b. Type • Smooth Surface
• Rough Surface
During manufacturing, the side of
the wall facing the conveyor belt
will produce smooth surfaces,
while the side exposed to the air
will produce rougher surfaces.
c. Other
Considerations
• Smooth-faced surfaces are
marked by an arrow on the shop
drawing
• Smooth-faced surfaces are often
specified to face the external, so
as to decrease the amount of
finishing works to be done
(hence decreasing scaffolding
works)
