Anybody know where I can purchase good quality stainless steel tables and shelving here in Chiang Mai?  I would like to inspect prior to buying, so on-line is not an option

Let's shift this to the CM forum for local knowledge.

DoHome out on HWY11 south stock Sanki plus others.

Seems how slow it is there, maybe some for sale at shops soon going belly up-closing..priced to move!

My step son has done a lot of business with a good restaurant supply business.  But, they only speak Thai.  I don't yet live in Chiang Mai so I don't know where it is.  I'll send OP a PM with name and number.

 

Hello,

 

There is a shop for professional kitchen here. Didn't go inside so don't know what they sell but seems quite big from the outside.

 

Cheers
