Standard Aluminum Decking Boards
Standard aluminum decking boards look like traditional wood decking but without the maintenance. They have small gaps between them so you have design flexibility, but with aluminum’s durability.
Many systems have hidden fasteners so the surface is smooth and clean with no visible screws or nails. These options give you design choices while keeping the benefits of aluminum.
Finish Options and Aesthetic Choices
Modern aluminum decking has many finish options. Powder coating is the most common, it’s durable and has almost unlimited color options. These finishes are designed for outdoor use so color will not fade.
Aluminum decking can also have wood grain finishes, looks like wood without the maintenance. These finishes help aluminum decking fit any architectural style so it’s suitable for any design while keeping the practical benefits.
Aluminum Decking Benefits
Durability
Aluminum decking lasts longer than wood decks. It doesn’t warp, crack or rot. High grade aluminum alloys like 6005-T5 and T6 6063 are super strong and stable. Aluminum decking holds up in high traffic areas and extreme weather conditions.
Aluminum doesn’t shrink or expand with moisture like wood does. Powder coated finishes last for decades.
Low Maintenance
Aluminum decking is low maintenance compared to wood decking. Just wipe down with mild soap and water and you’re done. No annual re-finishing, no insect treatments, no mold prevention. Perfect for commercial spaces and vacation homes.
Weather Resistance
Aluminum decking withstands the elements better than traditional materials. Powder coated finishes protect from UV and color fade. Aluminum won’t rot or weaken when wet. Some systems have water diverting channels for dry spaces under elevated decks. Aluminum decking also resists salt spray, making it perfect for coastal areas.
Fire Safety
Aluminum decking is non-combustible and stops fire from spreading. It has a Class A fire rating with a flame spread of 0. Composite materials can’t compete with that. Many aluminum decking products meet strict fire safety codes for balconies and elevated structures. That can save you money on insurance in high-risk areas.
Sustainability
Aluminum decking is green. It lasts longer than wood so you won’t need to replace it as often. Aluminum is 100% recyclable with no loss of quality. It eliminates the need for chemical preservatives on wood decks. Choosing aluminum decking reduces long-term resource consumption.
Aluminum Decking Applications
Residential: Outdoor Spaces
Aluminum decking’s versatile looks suit many architectural styles. It can match existing or be a statement feature. For elevated decks, waterproof aluminum systems create usable space underneath, effectively doubling your outdoor areas.
This extra protected space can be storage, outdoor living rooms, or shelter for spas and kitchens, getting the most out of limited residential spaces.
Commercial and Public Spaces
In commercial areas, aluminum decking is durable, fire resistant, and low maintenance. Perfect for high traffic areas like restaurant patios, hotel amenities and public spaces.
For public spaces, aluminum decking is slip-resistant, splinter-free boards, and secure fastening systems. More safety and less liability. Fire resistance is critical in commercial areas where fire code compliance is strict.
Multi-Family and Balcony Applications
Aluminum decking shines in multi-family applications, especially for balconies, terraces and elevated walkways. Its fire resistance addresses the big safety concerns, many products have A2-s1, d0 and A2fl-s1 fire ratings that meet building regulations for multi-story buildings. No need for additional protective measures like with combustible materials.
Waterfront and Marine Environments
Aluminum decking excels in demanding waterfront environments where moisture, salt spray and extreme weather quickly ruin other materials. For docks, marinas and waterfront decks, aluminum’s corrosion resistance and structural integrity gives you safety and longevity. Many aluminum decking products pass 1000 hour salt fog tests with no damage.
Climate-Specific Applications
Aluminum decking performs well across all climate zones. In hot, sunny climates, it resists UV degradation so it won’t fade or deteriorate like other materials. With proper color selection and installation design, modern aluminum decking systems are comfortable even in high temperature environments.
In cold regions with freeze-thaw cycles, aluminum’s dimensional stability prevents cracking and structural damage like wood and composites. It’s impermeable so it won’t absorb moisture that causes frost damage, and its strength resists snow loads without deterioration.
