You can try Houz Depot or any of those shops that sells bathroom fittings.

spending 1k++ for a clothes hanger... crazy ...

U mean this one cost abt 1k?

Frankly don't think the ceiling hanging one will cost 1k. You can check them out at those shops selling bathroom fittings, Houz Depot, etc.
The most will be less the RM 300. These are all stainless steel rails. The price will depends on the nos. of rails.

The ceiling mounted type is quite convenient if you are placing them in the balcony as compared to those conventional floor type. As balcony space is quite tight, once you place the floor clothes hanger, no more space to move around. There are also the wall mounted ones. The type to use will depend on your space in the balcony.

I think if you are getting the floor type and non stainless steel (those with plastic coating type) will cost abt RM 100 only
