installation of the sculptures

Perpendicular Cylinders III
These steel sculptures are of the quality cor-ten which oxidizes to
a certain extent. This layer of rust protects the material against
further oxidation. The rugged appearance makes it possible to use
chains for hoisting these sculptures. Stainless steel can not be
handled with iron materials as it will contaminate the surface,
causing the rust to attach itself to the material, after which
it should be properly removed.
