Technical information

For a good galvanisation result, the materials delivered to Verzinkerij Heerhugowaard must satisfy a number of conditions:

• materials must have the correct steel quality;
• inlet and outlet holes must have been made in the correct manner;
• materials must be free of impurities that cannot be removed by chemical pretreatment.

That means materials must be free of:

• paint and/or varnish (or traces);
• welding sprays that are too thick or contain silicone;
• welding slag;
• thick oil and/or grease layers;
• marks with pastel crayon, paint or inappropriate markers (consult galvanising plant);
• adhesives, glues, stickers etc.

Specific requirements apply for the materials that are also going to be powder coated. For a good result and a long service life of the coating it is important that the substrate is free of sharp edges and burrs. The smoother the substrate, the better the result.
