Cold Rolled Steel Sheet Thickness Tolerance

Width governs the tolerances both width and thickness for rectangle bars.

Cold rolled steel sheet thickness tolerance.

Tolerances shown are for 48 wide sheets. Per square foot per inch thick. Preferred thicknesses are shown and are intended to indicate which gauges are more likely to be available on an ex stock basis from suppliers. If the bar is 1 5 thick x 3 5 wide the width tolerance of 0 006 will be the tolerance for the thickness as well which is 0 006.

We work with nominal thicknesses so it s important to know the thickness tolerance on the material you chose in order to know if the final product will be suitable for your application. This standard is designed to bring together tolerances for cold rolled narrow and wide strip. It has officially superseded en 10258 and en 10259 although of course customers and suppliers are entitled to continue to use these standards. Standard tolerances for cold rolled steel usually choosing material thickness is one of the first steps a designer takes when starting a project.

Weights are based on ordered thickness at 41 82 lbs. Likewise consider aluminum where minimum weight and or corrosion resistance is a consideration. Protocase recommends cold rolled steel for general purpose enclosures. Tolerances to bs en 10259 for cold rolled wide stainless steel strip thickness tolerance.

If corrosion resistance is required consider galvanneal stainless or aluminum. It offers a good combination of cost and structural integrity stiffness.
