First-class and modern machinery for sheet metal construction

Punching/Laser cutting

In addition to the traditional sheet metal punching machines, our fleet includes a fiber laser sheet metal processing machine. We actively work with the tool manufacturer to provide our customers with the latest innovations while saving on the overall cost of the product.


Our bending process is flexibly suited for production in small and medium sized series. We have a wide range of tools for different types of press structures according to the customer’s requirements.

Powder coating

Powder coating line with mix of automatic and manual painting satisfies the highest quality demands. Flexible and quick color changes ensures on time deliveries according to customer needs. Cleanness is of utmost importance to achieve high surface quality.

Welding TIG/MIG

Our robot and manual welding processes are certified according to ISO 3834-2. We have capability to weld structural and stainless steel. The welding process is performed by IWE/IWS qualified staff with many years in the industry. Production facilities and lifting equipment can handle welded structures of up to 500kg.


We offer complete as well as partially assembled products where HANZA is responsible for testing, configuration and optimization of the entire product flow. The majority of the components are manufactured in our own factories and the remaining parts are sourced-in. Here, our customers benefit greatly from our global supplier network, constantly benchmarked by our sourcing department.


We have extensive experience of handling the entire supply chain, including warehousing, with deliveries directly to our customers’ customers and markets.


We help you with the development of prototypes and to facilitate a transition to series production. Prototypes are configured for immediate volume production. We also offer simulations before prototype production, guaranteeing that the details are viable.

Professional and committed staff

Our committed employees are the beating heart of the company, and their professional attitude permeates our business. Skilled colleagues who accept the challenge of finding solutions for better metal constructions drive development forward.

Quality development at HANZA

Product quality is one of our customers’ main priorities. Therefore, we constantly monitor their varying parameters and wishes by investing in quality development according to the LEAN method. Our sharpest analysts and professionals put extra time and resources into this important area.

Great synergies in cluster manufacturing

The factory’s various production technologies as well as logistics and procurement services make it possible for our customers to buy versatile manufacturing packages from one single supplier. This reduces the customer’s total costs and shortens lead times, while at the same time reducing the  carbon footprint.


The right certifications for production are crucial

All HANZA factories hold a variety of certifications adapted to the business and technology in which they operate. The certificates complement our ambitious protocols for reduced environmental impact, data security, work environment and product quality.
