One Supplier for All Your Decking, Railing, and Building Materials
Let’s be honest: coordinating with five different suppliers just to get one deck built slows your job down. Evolution Supply streamlines your workflow by offering a full catalog of building materials— from decking, railings, and Pergolas to exterior finish materials—all in one place.
Our approach is built around simplifying the construction process. When construction schedules are tight and project scopes are growing, you don’t have time to manage multiple shipments, handle backorders, or chase customer service. That’s where our team steps in. We stock in our warehouse:
- Decking and railing systems from industry-leading brands
- Pergola kits designed for fast install and lasting strength
- Interior and exterior millwork to finish projects strong
Coordinating with multiple vendors can slow your project down and drive up costs. At Evolution Supply, we offer a smarter solution. From your first set of plans to your final delivery, we’re here with everything you need in one place. Our team is deeply involved in each step, ensuring that your project is handled with care, attention to detail, and the level of precision you’d expect from a dedicated building partner.
Durable Decking Materials for Every Climate and Client
Today’s clients want outdoor living spaces that last, with minimal upkeep and maximum visual impact. That means your decking materials need to look great and perform even better. At Evolution Supply, we offer a wide variety of decking options to suit every project scope and design preference.
We proudly carry:
- Trex: One of the most trusted names in composite decking, Trex offers high-performance boards in a variety of colors, grain patterns, and sizes. Their low-maintenance surfaces and fade-resistant finishes make them ideal for everything from small patios to expansive wraparound decks.
- TimberTech: Known for innovation, TimberTech combines durability with modern style. Their capped composite and polymer boards offer top-tier moisture resistance and scratch protection, while still being easy to install.
- Traditional Wood: For clients who want a more natural aesthetic, we offer premium treated lumber options that provide flexibility in design and classic appeal.
Composite decking is a smart choice for builders who want long-lasting performance, low maintenance, and a clean, modern look. At Evolution Supply, we recommend composite options like Trex for their durability, resistance to moisture and rot, and minimal upkeep compared to traditional wood. One of the most common concerns with composite decking is heat retention—but Trex has stepped up with an innovative solution. Their new heat mitigating technology is designed to reduce the heat felt on the surface, making decks more comfortable underfoot even on the hottest summer days. With a wide range of colors, grain patterns, and profiles available, Trex composite decking delivers both performance and comfort—ideal for everything from cozy patios to expansive multi-unit projects.
Whether you’re dealing with lakefront humidity, suburban sun exposure, or heavily used community spaces, we’ll help you find the ideal material solution for each deck you build.
Railing Systems That Combine Safety, Style, and Compliance
Safety, code compliance, and curb appeal—railings need to deliver on all fronts. We carry a full selection of railing systems that are not only visually appealing but also engineered to meet or exceed local building codes. Whether you’re building for a single residence, duplex, or multi-family unit, we’ve got systems that meet your needs.
At Evolution Supply, we stock:
- Trex’s wide range of aluminum, steel and composite railings
- Westbury Aluminum Railings – Sleek, strong, and rust-resistant, these systems are ideal for both residential and light commercial applications.
- RDI Railing Systems – Offering a broad range of styles and materials, RDI is known for combining durability with ease of installation.
- ADA-Compliant Railings – Accessibility isn’t optional—it’s essential. We offer options that meet ADA standards to ensure safety and usability for all.
These systems are built to last and designed to enhance the look of any deck, porch, or exterior living space, whether residential or multi-family.
With multiple finish options, low-maintenance materials, and simple installation hardware, our railing systems help you meet code and please your clients—all while staying on schedule.
Pergolas That Enhance Decking and Outdoor Builds
Looking to enhance an outdoor build with a structure that combines function and style? Pergolas are the perfect solution. At Evolution Supply, we offer high-quality pergola kits that can transform an open space into a usable, shaded retreat—ideal for backyards, rooftop lounges, community patios, and more.
Our pergolas are:
- Engineered to withstand wind, rain, and seasonal shifts
- Available in multiple sizes, styles, and finish options
- Compatible with both wood and composite decking systems
Our pergolas are built to withstand the elements while enhancing the look and functionality of any residential or multi-home project.
