Appa­ra­tus & tank construction

The pro­per­ties of appa­ra­tus and con­tai­ners are always based on the stan­dards and requi­re­ments of the respec­ti­ve indus­tri­al sec­tor. We imple­ment the indi­vi­du­al spe­ci­fi­ca­ti­ons of our customers.

Indi­vi­du­al appa­ra­tus and tank construction

With our expe­ri­ence and tech­ni­cal equip­ment, we are able to meet the chal­len­ges in appa­ra­tus and tank con­struc­tion in a fle­xi­ble and solu­ti­on-ori­en­ted man­ner. In order to ensu­re the safe and pro­fes­sio­nal use of the appa­ra­tus and con­tai­ners, we com­ply with the indi­vi­du­al spe­ci­fi­ca­ti­ons, which are inspi­ra­ti­on, moti­va­ti­on and obli­ga­ti­on for us. We value mutu­al exchan­ge. The fact that we are allo­wed to deve­lop sui­ta­ble solu­ti­ons for a wide varie­ty of indus­tri­al sec­tors, from che­mi­cals to food­s­tuffs to ener­gy tech­no­lo­gy, pres­ents us with gre­at chal­len­ges time and again, in appa­ra­tus and tank con­struc­tion. Our expe­ri­ence and exper­ti­se in all aspects of stain­less steel flow into every project.
