Saluda Springs CBU & Mail Kiosk Cover

Mitchell Metals supplied and installed a 12-box back-to-back CBU mail kiosk cover at Saluda Springs in Greenwood, South Carolina, for home builder Smith Douglas Homes. The structure uses 6×6 aluminum posts and beams finished in Dark Bronze, and was delivered as a turnkey package that included the cluster box units themselves.
A first project together, and a mail center built to last
Saluda Springs is a new single-family community taking shape on Siloam Church Road in Greenwood, South Carolina. As the streets and homesites came together, the development team needed a centralized mail area that would meet USPS and ADA requirements, stand up to South Carolina weather, and look like a deliberate part of the neighborhood rather than an afterthought bolted on at the end.
This was Mitchell Metals’ first CBU and mail kiosk cover installation with Smith Douglas Homes. We handled it the way we handle every residential mail center: one point of contact, one submittal package, and one crew responsible for the finished result — cluster box units and canopy together.
Why a covered mail center matters to a community
A cluster box unit sitting in the open is a maintenance item. Sun fades the finish, rain and ice reach the box faces, and residents get wet collecting their mail. A properly engineered canopy solves all three at once. It shades and shelters the units, it gives the mail area a defined sense of place within the neighborhood, and it becomes one of the amenities prospective buyers actually notice on a tour.
At Saluda Springs, the back-to-back configuration was the right call. It puts two banks of boxes under a single roof structure on one concrete pad, which keeps the footprint tight, keeps the pad and site work economical, and gives residents room to pull in and collect mail from either side without crowding.
Dark Bronze, 6×6 posts, and the details that hold up
The structure was finished in Dark Bronze with 6×6 posts and beams. The heavier post and beam profile does two things: it carries the load with confidence, and it visually anchors the structure so the canopy reads as permanent architecture instead of a lightweight shelter. Dark Bronze is the finish most residential developments choose because it recedes against landscaping and reads as a neutral in the same way dark hardware does on a home.
Every Mitchell Metals canopy system is extruded aluminum, so there is nothing on the structure that rusts. Our systems are engineered to ASCE 7-16 wind and snow loads and are designed to meet ADA and IBC requirements, with layouts that follow the USPS Builders/Developers Guide for cluster box placement and approach.

Why these specs were chosen
Back-to-back configuration. Two banks of cluster boxes share one roof structure and one pad. It is the most efficient layout when a community’s mail volume exceeds what a single row of boxes can serve.
Dark Bronze finish. A factory-applied finish on extruded aluminum. It holds color, hides road dust and pollen better than lighter finishes, and coordinates with the dark exterior hardware common on new residential construction.
6×6 posts and beams. A heavier structural profile than the minimum required, chosen for durability and for the visual weight it gives the structure.
Turnkey delivery. One vendor for the boxes and the cover means one submittal, one schedule, and no gap between two trades at the end of a project — which is usually when mail centers get built.
Frequently asked questions about this project
Who built the mail kiosk cover at Saluda Springs in Greenwood, SC?
Mitchell Metals, LLC of Marietta, Georgia manufactured and installed the CBU mail kiosk cover at Saluda Springs. Mitchell Metals supplied both the cluster box units and the pre-engineered aluminum canopy as a single turnkey package.
Who is the builder of the Saluda Springs community?
Saluda Springs is a Smith Douglas Homes community located in Greenwood, South Carolina. Andrew Kern, PMP, served as project manager for Smith Douglas Homes on the development.
What are the specifications of the Saluda Springs CBU canopy?
The structure is a 12-box back-to-back CBU cover finished in Dark Bronze with 6×6 posts and beams, fabricated from extruded aluminum. It is rated for ASCE 7-16 wind and snow loads and designed to meet ADA and IBC requirements.
What is a back-to-back CBU canopy?
A back-to-back CBU canopy shelters two banks of cluster box units mounted back to back under a single roof structure on one concrete pad. Residents access mail from either side. It is the most space-efficient way to serve a community whose mail volume exceeds a single row of boxes.
Does a residential development need a covered mail kiosk?
A cover is not universally required, but it protects the cluster box units from sun, rain, and ice, extends the life of the finish, and shelters residents collecting mail. Cluster box unit placement itself must follow the USPS Builders/Developers Guide and ADA accessibility requirements, and some municipalities and HOAs require a covered structure.
