Product Overview

Nobody’s perfect, and neither is this factory-second slate gray composite decking. Boards have varying cosmetic defects – there might be color variations, scratches or minor bends. Once bent boards are installed, the bend isn’t noticeable.

Slate Gray capped composite boards are embossed with a wood grain pattern and have realistic color highlights, so they look like wood, but behave better - no sealing required. The extruded composite material has low expansion-contraction rates and resists water absorption.

Installation: The boards are slotted, so you install them with hidden fasteners. These fasteners automatically space the boards at ¼ inch, allowing for natural expansion and contraction. NOTE: We don't recommend using slotted boards where edges will be visible.

Available with slotted edges.

Choose slotted-edge boards when you want a fastener-free surface (we recommend these Hidden Fasteners).

Deck boards, fascia, and hidden fasteners are for local pickup only in Norton Shores, Michigan. If your order has items in addition to these products, we’ll ship them to the address specified at checkout.

We process orders on business days. Please allow at least 24 hours to process. After processing your order, we’ll contact you with pickup details. Because of processing time, same-day pickup is not available.

Loading assistance and forklifts not available. Bring a buddy to help you hand-load boards onto your trailer. You’ll need to load and properly secure your product - a heavy-duty strap is strongly recommended.

We recommend a heavy-duty trailer and tow vehicle capable of handling product length and weight. Composite boards are 16 feet long and weigh about 40 pounds. The boards are flexible - to prevent damage during transport, do not allow more than 2 feet to hang over the end of the trailer without support.
