As per our Shipping and Returns Policy, custom cuts and fabricated parts are non-returnable. If you need an over- or undersized item, note it under "Comments" during Checkout. Cut-to-size orders have an acceptable cut tolerance of 1/8" (0.125"), so clarify if the adjustment is to be made on the (+) or (-) side of the saw blade.Please review our full return and shipping policy here.
Measure Twice, Cut Once
Since custom cuts and fabricated parts are non-refundable, be very careful while measuring your dimensions. As each cut is nominal, even the slightest miscalculation could be costly.
How to Use a Measuring Tape
Extend your tape measure several inches to find the 1 and 2 inch markers. In between the inch markers you’ll find 16 equally spaced tick marks.
Measure by counting the increments beyond the nearest inch. As the increments decrease, so does the length of the mark. For example, 1/2" has a bigger mark than 1/4" which has a bigger mark than 1/8". The smallest mark follows at 1/16". Please be aware that some measuring tapes may have even smaller increments.
Features of a Measuring Tape: Sliding End Hook
The sliding end hook is designed for two different types of measurements. An outside measurement (where the hook of the tape hangs over an edge), requires the hook to slide out a bit to account for the thickness of the material. When making an inside measurement (where the hook will push up against a surface), the clip slides in, again, accounting for its thickness. The measuring tape self-adjusts to guarantee an accurate measurement (as far as the tape is concerned).
Sanitizing Acrylic and Polycarbonate Sheet [X]
Acrylic and Polycarbonate Sneeze Guards and like products require special care while cleaning and disinfecting. To maintain the optical clarity of sneeze guards and other acrylic or polycarbonate items, use an acrylic or polycarbonate safe cleaner like Novus Plastic Polish #1, Brillianize Plastic Cleaner, or a mild soap solution.
Please reference the following compatible cleaners when DISINFECTING acrylic and polycarbonate items. The use of commonly available commercial alcohol or ammonia-based disinfectants may cause crazing and damage.
Clear Acrylic extruded sheets are an economical alternative to polycarbonate (PC) when extreme strength is not necessary. It is often preferred because of its moderate properties, easy handling and processing, and low cost, but behaves in a brittle manner when loaded, especially under an impact force. Transmits up to 92% of visible light (3 mm thickness), and gives a reflection of about 4% from each of its surfaces on account of its refractive index. It has a density of 1.17-1.20 g/cm3, which is less than half that of glass. It also has good impact strength, higher than both glass and polystyrene.
Acrylics have outstanding resistance to long-term exposure to sunlight and weathering. Acrylic has excellent optical properties and is more resistant to impact than glass. In addition, acrylic has low water absorption, good electrical resistivity, and fair tensile strength. Applications are infinite, including art installations, outdoor signs, glazing, aircraft canopies, skylights, automotive taillights, dials, buttons, lighting applications, knobs, and machine covers.
Acrylic sheet is 17 times stronger than glass, has excellent clarity, durability, is lightweight and weatherable. Acrylic can be sawed, routed, drilled, formed, line bent, cemented and painted.

Cast Acrylic vs. Extruded Acrylic: Acrylic is produced in two basic variations, cast and extruded. Casting and extruding acrylic produce slightly different properties. Cast acrylic is more difficult to bend and shape versus extruded. In heat bending and thermoforming, extruded acrylic may behave differently depending on the bending direction relative to the extrusion direction. This is not an issue with cast acrylic. When colored cast acrylic is heated for thermoforming or heat bending, the color may change. Matte-colored surfaces can become clear and clear surfaces can become matte or opaque. In addition, the shade of color may change. Laser engraving should only be done on cast acrylic to produce a clear engraved image. In laser cutting, extruded acrylic will have a rougher edge, whereas cast is generally smooth. Cast is more difficult to flame polish versus extruded. Extruded acrylic tends to be more consistent in sheet thickness, while cast can vary as much as +/- 15% in thinner sizes. Cast acrylic is more resistant to the same solvents, as well more resistant to scratching versus extruded.
Acrylic applications are infinitely broad. Here are a few common examples:
Glass Substitute: aquariums, viewing ports for submersibles, automobile light lenses, hockey rink guards, riot protection, bullet-resistant glass applications (i.e. banks, gas stations, vehicles transporting valuables)
We Have received the order from your firm and I must say the pieces of plexiglass are terrific! Perfect fit ? the larger sheet was replacing a piece that was 32 yrs old on the top of a showcase ? looks great and certainly improved the looks of the showcase! Thank you!

My first order with them. I like the fact I can enter the exact size I want and pay just for that material. Came packaged well within a few days. I would definitely recommend this company.

came with a chip in it. Interstate offered to take the material back, but it wasnt worth the trouble. Somewhat high freight. Fair customer service.

Purchased 9 pieces. The product shipped a little slow, but they sent me 10 as I had essentially purchased 2 whole sheets. They were very helpful and the product was wonderful.

the first time I ordered from the website I got cast paper acrylic and taking off the sticky paper was a nightmare! I was recommended to order film instead and it made my life so much easier, it's same exact material just different protective covering. Thanks for the advice interstate

I needed this for a craft with my kids and this was the cheapest I could find. Excellent quality and it shipped so fast.

Just opened my order to find half of the sheets were broken! Emailed the perosn that helped me and they are sending me replacement material at no cost. Thanks for the help!
