2 Types of Custom
Materials
01
ACM Metal
Thicker, Stronger & Cheaper

Aluminum Composite Material (ACM) Metal is a new, popular type of metal with good stability, light weight, and a sleek look.

ACM Metal is created with a three-layer sandwich panel consisting of two pre-painted .015mm aluminum sheets bonded to a black polyethylene (PE) core, giving it a total thickness of 0.125 inches. These layers make ACM Metal stronger than standard aluminum and ensure it remains flat after installation, even in extreme temperatures.

The best part? ACM Metal comes at a great price point when compared to aluminum.

02
Aluminum
Solid Metal, Build to Last.

Our Premium Aluminum is made with real metal and has a solid 0.040 thickness. 

With superior corrosion resistance, your aluminum signs are waterproof and rustproof, so you know they will last for years to come, no maintenance required. Aluminum also offers strength and malleability, making it much less likely to bend and easier to transport. 

Aluminum is fully recyclable, so you can feel good knowing your purchase is helping to protect the environment.

Foundation Posts for Commercial Real Estate Signs: Built for Visibility and Durability

Make your commercial property stand out with professional-grade foundation posts designed for large-format outdoor signage. Whether you're marketing a retail space for lease, an office building for sale, or a new development coming soon, our heavy-duty 4×4 post system delivers the curb appeal and durability your listing deserves.

Engineered for Commercial Signage

Our foundation post system supports metal signs, aluminum signs, and ACM panels up to 96" × 96"—perfect for high-visibility commercial real estate marketing. The pressure-treated lumber construction resists rot, decay, and weather damage, ensuring your investment property signage stays looking professional for years.

Flexible Configurations for Every Property

Choose the setup that fits your site:

Single Sign Setup (2 Posts) – Ideal for storefronts, standalone buildings, and roadside visibility. Mount one large sign facing traffic, or install two signs back-to-back for dual-direction exposure on busy streets and corner lots.

Dual Sign Setup (3 Posts) – The triangle configuration positions two signs at an angle, maximizing visibility from multiple approach directions. Perfect for high-traffic intersections, shopping centers, and commercial developments where you need to capture attention from both sides of the road.

Professional Installation Made Easy

Each kit includes pre-drilled pilot holes spaced every 12 inches for fast, accurate sign mounting. Simply dig 18" deep holes, set posts in concrete, and secure your sign with the included hardware. The 8-foot posts provide 18" ground clearance—keeping your message visible above landscaping, snow, and foot traffic.

Why Commercial Property Managers Choose Foundation Posts

Unlike temporary sign stakes or flimsy H-frames, foundation posts create a permanent, professional presence that reflects the quality of your property. The sturdy ground-mounted design withstands high winds, storms, and heavy signage without tilting or falling—protecting your brand and your investment.

Ideal For:

  • Commercial property for sale signs
  • Retail space for lease signage
  • Land for sale displays
  • Office building marketing
  • Industrial property listings
  • New development coming soon signs
  • Shopping center directory signs

Total File Size With Bleed (H x W):
Finished Product Size (H x W):
Understanding File Setup
Bleed Area Add 0.125in.
Extend your background to fill the full "bleed area." This will make sure you do not end up with white edges when your product is cut.
Finished Project Size What you selected on this page
This is where we aim to cut your final product size.
Safe Zone Inset 0.125in.
Keep all of the important elements of your design-text, logo, icons-inside this area. It's okay for backgrounds and images to run all the way to the bleed area.
What type of files will you accept?
We recommend vector-based .PDF design files. Most major design applications can generate a print-ready .PDF by using the Save As feature and selecting “Adobe PDF.” If you are unable to obtain a .PDF file for your design, the best are those in .EPS or .AI (CS3 or higher) format with all text converted to outlines.
Recommended file types:
Vector-based .PDF, .PS, .PSD, or .EPS. Vector-based Adobe Illustrator .AI
