When it comes to modern construction, extruded aluminum really stands out for its impressive strength-to-weight ratio. In other words, you get a material that’s tough and reliable, but without the heavy burden that comes with steel or wood.

Extruded aluminum is basically aluminum that’s been pushed through a specially shaped die to create a continuous profile with a uniform cross-section. In a nutshell, it’s a process that turns raw aluminum into practical shapes that you’ll find everywhere—from construction and transportation to manufacturing and beyond. What makes extruded aluminum stand out is its strength, versatility, and how easily it can be adapted for specific uses, especially when it comes to building envelopes, facades, and a variety of aluminum systems.

When designing multi-story facades, every specification decision can mean the difference between a smooth approval process and weeks of back-and-forth with plan reviewers. Fire performance is often one of the most scrutinized aspects, and it’s where aPlank delivers clear advantages.

We’re excited to share some important news: aPlank’s Aluminum Siding with woodgrain finish has officially achieved a Class A rating in ASTM E84 testing, one of the most recognized fire performance standards in the building industry.

At aPlank, we believe great building envelopes start with collaboration. That’s why we’re excited to share our co-branded partnership with DuPont™ ArmorWall™ Systems, a powerful combination that delivers design flexibility, fire resistance, and superior performance in a single assembly.

Learn what exterior cladding is, explore material options, and discover how it enhances building durability, energy efficiency, and curb appeal.

Discover the best external wall cladding materials for durability, insulation, aesthetics, and energy efficiency. Ideal for residential and commercial projects.

A building facade is the exterior skin of a building, protecting from weather, reducing noise, saving energy, and shaping its visual identity.

When it comes to commercial construction, fire safety isn’t just a box to check—it’s a real priority that protects lives and property. In the United States, fire tests and standards are the backbone for making sure exterior walls can handle the heat, quite literally.
