Production Information : HEGESZTETT ÉS VARRATNÉLKÜLI ZÁRTSZELVÉNYEK
Hegesztett és varratnélküli zártszelvényeket elsősorban raktárról kínálunk Partnereink részére S235, S275, S355
minőségekben, gyors beszerzési határidővel. Természetesen gyártásból is betudjuk szerezni ez esetbe viszont min. 24
tonna rendelési mennyiséggel kell számolni, hegesztet zártszelvények esetén gyártásból akár 2 hetes határidővel, egyedi
hosszakban is letudjuk gyártatni. Specialitásunk a vastag falú valamint az S355, S355J2H minőségek zártszelvények raktárról
történő beszerzése.

The advantage of steel tubes for precision applications is the high precision of their manufacturing, the good quality of their surface, and the guaranteed mechanical and technological properties. That is why the pipes are widely used in the machining industry and in the automotive industry. Welded pipes for precision applications are manufactured in the process of cold drawing.
