A surface treatment can be very useful. For example, to improve the longevity of your perforated sheets or the appearance. At Fahl Lochbleche, you can choose from various finishing methods: In addition to machine degreasing, perforated sheets are galvanized, hot-dip galvanized, electrolytically polished or plastic powder-coated on request.
perforated sheets are available galvanised, oiled oder hot-dip galvanised
Without further information, perforated sheets are not galvanized, but only lightly greased. That is, the sheets are afflicted with a tactile and visible oil or fat film. Alternatively, degrease with an oil binder. With oil binders we achieve a relatively grease-free surface. However, residues remain in the holes. For a completely grease-free surface we recommend machine degreasing. However, this method is only suitable for stainless metals.
you can order your metal sheets:
- hot-dip galvanised
- electolytically polished
- plastic powder-coated.
Perforated sheets are not only avaliable galvanised, but also as hot-dip galvanised. In the case of subsequent hot-dip galvanizing, the perforated sheets are galvanized by immersing them in a molten zinc melt. If perforated sheets are galvanised in the way, they can then have a rough, grainy surface. In addition, the hole diameter should be more than five millimeters, otherwise the holes can be clogged.
