3.7. UNITIZED CLADDING SYSTEM
 Developed to construction the Ecorium roof shown below.
 Manufactured at the factory and assembled in the field.
 Minimizes the errors that can occur in the field work, so the construction quality is excellent and
the construction period can be shortened.
 More complex shape, more effective with this method.
