Product Description

+
Owens Corning® Structural Composite Posts are engineered for superior strength and long-term performance in exterior, load-bearing applications. Designed to replace traditional pressure-treated wood posts, these structural members provide exceptional durability, dimensional stability, and resistance to moisture-related failure. Featuring an advanced web-structured composite core, Owens Corning structural posts deliver high strength-to-weight performance while maintaining consistent, predictable dimensions. This internal web design enhances load distribution, reduces material waste, and eliminates the internal defects commonly found in wood posts, such as knots, splits, and voids. Available in 4x and 6x sizes with 8', 10', 12', and 16' lengths, Owens Corning structural posts support a wide range of deck, porch, pergola, and elevated structure designs. Unlike wood, these posts will not rot, warp, crack, or twist over time—even in ground-contact or high-moisture environments. The result is a safer, longer-lasting structure with reduced maintenance and fewer long-term concerns. Owens Corning structural posts are compatible with standard post bases, connectors, and fastening systems, making them easy to integrate into both new construction and replacement projects. For builders and homeowners seeking dependable structural performance without the drawbacks of traditional lumber, Owens Corning offers a proven, high-performance solution.

For Small Boxed Items:

We offer a 1-2 day turnaround for small boxed items and a tracking number will be provided to keep you updated on the status of your delivery.

For LTL Freight (Common Carrier) Items:

We use LTL freight for safe and efficient delivery. Your order will be scheduled for delivery, and it's important to note that for decking deliveries, a homeowner needs to be on hand to unload the product. This ensures a smooth and hassle-free delivery process. Rest assured, we're here to make the process as convenient as possible for you.

    Once our team has meticulously packed your order onto a pallet for safe shipment, we're on the move. You can expect an email notification as your order leaves our facility, keeping you in the loop right from the start.

    At the agreed-upon time, the delivery truck will arrive at your specified location. You’ll inspect your order at the delivery site as it’s unloaded from the truck. You have a few options when it comes to semi truck delivery, which are hand unload (the standard delivery), liftgate, and flatbed/forklift. If you’re looking for something other than hand unload, please let us know at the time you schedule your delivery.

  4. Inspect and Unload Your Shipment:
