Things You Need to Know About Working with HDPE Sheets.
The most used plastic sheeting internationally, High-density polyethylene (HDPE sheets) is a pretty remarkable resource. It’s used to make almost anything from walls/construction to toys.
Before starting, here are things you need to know about working with HDPE.
Fastening & cutting
- HDPE sheets, such as 4×8 HDPE sheets, need to be fastened with a screw, plastic rivet, or nail. HDPE is strong, but luckily it’s nothing a good power drill and a steady hand can’t overcome.
- HDPE sheets can be cut or drilled the same way you would wood.
- HDPE sheets cannot be glued to itself or other materials as there are expansion and contraction of the material as it adjusts to temperature and its environment. If you use glue on HDPE sheets, it will break away from the plastic and not stick.
Can you paint HDPE sheets?
- For the same reason listed above, HDPE sheets cannot be painted.
- We will color match the sheets, you just provide the color swatch. The minimum per color is 3K lbs.
HDPE sheet attributes
- HDPE is also very slick and slippery so avoid walking on the material and do not use it as a traffic surface unless you’ve used the appropriate safety measures.
- You can use HDPE for many quirky uses so get creative. You can even write your ideas and project plans on your HDPE sheets like a dry erase board.
- Extreme temperatures will not make HDPE crack or break
- HDPE is famous for being very rigid, but it’s not brittle. It won’t break when bent with two hands or the average tool – even if the Hulk were to give it a try.
- If we’re making HDPE sound too rigid for your project in mind, the thinner sizes are flexible and can be worked into whichever shape or size you require.
Sustainability
- HDPE comes in solid sheets of material. It’s 100% high-density polyethylene without any fillers.
- Thanks to the growing sustainability movement among most industries, the market for HDPE sheets continues to grow due to it being 100% recycled, thus doing our part to “complete the loop” with fewer materials needed.
- There is no set use for HDPE sheets. You can use it for bird boxes to concrete forms to skateboard ramps to hog pens; It is a very universal product.

December 8, 2020 - 8:21 pmLooking for 1″ thick black hdpe cutting board material.
Sandhill Office
December 11, 2020 - 8:57 amWe do no manufacture 1″ plastic sheeting- sorry!
The thickest is 5/8″ with a 25 sheet minimum.
Thanks
Sandhill Office
December 28, 2020 - 9:04 amSorry- we do not manufacture anything that thick. We do have 1/2″ material available that works nicely.

April 17, 2024 - 9:05 amHi I want to use this to make a fold down sailboat cockpit table. overall 30″x30″ but I will hinge 2 sides so I can fold it up. So my cuts will be 1 @ 15×30″ and 2@7.5×30.
Wondering if this warps and what thickness I should use. Was thinking 3/4″ or 1″. Lighter the better.
Thanks,
Julie

April 22, 2024 - 1:39 pmHi
You will need to make sure to allow room for expansion and contraction to happen, basically letting the plastic breathe. You will have to purchase an entire sheet and the thickest I manufacture is 1/2″
We can cut to size you need.

April 11, 2021 - 8:46 pmI want to install flexible/bendable milky-type sheet to tuck under the stovehood to act as protection from grease platter.What would you recommend when one needs under stovehood protection? What kind of very thin yet flexible/bendable plexi sheet would work and how many inches thin? I’d appreciated for all your help in this matter.
Sandhill Office
April 12, 2021 - 9:02 amWe sell 4′ x 8′ sheets. The thinnest I manufacture is 1/16″ thick in white or black.

May 5, 2021 - 2:40 pmIf I wanted to put HDPE sheet as a wainscoting panel in a barn would I need to have plywood behind it or can it just be mounted to the studs?
Sandhill Office
May 13, 2021 - 1:57 pmYou can do either. I would suggest if you mount to the studs, you go thicker. If you have plywood and just need to line it, you can use 1/8″

August 6, 2021 - 10:24 amWill this work as a skateboarding surface?
Sandhill Office
September 2, 2021 - 4:22 pmYes we have had a few parks do this across the nation with the plastic sheeting.
Jason
February 22, 2022 - 5:52 pmCould I stand on 1/2” sheet without it bowing in the middle? Looking for flooring that would be supported around the edges by a steel frame. (52”x70”).
Sandhill Office
February 25, 2022 - 11:06 amNo- it wouldn’t bow in the middle- sorry
Mike
August 12, 2021 - 4:12 pmI want to use a sheet of the HDPE on the nose cone of my sons Muskie boat. Will a good fiber Glass resin stick to the sheet. I’m Fiber glassing to both plastic on the top and wood at the bottom. I’m only going to cut the piece 10″ high. Would I also use a good plywood blade to cut this product. Thanks
Sandhill Office
September 2, 2021 - 4:22 pmThat will not stick to the hdpe, sorry.
Scott
August 3, 2022 - 8:52 amWould anti slip HDPE be good for a boat shower pan grate? 10”x19” span.
What thickness with some holes for drainage would not Bow or flex? 3/4” or 1”?
Sandhill Office
October 19, 2022 - 3:09 pmWe do not manufacture anti slip HDPE, sorry.

September 7, 2021 - 1:57 pmWhen hanging hdpe is there a right or wrong side to line a building to be powerwashed
Sandhill Office
September 8, 2021 - 11:31 amIt’s strictly your preference- one side is matte and one side is glossy. It will have no impact on right or wrong way.

