Perforated sheets and perforated sheet products from 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... 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

Delivery of a 400 tonne press in 1979

In 1979, a 400 tonne press was delivered to Dillinger Lochbleche. Today it continues to do its work in our subsidiary DF-Bulgaria. The former managing director Dr. Walter Koch and Hans Ulrich Koch are pictured on the left setting up the press.

Delivery of a 600 tonne press in 2021

In June 2021, a new 600-tonne Soehnen wide press was delivered to Dillinger Lochbleche. Again, 42 years later, the current Managing Director Hans Ulrich Koch and the former Managing Director Dr Walter Koch accept the press at the same location. 

With the delivery and installation of the new Soenen wide press, we are now able to offer you a broader portfolio. New hole patterns are possible as well as larger widths. We would be happy to inform you about all the new possibilities in a short conversation. The use of the most modern tools and the resulting more effective, more versatile production will have a positive effect on the tasks to be realised. We look forward to offering you this additional service in the future.

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 )
