Installation Notes

Sheet metal work should be performed by qualified tradespeople familiar with safe cutting and forming practices. Use appropriate tin snips, aviation shears, or a sheet metal brake when cutting or bending this stock. Always wear cut-resistant gloves when handling cut aluminum edges, as freshly cut sheet metal produces sharp burrs. When using this sheet for ductwork or flashing, follow applicable local mechanical and building codes for material gauge and fastening requirements.
