Do they have be handled differently than wood frames?

Yes.  See the above step-by-step tutorial for how to assemble them.  Plastic frames cannot be routed for assembly with a slot and peg system.  Rather, they are glued together.

Are they available in any size I want?

Yes.  We will cut them to whatever size you specify and send you the four pieces to glue together to make the frame.  We also carry the glue and band clamp you will need to complete the job.  1-800-246-4726

Do these frames look cheap and plasticky?

Not at all.  Hanging on the wall polystyrene frames are indistinguishable from wood frames.  For many people, the first time they know they are looking at a plastic frame is when they hold it in their hands.  Polystyrene frames are surprisingly light.

Are they strong enough?  

Yes.  Polystyrene frames are sturdy and will not bow under weight.  But don't drop them.  A hard blow can shatter pieces off of polystyrene frames.  Also, if you are framing in sizes greater than 22"x24", opt for acrylic instead of glass, to reduce weight strain at the joints.

Who stands to benefit most from polystyrene plastic frames?

Price conscious consumers and the framers who seek to serve them.  By reducing the price of a typical frame job, the use of polystyrene frames generates increased business volume. 

Will they crack when screwed into?

Plastic frames can take self-tapping (sheet metal) screws without cracking.

Will they melt when cut with a power saw?

No.  Melting should not be an issue if done correctly.  Use a 36-tooth blade in your saw and don't let the blade linger as you cut through the moulding.

Can they be cut with a manual miter saw?

Yes, because a manual miter saw generates very little heat when cutting.

Can they be sanded?

Yes, but only with a manual rotary sander.  Power sanders generate too much heat.

Are polystyrene plastic frames the same as acrylic frames?

No.  Acrylic frames are clear plastic desk top frames.  Polystyrene frames are traditional looking plastic picture frames, having the same look and appeal as wood frames, only much less expensive.

So why aren't polystyrene plastic frames more popular? 

Traditional storefront frame shops tend to steer clear of polystyrene frames as they reduce revenues by introducing a cheap frame alternative.  Also, polystyrenes don't work well in a production setting because of the increased handling required for gluing.

What advantages do they give me?

Plastic frames are less than half the price of wood frames and look exactly the same.  Yes, these frames are cheap, but if you are looking to satisfy a customer who is looking for a lower price but don't want to compromise on quality, introduce them to polystyrenes.  And because polystyrenes are so light, it's cheaper to ship them.
