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).

HDPE Sheet - Natural High Density Polyethylene
Natural Virgin Grade HDPE | Cut-to-Size & Full Sheet | FDA & USDA Compliant
The FDA Compliant Standard for Sanitary & Chemical Environments
Natural White HDPE is the standard for environments requiring superior chemical resistance. Manufactured from Virgin Grade resin, this lightweight, impact-resistant sheet is engineered for near-zero moisture absorption and stress-relieved for easy machining.
As a food-safe material, Natural White HDPE is the commercial standard for cutting boards, food processing chutes, and liquid storage tanks. It provides excellent chemical resistance to acids and cleaning agents, making it a low-maintenance choice for sanitary environments.
Note on Surface Finish: This is an unmasked, industrial-grade plastic. Minor scuffs are normal and do not affect performance. If you require a pristine, textured cosmetic finish (e.g., for visible boat cabinetry), we recommend King Starboard®
Why Choose Natural White HDPE?
This sheet is engineered for durability in demanding sanitary environments. It is the correct choice if your project requires:
FDA, USDA & 3A Dairy Compliance: A non-porous, virgin material that meets NSF/ANSI Standard 51 for food equipment. It resists mold, mildew, and bacterial buildup.
Broad Chemical Resistance: Impervious to most common chemicals, solvents, acids, and cleaning agents.
Easy Fabrication: Can be easily cut, routed, and drilled using common woodworking tools. Unlike many plastics, HDPE can be welded for seamless tank construction.
Rigidity & Stiffness: HDPE is a structural panel that is stiffer than UHMW, making it ideal for tanks and cabinetry.
Thermoforming: Unlike UHMW, HDPE can be heated and vacuum-formed. This makes it ideal for manufacturing complex 3D shapes like automotive dunnage, custom trays, and equipment housings.
HDPE vs. UHMW: Which Do You Need?
While both are durable polyethylene-based plastics, they excel in different environments.
Choose HDPE (This Sheet) for structural components, tanks, static panels, and cutting boards. It is stiffer, weldable, and more cost-effective.
Choose UHMW if you need extreme sliding abrasion resistance (e.g., conveyor guides, wear strips) or a lower coefficient of friction.
HDPE is non-abrasive and easy to machine using common woodworking tools. It can be cut with standard carbide-tipped saw blades and drilled with standard bits. Note that due to its chemical resistance, HDPE cannot be bonded with standard adhesives; it must be mechanically fastened or heat-welded.
