Köln K4 f/a 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 4250366533193, the article number 102001390.

Köln K4 f/a is designed for wind load zones 1 to 3. For the snow load there is a difference you should know before ordering:

• factory-welded and assembled: 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 canopy – roughly two and a half times what simple kit canopies support. 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 according to DIN EN 1991-1-3.

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

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

In practice this means: the stability verification has already been provided and does not have to be prepared for the specific project by a structural engineer. This saves time and costs in the approval procedure.

The type-tested structural calculation does not replace a building permit – whether your project requires approval is governed by the state building code. However, it does replace the structural verification 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 f/a 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 2 kg/cm² permissible ground pressure.

Three points determine a smooth installation:

• The foundation must be level; a maximum height difference of ± 5 mm is permissible.
• Dowelling must not be done on paved or asphalt surfaces.
• No utility lines may run in the area of the ground dowelling.

If the top edge of the finished floor is 20 cm lower because the surface is paved, the posts are available extended by 20 cm. Alternatively, we supply a precast 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 will receive the foundation plan with the order confirmation. A longitudinal or transverse slope is not included in the standard offer; a slope adjustment is possible for an additional charge.

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, delivery and positioning by crane truck directly at the installation site.
• Kit: useful when access is restricted or if you assemble it yourself. Assembly instructions are included.

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

Note the difference in snow load: factory-assembled 1.90 kN/m², as a kit 1.45 kN/m². Before production begins, you will receive a CAD plan for fine-tuning – production only starts 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, there is no bulky-goods or freight-forwarding surcharge.

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

"f/a" is the manufacturer's code for the wall configuration — it describes how far the structure 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 involves is stated in the next paragraph.

Köln K4 f/a has a 4-panel rear wall and side walls on the left and right, all made of tempered safety glass with aluminum glass holders. There are 11 wall elements in total.

You can see how the panels are arranged in detail in the product photos on this page — one access point stays open in every version. If you need a different layout, such as a protected interior or an access door, that can be done; ask us.

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

• Tempered safety glass (ESG), clear and transparent — the standard version
• ESG with ceramic screen printing, motif of your choice — more opaque, plus visual protection against bird strikes
• Aluminum perforated sheet in the frame color — robust, well ventilated, resistant to vandalism
• Timber cladding in Douglas fir — a warmer look, suited to parks, schools and residential settings

ESG is the most common choice because it keeps the structure 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 rather than shards.

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

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, that is considerably more than the usual standard and the reason 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 fit into the trapezoidal profile of the roof — often a plus point for municipal projects and compensation areas
• InLight lighting with a presence detector, vandal-proof and integrated into the roof structure
• VersoVolt photovoltaic system for self-sufficient power supply to the lighting — without excavation work and without a power connection
• Ready-made concrete foundation slab, which eliminates the foundation work

Added to this is the cladding of your choice and, for ESG with ceramic screen printing, a motif of your choice. You put together what you need in the configurator on this page.

This depends on the state and cannot be answered across the board — the state building code is responsible, not the manufacturer.

The figure your building authority asks for first is the enclosed space. For Köln K4 f/a, that is 22.8 m³ gross volume (external dimensions 420 cm × 217 cm × 251 cm), and the covered area is 8.50 m². The state building codes tie the exemption from approval of roofed structures without occupied rooms to the volume (often between 20 and 75 m³) or to the floor area, depending on the state. In the outlying area, the exemption usually does not apply.

A type-tested structural calculation is available for Köln K4 f/a. Within the process, it replaces the project-specific structural stability verification, but not the permit itself.

Regardless of this, setback areas to the property boundary, the development plan and the local design statute must be observed. Ask your municipality before ordering — we are not building consultants and cannot replace the information provided by the authority. You receive the documents for the enquiry from us as a PDF.

Köln K4 f/a covers 8.50 m². Depending on use, this results in:

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

The figures for people, waste bins, containers and pallets come from the manufacturer; the number of bikes is a calculation based on the clear width. Because the access stays open and the clear height is 2,360 mm, cargo bikes and equipment with excess height are also no problem.

Ja. Jedes der 11 Wandfelder von Köln K4 f/a lässt sich statt mit einer Glasscheibe mit einem Holzelement aus Douglasie ausführen. Der Aufpreis beträgt 190 € je Feld, bei 11 Feldern also 2.090 € inkl. MwSt.

Zum Vergleich: ESG mit keramischem Siebdruck kostet 60 € je Feld (660 €), Lochblech aus Aluminium in Rahmenfarbe 140 € je Feld (1.540 €). 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 f/a als Visualisierung mit Holzverkleidung. Die Verkleidung wählen Sie im Konfigurator auf dieser Seite.
