Galvanised and Painted Black | The metalwork is galvanised by being dipped in a basin of hot zinc, then prepared with a mordant T-wash solution, then primed and sprayed with one coat of black paint in our factory. Galvanising does not always produce a smooth surface due to the hot dip galvanising process. Reasonable fettling is included as part of the prep work. Small vent holes will be visible on hollow section steel.
Galvanising will generally stop the metalwork from rusting, unless the galvanising has chipped to expose the metalwork underneath. Site alterations can be made good by cold galvanising spray. It is advisable to to maintain the black painted finish from time to time.
