It depends upon the quality of sliding fitting, the better the quality the more expensive the fitting. But better quality hardware is suggestive as its a sliding door. In normal doors you've to use good hinges but its not so expensive comparatively.

That explains his opinion. Your description until now was for outlay doors. Slideline 16 is capable for 50-60 kg and 18-24 mm doors only. As I said earlier, not a big fan of bottom running sliding systems. Hope it works fine for you. Steel decorative strip is possible . But avoid deep cuts on the door that would increase the chances of bend/warp.

hi. you can check with any local modular vendor. they will have a show room that you can visit so that you can understand the finish and textures etc. The sliding wardrobes with Hettich fittings will not spoil fast. a modular wardrobe starts from 900 per sq ft. customized design with proper fittings usually cost 1750 to 2000 per sq. ft if you get it carpenters, the cost will be more or less the same and the finish will not be as good or clean. but the design patterns are much more. modular has limits to the troupes of designs you can have

Ruchi, Sorry to hear about your problem. It usually happens when a wrong type of sliding mechanism or base material is used. You can try your luck with Door stiffeners or straighteners from EBCO, Hettich or Hafelle. Thanks, Nitin Cornerstone Designs, Bangalore.
