Industrial doors

Matched to the duty cycle, not to an average

Sectional, glazed aluminium and side-hinged. We match the drive to the weight of the leaf and to how often the door actually runs - because that decides when you will be calling out a service engineer.

Models

Four constructions, different building conditions

The choice starts with how much room you have above the opening and whether the space needs daylight.

Questions

Before you ask for a quote

The questions we hear most often about this category. If yours is not here, call us - we usually reply the same working day.

  • How large an opening can you close?

    Industrial constructions cover openings clearly larger than garage ones. The exact range depends on the model and the tracking, so we confirm it when quoting, once we know the size of the opening.

  • What power supply is needed?

    That is the first question with a door in a commercial building. Large leaves and continuous duty often need a three-phase supply, which has to be brought in before installation. We settle it before quoting, so it does not come as a surprise on site.

  • What decides the choice under continuous duty?

    The real number of cycles, not a catalogue average. Under heavy use, parts availability and service response time matter just as much - they decide how long the door actually stands idle when something fails.

  • Why are there no prices on the site?

    Every order is made in a specific size and finish, and on top of that come site conditions that differ with every opening. A price list for a product like this would be fiction, so an advisor prepares the quote once the details are settled.

  • Who takes the measurements?

    An authorised partner near you - they come to the site before production starts. That stage decides whether the installation goes without alterations, so we do not rely on dimensions given over the phone.

  • Who installs the door?

    Installation is done by our authorised partners. We will gladly refer you to a partner near you, who will come to the site, take the measurements and then install the door. You will find the nearest points on the “Where to buy” page.

  • How long does it take?

    We confirm the date when quoting, because it depends on the model, the finish and how full the production schedule is. For unusual sizes we agree it individually - we would rather give a realistic date than a prettier one.

  • Will I see the colours before ordering?

    Yes. The samples on the site are indicative, and a shade on screen can differ from the real one. We show the sample book before you order.

How it looks in a building

  • Bramy przemysłowe w ceglanym budynku poprzemysłowym

In a commercial building the door is chosen by the number of openings, not by the width of the hole - and by what power you have on site.

A door in a hall works in a completely different regime than a domestic one. Dozens of cycles a day put a load on it that a household construction will not take, and downtime after a failure costs more than the door itself. So with commercial buildings we start from the real number of openings and the way the door is used, and only then talk about size and finish.

The second question is the power supply. Large leaves and continuous operation often need a three-phase feed, which has to reach the installation point before the door goes in. This is one of the most common causes of delay: the door is ready and there is nothing in the hall to power it. We settle this at the quoting stage, not on site.

Sectional constructions cover most uses in halls, warehouses and at loading bays. An aluminium version with glazing makes sense where daylight matters - a row of windows in the door can cost less than lighting the hall artificially through the whole working day. Side-hinged doors are used in buildings where there is no room for tracks above the opening.

What to consider when choosing

Cycles per day
The basis for choosing the construction and the drive. A catalogue average reflects neither shift work nor seasonal peaks.
Available power supply
230 V is enough for smaller doors. Large leaves and continuous duty need 400 V brought in before installation.
Need for daylight
A row of glazing or an aluminium frame instead of a solid panel. That decision belongs to the model stage, not after installation.
Service and parts
Under continuous duty what counts is response time and parts availability, not just the price of the door.

Describe the building and we will pick the construction

The size of the opening, how it will be used and the number of cycles a day - that is enough to start a conversation about a quote.
