Introduction Aluminum Extrusions are a preferred material for commercial construction due to their unique combination of attributes: • Lightweight strength • Design flexibility • Longevity, and low maintenance • Sustainability – infinite recyclability and high recycled content potential
With this highly workable material you can create – not choose – shapes that yield functionality and aesthetics, while providing superior cost effectiveness and sustainability.

Introduction Some of the applications for aluminum extrusions in commercial buildings: •
Fenestration • Windows and doors (including hurricane- forced entry– tornado- and blast-resistant) • Store Fronts & Curtain walls
•
Energy Management • Sun shades and louvers • Light shelves • Photovoltaic panel framing, mounting
•
Skylights & Canopies • Sun rooms • Atriums and enclosures • Observatories • Gates & archways 9
Introduction Some of the innovative applications for aluminum extrusions in commercial buildings: • Structure • Bridge decks • Canopies • Space frame systems • Garages and parking covers • Geodesic domes and structures • Interior elements • Panel systems and cubicles • Elevator cab framing • Light housings & grids • Demountable interior walls • Railing systems • Decorative screens • And more… While aluminum extrusions are often a predetermined element in a building product, custom shapes can peak the imagination of designers and architects …

Overview Aluminum Extrusion combines: • a material with outstanding physical characteristics • a process that is incredibly versatile, capable of converting ideas to reality quickly and inexpensively, creating near-net shapes for complex forms, with close tolerances Together, the metal and the process optimize component and product designs!

Overview Advantages of Aluminum
Advantages of Extrusion
• Lightweight
• Tailored performance – put metal where
• Strong
it is needed
• High Strength-to-Weight Ratio • Resilient • Corrosion-Resistant • Heat Conductive
• Suitable for complex, integral shapes, produced to close tolerances • Attractive, wide range of finishes
• Reflective
• Virtually seamless
• Electrically Conductive
• Easy to fabricate
• Non-Magnetic
• Joinable by various methods
• Non-Sparking • Non-Combustible • Cold Strength • Fully Recyclable
• Suitable for easy-assembly designs • Produced with uniform quality • Cost Effective • Short production lead times 16
Overview – the material Strong, with high Strength-to-Weight Appropriately alloyed and tempered, aluminum is stronger than some steels, with ultimate tensile strengths as high as 80,000 psi to 90,000 psi or more.
The standard aluminum frame for the 2014 Corvette C7 is over 90 pounds lighter, yet 60% stiffer than the previous steel frame
17
Overview – the material Corrosion-Resistant
Cold Strength
Aluminum develops its own inert aluminum oxide film, which is selfprotective, blocking further oxidation.
•
•
Aluminum is not impaired by cold, gaining strength and ductility as temperatures are reduced; a preferred metal for cryogenic (low-temperature) applications. Steel and plastics get brittle when the temperature drops… aluminum gets stronger and tougher!

Overview – the material Electrically Conductive
Heat Conductive
Volume for volume, aluminum carries electricity about 62% as well as copper. On a weight basis, aluminum can be twice as conductive as copper, and aluminum is often the most economical choice.
Conducts – and dissipates - heat better than any other common metal on both a weight and cost basis.

Overview – the material Sustainable & Fully Recyclable • Can be recycled over and over without degradation of its innate properties • Recycling requires only 8% of the energy necessary to produce virgin aluminum • Extrusions can contain as much as 80%, recycled content. • In 2014, North American extruders will utilize > 2.5 Billion pounds of scrap!

Overview – the process The Extrusion Process - how are HOLLOW Shapes Extruded? The PlayDoh flows through the opening between the part of the die that forms the outside diameter and the inside “mandrel” supported by two horizontal supports.
The PlayDoh SEPARATES into two tube halves and “welds” back together due to the pressure needed to make it flow through the annular opening into a tube shape.
23
Overview – the process Suitable for Complex, Integral Shapes
Produced to Close Tolerances
• Shapes can combine functions that would otherwise require the production and joining full extruded lengths are routine and the of several different parts, reducing part ability of aluminum extruders to meet even counts and costs. more critical dimensions is keeping pace with advances in technology.
• The ability to hold tight tolerances over the

Overview – the process Accepting a Wide Range of Finishes
Simplified Fabrication & Assembly
Aluminum extrusions accept a great variety of finishes, colors and textures (anodize, alodine, wet or powder paint, applique, etc.)
• Creative Design with aluminum extrusions
can eliminate fabrication and assembly steps •.Parts can be easily cut, machined, finished, bent, welded, fabricated and assembled.
25
Overview – the process Cost-effective
Time-effective
• The diversity of shapes permitted by the extrusion process cuts down or eliminates many machining and joining operations.
• Extrusion’s short lead times facilitate design iteration and the use of custom shapes to create an effective design solution
• Tooling costs are modest in comparison with other processes.

Key Design Variables - Finishing
•
Anodizing: an electrochemical process that converts the aluminum surface into a decorative, durable, corrosion-resistant, anodic aluminum oxide finish.
• Painting: a variety of liquid or power resin formulations typically applied electrostatically in either horizontal or vertical paint lines. Courtesy of PFOnline.com
55
Key Design Variables - Finishing Anodizing has significant benefits … •
Durability. Most anodized products have an extremely long life span and offer significant economic advantages through maintenance and operating savings.
•
Ease of Maintenance. Scars and wear from general use (fabrication, handling, installation, frequent surface cleaning) are virtually nonexistent. Rinsing or mild soap-and-water cleaning usually will restore an anodized surface to its original appearance. Mild abrasive cleaners can be used for more difficult deposits.
•
Color Stability. Exterior anodic coatings provide good stability to ultraviolet rays, do not chip or peel, and are easily repeatable.
