Stainless steel
After finishing a stainless steel construction, it is important to treat it. On the one hand to remove the weld discolouration, but especially to prevent the workpiece from rusting.
Sofel has a range of products for degreasing, pickling and neutralising so that a perfect passivation of the workpiece is obtained.
Corten steel
Corten steel is a metal alloy consisting of iron to which copper, phosphorus, silicon, nickel and chromium have been added.
The rust-coloured and very dense oxide skin of Corten steel shields the underlying material from oxygen, which greatly slows down the oxidation. However, a disadvantage is that the rusting process still takes several months.
Sofel has developed products to accelerate the rusting process, to stop the rusting process and to fix the rust layer.
Aluminium
Pickling aluminium is, just like stainless steel, a very important surface treatment to ensure good corrosion resistance or as a pre-treatment for the painting process.
Sofel offers products to degrease and pickle as efficiently as possible, so that the aluminium can passivate correctly.
Galvanized metal
Sofel has products to clean galvanized metal, to improve the adhesion of a paint layer or to strip the paint layer.
Powder coated metal
Powder coated surfaces such as garage doors, window and door profiles are very sensitive to colour and scratches and must be treated with the right products.
Sofel offers products to clean these surfaces, revive the colour and, if necessary, also to strip the paint layer.
