Options- Protective
Coatings and Finishes
Our steel is shot blasted SA2½ and is primed with 75 microns of high build zinc
phosphate primer. This is not intended to be used as a final finish. However
many clients, especially those who are paying with their own money, leave this
primer as the only finish. If rust shows through where the steel has been
scratched during transportation, erection or in use it may be touched up. If the
climate is known to be corrosive, for example, if the building is close to the sea on a windward coast, or is likely to be
subject to saline dust then we recommend hot dip galvanizing. This is much
better, cheaper and more enduring that any multi-coat paint specification. If it
is to be overpainted, etching primer must be used first.
