Industrial Perforated Metal Plate Screens - Surface Finish and Cleanliness
Surface characteristics of Industrial perforated metal plate screens
Slight damage of the perforated metal plate by mechanical action during the perforation process cannot be excluded. If this is detrimental to the proposed use, the purchaser should consult with the manufacturer before ordering.
Perforated metal plates are usually supplied with a light oily film. There should be no excessive seepage of oil after stacking.
Degreased perforated metal plates, e.g. prepared by solvent or steam treatment, may be supplied by agreement. Degreasing is inappropriate for plates of low-carbon steel unless subsequent protection against corrosion is provided.
