Fabrication
Mechanical and surface characteristics
MECHANICAL PROPERTIES
KASIGLAS® manufactures the final parts. Depending on the part geometry, it may require forming before coating or after coating. This is evaluated on a case-by-case basis and confirmed by KASIGLAS®.
Note: Coated sheets can be drape formed after coating.
