Where in BKK can I buy aluminium angle profile, 15 x 15 or 20 x 20?

Maybe we should try this in the Bangkok Forum. Topic Moved.

If you walk from Hua Lampong train station toward the River City Shopping Center (Chinatown area), you'll pass dozens of metal vendors scattered around just about every block. Most have steel, but a lot also have copper, brass and aluminum profiles in a wide variety of shapes and sizes.

Good luck!

Thanks a lot, Impulse!!

I'll give it a trial.
