Fabrication Tolerances for Dimensional Variance in Sheet Metal and Machined Parts
Standard Tolerances For Perforated Sheet Metal
Perforated metal is any type of sheet metal that has a pattern of holes punched into it. This makes it useful for controlling the passage of air, light, liquids, and even sound. Perforated sheet metal is most commonly used for ventilation and filtering.
