Quality assuranc

On the basis of our ISO 9001 quality management system, a constant improvement of our internal quality processes belongs to our daily business.

An early identification of faults enables us to quickly respond and guarantee a consistent high product quality.

Also, a sustainable development of our manufacturing processes as well as a most respectful treatment of our employees have a positive impact on WRW quality.

From the inspection of all supplied raw materials, to the manufacturing processes or the inspection of our multilayer pipes, we regularly measure and monitor our processes in order to provide our customers with first-class products.

For us, a thorough inspection of all received goods is indispensable. This is the only way we can guarantee that all raw materials correspond to our specific requirements thereby ensuring a smooth production flow and an optimal product quality.

Permanent control during the entire manufacturing process after each processing step enables us to respond quickly to any potential deviations. Thus, our customers profit from our top quality as well as our 100 % error-free products which are made in an environmentally friendly and sustainable way.


At the end of the life-cycle of our multilayer composite pipes, they can be recycled by a dry mechanical process. The recycled aluminium can be re-used while the remaining plastic mixture represents a good basis for fuel alternative. Provided that plastic composites can be separated again, the individual components can be re-used as recycled granulate material.

In order to create value for our customers and keep up-to-date to the latest developments, our staff are highly-committed and regularly attend internal training courses and special seminars in expert fields in order to broaden their knowledge.

Trust in the proven quality of WRW!
