Tin snips or a "nibbler" type electric tool are recommended for field cutting metal panels. Cutting the steel generates slivers
or metal chips. These slivers and metal chips must be immediately removed from the panels because they will damage the
finish and shorten the life of the product.
One method of preventing this problem is to flip the panels over when cutting. This allows the slivers and metal chips to be
brushed from the back side and avoids damaging the paint on the top side of the panels.
When cutting metal panels and flashings, goggles must be worn for eye protection.
CAUTION
All product surfaces should be free of debris at all times. Installed surfaces should be
wiped clean at the end of each work period. Never cut panels over metal surfaces.
Metal shavings will rust on the surface, voiding the warranty.
All painted panels and flashings have a factory applied baked on finish. Handling and installing panels may result in some
small scratches or nicks to the paint finish. Touch-up paint is available in matching colors from Metal Sales. It is recom-
mended that a small brush be used to apply touch-up paint to those areas that are in need of repair. Touch-up paint does not
have the superior chalk and fade resistance of the factory applied paint finish and will normally discolor at an accelerated
rate. Aerosol paint should not be used because of the overspray that may occur.

Proper design and installation of vapor barriers and ventilation systems are important to prevent condensation and the result-
ing problems of moisture damage and loss of insulation efficiency.
Condensation occurs when moisture laden air comes in contact with a surface temperature equal to or below the dew point of
the air. This phenomenon creates problems that are not unique with metal buildings; these problems are common to all types
of construction.
The underside of the metal roof on a typical metal building (no attic) should be protected from condensation by insulating
with a faced insulation. This should reduce the potential of condensation forming on the underside of the panels.
On buildings that have an attic space or are being retrofitted with a metal roofing system, vents should be placed at both the
eave and peak of the roof in order to prevent a buildup of moisture (humidity) in the attic space.
