Architectural Aluminum Channel

Sapa Extrusion, the world’s premier soft alloy aluminum extruder, supplies aluminum extrusion stock for virtually every industrial and consumer market. We are pleased to offer a full range of architectural aluminum channel profiles for residential and commercial building, manufacturing, electrical and other industries.

Architectural aluminum is used when appearance is more important than strength. Extruded architectural channel has sharp, 90 degree angle inside and outside corners and is used in light weight cosmetic applications. In contrast, structural channel focuses primarily on strength over appearance; it will have a less finished look and more rounded corners.

Many different aluminum profile shapes are referred to as channels; however they generally fit into several widely-used categories. These shapes include C-channel and U-channel (the most common architectural channels), J-channel, square and rectangular open seam tubing, hat channel, and almost any other unusually shaped aluminum extrusion profile for which there is no other name, such as Z-channel.

Aluminum channel is considerably less expensive than wood, lighter in weight, insect resistant, and resists warping and cracking from water damage.

Architectural Alloy 6063

Sapa produces alloy 6063, one of the most popular alloys in the 6xxx series, for standard architectural shapes, custom solid shapes and heat sinks, as well as seamless and structural tube and pipe. It is a softer and more formable alloy than 6061, and may require special packaging to protect critical exposed surfaces.

In its heat-treated condition, alloy 6063 provides good corrosion resistance, including resistance to stress corrosion cracking. It is easily welded or brazed by various commercial methods and, while it can be machined, 6063 alloy does not machine as well as harder alloys like 6061.

6063 aluminum channels are typically produced with extremely smooth surfaces that make it easier to anodize or paint, such as in the -T5, -T52, -T53 (matte finish), -T54, -T56 (lustrous finish) tempers. The most common methods are clear, clear and color dying, and bright dipping and hard coat. Bright dipping provides a cost-effective alternative to mechanical polished finishes and offers improved surface durability.

Common uses for architectural channel include:

•interior and exterior architectural trim
•window and door frames
•aluminum casements
•sliding glass doors
•framework
•awnings
•roofs
•elevators
•framing for signs
•furniture
•railings
•glass and mirror projects
•store fixtures
In the -T5, -T52, and -T6 conditions, alloy 6063 is also used for electrical applications because of its good electrical conductivity.

Sapa Extrusions has 23 locations and 68 extrusions presses across North America, and offers the industry’s broadest product capabilities in press sizes and tonnages (direct and indirect extrusion), alloy selection, circle sizes, profile types and “green” billet.
