Anti-corrosion coated steel is steel coated
with a layer consisting primarily of zinc
plus another metal, such as aluminum or
magnesium.
After it is cut, mild corrosion develops initially
at the cut surface, but then the components
of the coating layer dissolve to form a stable
protective layer over the cut.

PO INTS TO CHECk bEFO RE I NSTA LL ATION WORk
• The solar modules generate electricity when exposed to sunlight, so be careful not to short circuit the output cables.
If shorted, the cables can become overheated and their cable sheaths can melt.
• Stop working when the surface of the roof is wet. There is a danger of slipping, falling, and shock.
• Never step or sit on the glass surface of the solar modules. The glass may break.
• Do not twist the solar modules when you mount them (twisting should not exceed 0.1" per 4"). Failures and damage
can result.
• When you mount the solar modules on the rail, never allow an output cable to become caught between the rail and a
module frame. Short circuits and fire can result.
