Does anyone know if there is a website for Thai Watsadu in English, so far I have been unable to find it.

Failing that if anyone can read it and send me a link to roof tiles section ( with pictures ) i'd be very grateful.

Thanks.

They don't have.

Also: as far as I can see, there is no detailed product catalog online.

Only general listing of product categories and some promotions.

E.g. this would be the entry to structural/steel/roof/cement/pipes:

http://www.thaiwatsadu.com/cat-a.html

But the links lead to nowhere (just bookmarks).

I would be happy to be proofed wrong.

I repeatedly tried to find detailed product lists/catalog online for one of the major home store without success,

Right, no catalog, just a paragraph summarizing the different types of roofing products they sell.

AFAIK, The only home improvements chain store that has a detailed catalog online is HomePro, but under their internet-only sub-brand: http://www.directtoshop.com/

Prices are the same as in-store, and you can also check whether your closest shop has the items you want in-stock.

Interesting link

But another answer to the question: "how do they make money" (from another thread).

E.g. this filter housing, down from 1090 to 890 Baht:

http://www.directtoshop.com/webapp/wcs/stores/servlet/en/directtoshop/kitchen/water-purifiers/water-purifier/filtex-iv-408-water-purifier-p234952

Its nothing but a transparent PVC housing for waterfilters.
