In Reply to: How to protect interior surface of steel tubing from corrosion posted by Mike Agius on February 08, 2004 at 10:29:11:
: I am in the process of thermal arc spraying pure zinc on top of iron railing constructed mainly of solid round and flat bar stock. However the handrail is made of 50mm diameter mild steel tubing, the interior part inaccesible to this process. The sprayed surfaces are then sealed and topcoated in an epoxy/polyurethane process. The finished product is to be installed 100m from the sea. Is it better to inroduce ventilaion in the hollow tubing or is it better to seal it completely ?
Hi Mike
Sealing it completely I think will be the best option.
