Alpha Rail metalwork meet british standard BS EN ISO 146

BS EN ISO 146 provides a specification concerning the general properties of coatings used and the standards required for the treatment of iron and steel. These guidelines are produced by the British Standard Institute (BSI) and must be followed in order to protect structures made of these materials. These coatings, also called finishes, provide maximum protection against corrosion after they have been hot dip galvanised.

Structures that often need this treatment include fencing such as bow top, chevron and flat top fences. As well as providing protection, these coatings can improve surface properties of the structure such as adhesion, wet ability, scratch resistance and wear resistance. Aesthetically these coatings can also improve the appearance of the structure using colour or texture.
