2.4 SHEET METAL FLASHING FABRICATION<br />
A. Field Measurements: Where sheet metal flashing is to fit, cope, or be tailored to other<br />
construction, check actual dimensions of other construction by accurate field measurements<br />
before fabrication of flashing.<br />
B. Fabrication Procedures:<br />
1. Shop form flashing on a bending brake.<br />
2. Shape, trim and hand seam on bench as far as practical with proper tools.<br />
3. Form exposed Work without excessive oil canning, buckling, gnd tool marks and that is<br />
true to line and levels indicated.<br />
4. Make angle bends and folds for interlocking metal with full regard for expansion and<br />
contraction to avoid buckling or fullness in metal after installation.<br />
5. Form materials to shape indicated with straight lines, sharp angles and smooth curves.<br />
6. Fold and hem exposed edges of flashings.<br />
