What is flatness tolerance in metal?
Related Terms
Tolerances
Tolerances define the allowable range of variation in a dimension — thickness, width, length, or flatness. Tighter tolerances require more precise processing and typically cost more.
Laser-Cut Blank
A laser-cut blank is a flat metal piece cut to shape using a fiber or CO2 laser. Laser cutting offers tight tolerances, clean edges, and the ability to cut complex profiles without tooling.
Plate vs Sheet
Plate is metal thicker than 3/16 inch (4.76mm); sheet is thinner. Plate is used for structural and heavy fabrication work; sheet is used for stamping, forming, and laser cutting.
Cold-Rolled Steel(CR)
Cold-rolled steel is processed further after hot-rolling by passing through rollers at room temperature. It has tighter dimensional tolerances, a smoother surface finish, and higher strength than hot-rolled.
