Extension unit S19 suitable for models Siegen S16, S17, S18 - 430cm x 233cm

Siegen S19 measures 4,300 mm in width, 2,330 mm in depth and 2,250 mm in height. The roofed footprint is 9.90 m², the weight around 188 kg.

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

In centimeters this comes to 430 cm × 233 cm × 225 cm (W × D × H) – this is the dimension you should allow for the foundation area.

Siegen S19 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 S19. 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.

Get in touch with us if you need further documents for a construction project.

Siegen S19 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; 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 S19 is an add-on unit and 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 188 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 188 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 S19 hot-dip galvanized (item no. 102001558). 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 S19 is delivered without walls. A rear wall of trapezoidal sheet can be added, and side walls in either trapezoidal sheet or opal-transparent polyester. You decide whether the canopy is built open, half-open or closed.

The mono-pitch roof drains freely to the rear, dripping off over the roof fascia that is bolted on three sides. A gutter and downpipe are available as options and can also be fitted later.

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.

No. Siegen S19 is an extension module and requires an existing base unit. It fits the Siegen S16, S17 and S18 models.

The add-on unit contains fewer components than a base unit of the same size – 188 kg compared with 250 kg – because it also uses the row of posts of the base unit on the connecting side. That is exactly what makes the extension economical: you do not pay twice for the same row of posts.

Several add-on units can be lined up one behind the other, so installations of any length can be created. Extension is still possible years later because the system is standardized and all connections are bolted.

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 S19 this is 22.5 m³ gross volume (external dimensions 430 cm × 233 cm × 225 cm), with a roofed area of 9.90 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 S19 roofs 9.90 m². Depending on the use, this results in:

• 9 to 19 people as a smoking shelter or weather shelter (calculated at 0.5 to 1 m² per person)
• 8 bins of 120 l side by side along the rear wall or 3 waste containers of 1,100 l
• 6 euro pallets

The number of people is a guide value derived from the area and the clear dimensions; the figures for bins, containers and pallets come from the manufacturer.
