Below we describe the different environmental classes that occur where the products are assembled. The corrosivity classes are according to SS_EN ISO 12944-2 and taking into account the corrosivity of the atomic sphere and environmental examples.The examples below is typical environments in the tempered climate zone (informative).
Lifespan of the surface treatment
Below is a calculation of the lifespan of the surface treatment until red rust appears on the surface. Average etching per unit area and one-sided thickness reduction - one-year exposure.
| Corrosion class | Steel | Zink | ||
| Average etching (g/m2) | Thickness reduction (μm) | Average etching (g/m2) | Thickness reduction (μm) | |
| C1 | < 10 | ≤ 1,3 | ≤ 0,7 | ≤ 0,1 |
| C2 | > 10 – 200 | > 1,3 – 25 | > 0,7 – 5 | > 0,1 – 0,7 |
| C3 | > 200 – 400 | > 25 – 50 | > 5 – 15 | > 0,7 – 2,1 |
| C4 | > 400 – 650 | > 50 – 80 | > 15 – 30 | > 2,1 – 4,2 |
| C5-I | > 10 – 1 500 | > 80 – 200 | > 30 – 60 | > 4,2 – 8,4 |
| C5-M | >10 – 1 500 | > 80 – 200 | > 30 – 60 | > 4,2 – 8,4 |

Product managers
Mats Sixtensson
Mats is part of our team since March 1, 2024, after working in product development at a major company in aluminum processing. In his current role as Product Development Manager, he enjoys the familial atmosphere and the wide range of products.In his free time, he enjoys playing golf and loves working on and ride his classic Italian scooters. But his interests also extend to building things, which can range from electrifying a longboard to building his own CNC machine. Mats doesn't have a specific favorite artist, but he enjoys listening to rock music to get in the right mood.
When it comes to dream destinations, the choice is easy for Mats - Croatia. There, the sun, the sea, and the opportunity for snorkeling appeal to him the most.
Johan Petersson
Johan Petersson has been part of MP bolagen since the fall of 2010. His area of responsibility is export and that includes offers and support to retailers, but he is also responsible for product development within electrical products. What really distinguishes Johan's experience at MP bolagen is the strong teamwork with his colleagues, who are always there for each other.
In his free time, Johan divides his interests between two important activities. First and foremost, as a leader in his son's soccer team, he spends a lot of time supporting and developing young talent in the sport. In addition, he is a devoted spectator when his daughter plays soccer. In addition to soccer, Johan also tries to catch up on some golf games when opportunity gives.
When it comes to music, Johan has no specific favorite song to name. But one thing that really means a lot to him personally is his commitment to soccer. He is actively involved in a soccer club called Vetlanda FF, where he not only is as a leader but also a part of the club's board. For Johan, soccer is more than just a hobby, it is a commitment and an opportunity to be part of something bigger.
Patrik Hillström
1990 was the year Patrik Hillström was employed at MP bolagen, so he has been on a fantastic journey over the years. He has tried the role of salesman, but now Patrik is responsible for product development of our steel products such as cable ladders etc.
It is a well-managed company that is not afraid to develop and invest, he thinks.
A bit of a training junkie with a lot of focus according to colleagues, but also someone who likes outdoor life.
He don't have a direct favorite destination, but a trip with the cab is never wrong. Best is still a beautiful sparkling winter day on the ski track, which is hard to beat, says Patrik.
