Inner and outer diameter
Inner Diameter | 300、400、500（Customized according to the customer's machine size） |
Outer diameter | The outer diameter range is determined based on the width of the material required by the customer and the maximum weight of a single trailer. |
The weight of a single trailer generally does not exceed 2 tons to ensure that the goods will not be damaged during transportation and moving.
Surface
DSM offers a variety of different surface treatments for stainless steel plates. There are1U, 1C, 1D, 1E, 2B, BA, No.4, TR, HL etc.
Edge:
The edge of the steel strip is trimmed, and the burr height is 10% mm. If there are special requirements for the edge, it can be scraped.
