Frequently Asked Questions
Q: Do iron gates and balustrading rust when used in exterior applications?
A: Yes - rust will appear normally within six months using ungalvanized iron. It will even bleed through powdercoat finish within this period. The solution is to always hot dip galvanize all iron work for exterior applications. This will usually provide at least 25 years of corrosion resistance.
Q: What is hot dip galvanizing?
A: Hot dip galvanizing is a process where finished irons products are dipped into a molten bath of 400℃ zinc. Adhesion is extremely high and permanent.
Q: Do aluminium gates and balustrading rust when used in exterior applications?
A: Yes - aluminium is prone to white rust. Marine grades should always be used for exterior applications but is still prone to white rust in the long term. Where any fixing point with stainless steel fasteners are used white rust will normally appear relatively fast - this is because aluminium and stainless steel react badly when used together.
Q: Are aluminium gates as strong as iron gates?
A: When comparing two products made from the same size materials and both made to the same quality, iron is much more robust and is much stronger than aluminium.
Q: What are the advantages of using aluminium?
A: Compared to steel, aluminium is very light weight.
