Steffen Fils

Steffen Fils: your expert in metal constructions for almost 60 years in Thônex-Genève

The Steffen Fils company was founded in 1960 by Walter Steffen, an electrician by training. He was joined by his son Thierry Steffen in 1986, a metal builder and locksmith by trade.

For the first 45 years of its existence, the company focused on the construction of electrical switchboards. And since 2005-2006, it has opened up and broadened its activity to other fields such as general ironwork and metal construction (grinding parts, drilling holes, cutting, bending, repairs, etc.

.

With their workshop equipped with all the necessary tools and machinery, Walter and Thierry Steffen work alongside 3 workers and provide their services to both companies and individuals.

In fact, they often collaborate with architects, landscape designers or other trades to realize metal furniture pieces such as Corten steel planters, deckchairs to precise designs, replicas of existing models in series, bookcases, store displays, tables and bases for garden statues, etc.

Steffen Fils carries out all industrial sheet metal work and metal constructions

Steffen Fils offers its services for standard metal construction work such as:

• electrical switchboard fabrication (metal enclosure)
• fittings for boats (fittings, pulley returns, rope fittings, etc.)
• barriers
• doors
• slopes

We are able to create all kinds of bespoke constructions or carry out isolated work, thanks to a range of services listed below.

Welding

We weld all types of components made of aluminum, stainless steel and steel.

Turning, punching and milling

With all the equipment required for complete machining of parts, we carry out turning, punching and milling operations to make precise cuts in sheet metal.

These processes make it possible to add components to an element, such as special hinges to a door.

Plasma cutting

Thanks to plasma technology, we can cut sheet metal according to precise drawings (whether yours or drawings we also design on request).

Plasma can thus be used to cut shapes, logos and all kinds of elements from sheet metal (steel or stainless steel) to a dimension of between 3 and 50 mm.

We draw up plans on the computer, from which we create a computer file in DXF format, which we insert into the plasma machine, which then takes charge of making the cut according to this precise plan.

If you'd like to draw the plan yourself, simply send us the file and we'll take care of the rest.

Folding and shearing

These techniques, which produce a straight cut in the sheet metal, prove essential for the creation of standard metal constructions such as:

• stainless steel kitchen fittings
• water returns
• window sills
• door panels
• retention tanks for cisterns, vats or tanks

Sheet metal shaping is a breeze thanks to folding and shearing.

Spray painting

Before handing over a finished product, rather than powder coating, we prefer the spray-painting technique, as this provides a finer, more precise result.

Industrial metalwork:

• Cutting,
• Bending,
• Turning,
• Welding (aluminum, stainless steel),
• Furnace painting,
• Electrical enclosure manufacturing.
