CREATE BIGGER AND BRIGHTER OPEN SPACES
For projects requiring expansive, column-free interiors, Vulcraft’s long-span DLH-Series joists, custom-designed joists, dovetail deck systems, and composite joists provide versatile and economical solutions. These products enable architects and engineers to create large open areas - such as arenas, convention centers, and specialty venues - while optimizing structural efficiency and reducing material costs, as detailed in the Vulcraft Specification Guide.
EFFICIENT, FLEXIBLE, & POWERFUL
DLH-SERIES JOISTS
Vulcraft’s DLH-Series joists, also known as Deep Longspan joists, are engineered to deliver impressive unshored spans, making them ideal for projects requiring the support of larger loads over extended distances. With depths ranging from 52 inches to 120 inches and the capability to span up to 240 feet, DLH-Series joists accommodate a wide variety of structural conditions without the need for intermediate supports. This not only maximizes open space and design flexibility but also reduces the need for additional columns or load-bearing walls, resulting in more efficient and cost-effective building layouts. Their robust open-web design further allows for the integration of mechanical, electrical, and plumbing systems, enhancing the overall utility and value of the structure.
REACH MAXIMUM UNSHORED SPANS
DOVETAIL DECK
The next generation of Dovetail Deck achieves impressive unshored spans through a combination of innovative engineering and advanced profile design. Its re-engineered dovetail geometry extends unshored clear spans and increases load capacity, making it ideal for projects demanding wide, unobstructed spaces such as educational facilities, healthcare buildings, and multi-story residences. The new 2.0” profile, offered in a 30” wide panel, means fewer bundles and panels are needed, streamlining installation and reducing labor costs while supporting longer unshored spans. Additionally, the deck’s compatibility with composite beam design and the integration of patent-pending, tightly snapping sidelaps ensure structural integrity and a seamless finish, further enhancing its ability to deliver large unshored spans with efficiency and reliability.
STRONG, SUSTAINABLE CONSTRUCTION
COMPOSITE JOISTS
Vulcraft’s composite joists deliver open-space solutions by enabling maximum unshored spans, creating large, column-free areas ideal for flexible building layouts. These joists combine the strength of an open web steel system with a concrete slab, forming a unified structure that efficiently handles heavy loads and exhibits greater stiffness than conventional joist systems. The integration of steel and concrete reduces the amount of material required, lowers floor-to-floor heights, and decreases the overall environmental footprint of construction projects through reduced material use and shipping needs. This results in cost savings, faster construction timelines, and more sustainable buildings, making Vulcraft’s composite joists a smart choice for maximizing open space and performance.
