Stainless Steel gutters

[CallumWK]

I'm in the market for new gutters, and since I have about 100 meter of gutters, price is a factor.

The cheapest galvanized i can find is 360 baht, and add 50 baht if I want them to be painted.

Then I found a supplier with SS 304 for 600 baht a meter. I know SS can't be painted, but they are better quality of course

Previously I always heard prices of SS at 1000 baht up, so these seem very cheap, also compared to the galvanized ones.

They come in 6 meter lengths directly from the factory, and am told there is Thai quality and Chinese quality, with the latter one being of lower quality.

 

So what do I have to look out for, so I don't get fooled?
