Notes:
1. A hyphen sign in the table (-) means that the sheet cannot be used at the relevant range.
2. Generally a span of less than 600 mm (24 in.) is impractical for this installation configuration.
3. The lowest radius that appears in the upper row of every sheet group in the table is the minimum permitted cold bending radius for that specific sheet type.
