The main steel grades that JK buys from SSAB are Strenx® 700 CR, Strenx® 700 MC, Hardox® 400 and Hardox® 450. In order to handle the new steel grades, JK purchased state-of-the-art machines for cutting and bending, as well as new welding trucks. Some of the trucks are semi-automated.
Scandinavian customers quickly realized the benefits of the new containers. They are lighter and stronger than the other makes and can take up to one tonne more per load. Along with their more streamlined shape, they offer fuel savings during transportation of around 14%. Thus the profits are both environmental and financial.
Today 90% of all containers manufactured by JK for the Scandinavian market are light containers made from SSAB high-strength steel. The Polish company is also a member of the two SSAB customer programs: Hardox® In My Body and My Inner Strenx®.
For JK, the idea had always been to sell new light containers for the same price as the traditionally heavier ones. And it worked out well: the high-strength steel is slightly more costly but on the other hand less steel is needed to build a container and involves a simplified production process.
CEO and owner Milosz Kiedrowski had been with the company for five years, when his father, Janusz Kiedrowski, who established the company in 1988, unexpectedly passed away in 2016. After the tragedy, he had to take over leadership of the company immediately.
He has managed well. Production has risen from 11,000 containers in 2015 to 15,500 in 2017, but still cannot keep pace with demand from both Polish and foreign customers.
