How much do 4 x 8 sheets of 1/2" cast acrylic sheets cost?

[Oughtsix]

Someone local to me has six 4 x 8 acrylic sheets for sale at $1000. Does anyone know how much a sheet of 1/2" x 4' x 8' cast acrylic cost? Has anyone bought any lately?

It looks like one of the sheets has quite a bow in it... I suspect it would be trouble if it were used for building a tank???



They also do not appear to have the protective plastic wrap on them which would make them much tougher to cut without scratching. Being only 1/2" I believe a tank built with them should be kept to 24" tall or less.

I dont think acrylics are suppose to be bent, they're suposse to be flat, i think

Acrylic is notorious for its lack of dimensional stability. Even the thickest piece will warp for no real reason. You should be able to straighten it. but if not it's only a nuisance during assembly.

I suspect Lepisosteus might know.

Seems like a good deal, but I don't think 1/2" is thick enough to build a monster tank, unless you're planning to build multiple smaller tanks with it.

Thank you for all the information!!!

I am thinking of building a 24" tall x 30" wide x 6' long tank. 5 sheets would be plenty, I wanted to know if I should consider the sixth piece useless... which it sounds like I can make use of it. 1/2" cast acrylic is well within spec for a 24" tall tank. Height is the major determining factor for acrylic thickness. I considred a 30" x 30" x 6' tank which should also be fine with 1/2" but will have more bowing than 5/8" or 3/4" acrylic would.

This is a lumber yard so I think I will offer them $700, leveraging the warped piece and see if I can pick it up for $800. Usually businesses are a little more flexible on clearance prices than an individual.

Why does a lumber yard have pieces of acrylic for sale?

Just use the bent piece to make a bowfront right?
Serve the lemons life offers you!

I have not contacted them yet but I am guessing it was a special order for a customer that backed out on them. They posted their whole sale invoice for $1645 back in 2016 so they have been sitting on them for about 3 years now.

I plan on contacting them on Monday.
