The cataphoresis process requires a conside-
rable and sustained expenditure. However,
it goes without saying that the finish is su-
perior and ensures greater safety in relation
to the process of galvanization and electros-
tatic painting. For over 30 years, Mecalux
has applied this process to the uprights their
racking frames consist of, due to their criti-
cal importance in any installation: they are
subject to interior microclimates, in contact
with the floor, bear heavy loads, can suffer
blows, etc.
The anti-oxidation strength of cataphoresis
is much higher than other finishes on the
market, as can be seen in the comparative
chart. u
The finishing process
that Mecalux applies
to its components
is based on the use
and the performance
requirements
