Welcome to our company page!

We are a small family business that deals with many activities.
We manufacture steel platforms, welded constructions, roofs, railings, handrails, steel components, stainless steel (predominantly 1.4301) and aluminum alloys. In addition, with our machine park, we are also able to carry out small series as well as single part production in turning and milling work.
Recently, we have been accompanied by a flame cutting machine, with the help of which we can also produce thicker plates independently and at short notice.

Laser and bending work are no problem for us and our neighboring companies, which means that sheet metal working is also possible.
We are also happy to take over 3D CAD work and can thus offer you an all-inclusive package. :)

If you have questions about our company or our further activities, do not hesitate and write or call us.

Greetings from the company Schmid!
"Do it!"

Ladies and Gentlemen

I have a small business for welding and assembly manufacturing.

From January 2023 I will start as a master metalworker.

After the master craftsman, the small business should then be re-registered as a large business.

Company specialized machinery:
- Development and construction of devices and special machines for automation of manufacturing and assembly processes
- 3D CAD / CAM assisted design / programming
- Mechanical production including 3D-shaped parts
- Own Steuerungsbau
- Installation and commissioning of machines worldwide

Division production:
- Welded parts and compl. Welded assemblies to 10,000 kg per piece.
- Items & series production to robot welding system.
- Quality welding to DIN 18800-7 class E (large welding certificate) with extension to dynamic range.
- Verification of suitability for welding of rail vehicles and vehicle ponents according to DIN 6700-2 component class C2.
- Quality Management System according to DIN EN ISO 9001:2000

Process-integrated solutions and products Schweißbau Handling

We develop, design and produce in terms of process integration with creative solutions in the areas Schweißbau and products handling. Among process integration we mean a procedure that includes the complete manufacturing and logistics process. Expensive, time-consuming and quality-reducing interfaces, oversizing and subsequent operations are largely avoided. We act workpiece in the gram range as certain as large parts weighing up to 15 t. Series parts in reproducible quality are possible as well as 1 piece solutions. All processing steps, we also offer as a contract manufacturer.

Competence in welding of complex parts or assemblies
• Large qualification class E in accordance with DIN 18800 Part 7, expansion to high-strength fine-grained steels, as well as the certification according to DIN EN ISO 3834-2
• Many years of experience in the item-manual welding and mechanized series welding (MIG, MAG, TIG)
• High precision complex weldments
• we weld leak tested hydraulic cylinders, containers and distribution
• Separate welding engineer in the house

Large parts - Precision
To make the entire production process of a welding assembly or handling device from a cost, quality and schedule aspects optimally, we have modern equipment for machining. Our machining centers are equipped with up to 60-fold tool changer. Herewith we can with a size of up to 8 m x 3 m x to edit parts of 1,5 m and a weight of up to 15t. Also as a contract manufacturer we provide these processing options hesitate to

coating
To make the entire production process of a welding assembly or handling device from a cost, quality and schedule aspects optimally, we have a painting. This is configured and adapted to paint parts up to 12 m length for 1K and 2K liquid coatings. As a contract manufacturer we provide these editing options at your disposal. In powder coatings and other methods of surface treatment, we work with companies rennomierten surface technology.

• Complex machining, painting and assembly of components

The individual company stufenvier was founded in 2017 as an engineering office for welding technology and occupational safety. We have continued to develop to this day. The change of name to stufenvier GmbH was followed by the establishment of an in-house welding production facility.

We are currently in the development process of our own product line. From the beginning we have focused on long-term business relationships with our customers. We achieve this by building mutual trust, high-quality work results and economical work. Constant commitment, innovation and creativity enable us to solve even challenging tasks together.

We are happy to accompany you on your way in all welding processes and consider every stable partnership with a company as the basis of our success.

Our core competence is the machining and manufacturing of machine parts. We combine experience with inventiveness and thus offer innovative solutions in the field of mechanical engineering. The path from the first idea to the finished product is characterized by reliability and precision.

We support and competently support our customers in solving their concerns and tasks. We are happy to take responsibility for the manufacture of high quality and marketable products.

We work with regional companies as well as international groups from the areas:
Medical technology, motor technology, plant engineering, energy technology, railway technology and high voltage technology

We have continued to expand our experience and can now benefit from a solid foundation for the constant expansion of our product portfolio.

The Schulz Conveyor Systems GmbH with its seat in Gräfenroda was founded by Mr. Peter Schulz 1991st Immediately after the foundation began to invest in the latest technologies. Aided by the laser cutting technology, which had its technical breakthrough early 90s, the clientele, and thus the company grew rapidly. Within just a few years on the former site of an old glass factory an advanced sheet metal manufacturing. After the laser technology also held technologies such as the folding and welding feed.

In 1997, Schulz conveyor systems GmbH took over part of the Gothaer Fahrzeugwerke. Thus opened up for the company, a new line of business - the automotive industry.

Today the company Schulz conveyor systems GmbH is a solid medium-sized company, which adapts through a flexible, broad-based manufacturing processes and the rising and volatile market conditions and requirements.She specializes in the manufacture of welding and assembly, as well as laser and metal parts.

To continue in the future success of the company in the usual manner, the following business objectives:
Ausbau and consolidation of market position
Fertigung highest technical level
Lieferung best quality
Automatisierung manufacturing
Erhöhung of technical, professional expertise to assist customers with constructive issues and cost reduction
Erhöhung production depth

We specialize in thermal protection tubes, thermowells, static mixers, pressure vessels, heat exchangers and tube coolers. We have an approval acc. ASME Section VIII Div.1 (Certificate No .: 54.838 - 27.03.2018) and are accordingly approved Stamp-Holder. Likewise, we are approved manufacturer for defense technology products acc. DIN 2303 and are approved for the manufacture of pressure equipment cat. II module A.
