Building your own SEG frame starts with the right materials, and for professionals who fabricate in-house, it begins with raw aluminum extrusions. Unlike ready-made kits or assembled frames, SEG frame fabrication gives you complete control over the size, hardware, and finish. It also requires specialized tools, fabrication knowledge, and precise cutting. This is a job for fabricators, not first-time users.
At Testrite Aluminum, we supply the building blocks. We manufacture and stock raw aluminum SEG extrusions in full lengths, ready for cutting and assembly by experienced frame fabricators. We do not sell complete frame kits or pre-cut segments. Our customers are professionals who know how to measure, miter, and build frames on-site or in-shop to meet their project needs.
In this piece, we will discuss how to build your own SEG frames using raw aluminum extrusions, the tools and materials required, and what to consider before placing your order.
What Are SEG Frames Used For
SEG frames, also known as Silicone Edge Graphic frames, are widely used in commercial environments where clean, large-format visuals are required. They are most commonly seen in retail displays, trade show exhibits, office branding, and interior signage. The frame features a fabric graphic with a silicone edge that fits snugly into a narrow groove in the aluminum extrusion, resulting in a smooth, frameless appearance.
Due to their ability to hold tensioned graphics without visible hardware, SEG frames are ideal for applications where visual impact is crucial. Businesses use them to display promotional campaigns, branded environments, seasonal messaging, or backlit visuals. The frames can be wall-mounted, freestanding, or suspended, depending on the installation style and hardware used.
While the final product is sleek and minimal, behind the scenes, SEG frames require precise fabrication to deliver the clean edge and tight fit. That is why professional installers, fabricators, and sign shops often build these frames themselves using raw materials tailored to their specific needs.
Two Ways to Get SEG Frames
There are two primary ways to source SEG frames, and understanding the difference is essential before placing an order.
The first option is to purchase fully fabricated ready to assemble SEG frames. This is ideal for customers who want a ready-to-install solution without needing to handle any fabrication. These complete frames are available from Testrite.com, where cutting, mitering, and hardware installation are completed before shipping.
The second option is for fabricators and companies that prefer to build their own SEG frames. That is the purpose of TestriteAluminum.com. This site offers raw SEG aluminum extrusions in full-length sticks, typically 72 inches or up to 12 ft extrusion lengths. These extrusions are not mitered and do not include mating hardware hardware. They are sold for customers who have the equipment and experience to cut, miter, and assemble frames as needed.
When you buy from Testrite Aluminum, you are purchasing materials, not finished products. This allows for complete control over the frame size and build process, but it requires proper tools and knowledge to complete the job effectively.
Choosing the Right SEG Extrusions
The first step in building your own SEG frame is selecting the right extrusion profile for your application. Different extrusions are suited for different display styles, whether you are building a wall-mounted frame, a freestanding unit, a double-sided graphic display, or a fabric lightbox.
Testrite Aluminum offers a complete line of precision-engineered SEG extrusions in anodized and mill finish lengths. These include options like shallow wall profiles for low-profile installations and deeper profiles that support larger graphics or internal supports. Some extrusions include channels for LED lighting, while others are better suited for standard edge-lit displays.
To choose the correct extrusion, consider the following:
-
Will the frame be mounted to a wall, freestanding, or suspended?
-
Does the frame need to be single-sided or double-sided?
-
Will it be backlit or non-lit?
-
What size and scale are you working with?
Once you answer these questions, you can browse our Charisma SEG extrusions and graphic holding extrusions to match the profile to your project. Please note that these extrusions are sold in full-length sticks and must be cut before use.
What Tools and Equipment Will You Need
Fabricating SEG frames from raw aluminum extrusions requires the right tools and a correctly set-up workspace. Since Testrite Aluminum sells full-length sticks of extrusion, you will be responsible for cutting, mitering, and assembling the materials yourself.
To begin, you will need an adjustable angle chop saw or miter saw equipped with a non-ferrous blade rated for cutting aluminum. Accuracy is key, especially when making miter cuts for clean corner joints. Always follow all safety precautions, including using eye protection, hearing protection, and a secure cutting surface.
Additional tools and equipment you may need include:
-
Allen keys or hex drivers for tightening corner connectors
-
A workbench or flat assembly surface
-
Measuring tape or calipers for precise cuts
-
Clamps or jigs for holding extrusions during cutting
-
Deburring tools to clean up sharp edges after cutting
- Drill and bits capable of drilling holes into the aluminum extrusion (eg for bases).
If you are incorporating accessories such as wall mount brackets, base plates, or support bars, make sure your tools are compatible with the fasteners and hardware being used.
Fabricating SEG frames is not a beginner project. This process is intended for professionals and businesses with experience in handling aluminum, shop tools, and precision assemblies.
How to Fabricate SEG Frames from Extrusion Lengths
Once you have selected your extrusion type and gathered the necessary tools, you are ready to begin fabricating your SEG frame. This process requires attention to detail to ensure a precise fit for the graphic and secure assembly.
Step 1: Measure and Mark
Start by measuring and marking your cut lengths based on the finished frame size. If you are mitering the corners, account for the 45-degree cuts at each end of the piece.
Step 2: Cut the Extrusions
Use a chop saw or miter saw with a non-ferrous aluminum blade to make straight or angled cuts. Ensure the saw is stable and clean the cut ends with a deburring tool to remove any sharp edges or metal shavings.
Step 3: Install Corner Connectors
Slide the corner brackets into the ends of the extrusion and secure them in place using the appropriate hardware. Most SEG corner connectors are secured with set screws, which can be tightened using an Allen key.
Step 4: Assemble the Frame
Connect all four sides of the frame on a flat surface. Check for squareness by measuring diagonally across opposite corners. Adjust if needed to ensure the frame is even.
Step 5: Add Support and Mounting Hardware
If your frame requires a center support bar, install it using spanner bars and quick-connect hardware. Add any necessary mounting brackets or base plates, depending on whether the frame is wall-mounted, freestanding, or hanging. This step may involve drilling holes.
Step 6: Install the Graphic
Once the frame is assembled, the silicone edge fabric graphic can be pressed into the extrusion channel, starting with each corner and then working along the sides.
The result is an entirely fabricated SEG frame, built to your exact specifications using raw materials from Testrite Aluminum.
Selecting the Right Accessories and Hardware
The performance and stability of your SEG frame depend not only on the extrusion but also on the accessories you select during the fabrication process. These components help you connect, support, and install the frame according to its intended use and location.
Here are some of the most commonly used accessories for SEG frame builds:
-
Corner Brackets: Essential for connecting extrusion ends at a 90-degree angle. These are used for both mitered and straight-cut corners and are secured using set screws.
-
Wall Mount Brackets: When creating a wall-mounted frame, you will need brackets that securely attach the frame to the surface while maintaining a flush appearance.
-
Base Plates: Freestanding frames require stable bases. Choose the correct size and weight based on your frame dimensions and the environment where it will be placed.
-
Spanner Support Bars: Larger frames may require internal support to maintain tension and prevent bowing. These bars run horizontally or vertically (or both!) across the frame, providing added stability.
-
Quick Connect Hardware: Utilized with spanner bars or other internal structures, quick connects enable fast and secure assembly without the need for custom fabrication.
When planning your project, think about how the frame will function in its final location. This will help you select the correct combination of hardware. All accessories can be ordered directly through Testrite Aluminum, along with your extrusion lengths, giving you everything needed for custom fabrication in one place.
Always make sure your frame is fully stable as built and installed, before leaving it, what you build on your own it’s at your own risk
