Galvanising: advising on how to:
Build up the layer-thickness of existing hot dip galvanising on any structure, whether old or new.
Repair damaged hot dip galvanising, whether it is new, old or badly weathered.
Galvanise mild steel modifications made to existing galvanised steelwork
Paint over galvanising with a coating system to give a duplex or triplex finish
Seminars and training on the following:
Galvanising cast-iron or cast-steel, brass, aluminium 5000 and 6000 series
Using galvanising to protect bimetallic welds or couples in atmospheric or immersion locations
Galvanising of thin-section steelwork, including automotive shells
We carry out inspections to assess the thickness of hot-dip galvanising zinc layers.
Where damaged or deeply scratched, to see if any area of the zinc has gone back to bare steel
Check sherardised bolts for pinholing or breaks in the zinc layer
Ensure that zinc plating has the minimum required thickness of zinc
