INSTALLATION GUIDELINES
14" & 24" ALUMINUM TRIM COIL
Cutting Trim Coil
Trim Coil can be cut with tin snips or aviation shears for short or curved cuts. For longer straight cuts, use a utility knife to score
the coil, then bend the coil back and forth on the score line until it breaks.
Installation Guidelines
• Applying trim coil is like hanging a cover over structural piece, not laminating a skin-tight surface. Allow for irregularities in the
wood as your metal trim shapes will be straighter than the wooden pieces you are covering.
• Aluminum expands and contracts with the temperature drop. Custom flashings or trim, especially longer ones, must be able to
move slightly. Failure to allow movement can result in bulging or buckling when the temperature changes.
• Allow approximately 1/16" space between the ends of shapes and structural objects, such as the walls and inside corners.
• Nail shapes into place using painted aluminum trim nails. Drill oversized nail holes and do not nail too tightly. Nails should
penetrate the wood a minimum of 3/4"
• Never face nail fascia shapes.
• Bending a hem on the edges of flashings will increase their strength and help assure a straight edge.
• Be sure that any joints are overlapped to shed water.
• Aluminum trim coil should not be used locations subject to standing water.
• Do not install aluminum flashings and trim in a corrosive environment. Avoid direct contact with corrosive materials
or dissimilar metals.
