For architects, contractors, and developers designing multifamily buildings, hotels, restaurants, rooftop amenities, balconies, and other commercial outdoor spaces, fire-resistant decking can be an important part of the material selection process. Choosing a decking material that is non-combustible can help support a fire-conscious design while also delivering the durability and low maintenance required for commercial applications.
That is where Craft-Bilt aluminum decking stands out. Manufactured from extruded aluminum, Craft-Bilt decking provides a non-combustible decking solution for commercial projects. Aluminum doesn’t provide the same fuel source for fire as combustible decking materials such as wood and many composite products. For projects where fire performance and non-combustible construction are priorities, aluminum deserves serious consideration.
Why Fire-Resistant Decking Matters

Fire safety is an increasingly important consideration in commercial and multifamily construction. Outdoor decks, balconies, rooftop spaces, and elevated walkways can be located close to buildings, adjacent structures, and other occupied areas. The materials used in these spaces therefore need to be carefully evaluated as part of the overall building design.
Traditional wood decking is combustible. Composite decking products can also contain combustible materials. While the fire performance of individual products and assemblies varies, these materials may require additional consideration when a project has specific fire-resistance or non-combustibility requirements.
Aluminum offers a different approach.
Aluminum is non-combustible, making it an attractive option when architects and contractors are looking for decking materials that will not act as a fuel source in a fire.
Craft-Bilt aluminum decking gives designers the opportunity to incorporate a durable, attractive decking system while also addressing the importance of non-combustible construction. As with any building material, the fire performance of the complete deck assembly depends on the entire system and the requirements of the specific project. Architects and contractors should always verify applicable building codes, ratings, and assembly requirements before specifying a product.
Fire-Resistant Decking for Multifamily and Commercial Construction

Multifamily properties present unique challenges for material selection. Balconies, shared decks, rooftop gathering areas, and outdoor amenities are used by numerous residents and guests and are often located directly adjacent to occupied buildings.
In these applications, selecting non-combustible materials can be especially valuable. Craft-Bilt aluminum decking can be used in a variety of commercial and multifamily applications, including:
- Apartment and condominium balconies
- Rooftop decks
- Multifamily amenity spaces
- Hotels and resorts
- Restaurant patios
- Commercial terraces
- Elevated walkways
- Pool decks
- Outdoor gathering areas
- Mixed-use developments
By choosing aluminum decking, architects and contractors can address fire-related material considerations while also specifying a product designed for demanding outdoor environments.
Aluminum Doesn’t Just Resist Fire; It Resists the Elements
Fire-resistant decking is an important advantage of aluminum, but it is far from the only reason to choose it. Commercial decking needs to withstand much more than foot traffic. It is exposed to rain, snow, sunlight, temperature changes, moisture, and everyday wear. Over time, these conditions can cause conventional decking materials to deteriorate.
Craft-Bilt aluminum decking is designed to provide long-term performance in challenging outdoor environments. The extruded aluminum construction won’t rot, splinter, or warp like traditional wood decking can. Aluminum also eliminates many of the moisture-related maintenance concerns associated with wood. That combination makes aluminum particularly well suited to commercial projects where replacing or extensively maintaining decking can be expensive and disruptive.
Waterproof Decking for Elevated Commercial Spaces

Another major benefit of Craft-Bilt aluminum decking is its approach to water management. The decking features an integrated rain channel system that directs water away from the deck surface. The interlocking boards create a waterproof surface, helping protect the area beneath the deck from rainwater. For an elevated commercial deck or balcony, this can be a major advantage.
Imagine an apartment balcony located above another outdoor amenity area, a restaurant patio constructed over occupied space, or a rooftop deck above a finished interior space. Keeping rainwater from passing through the decking can help protect the area below while making the outdoor space more functional.
In other words, Craft-Bilt aluminum decking combines fire-resistant, non-combustible construction with waterproof performance—two important considerations for many commercial applications.
Low-Maintenance Fire-Resistant Decking

Commercial property owners also need to think about what happens after construction is complete. Decking that requires frequent staining, sealing, painting, or repairs can increase long-term maintenance costs. For large commercial properties with dozens, or even hundreds, of outdoor spaces, those maintenance requirements can quickly become significant.
Aluminum decking offers a low-maintenance alternative. Craft-Bilt aluminum decking does not need to be stained or sealed like wood, and it won’t rot or splinter. Its durable finish is designed for outdoor use, helping the decking maintain its appearance while reducing routine maintenance.
For architects and contractors, specifying a low-maintenance material can provide another long-term benefit for the property owner.
Fire Resistance Without Sacrificing Design
Fire-resistant decking doesn’t have to mean sacrificing aesthetics. Craft-Bilt aluminum decking features a clean, finished appearance and a textured, non-skid surface designed for outdoor applications. Color and finish options can be coordinated with architectural elements, railings, siding, and other exterior finishes. For modern apartment buildings, rooftop restaurants, hotels, and commercial developments, aluminum decking can provide a finished appearance that complements contemporary architecture.
Why Architects and Contractors Should Consider Aluminum
When selecting commercial decking, the question shouldn’t simply be, “What does the decking look like?” Architects and contractors need to consider how the material will perform over the life of the building. Is it combustible? How will it handle moisture? What kind of maintenance will it require? How will it perform in an exposed environment? Can it provide the durability expected in a high-traffic commercial space?Craft-Bilt aluminum decking addresses many of these considerations in one system.
Most importantly, when fire-resistant decking is a priority, aluminum offers an important advantage because it is non-combustible. Add waterproof construction, durability, low maintenance, and an attractive finished appearance, and aluminum becomes a compelling alternative to traditional decking materials.
Make Fire Resistance Part of the Decking Conversation
For commercial construction, material selection is about more than the initial installation. The right products need to support the project’s safety goals, perform in demanding environments, and provide long-term value. When fire resistance is a key consideration, Craft-Bilt aluminum decking gives architects and contractors a non-combustible option designed for commercial outdoor spaces.
