Siegen S27 measures 2,975 mm in width, 4,660 mm in depth and 2,250 mm in height. The roofed footprint is 12.80 m², the weight around 370 kg.

The clear width is 2,925 mm and the clear height – that is, the usable headroom under the structure – is 2,000 mm.

In centimeters this comes to 298 cm × 466 cm × 225 cm (W × D × H) – this is the dimension you should allow for the foundation area.

Siegen S27 is designed for a snow load of 0.75 kN/m² and wind load zones 1 to 2. The structure is made of hot-dip galvanized steel tube with a diameter of 50 mm.

0.75 kN/m² corresponds to around 30 cm of powder snow or about 10 cm of wet old snow. For sites in snow load zones 2a, 2 and 3 – that is, large parts of the low mountain ranges, the Alpine foothills and north-eastern Germany – or at altitudes above about 300 m, you should check the snow load for your municipality before ordering. The governing value is given in the snow load zone map according to DIN EN 1991-1-3 and is available from your building supervisory authority.

Regardless of this: in the event of exceptional snowfall, the roof must be cleared.

There is no type-tested structural calculation for Siegen S27. That is the normal case for canopies of this size – the range is placed on the market as a standard kit and not as a type-tested construction product.

If your building supervisory authority requires a structural stability certificate, it is drawn up for the specific project by a structural engineer. We supply the basis for this: foundation plan, assembly plan, dimensioned drawing and the manufacturer's load assumptions. In addition, we provide a data sheet, a tender text as a bill-of-quantities item and a GAEB file (DA XML 3.1, X81) for download with every model.

Siegen S27 is dowelled to the ground. A level, load-bearing subsurface founded below the frost line is required – a continuous concrete foundation or point foundations under the posts. Asphalt, interlocking pavers without a bound base course or undisturbed soil are not sufficient.

The stainless steel ground mounting material is included with the kit, as is a foundation plan with the exact anchor points. The plan specifies the drilling patterns for each post of both rows of posts; the foundations should be cured before delivery.

Installation over paving – that is, setting the unit up on an existing paved surface without its own foundation – is not intended for this model.

Siegen S27 is supplied as a kit for self-assembly. The structure is fully bolted together, there is no welding.

The scope of delivery includes the complete kit, foundation and assembly plan, illustrated assembly instructions and the stainless steel ground mounting material. The concrete foundation, tools and lifting aid are provided by you.

You should plan on two to three people for assembly – the roof elements are bulky and the total weight is around 370 kg. The manufacturer provides a 5-year warranty on the structure.

The delivery time is 1 to 3 weeks from receipt of order.

Shipping is free – within Germany as well as to Austria, Belgium, France, Italy, Luxembourg, the Netherlands and the Czech Republic. Although this is a freight forwarding item, no bulky goods or freight surcharge applies. That is the exception in this market: several competitors add 220 to 290 euros of freight per unit for this range.

Delivery is by freight forwarder, and the delivery date is announced in advance. With around 370 kg spread over several packages and bulky long parts, you need an unloading point that can be reached by truck and helpers for unloading.

We supply Siegen S27 hot-dip galvanized (item no. 102001586). Hot-dip galvanizing to DIN EN ISO 1461 is the most durable corrosion protection for steel outdoors and is maintenance-free.

An additional color coating can be produced at the factory, but it is not part of our standard range. If you need the Siegen range in a RAL color, send us an enquiry – we will obtain a quote for you.

Siegen S27 is delivered without walls. A rear wall of trapezoidal sheet can be added, and side walls in either trapezoidal sheet or opal-transparent polyester. With the double-sided units, both long sides can be closed independently of each other.

A gutter and downpipe are included as standard with the double-sided units – the roof drains in the middle between the two bays and therefore needs a gutter.

You select the wall elements directly on the product page and the price updates immediately. Retrofitting is possible at any time because all elements are bolted together.

Yes. For Siegen S27 there is the Siegen S29 add-on unit (item no. 102001560, galvanized). It is attached at the side and increases the roofed area by 19.80 m² at the same structural depth.

The add-on unit also uses the row of posts of the base unit and is therefore less expensive than a second base unit. Several add-on units can be lined up one behind the other.

Because the system is standardized and bolted together throughout, the extension also works years after the initial assembly. It is best to plan the foundations for the later expansion stage right away.

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

The figure your building authority asks for first is the enclosed volume. For Siegen S27 this is 31.2 m³ gross volume (external dimensions 298 cm × 466 cm × 225 cm), with a roofed area of 12.80 m². Depending on the federal state, the state building codes link the exemption from approval procedures for roofed structures without habitable rooms either to the volume (frequently between 20 and 75 m³) or to the footprint. In outlying areas the exemption usually does not apply.

Regardless of the permit question, the setback distances to the property line, the development plan and the local design statutes must be observed. For commercial sites, fire protection and workplace requirements may apply as well, depending on the use.

Check briefly with your local municipality before ordering. We are not building consultants and cannot replace the information provided by the authority – you can get the documents for the enquiry (dimensioned drawing, data sheet, foundation plan) from us as a PDF.

Siegen S27 roofs 12.80 m². Depending on the use, this results in:

• 12 to 25 people as a smoking shelter or weather shelter (calculated at 0.5 to 1 m² per person)
• 8 bikes on paper at a wheel spacing of 70 cm – parked on both sides
• 5 bins of 120 l side by side along the rear wall or 2 waste containers of 1,100 l

The figures for people and bikes are guide values derived from the area and the clear dimensions; the figures for bins and containers come from the manufacturer. For bikes the following applies: with leaning bars or row parkers the number can be increased, with cargo bikes or pedelecs with wide handlebars it decreases.
