PVC or Melamine

[Step Johns]

So my question is does melamine warp when you have the lids on the tubs? Or is it just when you go "topless"?

Hi,

Since the point of malamine is the plastic covering and it is humidity that causes most warping you should never see it anyway.

As long as you seal any exposed cut edges it shouldn't be exposed to enough humidity to cause problems.

It may sag however if you are using it over too long a span.

Just make sure you get thick enough PVC. I bought one rack made from 1/4" PVC, and the levels bow really badly once there's any weight in the tubs. Not too pleased with that one at all compared to the melamine ones I built.
