Plates
Information
The plate rolling mill was founded in 1971 and underwent extensive modernisation in 1999, which permitted a significant improvement in the geometry of rolled plate, surface quality and expansion of range. Plates are manufactured from continuously cast slabs.
The range of plates is rolled in thicknesses 5 – 100mm (200mm) and widths 1000 – 3200 mm.
The quality range has these applications of use:
ocelové a mostní konstrukce
lodě
dopravní stroje a vozidla
otěruvzdorné plechy
tlakové nádoby užívané za normálních i zvýšených teplot
speciální vojenská technika
plechy odolné proti atmosférické korozi
tvarové výpalky

Plate marking
Plates are marked by stamping and with paint. In the case of cold stamping of plates (four-high), the plates are stamped using the low-stress spot method. In the case of manual stamping (two-high), it is necessary to agree on the low-stress method in the order. The plates are marked with white paint on automatic signing machines or manually (usually using templates). A specific requirement of a customer for marking of plates with text (spraying white paint on plate) or colour marking is implemented after agreement as part of each individual order. The Colour Marking Catalogue containing the individual patterns is available to make the choice of colour marking easier.
