Remark: |

|
1. Tolerance is according to DIN Length: ﹢0~3 %, width: ﹢0~ 3%. |
|||||||
|
2. it is theoretical value for above spec, with the 1000 x 1000 mm, also we can supply width 10mm ~ 2000mm, Length 1000mm, 1500mm, 2000mm, and more. Thickness 0.1mm ~ 8mm we can Roll. |
|||||||
|
3. Taking objective as standard, listed data are for reference only. |
|||||||
|
4. The products above have been strictly treated with tempering; the strain value has met the minimum. |
