ZINC PLATED STEEL
A low carbon steel for general use. Zinc plating provides a moderate corrosion resistance suitable for indoors or otherwise dryconditions. Colour is either a blue-ish tint or yellow depending on the exact process utilised during manufacture.
Hot dipped galvanised steel has a very heavy coating of zinc for better corrosion resistance, making it suitable for outdoor use. Because of the thick plating, only galvanised nuts and washers will fit galvanised fasteners. The coating typically has a rough, dull grey finish.
Stainless steel offers good corrosion resistance in many environments and is suitable for outdoor use.
304 stainless steel composition is 18% chromium and 8% nickel and is suitable for outdoor use.
304 stainless steel is not recommended for use in water.
316 stainless steel has increased corrosion resistance due to the addition of 2% to 3% molybdenum. It is suitable for marine, chemical, petrochemical, manufacturing and transport use.
When working with 304 and 316 stainless steels, it is recommended that stainless steel tools are used. This avoids cross contamination of the stainless steel by easily corroded metals that may discolour the surface of the 304 and 316 stainless steel product.
