At Weerulin, "Quality First" is not just a slogan – it’s our mindset. Weerulin follows a modern quality policy according to DIN EN ISO 9001:2015 and is regularly certified. For us, quality starts with the procurement of raw materials. These ensure the consistently high product standards that our customers expect from us.

Weerulin uses only the highest-quality raw materials. Our process monitoring ensures that the quality parameters are met during the production of our refractory products. Complete documentation guarantees the traceability of every batch produced. Our quality policy is dual, meaning that we adhere to the general quality standards of DIN EN ISO 9001:2015 and establish individual quality agreements with our customers.
