Must we drill holes for galvanizing? Alternative to galvanizing?

June 9, 2012

Q. I have question for you on galvanizing.

I have square tube, round tube, and angles of sizes varying from length 60 mm to 3000 mm. I want to galvanize these items (the total quantity is around 5000 pieces).

The problem is that my vendor is asking to drill holes for each piece, which is not feasible due to large quantity and shortness of time. So please, if any body could suggest any alternate solution for the same result we get by doing galvanizing?

A. If these are straight open ended tubes then there are other ways than drilling holes!

Holes are for two purposes: to vent/ drain the inside of hollow sections where they would otherwise be sealed.
And to suspend the item.

The 2nd reason can be achieved in a variety of ways.

We process lengths of tubing about 500 mm long and about 30 mm dia by the hundreds for one customer, and no holes drilled. They are straight lengths, open both ends.

Try another galvanizer!

A. Dear Friend,
Vent holes are a must in hollow sections for Galvanizing. As well as in solid fabrications any such area where the blockage of Zinc is possible, again holes are required.
