delivered palletised to your nominated address: correct dimensions against the signed CAD, the right hardware schedule, beads, gaskets and fixings in the box, and clear opening-reference labelling.
Your responsibility starts at the pallet: site survey accuracy, structural opening, fixings into the substrate, levelling and packing, on-site glazing where supplied loose, commissioning of closers, locks and operators, weatherproofing the perimeter, and handover to the end client. If a unit reaches site genuinely wrong against the signed drawing, that is on us and we remake it. If the opening on site differs from the survey we were given, that is a survey issue — and we would rather catch it at CAD sign-off than after manufacture.

Why never installing is the point, not a limitation
When a fabricator also installs, they are in your market. They quote fits. They hold service contracts. They talk directly to the building owners and facilities managers you are trying to win and keep. Every drawing you hand them is competitive intelligence — your sizes, your client, your scope — going to a business that fits the same work you do.
Most fabricator-installers are perfectly honest. But the structural conflict does not go away because everyone means well. The day their direct-install diary is quiet, your enquiry is a lead they could take themselves. The day an end client you introduced asks them for a maintenance contract, they are conflicted by design.
Because we never install, none of that exists. We cannot take the fit, because we do not fit. We cannot take the service contract, because we do not service. We cannot take your end client, because we never meet them. The only thing we sell is fabrication, to you. Your install, your margin, your relationship and your repeat work all stay yours.
That is why supply-only neutrality is a feature, not a gap. It is the reason a contractor can hand us a full schedule for a flagship job without wondering whether the supplier is sizing up the client. We deliberately stay on one side of the line so you never have to ask the question.
Who it's for — and what lands on the pallet
Who buys this way
- • Aluminium and glazing installers running new-build and refurb programmes
- • Shopfitters and fit-out contractors needing coordinated shopfront packages
- • Glaziers replacing failed commercial doors and screens
- • Main contractors buying curtain walling and entrance packages to fit with their own teams
- • Reactive door-maintenance firms needing fast like-for-like replacements
What a complete kit includes
- • Fabricated frames and leaves to your signed CAD
- • Beads, gaskets and fixings — in the box, not billed separately
- • The specified hardware schedule fitted or supplied to fit
- • Glass supplied or coordinated to the build-up you quoted
- • Every item labelled by opening reference, palletised in fit order
The product range spans commercial entrance doors, shopfront doors, thermally broken entrance doors, windows, curtain walling and louvre panel doors — all supplied the same supply-only way.
Straight answers to the questions we get
Do you supply the automatic operator?
No. We supply the frame only, prepared to the operator's specification. Our automatic sliding door frames are built bi-parting or single-slide for integration with a third-party operator that you or your automation specialist source and commission. Tell us the operator make and model at quote stage and we will fabricate the frame to suit it. The drive gear, sensors and controls are not ours to supply.
Can you match an existing system?
Often, yes — especially on reactive replacement work where the existing frame stays and only a leaf or section is failing. We fabricate on Jack Aluminium and compatible system platforms, so where the existing profile is one we can match or interface with, we will. Send photos, sightline measurements and any system markings with the survey. If a true like-for-like is not possible, we will tell you that on the quote rather than after manufacture. Our primer on Jack Aluminium systems compatibility covers what to capture.
What's the lead time?
Quotes come back within 24 hours. Standard fabrication lead time is 21 days as an aim from confirmed order and signed CAD. Reactive and rush work can move faster — if you are working a breakdown or a tight programme, flag it on the enquiry and we will tell you honestly what is achievable.

Do you deliver?
Yes — palletised, from Warrington to anywhere in mainland Britain, labelled by opening reference. Trade customers near our Warrington workshop can also collect. What we do not do is turn up to fit it: delivery is to your address or site, and the install is yours.
Will you ever quote my end client directly?
No. We are trade-only by design. We do not sell to homeowners or building owners, and we do not approach the end clients behind your jobs. If a member of the public contacts us, we point them to a trade installer. Your customer relationships are not something we touch.
