When it comes to construction, not every steel decking type is created equal. Depending on your structure’s purpose, load requirements, and building environment, the best steel decking type for your project can vary. If you’re not well-versed in the industry, figuring out which steel decking type you need might feel overwhelming. That’s why we’ve created this quick and easy guide — to walk you through the most common types of steel decking and help you choose the right solution for your build.
Let’s break it down.
Roof Decking
One popular steel decking type is roof decking, used in nearly all commercial and industrial roofing applications. It’s made from galvanized steel or aluminum and comes in multiple thicknesses. Roof decking provides a strong foundation for roofing materials, making it essential for structural support. It’s also lightweight, durable, and fire-resistant — which is exactly what you want overhead. If you’re working on a building where the roof needs to handle weather and weight, this steel deck type is a go-to.
Composite Decking
Another highly requested steel decking type is composite decking. It combines steel and concrete to deliver a powerful mix of strength and load-bearing capacity. This type is often used in parking structures, bridges, industrial buildings, and multi-story facilities. Composite decking can support heavier traffic and comes with excellent fire resistance. A popular brand we carry at Drexel Supply is Vulcraft — a leader in composite steel decking solutions. If you’re looking for strength and durability, this steel decking type delivers.
Form Decking
Form decking is a steel deck type made to temporarily support wet concrete during the pouring process. It’s not designed to be the final support structure but is vital for shaping concrete slabs. Lightweight and easy to install, this decking type is commonly used in floor systems where concrete is the final surface. Galvanized steel ensures added corrosion resistance, making this a practical choice for fast-paced job sites.
Mezzanine Decking
If you’re looking to expand upward without building out, mezzanine decking is the steel deck type for the job. It’s used to create extra floorspace in warehouses, factories, and large storage buildings. It’s made from galvanized steel, comes in multiple sizes and thicknesses, and is easy to install. This steel decking type is ideal for adding square footage without expanding your footprint.
Acoustic Decking
Need to manage sound in your space? Acoustic decking is the steel deck type engineered for that. Found in concert halls, movie theaters, recording studios, and other acoustically sensitive spaces, this type dampens noise and vibration. It delivers strength while helping to maintain the right sound environment inside your building.
Cellular Decking
Looking for insulation and structural strength in one product? Cellular decking is a steel deck type with a built-in solution. Its closed-cell or “honeycomb” structure improves both thermal and sound insulation, making it a smart choice for schools, hospitals, and energy-efficient commercial spaces. It keeps buildings quiet and comfortable, all while performing as a stable structural component.
Choosing the Right Steel Decking Type
When planning your next project, choosing the right steel decking type is critical to meeting your performance, safety, and budget goals. Whether you need load-bearing strength, sound insulation, or thermal performance, there’s a steel decking type that fits the bill.
