Modern roofing and flooring systems rely heavily on steel joists and joist girders. Steel joists and joist girders are an efficient, cost-effective alternative that can significantly increase the value of your construction, whether you’re creating a single or multistory building.
For a roof or floor system, joist girders act as the main framework components and support concentrated loads with short spans. Standard steel joists, which in turn support the steel roof or floor deck, are frequently part of these focused loads. A number of economic and performance benefits are introduced by the open-web design of steel joists and joist girders, including less project weight, easier and quicker assembly, and seamless integration of mechanical, electrical, and plumbing (MEP) systems.
These advantages both individually and collectively save time and money. With composite joists and deck, many of these advantages are also achievable in multi-story construction situations.
The Global Steel joist girders market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The rapid technical improvements in production techniques and material combinations, along with the robust recovery of the global construction sector, are anticipated to be some of the key drivers of the market for girders during the forecast period. The market for girders is also expected to expand as a result of the improved qualities of the majority of contemporary girders, including increased ductility, seismic resistance, strength, and ease of manufacture.
The need for girders is anticipated to increase because of the global trend toward smart cities. The introduction of numerous cheap housing projects around the world, rapid population expansion, and ever-increasing urbanisation are all predicted to support the growth of the girders market.
The market for girders is expected to rise as more people become aware of the benefits of modern girders, including their increased energy efficiency, ease of project completion through the use of girder channels and beams, and improved flexibility.
Vulcraft can design and manufacture specialty joists such as gable joists and barrel joists to assist architects and engineers in realising their vision. These joists can be as much of an architectural asset to the structure as they are a significant structural component.
K-Series joists are most commonly used in roof design and are designed for use with lighter loads. K-Series joists are typically used in situations where shorter span conditions are required. KCS-Series Joists are a variant of the K-series joists that are designed for constant shear and moment, allowing for greater flexibility in locating extra loads such as those from rooftop units.
LH-Series Joists are designed for longer spans and can support heavier loads. Special profiles for a variety of conditions are possible with these joists. Gable joists and arched joists are two common special profiles.
DLH-Series (Deep Longspan) joists, like LH-Series joists, are designed for longer span conditions and can support heavier loads. DLH joists, which have standardised depths ranging from 52″ to 120″ and spans up to 240 feet, also allow for special profiles to accommodate a variety of conditions.
The Composite Joist system, also known as the CJ-Series, is an open web system in which the concrete slab serves as the composite top chord of the underlying steel joists. Welding steel shear studs through the steel deck to the steel joist top chord transfers shear from the concrete slab to the underlying steel joists. Each joist is designed with a sufficient number of steel shear studs to develop the bottom chord’s yield strength. When compared to conventional steel joist systems, the CJ-Series has a stiffer response to applied loads.
Their Ecospan Structural Floor System, which uses a Shearflex Fastener instead of a welded shear stud, is another option that uses composite joists. The heat-treated self-tapping, self-drilling Shearflex fastener not only attaches the deck to the joists but also acts as a shear connector between the steel and the concrete.
Joist girders are the most important framing members. The span is simple, with open web steel joists supporting equally spaced concentrated loads. Joist girders are intended to maximise the use of steel in longer spans for primary framing members.
