Options- Protective
Coatings and Finishes
 Steel as
a standard 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 hangar 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. However it is
harder to overpaint galvanised steel. Our standard primer is suitable for most
fire protection paints.
| Shot
Blasting All steel passes through our
Automatic Shot Blasting plant before fabrication. |

|
Protective Coatings All steel before leaving
our works is sprayed with High Build Zinc Phosphate primer, to a thickness
of at least 75 microns. Other coats applied in
house will add to cost and dispatch time, especially with the new low
solvent paints. Decorative final coats should be applied after erection by
you specialist. |

| Hot Dip
Galvanising Hot Dip Galvanising is the best
way of providing long term protection to structural steelwork. It is no more
expensive than complicated multi-coat paint systems and more effective. During the last 25 years there has been an increase in
demand from discerning clients, for the tough, lasting protection provided
when steel is dipped into molten zinc. If you want ONLY THE BEST then you
should have your steelwork HOT DIP GALVANISED. Please ask our advice for the
suitability of your steel. |
