Decking Materials Designed for Colorado Jobsites

Colorado’s elevation, UV exposure, temperature swings, and snow loads demand materials that last. We stock products we trust because they are tested in real Front Range conditions.

Composite Decking

Composite decking is one of the most requested options among homeowners, and Mile High Deck Supply makes it easy for contractors to deliver consistent, long-lasting results. We carry high-quality composite decking engineered to perform in Colorado’s intense sun, snow, and wide temperature swings while maintaining its appearance over time.

Our selection includes trusted brands like Trex®, TimberTech®, and Dekorators®, giving contractors flexibility to match different design styles, performance needs, and budgets. These composite decking options offer realistic wood-look finishes, a wide range of color choices, and strong manufacturer-backed warranties. The result is a low-maintenance decking solution that helps contractors build with confidence and minimize callbacks.

Wood Decking

For projects that call for a traditional or natural look, we offer quality wood decking options suited for Colorado’s climate. Wood remains a strong choice for custom homes, mountain properties, and homeowners who prefer the warmth and character of natural materials.

Our team helps contractors select the right wood decking based on project goals, exposure, and budget, ensuring compatibility with railing systems and accessories for a clean, professional finish.

Railing Systems & Deck Accessories

A well-designed railing system enhances both safety and aesthetics. Mile High Deck Supply provides aluminum, steel, and composite railing systems that meet code requirements while complementing modern and classic deck designs.

We also carry deck accessories that add value and functionality, including privacy screens and integrated deck lighting. These options allow contractors to elevate outdoor spaces while creating opportunities for higher-value builds.

Patio Covers & Pergola Kits

Patio covers and pergolas are in high demand as homeowners look to extend the usability of their outdoor spaces. Mile High Deck Supply offers pergola kits and patio cover systems that pair seamlessly with composite and wood decking projects.

These systems provide shade, structure, and visual appeal while remaining practical for Colorado weather conditions. Whether included in a full outdoor living build or added to an existing deck, pergolas and patio covers help contractors deliver complete, high-end solutions.
