There are many specialty companies that do metals and specifically gutters.  They carry 4, 5 and 6 inch width gutters.  In the example shown here, 6" gutters are used, which is normally the recommended width.  The normal galvanized gutters run about 180 Baht per linear meter (installed), the gutter and downspout counting separately.  When you move up to stainless, which is rust proof, the cost goes up to about 400 per linear meter.  The galvanized is slow to rust, in has a life span of probably 10 years or more. 

The company will come out and measure your roof.  They then bring all the materials and assemble the gutters on-site.  They basically weld different sections together to make the required length.  Then brackets are set and the gutter is laid in appropriately.  The gutters are sloped at about 2% to allow the water to run down and out the downspout. 

Gutters are often used in combination with water tanks to capture and store rain water.