November 29, 2021 - 8:47 amCan I use an HDPE sheet as a whiteboard to be used with markers?
Sandhill Office
December 8, 2021 - 12:03 pmI am sure you can. It may absorb a bit of the color but should wipe fairly clean
Mason Mullock
December 5, 2021 - 4:22 pmWhat thickness would be used for the top layer of a skateboard ramp? This would not be structural, just a nice surface on top of the structural layers of plywood. Also, what is the minimum order?
Thank you!
Sandhill Office
December 8, 2021 - 12:02 pm.090″ or 1/8″ would be perfect
Kris
May 28, 2022 - 6:35 amII am making my garage a hockey shooting area. I would like to put this on the walls of my garage to protect the walls from hockey pucks. What thickness of HDPE would you recommend?
Sandhill Office
June 15, 2022 - 1:14 pm1/2″ would be the best
Clarence
July 12, 2022 - 2:16 pmMaking a ski locker lid for my boat floor how thick do I need to support a 250lbs man 13inches wide by 37 inches long
Sandhill Office
July 12, 2022 - 3:36 pmWe sell 1/2″ but I am not sure that won’t bow with the 37″ not being supported underneath.
If you have support, there should be no worries.

July 27, 2022 - 2:48 pmI’m looking at HDPE as a possible plastic for a smaller tabletop on a new product I’m developing for exterior use .
I’m thinking 3/16″ thick would be ideal. The BIG question is – can this be thermoformed/pressure formed to add some simple, shallow, circular features?
Sandhill Office
October 19, 2022 - 3:10 pmYes it can be thermo formed
Ryan
August 3, 2022 - 1:19 pmI have an application that requires the use of 1.5″ square tubing functioning as joists underneath the HDPE. To support up to 300 pound static, centered load, what would you recommend for maximum spacing between joists if using 1/2″ HDPE? What about for 3/8″?
Sandhill Office
October 19, 2022 - 3:09 pmMaybe 16″ ???? I am not sure HDPE sheets are ok for this b/c they may end up sagging at some point if not properly supported.

August 27, 2022 - 2:58 pmI am restoring an antique automobile and need a flexible tack strip 3/8” by 1/2” by 72” long to tack the upholstery to.
Will the hdpe hold nails and staples for upholstery?
Sandhill Office
October 19, 2022 - 3:08 pmYes
Will Gilliam
September 25, 2022 - 6:11 amConsidering to use this for an agritourism farm slide, any idea if the matte side or the glossy side is slicker? Would assume that it would be glossy, but just to the touch it feels if matte might be slicker, – any thoughts would be appreciated. Thanks
Sandhill Office
October 19, 2022 - 2:57 pmEither side will work just fine 🙂
Ryan
October 11, 2022 - 7:59 pmHow can I add texture or raised traction spots to an HDPE sheet, so that it can be walked on safer without being so slippery, or drive equipment across it?
Sandhill Office
October 19, 2022 - 2:56 pmThe smooth plastic is always going to be slippery, I do however, sell a ground protection mat with a raised diamond pattern. Check it out on the website- it’s called access mat.

October 18, 2022 - 10:53 amIf I am building a house boat and want to use 4×8 sheets as walls, would HDPE be a good choice? I’d like to make the walls function as two-way mirrors, reflecting the exterior light.
Sandhill Office
October 19, 2022 - 2:55 pmI am not sure how your set up is. Are you screwing the plastic into studs? Are you wanting the plastic to act as a two way mirror?
Paul Ardesch
November 7, 2023 - 5:36 pmHello. You said it can’t be painted. What about the use of plastic primers? I am sure they use HDPE in car bumpers and the like.
Sandhill Office
April 22, 2024 - 1:43 pmThey quite possibly use HDPE in bumpers, but it is stress relieved so it won’t expand and contract. Those are paintable.
The HDPE we manufacture is not stress relieved and not able to be painted.
Julia Deffner
November 17, 2023 - 3:13 pmI want to bend an HDPE tube into a cylindrical shape (approximate diameter of 1.5 inches). I would like it to be as rigid as possible but still be able to bend it into this shape. Is this possible and what thickness do you recommend?
Sandhill Office
April 22, 2024 - 1:42 pmOur plastic is too rigid to be able to make a bend that small in diameter, sorry.
Tom
November 20, 2023 - 10:17 pmI would like to bend the sheet into a large diameter tube as a Christmas decoration and put led lights inside it. Would 1/16th be the proper thickness to allow the circular bend and would that thickness diffuse the light well?
Sandhill Office
April 22, 2024 - 1:41 pmThe plastic is not translucent, sorry. It is opaque.
John Ballew
January 6, 2024 - 9:34 pmI’m planning on making a faring for my ford transit roof rack. Rough dimensions are 75”x12”. What thickness would be best for this use?
Sandhill Office
April 22, 2024 - 1:40 pmWe manufacture 1/16″ up to 1/4″ that is bendable to make the faring. If you want something more rigid, go thicker. We manufacture up to 1/2″ thick.
Leroy
February 10, 2024 - 8:46 amI’m thinking about buying this product to put on a 5 1/2 x 12“ glue lamb. My beam is 70feet long if I make my joints tight will it expand and retract?
Sandhill Office
February 27, 2024 - 10:11 amYou are not able to glue this plastic, as there is expansion and contraction that will take place. Thank you for asking!
Ed Cichon
April 23, 2024 - 2:06 pmCan your 1/2″ sheets span 19″ and carry minimal (10lbs) of weight? I’m constructing a wall of shelves to hold pool towels at a country club.
Jason Chase
June 6, 2024 - 9:38 pmDo you have a gallery of some of the CNC jobs you’ve done? Just curious about what some of the possibilities might be. I have a few ideas.
Sandhill Office

July 16, 2024 - 4:08 pmIf I used an HDPE pad to thermally isolate a bolted and cantilevered steel beam canopy on the exterior of a building, any thoughts on the thickness of the pad between the interior steel and exterior steel?, 1/4″ or 1/2″?
