When talking about Industrialized Construction (IC), we primarily are focused on the former, CFS framing, as this type of construction results in members that can be easily cut and shaped to specific project needs and are light enough for easy transportation from factories to project sites. The unit floors above are then framed out with cold-formed steel and make up the tower.The ground floor podium is framed out with structural steel to accommodate the large open areas that are on the ground floor for amenity space.For typical apartment projects, both CFS and Structural Steel can be used to your advantage. It is very common to have CFS and Structural Steel framing on the same project. This is what most people envision when they hear “steel framing”. Because it is thicker and heavier than light gauge steel, the best fastening methods employ welding, bolting, or riveting. Used in conjunction with concrete, the most durable structures employ structural steel. Structural steel projects are framed out with heavy, large members and used for framing out large open spaces and buildings, bridges, and industrial sites. “Hot-rolled” means the member is shaped while the steel is molten hot. Structural Steel is hot rolled, much thicker, and considerably stronger and heavier.
In general, light gauge will produce less waste, which is more environmentally friendly and cost-effective than wood alternatives. Due to their strength, light gauge steel also requires fewer studs because they can be placed further apart. These thin members are used to frame out walls, floors, and roof systems in much the same way as 2x wood studs. These light-framed steel members are similar to wood-framed construction in principle.
How to price cold formed steel framing series#
“Cold-Formed” means the sections are shaped at room temperature by guiding the steel through a series of rollers.
Generally, the depth of cold-formed individual framing members range from 2 to 12 inches (50 to 300mm) and the thickness of material ranges from 0.035 to about ¼ inches (0.90 to 6. The term “Steel” is one of those broad terms that gets thrown around a lot. cold-formed steel are corrugated steel roof and floor decks, steel wall panels, storage. The provisions of this section shall control the construction of exterior cold-formed steel wall framing and interior load-bearing cold-formed steel wall framing for buildings not more than 60 feet (18 288 mm) long perpendicular to the joist or truss span, not more than 40 feet (12 192 mm) wide parallel to the joist or truss span, and less than or equal to three stories above grade plane. With lumber prices soaring, developers are looking for steel solutions. Larry has more than 35 years of experience in management, marketing and strategic communications, including 25 years in the steel and construction markets.We’ve recently discussed cold-formed steel and how it can be utilized with Industrialized Construction. The SFIA’s 1,200 members come from virtually every facet of the construction industry, including steel mills, coil coaters, stud and connector manufacturers, component fabricators, engineers, researchers, suppliers/distributors and builders and framing contractors.
Larry Williams is the Executive Director of the Steel Framing Industry Association, the industry organization dedicated to expanding the market for cold-formed steel through promotion, advocacy, education and by providing a positive environment for innovation. Other activities includes serving as the Vice Chair on the Chicago Committee on High Rise Buildings. Now Bob is the Program General Manager for the Steel Framing Industry Association as well as the Director of Technical Services for the Association of Wall and Ceiling Industry. During his time at USG, he has held various technical and management positions, including product and system design and technical consultation to the AEC community.
