Our Quality

In Turkish DemirDöküm factories, quality systems are applied within a comprehensive process from raw material/material entry to subsidiary industry assessments, from production to control at shipping point. In production, all employees undertake quality responsibility as a principle with OPF (one-piece-flow) technology, in addition to the control methods such as 5S, FMEA, 6 Sigma, Kaizen, and SPC.

In all production processes realized at our plants, protection of the environment is the main input. Heat exchangers of wall hung boilers and gas water heaters are coated with water-based aluminum dye, non-hazardous to environmental and human health. Technological and domestic waste water produced at factories are biologically and chemically refined at developed treatment plants and solid wastes are disposed in accordance with the regulations.

In this context, both our products and plant have quality conformity certificates valid both in Turkey and in the world. Our plant in Bozüyük is the first establishment to obtain the first ISO 9000 certificate in Turkey.

Export

DemirDöküm, which initiated its export activities in 1968 by selling cast iron radiator to Jordan, exports to more than 40 countries on a geography extending from China to Chile with its broad product range. We aim at establishing long-term cooperation with our partners in the countries we export to, and carry out our activities within a structure indicating the power of our brand also in these markets.
