Fire-Rated Board Systems
Are fire-rated boards suitable for
circular steel members?
Fire-rated boards can also be used to
clad circular steel members and any
other non-standard steel members.
Architectural Treatment
a) Corner Reinforcement
Corner beads made of rigid vinyl
create a rust-proof, dent-resistant
finished corner. The exposed nose of
the bead helps to prevent damage
from impact and provides a screed for
fi nishing. It provides a key for the jointing
compound and eliminates shadowing
and edge cracking.
b) Control Joint
The purpose of the control joint is
to relieve stresses of expansion and
construction across the joint in large
wall areas. Materials such as rolled
formed zinc with perforated flangers
may be used for this purpose.
c) Joint Compound
All purpose ready-mixed joint compound
may be used.
