Unlike other coatings which only cover the outer surface, hot dip galvanizing protects every part of the article – both inside and out. No other coating provides the same level of corrosion protection.
The hot dip galvanizing process creates zinc-iron alloy layers that are harder than the underlying steel. This gives galvanizing its great abrasion resistance that reduces the likelihood of damage during transport and installation – minimising the need for on-site repairs and maintenance.
