Dear business partners,

since 13 July, there have been storms and heavy rain in Hagen, especially at our Sedanstraße site, which have already led to massive damage, material failures and plant downtimes at this plant. Due to these floods, we are no longer able to deliver for the foreseeable future. For the time being, we will not be able to receive deliveries of input materials or carry out material shipments from this location.

Massive delays in the delivery of your orders are therefore unavoidable

Naturally, we have no influence on these external events, which we could neither avert nor make harmless by exercising reasonable care. We therefore feel compelled to declare force majeure as a precautionary measure and to inform you of impending delivery disruptions, the extent of which we are currently unable to foresee.

We will of course inform you promptly about the effects on your specific orders, but we would like to ask you to refrain from individual enquiries about the delivery status for the time being

Thank you for your understanding.

HDL Surface Coating

Developing durable solutions which persuade the customer.

Strip galvanization is a well-known process. But if its potential is to be explored and developed further, there must be a willingness to repeatedly initiate innovative working processes, which must be aimed at the continuous improvements and their implementation throughout all departments within our company. In order to steer this process in an operative mode we have to cultivate the collaborative cooperative relationship with our customers and suppliers. The only way to find solutions and help all of us to make one more step forward is to always keep close contact with our customers and suppliers. Central to this is the electro- galvanization and variously post-treated precision steel strip, with its finished surface, which can be applied in a variety of ways. To ensure an optimal working process, we collaborate jointly with our customers and determine the specified parameters of the carrier material and also the properties of the surface in order to produce our high-grade HDL- band on our three galvanizing production lines.
