Köln K4 b/c measures 4,195 mm in width, 2,165 mm in depth and 2,510 mm in height. The covered floor area is 8.50 m².

Clear width 4,075 mm, clear depth 2,105 mm, clear height 2,360 mm – the clear height is the usable passage height under the roof structure.

For foundation planning, allow for 420 cm × 217 cm (W × D). The EAN of this model is 4250366528434, the item number 102001721.

Köln K4 b/c is designed for wind load zones 1 to 3. With the snow load there is a difference you should be aware of before ordering:

• welded and assembled at the factory: Sk = 1.90 kN/m²
• as a kit for self-assembly: Sk = 1.45 kN/m²

1.90 kN/m² is a high value for a shelter – around two and a half times what simple kit canopies carry. This means Köln also covers snow load zones 2 and 3 at medium altitudes. The kit version is lower at 1.45 kN/m²; in that case check the snow load zone of your municipality in accordance with DIN EN 1991-1-3.

The load-bearing structure consists of round tube with a diameter of 60 mm, factory-welded and hot-dip galvanized.

Yes. A verified type-tested structural calculation is available for Köln K4 b/c. That is the key difference from simple kit canopies and the reason why the Köln series is used in tenders and by public-sector clients.

In practical terms this means: the structural stability certificate has already been provided and does not have to be drawn up project-specifically by a structural engineer. That saves time and costs in the approval procedure.

The type-tested structural calculation does not replace a building permit – whether your project requires a permit is governed by the state building code. It does, however, replace the structural certificate within the procedure. The data sheet, the tender text as a bill-of-quantities item and the GAEB file (DA XML 3.1, X81) are available for download on this page.

Köln K4 b/c is dowelled to a foundation provided on site. The drilling depth is at least 100 mm and must be free of reinforcement. The design is based on normal soil conditions with a permissible ground pressure of 2 kg/cm².

Three points determine whether installation runs smoothly:

• The foundation must be level; a maximum height difference of ± 5 mm is permitted.
• Dowels must not be set in paved or asphalt surfaces.
• No utility lines may run in the area of the ground anchoring.

If the top edge of the finished floor is 20 cm lower because the substrate is paved, the posts are available extended by 20 cm. Alternatively, we supply a ready-made concrete foundation slab: it is laid at ground level on a sand or gravel bed prepared on site, has a textured surface of slip resistance class R13, a stone joint grid of 300 × 300 mm and already includes the structurally required reinforcement of up to 15 kg/m². This eliminates the foundation work completely.

You receive the foundation plan with the order confirmation. A longitudinal or transverse slope is not taken into account in the standard offer; an adjustment for slope is possible at extra cost.

Both – you decide. Both versions are the same item; you make the selection in the configurator.

• Fully assembled: completely built at the manufacturer's plant, delivered and positioned by crane truck directly at the installation site.
• Kit: a sensible choice where site access is restricted or if you carry out the assembly yourself. Assembly instructions are included.

Four options are available for delivery: collection from the factory, delivery with self-unloading by forklift or crane provided on site, delivery and unloading by crane truck without assembly, or delivery and unloading by crane truck including on-site assembly and ground anchoring.

Note the difference in snow load: 1.90 kN/m² when assembled at the factory, 1.45 kN/m² as a kit. Before production starts you receive a CAD plan for fine-tuning – manufacturing only begins after your approval.

The delivery time is 3 to 5 weeks from approval of the CAD plan. Köln is manufactured and welded to order, which is why it is longer than that of kit series such as Leipzig or Jena.

Shipping is free – within Germany as well as to Austria, Belgium, France, Italy, Luxembourg, the Netherlands and the Czech Republic. Even at this size, no bulky goods or freight forwarding surcharge applies.

Clarify site access before ordering: with the fully assembled version, a crane truck must be able to reach the installation site and set up its outriggers there. If that is not possible, delivery as a kit is the right way to go.

“b/c” is the manufacturer's code for the wall configuration – it describes how far the unit is enclosed. The first letter refers to one side, the second to the other; versions such as a/b and b/a are therefore mirror images of each other. How many wall panels this actually means is set out in the next paragraph.

Köln K4 b/c has a 4-panel rear wall and side walls on the left and right, all made of toughened safety glass with aluminum glass holders. In total there are 9 wall elements.

