Optimum surface pressure


We manufacture washers made from customary materials with detailed labeling. So, we close the gap to the requirements of the Directive 97/23 / EC (PED). Our washers of the MMD-W series are labeled with regard to manufacturer's trademark, nominal size, material and batch. We have developed the MMD-W with a larger outer diameter. This allows visible marking after installation and thus is a very useful method for installation inspection.


A special product is the MMD-W-CP (Form 2). It is a washer with drainage grooves and has already proven itself in non-encased systems. It prevents or reduces the corrosion caused by rainwater to lower bolt holes with horizontal or oblique flange applications in ascending / descending lines.
