1. What is Cold-Formed Steel (CFS) Framing?

Cold-formed steel framing, alternatively referred to as light gauge steel (LGS) framing or cold-formed steel truss, refers to thin steel that has been rolled by cold-working processes to form shapes without being reheated.

2. Advantages and applications of cold-formed steel truss framing

CFS trusses offer significant advantages for mid-rise, multi story and multi-family projects.

Mid-rise and multi-family structures come with unique challenges and considerations. They are high-traffic, high-usage, and often, high-turnover environments. They are more prone to wear and tear, so they need to be durable, comfortable, and visually appealing to attract and retain tenants while remaining profitable for owners.

CFS trusses address these considerations thanks to some outstanding points:

– Lightweight: lighter loading on buildings than other traditional construction materials.

– Capable of long-spans: easily contribute to larger floor areas and taller buildings because of lightweight material.

– Diverse in configuration: can be formed into diverse desired shapes: C section, U section, hat channel…

– Efficient and cost-saving: simple installation leads to reducing on-site labor cost and material waste.

Cold-formed steel framing in mid-rise construction

Cold-forming steel truss framing is also popular in constructions with sloped roofs and challenging conditions.

They outperform other framing materials for various roof profiles:

+ Pitched roofs, flat roofs

+ Cantilevers and overhangs

+ Vaulted ceilings and curved roofs…

3. Some typical types of cold-formed steel truss sections

C truss/C stud/C section

It refers to cold-formed steel that has been formed into a C-shape with a lip return. These are commonly used as a vertical part in wall or column framing. Deeper sections can also serve as floor joists, roof joists, or beams.

Hat channel/Top hat/Batten

Hat channels, also known as battens or top hats, are used to provide a fixing point for roofing materials such as shingles or tiles.

Generally, C truss/C section and batten are the perfect couple for a great roof structure, especially lightweight structure.

U track

U Track is also a type of cold-formed steel. U track is often used as the horizontal framework of stud partitions, in conjunction with vertical metal studs (C studs). This combination is commonly employed in concealed grid gypsum ceilings for lightweight structure.
