Galvanising

Hot dip galvanised to last a lifetime!

Modern iron railing designs are constructed from hollow section steels rather than solid sections used in their traditional counterparts with greater consideration being given to durability and corrosion resistance.

They are maintenance free, longer lasting and aesthetically pleasing.

Hot Dip Galvanizing is a cost-effective simple process of corrosion protection consisting of dipping steel into a bath of molten zinc to produce a non-oxidising zinc-iron alloy layer on the surface.  It is probably the most economic, efficient and pollution-free process available to protect steel against corrosion.

The steel which has been cleaned of grease, paint and other contaminants, is immersed in the molten zinc which has been heated to around 450 degrees centigrade.

The zinc reacts with the surface of the steel to form a progressive and highly corrosion-resistant zinc-iron alloy coating.  This is metallurgical bonded layer that becomes an integral part of the steel making it extremely resistant to physical damage and rusting.

The layers can actually be harder than mild steel, which gives the total coating a very tough and durable finish.

The standard galvanize coating can have a typical maintenance free life of up to 50 years in rural areas and up to 25 year in urban/marine areas.

The process is completed under the European Standard BS EN ISO 1461.

PLEASE NOTE: that the very nature of hot dip galvanising can only be described as an industrial finish and can sometimes leave rough deposits on the bottom.
