Coatings are the simple and effective method to improve the life of metal by protection from corrosion. Basically coatings can be categorized based on the nature they serve the purpose-sacrificial coating and barrier coating.
Sacrificial coating are the one which corrodes preferentially to steel. Usually zinc base is used as sacrificial coating. Barrier coatings are the one used to form a layer between the substrate and external atmosphere or media so that no corrosion can attack the surface of metal.
We, SEF ,has concentrated on selecting suitable coatings for our own manufactured products and also free issue materials considering the specification International standards and the conditions where the materials will be getting used. Coatings plays the vital role in protection of components or materials used in application. Selection of coating is that so much important and another important factor is the application in proper way. We ensure that all the coatings are applied properly to serve the purpose by regular monitoring and stringent quality control procedures of SEF. We follow ASTM, BS, NACE,SSPC standards and also coating manufacturer recommendations for the proper evaluation of coating on each stage of inspection.
Specially designed machines and experienced coating operators has strengthen our capacity in the field of coating .Fastener products are having a wide range of coatings based on the scope of application and area of use which varies in quality and performance from a very low range to very special premium level.Additional to corrosion protection, anti -galling is also a special function offering for threaded items with our special coatings.
We can support our customers in selection of coatings based on suitability of their application. For details you can contact our sales/service desk.
