1. Galvanised: Galvanising steel or Zinc Galvanised steel as it is sometimes called refers to the process where steel is immersed into molten zinc. This is where a series of zinc-iron alloy forms a series layers via a metallurgical reaction between the iron and zinc, providing a robust coating which is an integral part of the steel.
Galvanised steel is among the most corrosion resistant due to its sacrificial protection and self-repairing properties. According to the Galvanizers Association they say “Hot dip galvanising offers coverage both externally and internally within hollow sections, it self-repairs when damaged, sacrifices itself to protect the base metal, is environmentally sustainable, has good impact and abrasion-resistance and a maintenance-free life of 50 years or more. Galvanised steel is widely used in applications where corrosion protection is needed and can be identified by the crystallised pattern on the surface (often called a ‘spangle’).” ↩
2. Steel: Is the “world’s most important engineering and construction material” according to the World Steel Accosiation. When it comes to garden structure steel is often a very strong and durable metal, although if it is untreated then it is prone to rust and corrosion. Steel is an alloy of iron mixed with less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen. When steel comes into contact with water and oxygen there is a chemical reaction and the steel begins to revert to its original form – iron oxide (that’s Rust to the layperson). Steel must be coated in a protective layer to stop this reaction, for most garden applications this consists of powder coating or the more stable and long lasting use of galvanising the steel first. ↩
