Exclusive Representation of KÖNIG + CO. GmbH
Since 2019, we have been the proud and exclusive representative of the German leader KÖNIG + CO. GmbH for the Slovak Republic. Through this partnership, we provide our clients with direct access to a world leader in the production of dished ends and special components that meet the strictest industrial standards.
We specialize primarily in the supply of dished ends in accordance with DIN 28011 (Klöpper heads) and DIN 28013 (Torispherical heads), which represent the technological standard for the production of pressure and non-pressure vessels, tanks, and industrial containers.

Key Pillars of Our Cooperation
As your established wholesale distributor, we build on four basic pillars:
- Certified Quality: We supply all components exclusively with a 3.1 material certificate according to EN 10204, guaranteeing declared mechanical and chemical properties.
- Regulatory Compliance (PED): Our products strictly meet the requirements of the European Pressure Equipment Directive PED 2014/68/EU, a key attribute for your safe production and subsequent certification of final equipment.
- Material Variability: We offer a wide range of stainless steels (e.g., 1.4301, 1.4404, 1.4571) and high-quality carbon steel P265GH.
- Logistical Availability: The current status of our stock, references, and technical specifications are fully available on our portal.
Our Values and Vision
- Professionalism: Our team consists of experts with deep knowledge of metallurgy and market trends.
- Flexibility: We constantly expand our range to respond to technological progress in engineering and energy.
- Partnership: We believe in a transparent approach. We are a partner you can rely on when planning small projects as well as large investment units.

Expertise Proven by Practice
At AC METALINOX, we believe that quality material must be backed by correct information. As we operate daily in the pressure vessel and industrial technology segment, we understand the strict legislative demands faced by your engineers and purchasers.
To facilitate your decision-making and planning, we have prepared answers to the most common technical questions related to our range and certification.
Frequently Asked Questions (FAQ) – Technical Standards and Certification
1. What exactly does compliance with the PED 2014/68/EU directive mean?
The PED (Pressure Equipment Directive) is a mandatory European standard for the design and manufacture of pressure equipment. Our components, especially dished ends, meet all the safety requirements of this directive, allowing you seamless integration into your certified pressure systems and guaranteeing operational safety.
2. What is the difference between a 3.1 and 3.2 certificate according to EN 10204?
By default, we supply materials with a 3.1 certificate, issued by the manufacturer, confirming that the delivered products comply with the order requirements (based on specific tests). If a 3.2 certificate is required, the material inspection takes place in the presence of an independent inspector (e.g., TÜV). We can arrange 3.2 certification upon agreement.
3. What are the main differences between DIN 28011 and DIN 28013 ends?
- DIN 28011 (Klöpper head): Has a shallower shape and a larger crown radius. It is the most common and economical choice for medium-duty pressure applications.
- DIN 28013 (Torispherical head): Has a deeper profile and higher strength for the same wall thicknesses. It is ideal for high-pressure vessels where optimal stress distribution is required.
4. Do you offer ends in materials other than stainless steel?
Yes, in addition to a wide range of stainless steels (1.4301, 1.4404, 1.4571), we also supply ends made of high-quality carbon steel for pressure vessels, such as P265GH, and heat-resistant steels according to your specifications.
5. What is the delivery time for special KÖNIG + CO. GmbH components?
Thanks to our exclusive representation, we have priority access to production capacities. We keep common dimensions in stock for immediate collection. For custom production, the lead time depends on the complexity of the geometry and current production load, about which we always inform you transparently in advance.
