On 1 November, the senior boss Dieter Kranenberg takes his well-deserved retirement as part of the generational succession. Thorsten Kranenberg is now the sole shareholder and managing director.

In October, WIEHLSTAHL provides itself with planning security for future expansion measures at the proven location in 51674 Wiehl by purchasing a plot of land of approx. 1,500 sqm. The fully developed plot borders directly on the south side of the previous company premises.

In March the re-audit for certification takes place. With the certificate according to the new standard DIN EN 9001:2008 WIEHLSTAHL is certified that the quality management system is successfully implemented and lived.

At the end of September the ground-breaking ceremony for the new building project "Hall 3" takes place, with which WIEHLSTAHL will increase the storage capacity by approx. 40%. For the first time, a 10-ton crane will be used in order to be able to fulfil customer requests for larger workpieces in the future.

Thorsten Kranenberg joins the company. The future of WIEHLSTAHL is secured.

In January 2004, WIEHLSTAHL expands its extensive bright steel range by moving into a newly built additional warehouse.

The team now consists of 12 people. With several saws and three crane systems, fast and reliable order processing is always guaranteed.

Thanks to the traditionally grown high-quality steel stock and the consistent steady expansion of the range of materials, customers are supplied mainly from stock.

The successful introduction of a quality management system at WIEHLSTAHL is documented by the certification according to DIN EN ISO 9001/2000.
