Sapa Extrusion offers structural aluminum framing systems for any application in the residential, industrial and commercial building industries. As part of the world’s largest aluminum profile company, we have unsurpassed capabilities in extruded aluminum shapes, sizes, alloys and tempers, including both direct and indirect extrusion methods.
Aluminum is less expensive, more versatile and more flexible than welded steel. Thanks to its enormous versatility, aluminum extrusions are ideal in a wide variety of framing applications, such as:
machine bases and frames
material handling fixtures
perimeter safety fencing
material handling carts
clean room applications
office workstations and enclosures
Benefits of Aluminum for Structural Frames
Aluminum is lighter than iron and steel, and some alloys are stronger than some steel alloys. This makes the metal important for the frames and bodies of aircraft, cars, trains and boats where the strength-to-weight ratio is critical. In fact, nearly 70% of the components of commercial aircraft are made of aluminum alloys. But weight and strength are not the only factors to consider.
The natural metallic surface of aluminum is aesthetically pleasing as-is. It needs no further finishing, but can be anodized, painted or powder-coated if desired.
Aluminum does not emit sparks and is a great choice in highly flammable environments.
Extruded aluminum components resist the distortion caused by weather and building movement. They retain strength and flexibility under loads and spring back from the shock of impact.
Complex shapes can be obtained in one-piece extruded sections so mechanical joining is not required. The result is that the frame components are more durable and less likely to loosen over time.
Aluminum extrusions can be joined to other aluminum products or to different materials by all key methods, including welding, brazing, soldering, bolting, riveting, bonding, and snap together or interlocking joints.
Aluminum is highly resistant to rust and corrosion as a result of its thin, naturally occurring, impenetrable protective aluminum oxide film.
Steel has to be painted or treated to protect it from rust and corrosion, especially if used in a moist, damp or abrasive environment, and wood requires scraping, sanding, painting or staining. Aluminum never needs to be refinished.
Some of the most popular aluminum framing components are T-slot extrusions. They feature one or more long, narrow slots that travel along the length of the extrusion, and the profiles allow for positioning of panels or screens anywhere along the axis. T-slotted profiles can be fabricated with one to four slots per side, leaving the other side(s) smooth. Some profiles have thicker walls, making them well-suited to structures with very high load requirements.
T-slots are connected with standard fractional or metric tools and anchor fasteners, corner brackets and joining plates, and no welding is necessary. T-slotted extrusion systems are quick to assemble with standard tools. They resist torque and bending better than standard square aluminum extrusions, so they maintain their shape and strength. T-slots operate like modular aluminum building blocks, allowing for economical frame building by easily positioning fasteners, panels and other components or accessories.
Sapa Extrusions operates 23 facilities and 68 extrusion presses across North America, and offer the industry’s broadest product capabilities in press sizes and tonnages, alloy selection, circle sizes, profile types and “green” billet.
We have the capability of taking your aluminum framing project from conception to prototype to production.
