Our small family-run company has been active in the field of metalworking, with a focus on sheet metal and structural steel, welded parts since 2001. In addition to deliveries to customers in Turkey, we also export to Germany in the automotive and construction sectors. Our strength is the flexible production of high quality at low prices, even for smaller ones going on sizes.
We can offer laser and folding sheet metal parts up to 10 mm thick and 2000 mm long. We have been working successfully for many years with neighboring companies in the Nilüfer industrial area in Bursa for turning and milling parts.
We have coatings carried out by an experienced specialist company in the nearby industrial area in Bursa.
This certified company supplies galvanic coatings, Geomet, KTL and powder coating according to OEM standards for the automotive industry.

For all your spare parts and high performance valves

The AZ Factory is your source for waterjet cutting, CNC turning, CNC milling, manufacturing of welded assemblies and assembly.

We supply from prototypes to series from a single source and provide maximum availability and flexibility with high precision and punctuality!

We are specialists for the "non-specialized"

Steel construction and mechanical engineering, which is not in the question. Everything is made of the material steel feasible and our resources equivalent (tools, lifting equipment and hall size) is in safe hands. This web site aims to show the diversity of our work and its applications.

Our Viernheimer family business has evolved from humble beginnings to become the partner of big industry. We manufacture individual steel construction such as operating platforms, steel parts for turbine foundations, interior boardings, stator, Exhaustdiffusoren, ND housing, Caddies, pontoon facilities, Austragsilo, pile coverings and much more ..

Heinrich Babylon in 1948 founded a water installation company that has been extended two years later to Bauschlosserei. Already in 1955, the local order frame was exceeded, so that first business links were established as a supplier of industrial plants.

This line of business has developed so cheap that they changed in April 1976 by the Viernheimer Blauehutstraße in the Zeppelin road in the industrial area four home where the operation still has its headquarters.

1976 The company founder died, and the company was transformed into a GmbH.

Babylon's daughter Inge, who incidentally learned the locksmith trade from the ground up and has the journeyman locksmith, and her husband Hans Stumpf introduced today the fortunes of the company.

With her son Heinrich Stumpf, in 1985 his master's examination took off, the third generation of the family in the company is now active.

We are a powerful and flexible medium-sized partner in all aspects of sheet metal work and mechanical galvanizing coating. Since 1888, we have steadily expanded our production depth and can now run with about 80 employees, both single and serial orders flexibly, quickly and with high quality. Short-term appointments are familiar terrain. Competent partners support us in many areas, such as electroplating and powder coating, with the same flexibility and quality.


In sheet metal processing, we can look back on decades of experience and have a powerful, modern machinery. We handle small, medium and large sizes (1500x3000 mm), folding is up to 4000 mm possible. Sheet metal parts are manufactured in every imaginable shape and of course with the highest precision. Laser cutting, edging, stamping, welding, and many other procedure we maintain. Metal spinning is another of our method.Even for simple work such as beading, beads and rounds we have the appropriate equipment. Applied welding processes are electrodes, MIG / MAG and TIG. The materials of black metal, structural steel, stainless steel (V2A, V4A) and aluminum are processed.
The production of sample parts and support to the production stage are also among our specialties. We offer reliability and quality of smooth sheet metal to finished coated and if necessary up to the mounted component at a high level. Of course, we are certified to ISO 9001:2000. Our quality management for all processes is continually evolving.

Our services in the field of corrosion protection are hot-dip galvanizing, Kleinteilverzinken and mechanical coating (Mechanical Plating, also known as a mechanical galvanizing). Our galvanizing plant is well equipped for galvanizing of large and small series as well as individual parts and small parts. The High-temperature has been proven for many types of small parts (stamping parts and threaded parts).The high durability of the products goes hand in hand with the excellent corrosion protection provided by hot dip galvanizing. Our success is based on the reliability and durability of our products, which are processed by the hot-dip galvanizing and mechanical coating. Mechanical coating is particularly interesting for small parts made of high-strength steels. We also offer the Almac coating. For further information and offers we like are available.

From prototypes through to series production: We offer you full service from a single source. From machining and additive manufacturing to eroding and laser cutting, we promise outstanding quality and on-time delivery.
