Welcome to Dillinger Fabrik gelochter Bleche GmbH

As one of the leading manufacturers of perforated metal in Europe, our large production depth allows us to offer you a wide and unique range of products.

With our modern machinery we are able to fulfil almost every customer-specific task.
The complete production of perforated plates from a single source gives our customers the advantage of making the best possible use of existing synergy potentials.

A short film will give you an insight into our world of perforated plates.

Innovation begins with an idea.
The idea of combining functionality with unlimited possibilities.

State-of-the-art production facilities and optimised internal and external logistics guarantee a fast and careful implementation of your ideas.

On request, we are happy to advise our customers, with our experienced, multilingual team of engineers, right from the planning phase.


In addition to the production of flat perforated plates, the further processing of perforated plates into more complex, ready-to-install assemblies and vendor parts has become a focal point of activity in our company in recent years.

Our possibilities in the area of further processing include:

- Straightening, drawing
- Cutting, Edging, Laser
- Bending, rounding, joining, welding, clinching, etc.

Price and delivery time play a decisive role alongside quality. DF meets these requirements by offering the possibility to keep custom-made products in our warehouse and to deliver on time on call.

In this way, DF customers benefit at the same time from the cost advantages of higher production lot sizes as well as the delivery time advantages of parts held in stock - quality just in time.

In addition to this comprehensive range of services, we also have an extensive stock range with over 300 items of perforated plates...

 ...in the material types:

- Steel
- Galvanized steel
- Stainless steel
- Aluminium

 ...and with the perforations:

- Round holes offset
- Round perforation straight standing
- Square perforation straight
- Hexagonal perforatio

Two years of planning, one year of construction, total investment 3.1 million euros: Dillinger Fabrik gelochter Bleche GmbH is investing heavily in its future by building a new 3200 sqm hall. "In Corona times, this is good news after all", explained Mayor Franz-Josef Berg. He accepted the invitation of the managing partner, Hans-Ulrich Koch, to visit the company to find out about the further development of the traditional company and was impressed after a tour of the factory. This year, the company is looking back on its 125th anniversary. Due to the Corona pandemic, the anniversary celebration and an official inauguration of the new hall were cancelled.

Founded in 1895, Dillinger Fabrik gelochter Bleche GmbH has specialised in the manufacture of perforated sheets and is today one of the leading perforated sheet manufacturers in Europe. As Hans Ulrich Koch said: "one is always looking for niches", and obviously very successfully so. The perforated sheeting products are supplied to more than 20 countries via foreign partners. Together with its subsidiaries and sister companies, the DF Group employs around 400 people, 250 of whom work in Dillingen. The new production facility and the expansion of the product range could create up to 25 new jobs. This depends not least on further developments.

Although the Corona crisis has also forced the DF group of companies to introduce short-time working, the company is looking to the future with confidence as it has established a broad-based production base. "Of course, this year has hit us hard, but if the measures taken by politicians in the economy take effect, we hope for a good year 2021", Mr Koch explained. In addition to the new hall, the company has invested around 7 million euros in state-of-the-art technology at all its sites in recent years.

Together with Managing Director T. Kraus and A. Rospert (Preziehs GmbH & Co KG), a sister company of the DF Group, Mr Koch guided the mayor through the production halls. There, Mr. Berg was shown a small impression of the range of the specialist for perforated sheets. "I am glad that we have such a large company in Dillingen, which makes an important contribution as an employer through investments and innovations. I wish the group of companies continued success for the future," said the mayor. ( Source: City of Dillingen / Theobald )

At the moment, the Dillinger Fabrik gelochter Bleche is working on the realisation of an exterior façade for the new multi-storey car park at the Bethel Clinic in Bielefeld. The existing capacities can thereby be increased by far and the existing parking situation will be relieved. With our patented Perfo©Art process, we will design the exterior walls with a realistic forest motif. Since the motifs are vectorised and applied to the individual façade panels, almost any conceivable enlargement of the motif is possible. Each panel gets a number and is mounted according to a precise construction plan. We have already worked in a similar way on the design of an Aldi car park.
