Inspired by nature. Designed for performance.

At Winsell, every color tells a story, one drawn from the world around us. With the National Parks Granite Collection, we set out to capture the untamed beauty and spirit of America’s most iconic landscapes. These five new granite resins aren’t just colors. They’re a reflection of the rugged terrain, the stillness, and the raw wonder found in the wild.
The Inspiration: Where Nature Meets Innovation
From the warmth of canyon walls to the cool hush of mountain shadows, each hue in this collection is shaped by the essence of the outdoors. We wanted to bring the freedom of the open landscape to rotationally molded products, the kind that live outside, work hard, and last for years.
Just like the National Parks themselves, this collection represents durability, character, and a quiet strength that never fades.
Engineered for the Real World
While the inspiration is natural, the science behind these granites is pure Winsell. Each formulation is built to perform, with superior coverage, processability, and consistency. Whether you’re molding playground equipment, outdoor furniture, or agricultural tanks, these resins help your products endure the elements and look their best longer.
Expect:
- Repeatable processing for dependable color in every batch
- High-quality, branded, prime material for strength and reliability
- Fewer streaks and swirls, smoother appearance
- Quick turnarounds and flexible color matching
We designed this series to make production easier and results more consistent because your products deserve a finish as strong as their purpose.
