For businesses

Cooperation

We work with installation companies, contractors and developers. The scope varies - from single subcontracted jobs to whole developments with a repeated size.

Doors are sold differently from most building materials - you cannot order them from stock and swap them when the size turns out wrong.

Every construction is built for one specific opening, so a mistake in the order does not end with a return but with production from scratch. For an installation company that means the supplier is only as good as their accuracy and whether someone picks up the phone when something on site does not add up.

We work with installation companies, contractors and developers in the region. The scope varies: from single subcontracted jobs to whole developments with a repeated size. We agree terms individually, because working on a few doors a year looks different from working on several dozen.

We do not publish a price list or a discount table - with a made-to-measure product such a table would not answer the question of what a specific job costs anyway. Instead we suggest a conversation about what you will actually be ordering.

The three kinds of cooperation we run most often

  • Installation companies

    A steady supplier instead of a search on every job

    If you install garage doors, the time goes not into the installation itself but into putting the order together and clearing up discrepancies. With a steady arrangement we know how you work, and you do not have to explain what you need from scratch on every job.

    What happens after installation matters just as much. A door runs for fifteen years and sooner or later a spring needs replacing or a remote reprogramming. With a steady supplier you do not start by working out who sold it and which model is actually hanging in the opening.

    • Doors, automation and accessories from one range
    • Support in matching the drive to leaf weight and duty cycle
    • Documentation and warranty terms to pass on to your customer
    • Help with an unusual opening before the order goes into production
    • The same contact person on every job
  • Developers and contractors

    One repeated size across the whole development

    On terraced housing or an estate the problem is not a single door but making them all look the same and arrive on site when they are needed. Panels painted in distant batches can drift slightly in shade - with doors standing side by side you notice immediately.

    The second issue is when the survey happens. An opening measured before plastering almost never matches what is left afterwards, and with a dozen doors at once a mistake affects the whole series, not one unit. So on developments we agree explicitly at what stage the measuring is done.

    • One embossing, colour and texture across the development
    • The full set ordered as one job, not in batches
    • Certificates and documentation needed at handover
    • Survey at the stage where the opening has its final size
    • Delivery schedule agreed in advance
  • Architects and designers

    Technical data before the drawing reaches site

    A door specified without checking the lintel and the room under the ceiling can force alterations at the stage where they cost the most. We are happy to check the assumptions earlier - especially with unusual openings and existing buildings.

    It also matters for the massing. The type of construction determines how much room the door takes under the ceiling and whether the intended opening height can be kept. If the drawing shows a roller or side-hinged door, it is worth checking that against the conditions before the lintel is built.

    • Consultation on the solution at the design stage
    • The full palette of finishes, embossings and textures
    • Construction matched to the conditions in the building
    • A check on the lintel and the room under the ceiling
    • Door finishes matched to the façade

What you get besides the door itself

Working with a door supplier comes down in practice to a few things: whether the order is prepared properly, whether someone helps with an unusual case, and whether there is anyone to come back to after installation. We try not to fail on those three.

Technical selection
A drive is matched to the weight of the leaf and the number of daily openings, not to a catalogue average. With an unusual building we check it together before the order goes into production.
One supplier for the whole range
Garage and industrial doors, automation and accessories. Finishes can be matched, because they come from the same palette.
Documentation and certificates
CE certification carried out by TÜV, compliance with national and European standards, tested construction and thermal parameters. The full set is sometimes needed at building handover.
Made to measure
An opening after plastering rarely matches the drawings. The construction is built to the size taken on site, including in existing buildings.
Service after installation
We stay with the building for as long as it runs. Under continuous duty what counts is parts availability and response time, not just the price of the drive.
One person to talk to
The same person handles the job from quote to handover, so you do not have to explain the case again on every call.

How we start

No registration forms and no declarations signed blind. First a conversation about what you will actually be ordering, then terms in writing.

+48 530 523 233

  1. Get in touch

    Call or write. To start with it is enough to tell us what you do and the scale of orders you expect - we need no documents at this stage.

  2. A talk about scope

    We work out what you will actually be ordering: doors alone or complete with automation, one-off or ongoing. The terms we can offer follow from that.

  3. Terms of cooperation

    We set out terms matched to that scope. Everything goes in writing, so that on the third job nobody has to recall how it was agreed.

  4. The first job

    We usually start with a single order, on which both sides see how it works in practice. That is fairer than signing a large contract blind.

The questions we hear most often

Some answers come down to “we agree it individually”, and that is genuinely the case - with a made-to-measure product a fixed table would not answer your question anyway.

  • What are the commercial terms and discounts?

    We agree them individually, after a conversation about the scope of cooperation. We do not publish a discount table, because with a made-to-measure product it would not answer the question of what a specific job costs - and that is the only question that matters.

  • Is there a minimum turnover commitment?

    Let us discuss that when we agree terms. Working on a few doors a year looks different from working on several dozen, and there is no sense in forcing one rule on both.

  • Do you install yourselves, or only supply?

    We do not install ourselves. Measuring and installation for customers are done by our authorised partners, and we supply doors and automation to installation companies. If you install doors, get in touch - we will tell you how to become a partner.

  • Who takes the measurements on subcontracted jobs?

    It depends on what we agree. The survey decides whether the door fits the opening at all, so we always state plainly who is responsible for the dimensions - before anything goes into production.

  • Will I get material to show my customer?

    We show the colour and texture sample book at the quoting stage - samples on screen can differ from the real shade. The full range with model parameters is available on this site.

  • What area do you cover?

    We work with companies in the region, and for larger developments we agree the reach individually. The simplest thing is to ask - we will say plainly whether we can handle the job.

Tell us what you do

You need no documents for the first conversation. Just tell us what kind of jobs you run and what you are looking for in a supplier.
