Plates
LONGITUDINALLY PROFILED PLATES
Longitudinally profiled plates (also tapered plates) are plates whose thickness varies along their longitudinal axis, with the thickness variation reached by continuous adjusting of the roll gap when the material passes through the roll stand. Longitudinally profiled plates can generally have linear or non-linear thickness course.
Tapered plates are used especially for various types of steel structures where their usage results in considerable economical savings (structure weight reduction, reduction of welded joints, etc.)
In order to reach as much economical contribution as possible, and easy application in all steel structures, various shapes of tapered plates consisting of several tapered and flat segments can be manufactured and used.
Tapered plates are manufactured of steel grades according to the standards EN 10025-2 and EN 10025-3.
The dimensional standard applicable for longitudinally profi led plates is VN 425321.
