What Is Extruded Aluminum?

Extruded aluminum framing is aluminum alloy transformed into cross-sectional framing called profile. The extrusions in the framing enables modular design principles to be engineered into the project. All of the T-slot aluminum profiles have inclined groove flanks engineered into the profile designs. These inclined groove flanks make up the T-slot and ensure modular connections take advantage of the controlled elastic deformation, maximizing the strength of each connection.

Why Use Extruded Aluminum Framing?

There are many reasons to use extruded aluminum framing, but these are the main reasons: strength, durability and versatility.

Framing Strength

Stronger Than You Think

A common misconception is that aluminum will not meet structural strength standards, when in fact extruded aluminum possesses a superior strength-to-weight ratio than steel. It is strong enough to handle most structural design applications. Overall the light-weight structure and structural strength provides a cost-effective framing option.

Extruded Aluminum Durability

Long-lasting Framing

T-slot aluminum is tough enough for most structural framing applications. One key aspect to its durability is unlike steel, aluminum is rust resistant. The anodized coating on extruded aluminum is a natural coating that prevents rust. Without the worry of rust, there is no need to prime or paint the aluminum profile.

Versatile T-slot Design

Build Anything

There are infinite possibilities when it comes to the design applications built with T-slot extruded aluminum. The T-slot profiles are modular in design. This means that profiles can be removed, adjusted or repositioned using the appropriate component technology. The base T-nut is the core of it all, however there are many different types of fasteners and other connection components to build pretty much anything.

T-slot Aluminum Weights

There are three profile weight classifications: Standard, Light and Economy. Each are used for their own specific applications and many times they are used cohesively. By utilizing multiple weight profiles in the design and build, you are able to save on project costs, while having a fully-functional piece of equipment.

MB Kit Systems' engineers are trained to work with you to plan and design the appropriate aluminum profile weights and lines for the specific application. Projects are never over or under engineered.

Simply put, your project will be designed with integrity and precision to ensure satisfaction every time.

Standard Aluminum Profile

Standard Profile

Standard T-slot aluminum profile is the strongest of the three profile weights. It is also the heaviest option. Standard Profiles are recommended for linear motion applications.

Most costly profile option | Heaviest-duty option

Standard Aluminum Profile

Light Profile

Light Profile offers a perfect mix of strength, tolerance and low weight attributes. It is the most popular profile weight option.

Middle-range cost profile option | Heavier-duty option

Standard Aluminum Profile

Economy Profile

Economy Profile is the ultimate light weight framing that still provides durability and strength. It is most frequently used for light duty applications or designed as an accent piece.

Lowest cost profile option | Heavy-duty option

Extruded Aluminum Profile Lines

Aluminum Profile Lines

The foundation of MB Kit Systems is the high-quality T-slotted extruded aluminum profiles. The expansive system of profiles are slow-extruded to a high straightness tolerance, enabling the MB Kit engineering team to design the most complex applications. Our profile selection includes more than 210 different variations of T-slot extruded aluminum profiles, which fall into three profile lines. These profile lines are referenced by a number corresponding to the T-slot groove dimension. This ranges from the light-duty L5 profiles up to the heaviest-duty profile, L8.

Extruded Aluminum Solutions

L8 Profile

L8 is the base design for all T-slotted extruded aluminum designs. Being robust and strong it is the most popular line of aluminum profile because the high-volume of compatible components and accessories, making L8 profiles suitable for most applications. The three profile line variants and various sizes are included with many of L8’s profile variations. Satisfy virtually all of your construction needs using L8 by configuring or adding components into the 8mm groove such as polycarbonate panels to wire mesh.

Best Uses for L8 Profile

All solutions can be built with L8 due to the wide-array of profile designs, components and structural strength.


Versatility, adaptability, strength, extensive profile & components line.

L8 Extruded Aluminum Profile

L6 Profile

Mid-range sized line with high structural strength. Profile available in Standard and Light weight options. L6’s T-slotted groove is 6mm. Included in design where specifications require a light, yet strong structure. While there are fewer options available in this size, it is a very functional line to use for the correct application.

Best Uses for L6 Profile

For crowded and compact spaces. Lightweight guarding, small enclosures and structures are common uses for this line.


Lower cost, strong, complimentary profile with multiple options.

L6 Extruded Aluminum Profile

L5 Profile

L5 is the smallest line option offered. Best used for the smallest-sized applications. Despite the dimensional size of of L5 profile being considerably smaller than L8, it is still a very structurally sound material. This line is often used in situations where high loads are not applicable. It is commonly used in conjunction with other profiles to save material cost, while meeting specified project requirements. Available with open and closed grooves for a more attractive appearance.

Best Uses for L5 Profile

Often used in conjunction with other profile lines. Small enclosures, low-load requirements, and support beams.


Lowest cost, small size, and complimentary profile option.
