Webglas GC
Overview
Webglas GC (GC = gel coated surface) is proving its worth in buildings where
steel and other roofing or wall cladding materials deteriorate or corrode at an
unacceptable rate. The sheet weight is 3660 grams per square metre and is
reinforced with a heavy gauge woven glass mat which provides continuous strength
and protection in every direction. The overall strength is such that wire
safety mesh is not required. This is a particularly important benefit in
chemically aggressive and corrosive environments where safety mesh is eroded and
traditional steel cladding quickly deteriorates.
Webglas GC also features the Ampelite’s Gel Coat technology.

"Webglas GC"
Polyester resin base sheet with Isopthalic NPG Gel Coated surface.
Continuous woven mat reinforcement.
"Webglas GC+"
Vinylester resin base sheet with Isopthalic NPG Gel Coated surface.
Continuous woven mat reinforcement.
All resins are UV stabilised and acrylic modified to provide excellent
weather resistance. If cleaned regularly the sheeting retains its original
bright appearance over many years.
Both products withstand environments that corrode or destroy metal and many
plastics in a short period of time. Webglas GC+ provides additional protection
where there are high concentrations of alkalines or
acids.
