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.

 
 
Understanding Foundation Post
Options
2-Sided

With the 2-Sided option, designs will be printed on both sides of the strong materials with a build in block out feature to ensure durability and full opacity blocking the design from seeing through from other side.

For 2 sided banners, we use 18 oz heavy weighted vinyl. 

Keep in mind: If the design contains an arrow element, be aware the front and back must have different files with the arrow flipped to show opposite arrows in each file. 

Custom Shape

Your sign can be in any shape you can imagine!

Try our New Custom Shape Tool in Design Studio, you can create a unique shape contour with your logo shape within minutes! 

If you prefer to set up the shape line in Adobe Creative Suite, please follow our Design Guidelines, Our Design Studio will be able to display your cut lines instantly:

  • Format should be vector based PDF.
  • All cut lines should be 1pt (.0156”) strokes with the Spot Color named of “SHAPECUT”. 
Reflective

Reflective option is produced an engineer-grade 3M vinyl film with 7 mil thickness. When light hits the material, it reflects, drawing attention to your sign. Great for advertising at night. The most important thing to know is that the entire white film we print on is coated with reflective elements. That means that as more ink is printed on your piece, it becomes less reflective. 

Tip: Light colors typically work best. You’ll want to stay away from full-image backgrounds and lots of dark tones. White space is your friend and will ensure your final piece is as reflective as possible.

Rounded Corners

Elegant Design:  This subtle design choice enhances professionalism while maintaining aesthetic appeal.

Improve Longevity: Round corners extends the lifespan of the magnetic signs by minimizing the risk of peeling corners and air gaps between the magnet and your vehicle to ensure a secured strong hold so it Won't Fly Away. 

Safe & Easy Handling: Smooth edges reduce the risk of cuts and scratches and minimize damage if dropped, making them ideal for rigid materials like metal, clear acrylic, or 3mm PVC.

Rounded Corner Radius: 1/2 inch

Shape Die-Cut

Pick from 8 different Standard Shapes, say good bye to the ordinary rectangle signs! 

It will transform the entire shape of your final product to an eye catching shape.

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

  • New development coming soon signs

Foundation Post File Preparation

Design Guidelines

Have a design file ready for print? We recommend that you review the following guidelines before placing your order.
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
Other accepted file types:
.PNG, .TIF, . BMP, .GIF, or .JPG
