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.
The Waterproof, Low Maintenance Alternative to Natural Light-Grain Timber
TimberLine™ Maple HDPE captures the soft, inviting aesthetic of natural light hardwoods without the susceptibility to moisture, swelling, or rot. This easy-to-sanitize material provides a warm finish for outdoor kitchens and RV interiors that blends seamlessly into modern and traditional environments.
Unlike real maple wood, TimberLine™ will not rot, delaminate, or splinter. It is UV-stabilized to prevent the "fading" or dingy appearance typical of light-colored lumber. Whether you're fabricating outdoor seating or cabinetry, this material provides a long-lasting, "worry-free" finish.
Why Choose TimberLine™ Woodgrain HDPE?
This material is ideal for high-exposure outdoor living spaces. Choose TimberLine™ for:
Authentic Woodgrain Texture: A deep, embossed finish that provides a soft, natural wood look and tactile feel, ideal for cabinetry.
Superior Weatherability: Impervious to moisture, salt spray, and extreme temperatures. It will never require sanding, staining, or oiling.
Standard Tool Compatibility: Can be machined, routed, and drilled using standard carbide-tipped woodworking tools.
Enhanced Versatility: Unlike natural lumber, TimberLine™ can be heat-welded or thermoformed (heated and shaped) for custom curved projects and unique architectural elements.
Sustainable Design: Manufactured with sustainability in mind, this long-lasting material is 100% recyclable and reduces the demand for exotic hardwoods.
Common Applications
TimberLine™ is an excellent choice for environments where wood aesthetics are desired but durability is mandatory:
While HDPE is easy to machine, it is important to account for thermal expansion and contraction (roughly 1/32" per foot for every 40°F change). Like all HDPE products, TimberLine™ cannot be glued with standard adhesives. For structural assembly, we recommend mechanical fasteners or plastic welding.
When you order from Interstate Plastics, you're accessing an expansive nationwide network of material expertise. We source our TimberLine™ HDPE sheets from trusted manufacturers with strict quality standards, ensuring that your cabinetry or outdoor space project is ready for precision machining the moment it arrives.
Handling: Cut sheets may have sharp edges. We recommend wearing protective gloves when unpacking and handling this material to ensure safety.
Suitability: We take pride in the quality of our materials as they leave our facility. However, because every project is unique, we cannot account for how materials are modified, stored, or used after delivery. Please perform the necessary tests to ensure this material is right for your specific application and end-use conditions.

Technical Performance
TimberLine™ Maple is a specialized Woodgrain HDPE sheet engineered for aesthetic applications where the performance of High-Density Polyethylene is required. Engineered for maximum durability, TimberLine™ is a full-density, solid-core HDPE sheet.
Unlike lightweight foamed alternatives, this solid construction provides superior screw-holding strength and impact resistance, ensuring your cabinetry and marine fixtures remain structurally sound for a lifetime.
All-Weather Durability: TimberLine™ is completely hydrophobic with near-zero water absorption. It will not rot, swell, or delaminate even in high-moisture marine environments or direct rain.
UV & Color Stability: Formulated with UV-stabilizers, TimberLine™ Maple is designed to maintain its creamy-tan color over time without the "silvering" or bleaching seen in natural light hardwoods.
Authentic Texture & Variegation: Features a deep embossed woodgrain that provides a tactile, high-end feel. Unique streaking and color variations are integrated into every sheet, ensuring no two panels look identical.
Regulatory Compliance & Specifications
CPSIA, RoHS & REACH Compliant: Free from lead, phthalates, heavy metals, and hazardous substances. TimberLine™ is certified safe for use in high-touch environments, including playgrounds, public spaces, and residential outdoor kitchens.
Validated Material Properties: Tested according to ASTM standards for polyethylene plastics, ensuring a consistent density (approx. 0.96 g/cm3) and high flexural strength for structural cabinetry and outdoor furniture.
Key Properties
Maintenance-Free: Never requires sanding, staining, or oiling. Cleaning only requires soap and water or a pressure washer for stubborn debris.
Ease of Fabrication: TimberLine™ can be machined using standard carbide-tipped woodworking tools. Its solid-density profile offers superior screw retention and can be heat-welded for seamless joints.
Thermoforming: Unlike many other textured plastics, TimberLine™ can be heated and vacuum-formed or bent, allowing for custom curved architectural elements or boat trim.
Chemical Resistance: Resistant to salt spray, most household cleaners, and environmental pollutants, making it ideal for coastal and urban environments.
RV & Transportation: Vibration-resistant interior cabinetry and warm Maple-grain trim for automobiles and recreational vehicles.
Hospitality & Commercial: Resort cabinetry, poolside dining furniture, and common area storage requiring a bright wood aesthetic.
Marine Construction: Yacht cabinetry and trim where a warmer, light-colored woodgrain aesthetic is desired.
Landscape & Architecture: Decorative park fencing and sign backings that offer a natural, light-wood look.
Engineering Limitations & Alternatives
While TimberLine™ Maple is a superior outdoor material, certain projects may benefit from specialized alternatives:
High-Traffic Walking Surfaces: While TimberLine™ has a textured grain, it is not primarily designed as a non-skid floor decking for wet boat decks. Better Alternative: For high-traction walking surfaces, consider King StarBoard® AS (Anti-Skid).
Structural Spanning: As an HDPE-based material, TimberLine™ may deflect over long horizontal spans under high heat load. Better Alternative: Ensure adequate support every 16"–24" or use mechanical stiffeners for long benches and shelving.
Adhesive Requirements: Like all HDPE, TimberLine™ has a low surface energy. Standard wood glues and epoxies will not bond to it. Better Alternative: Use mechanical fasteners (stainless steel screws) or Plastic Welding. For specialized bonding, use 3M™ Scotch-Weld™ DP8005.
Industrial Wear & Friction: This is a cosmetic and structural sheet; it is not intended for high-speed conveyor wear strips. Better Alternative: For sliding abrasion or industrial guides, choose UHMW Sheet.
