Options – Protective Coatings and Finishes
All steel passes through our Automatic Shot Blasting plant before fabrication.Our steel is shot blasted (SA2) 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.
