1 1/2" Composite Decking
Home / 1-1/2″ Composite Decking
Strength and seamless concrete integration for commercial construction.
Achieve structural strength, durability, and cost-efficiency with CWJ Joist and Deck’s 1 1/2″ Composite Decking. Engineered to support concrete floor systems in low- to mid-rise construction, our decking is designed to handle demanding environments while integrating seamlessly with poured concrete slabs for enhanced structural performance.
Ideal for commercial, office, multi-family, and light industrial projects, our 1 1/2″ composite deck provides a reliable solution where structural depth is limited but performance is essential.
What is 1 1/2" Composite Decking?
1 1/2-inch composite decking refers to a steel deck panel with a profile depth of 1.5 inches, specifically designed to act compositely with concrete. When concrete is poured and cured over the steel deck, the two materials bond together to form a strong, fire-resistant floor system.
CWJ Joist and Deck manufactures 1 1/2″ composite decking to optimize structural efficiency, reduce material usage, and streamline installation. It is a practical solution for projects that require strength within tighter structural depths.
Key Features of CWJ Joist and Deck’s 1 1/2" Composite Decking
Efficient Load Performance
Our 1 1/2″ composite deck is engineered to support moderate live and dead loads commonly found in office buildings, multi-family housing, and light commercial spaces. When combined with concrete, it creates a composite slab system that distributes loads effectively while maintaining structural integrity.
Corrosion-Resistant Galvanized Steel
Manufactured from premium galvanized steel, our decking resists corrosion and environmental wear. The protective zinc coating enhances durability, making it suitable for interior applications and controlled exterior conditions.
Optimized Low-Profile Design
With a 1.5-inch profile height, this deck is ideal for projects where floor-to-floor height is limited. Ribbed flutes enhance the bonding surface between steel and concrete, improving composite action and long-term performance. Optional embossing is available to further strengthen concrete adhesion.
Fire Resistance
When paired with concrete, 1 1/2″ composite decking provides natural fire resistance. Optional fire-rated coatings are available to help meet building code requirements and increase safety in commercial structures.
Engineered for Efficiency and Long-Term Performance
Our 1 1/2″ composite decking is manufactured using high-quality galvanized steel and produced to meet strict structural performance standards for commercial and light industrial construction. Each panel is precision roll-formed to ensure consistent dimensions, accurate flute geometry, and reliable structural integrity across every order. The galvanized zinc coating provides long-term corrosion resistance, helping protect the deck from moisture exposure and environmental wear over time.

Reliable Solutions for Commercial Floor Systems
1 1/2″ composite decking is a practical and efficient solution for a wide range of commercial and light industrial applications. Designed for projects where structural depth is limited, it delivers dependable strength, fire resistance, and long-term performance when integrated with concrete. Its lower profile makes it especially well-suited for office buildings, multi-family developments, educational facilities, and mixed-use construction where floor-to-floor height matters. Whether you’re planning new construction or upgrading an existing structure, our 1 1/2″ composite decking is engineered to meet your structural demands while improving installation efficiency and overall project value.
Supports residential floor systems in apartments and mixed-use developments.
Reliable for classrooms and administrative spaces requiring moderate load capacity.
Seamless Installation for Maximum Performance
01
Preparation
Our team ensures that each 2" deck panel is cut to precise lengths based on project specifications, reducing on-site adjustments.
02
Placement
The decking is laid on steel frames or joists, serving as a formwork for poured concrete.
03
Concrete Pouring
Once in place, concrete is poured onto the deck, bonding with the steel profile to create a unified structure.
04
Shear Stud Installation
Shear studs may be installed to anchor the deck firmly to the steel beams, reinforcing composite action.
