Outdoor environments require durable building materials that can hold up to constant exposure to sun, moisture, and changing weather conditions. Traditional materials like wood, metal, and standard plastics degrade over time—rust, delaminate, or rot.
King Plastic Corporation manufactures a wide range of polymer building sheets that are engineered for long-term outdoor use. With UV stabilization built into both the resin and the color, these sheet products are designed to maintain their integrity and appearance over time—even in some of the harshest conditions.
There are several reasons King Plastic polymer sheets are specified over wood, metal, and non-stabilized plastics for outdoor applications across a variety of industries, and we’ll start with three.
1. UV Stabilized for Long-Term Outdoor Performance
Nearly every polymer sheet manufactured by King Plastic is UV stabilized in both the resin and the color, helping the material resist fading, chalking, and surface degradation. This makes them suitable for environments with high sun exposure and temperature extremes.
Where it’s used:
- Marine: Products like King StarBoard® Family of Products are used in boat cabinetry, hatch covers, and non-skid decking where exposure to saltwater and sun is constant.
- Outdoor Kitchens: King DuraStyle®, King StarBoard® ST, and King StarBoard® WG products are used to build outdoor cabinetry, which is then exposed to a variety of weather conditions. The products offer a designer look with low maintenance compared to wood and metal.
- Healthcare: King MediGrade® adds advanced antimicrobial protection to the product while maintaining its appearance under frequent cleaning and exposure to UV light.
2. Will Not Rust, Delaminate, or Rot
Unlike wood or metal, King Plastic sheets are waterproof and will not rust, delaminate, or rot. This level of performance is consistent across marine-grade, architectural, and industrial market applications. The products retain an easy-to-clean finish and are ideal in high-contact environments.
Where it’s used:
- Parks & Recreation: King ColorBoard® and King ColorCore® are often specified for playgrounds, park signage, and wayfinding due to their moisture resistance and vibrant colors.
- Signage & Branding: King ColorCore® is frequently chosen over painted or laminated substrates for engraved signs due to its high-impact-resistant polymer to handle more abuse than conventional sign materials
- Industrial: King Hy-Pact® offers high impact strength and UV protection for both indoor and outdoor components and protective barriers.
3. Easy to Fabricate and Maintain
King Plastic sheets work like wood and can be fabricated using standard woodworking tools or CNC fabrication. They never require painting, sealing, or refinishing, and are designed to reduce long-term maintenance costs.
Where it’s used:
- Marine Applications: In boat manufacturing, fabricators rely on King Plastic products for components that must withstand continuous exposure to saltwater, sunlight, and moisture. King StarBoard® is used for structural and finish elements such as cabinetry, hatches, and doors. King StarBoard® AS offers a textured, anti-skid surface ideal for decking, ladders, and swim platforms. King StarBoard® XL provides a lightweight option for non-structural parts like cabin walls and interior panels. King StarLite® XL is an economical, lightweight sheet often used as a substrate for seating, storage units, and other utility applications where weight and cost are factors.
- Architectural Applications: King StarBoard® ST is often used for partitions, built-in cabinetry, and furniture in commercial or public spaces. Its enhanced stiffness and matte finish make it suitable for high-traffic environments that require structural reliability and a clean aesthetic. King StarBoard® WG features a wood grain finish that offers a look of wood without the maintenance. It’s commonly used for outdoor kitchens, furniture and decorative elements to combine the functionality of environmentally stabilized HDPE—without the upkeep of real wood.
- Outdoor Cabinet Doors: King DuraStyle® is a custom door program that combines King StarBoard® ST, the environmentally stabilized polymer building sheet, with designer styles and state-of-the-art CNC fabrication.
