A. SHEET SIZES
Dimensions: Plain undecorated metal and metal laminates
Mat'l Dim. Inches 48" x 96" or 48" x 120"
Mat'l Dim (mm) 1219 x 2438 or 1219 x 3048

Dimensions: Custom GageMetal
Mat'l Dim. Inches Any size up to 48" x 120"
Mat'l Dim (mm) Any size up to (1222 x 3048)

Specifiers should consider the most economical use of these standard sizes before designing a project. If the intended metal facing has formed edges, the overall standard blank size should always fall within the above dimensions.

B. METAL COLORS, TOLERANCES, VARIANCES
Any metal surface, plain or laminated, may show very slight variances in the color of the alloy, from sheet to sheet. If this variance is virtually absent in most aluminum alloys it does exist more often in Stainless Steel sheets and more often still in Copper alloys.
These variances have their origin in production methods and batch mode production in the steel mills. Highly structured design patterns or rough type textures are often the best way to overcome such variances. A specifier should establish some parameters of acceptable tolerances when this is important.