You can see how the panels are arranged in detail in the product photos on this page – one access opening remains open in every version. If you need a different layout, for example a protected interior or an access door, that can be done; just ask us.

Four materials are available to choose from, all in the same frame system with aluminum glass holders:

• Toughened safety glass (ESG), clear and transparent – the standard version
• ESG with ceramic screen printing, motif of your choice – more opaque, plus a visual screen against bird strikes
• Perforated aluminum sheet in the frame color – robust, well ventilated at the rear, resistant to vandalism
• Douglas fir timber cladding – a warmer look, suitable for parks, schools and residential settings

ESG is the most common choice because it keeps the unit transparent and the location visible – a safety argument at stops, schools and on company premises. In the event of deliberate damage, ESG breaks into blunt granules instead of sharp shards.

The standard color is RAL 7016 Anthracite grey. Beyond that, the frame is available in any RAL or DB color; the roof soffit is finished as standard in RAL 9002 Grey white so that it stays bright under the roof.

The corrosion protection is built up in three stages: hot-dip galvanized, primed and color-coated, or painted with an environmentally friendly two-component paint.

This corresponds to corrosivity category C4 medium based on DIN EN ISO 12944-2 – designed for industrial atmospheres and coastal areas with moderate salt exposure. For an outdoor canopy this is considerably more than the usual standard and the reason why the manufacturer gives a 5-year warranty on the structure.

Four options can be integrated directly into the structure:

• Green roof: modular sedum elements that can be fitted into the trapezoidal profile of the roof – often a plus for municipal projects and compensation areas
• InLight lighting with presence detector, vandal-resistant and integrated into the roof structure
• VersoVolt photovoltaic system for self-sufficient power supply to the lighting – with no excavation work and no power connection
• Ready-made concrete foundation slab, which eliminates the foundation work

On top of that comes the cladding of your choice and, with ESG featuring ceramic screen printing, a motif of your choice. You can put together what you need in the configurator on this page.

That depends on the federal state and cannot be answered across the board – the state building code governs this, not the manufacturer.

The figure your building authority asks for first is the enclosed volume. For Köln K4 b/c this is 22.8 m³ gross volume (external dimensions 420 cm × 217 cm × 251 cm), and the covered area is 8.50 m². Depending on the federal state, the state building codes tie the exemption from permit procedures for roofed structures without habitable rooms either to the volume (often between 20 and 75 m³) or to the floor area. In undeveloped outlying areas the exemption usually does not apply.

A verified type-tested structural calculation is available for Köln K4 b/c. In the procedure it replaces the project-specific structural stability certificate, but not the permit itself.

Regardless of this, setback distances to the property line, the local development plan and the local design statute must be complied with. Check with your municipality before ordering – we are not building consultants and cannot replace the information provided by the authority. You can get the documents for the inquiry from us as a PDF.

Köln K4 b/c covers 8.50 m². Depending on the use, this results in:

• 5 people at 1.8 m distance – 8 to 17 people in normal operation (calculated at 0.5 to 1 m² per person)
• 5 bicycles by calculation at 70 cm wheel spacing
• 8 bins of 120 l side by side
• 2 waste containers of 1,100 l
• 6 Euro pallets

The figures for people, bins, containers and pallets come from the manufacturer; the bicycle figure is calculated from the clear width. Because the access stays open and the clear height is 2,360 mm, cargo bikes and equipment with excess height are no problem either.

Ja. Jedes der 9 Wandfelder von Köln K4 b/c lässt sich statt mit einer Glasscheibe mit einem Holzelement aus Douglasie ausführen. Der Aufpreis beträgt 190 € je Feld, bei 9 Feldern also 1.710 € inkl. MwSt.

Zum Vergleich: ESG mit keramischem Siebdruck kostet 60 € je Feld (540 €), Lochblech aus Aluminium in Rahmenfarbe 140 € je Feld (1.260 €). Klares ESG ist im Grundpreis enthalten.

Die Holzelemente sitzen im selben Rahmen wie die Glasscheiben und werden oben und unten mit Aluminium-Haltern am Rahmenriegel gehalten. In der Bildergalerie dieser Seite sehen Sie Köln K4 b/c als Visualisierung mit Holzverkleidung. Die Verkleidung wählen Sie im Konfigurator auf dieser Seite.
