Aluminum is widely used in construction but not all aluminum is the same. Its performance depends on two key factors: composition and thickness. These variables determine how aluminum behaves in real-world building environments, from resisting corrosion to withstanding wind loads and impact. Choosing the right combination is essential for long-term performance, safety, and structural reliability.
Only a handful of alloys are typically used across architectural and structural applications. Here is a breakdown of the five most common aluminum types you’ll find in building products and how their composition affects performance.

Thickness is just as important as composition. The right alloy used in the wrong thickness can still fail, leading to denting, bending, buckling, or premature wear.
Optimal thickness varies by application:
Choosing the correct thickness ensures the alloy performs the way it was engineered to.
Many products cut costs by using alloys with unsuitable compositions or material that’s too thin for safe performance. While this may create a cheaper price point, it often results in premature corrosion, reduced structural strength, and overall poor performance leading to higher costs and potential safety issues over time.
Knotwood finds the sweet spot.
Knotwood relies on thorough research and testing to make sure every product is built with the right composition and thickness. We refuse to compromise on composition, strength, or thickness simply to offer the cheapest option. Instead, we prioritise long-term performance, structural integrity, and safety resulting in a trustworthy product that delivers consistent, dependable results in real-world conditions.
Powder coating, often considered a standard finish, can vary greatly in quality. We’ll explore how raw materials, application methods, and curing processes affect a coating’s longevity.
