The flatness tolerance of of strip sheet plate and cut length shall not exceed 10mm for normal cases and 7mm where a special tolerance fs is required for length 3000mm and 12mm for normal cases and 8mm where a special tolerance fs is required for length 3000mm.
Cold rolled steel sheet thickness tolerance.
Weights are based on ordered thickness at 41 82 lbs.
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.
It offers a good combination of cost and structural integrity stiffness.
In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish.
However the range of tolerance on hot rolled sheet is much wider than the range found on cold rolled sheet.
Protocase recommends cold rolled steel for general purpose enclosures.
Likewise consider aluminum where minimum weight and or corrosion resistance is a consideration.
This is identical to the requirements of en 10259.
Both types of steel sheet have tolerance ranges.
The range of the tolerance minimum thickness to maximum thickness in each gauge range decreases as the sheet material becomes thinner on its nominal or mean thickness.
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.
Hot rolled steel sheets are available in the range of 1 6 mm to 10 mm thickness.
Whereas cold rolled steel sheets are available from 0 1 mm to 4 mm thickness.
The flatness tolerance of of strip sheet plate and cut length shall not exceed 10mm for normal cases and 7mm where a special tolerance fs is required for length 3000mm and 12mm for normal cases and 8mm where a special tolerance fs is required for length 3000mm.
In cold rolling steel sheet is cooled at room temperature after hot rolling and is then annealed and or tempers rolled.
If corrosion resistance is required consider galvanneal stainless or aluminum.
