ResinDek is a high-density composite flooring that offers exceptional strength, stability, and versatility for mezzanine applications. It is especially well-suited for facilities that require a solid floor capable of supporting heavy loads from pallet jacks, carts, or dollies. Installed over 20-gauge corrugated steel decking, ResinDek has a load capacity of up to 2,000 pounds. Its Acryseal surface not only provides a skid-resistant texture but also makes it easy to clean, which is especially important in warehouses and production facilities where spills, dust, and debris are common.

Available in a sleek Gray Diamond Seal finish, ResinDek is ideal for applications where you want the combination of a high load capacity and a polished, professional appearance. It’s a popular choice for interior decking in distribution centers, manufacturing plants, and other industrial environments where durability meets aesthetics. If your operations involve frequent equipment movement or heavy product storage, ResinDek can provide a balance between function and form without the higher weight of a concrete slab.

Steel bar grating, also known as welded grating, is another strong contender for mezzanine flooring, particularly in environments where ventilation, drainage, and light transmission are important. This type of flooring is made of interlocking perpendicular steel bars that provide excellent lateral support and a clean, industrial look. Because the surface is open, it allows air, heat, light, and fluids to pass through—making it a preferred choice in industries such as waste management, mining, and food processing.

One major advantage of steel bar grating is the potential for reduced fire suppression requirements. In many cases, insurance companies only require sprinklers above the mezzanine, as the open grating allows water to pass through to lower levels. This can lead to cost savings during construction while still maintaining safety standards. Additionally, the durable, low-maintenance nature of steel bar grating makes it well-suited for facilities that need a long-lasting solution that stands up to tough environments.

For facilities that demand a high level of durability but don’t require the full weight and permanence of concrete, diamond plate flooring is an excellent choice. Heavy-duty steel tread plate is typically installed over Advantech, which in turn is mounted over corrugated steel decking. This layered approach provides greater point load and wheel load capacities while keeping noise levels lower than having diamond plate directly over steel.

Diamond plate offers a textured surface that provides added traction, making it suitable for environments where slip resistance is a concern. It’s often used in industrial plants, automotive workshops, and material handling facilities where both durability and safety are top priorities. Consider diamond plate if your mezzanine will see heavy traffic from forklifts, pallet jacks, or rolling carts, but you want to avoid the permanent installation and higher costs associated with concrete.

Concrete is the most durable mezzanine flooring option available and is commonly used in high-capacity industrial, military, and permanent warehouse applications. Its high point load capacity makes it ideal for supporting extremely heavy equipment or bulk storage. Additionally, concrete transmits minimal noise through the deck, creating a quieter work environment for the levels below.

Installing a concrete mezzanine involves pouring up to a six-inch slab over steel decking with pour stops. This makes it a heavier and more permanent solution than the other flooring types discussed here. While concrete requires a larger upfront investment and additional structural considerations, it offers unmatched durability and longevity. For facilities planning long-term, high-demand operations, concrete can be the most cost-effective choice over time.
