What Is A Metal C Stud?

70mm metal C Stud used for drylining partition wall systems

A metal C Stud is the vertical framing section used within a drylining partition wall. It is installed between floor and head track to create the structural frame of the wall before plasterboard is fixed to either side.

C Studs are commonly used in offices, schools, healthcare buildings, retail units, commercial refurbishments and internal partitioning projects. They are normally paired with a compatible metal U Track to form the base and head of the wall.

Common Metal Stud Sizes Explained

Metal stud sizes are usually selected based on wall height, required wall depth, service zone, insulation requirement and project type. The guidance below is general buying guidance only. Always check the required project specification before ordering.

50mm Metal Stud

50mm metal C Stud is commonly used where a slim partition is required and space is limited. It is often suited to small internal partitions, lightweight room divisions, cupboards, low-height walls and areas where only a shallow service void is needed.

60mm Metal Stud

60mm metal C Stud is a useful step up from 50mm where slightly more depth is needed. It can be used for domestic-style drylining projects, smaller commercial rooms and standard partition walls where a moderate cavity is required.

70mm Metal Stud

70mm metal C Stud is one of the most widely used sizes for commercial partitioning. It provides more depth than smaller studs and is commonly selected for offices, retail units, schools, refurbishments and general contractor-led drylining projects.

92mm Metal Stud

92mm metal C Stud is typically selected for larger commercial partitions, higher walls, projects needing a deeper service void, or specifications that require a more substantial partition build-up.

146mm Metal Stud

146mm metal C Stud is used where a much deeper wall system is required. It is often associated with larger commercial developments, tall partitions, education, healthcare, service-heavy areas and specialist drylining builds.

What Size Metal Stud Should I Choose?

For Residential And Light Internal Partitions

For smaller internal walls where wall depth needs to be kept down, 50mm or 60mm metal studs are often considered.

For Offices, Retail And Commercial Fit Outs

For general commercial partitions, 70mm or 92mm metal studs are commonly selected because they provide a more practical cavity for services, insulation and board build-ups.

For Schools, Healthcare And Larger Commercial Projects

For education, healthcare, public sector and larger refurbishment projects, 92mm and above may be more suitable depending on the required wall height, specification and performance requirements.

For Tall Walls And Specialist Partitions

For taller or more specialist systems, 146mm metal studs, I Studs, Wall Lining Systems or Shaftwall Components may be required.
