70mm Metal I Stud 4200mm

Product Overview

70mm Metal I Stud for internal partition systems, used with I Track to build acoustic, fire-rated, and medium-performance walls.

With wider flanges and integrated service slots, it provides extra rigidity and simplified routing of services, setting it apart from standard C Studs.

Installed as vertical studs in non-loadbearing partitions, the stud offers a consistent fixing edge for plasterboard linings, suitable for offices, classrooms, and other non-loadbearing internal wall applications.

The 70mm cavity provides depth for thicker insulation and larger service routes, which can support enhanced acoustic and fire performance when used as part of a tested system. Its geometry improves resistance to twisting during handling and installation, supporting precise alignment throughout the wall height.

Designed for use with 70mm head and base tracks and compatible with standard deflection head details, the stud accommodates single- or multi-layer board linings as required by the chosen and tested wall system.

Manufactured from galvanised steel, it ensures strength, durability, and corrosion resistance for reliable long-term performance in typical interior environments.

Supplied in a 4200mm length for use in tall wall constructions where extended stud length is required.

Features & Benefits

• Rigidity under load: I-profile delivers higher in-plane rigidity than 70mm C studs, helping achieve flatter finishes and reduced deflection when boards are installed.
• Increased cavity depth: 70mm cavity accommodates thicker insulation and larger services than 50mm systems.
• Accurate finishing: Straight roll-formed edges support true board alignment and smooth jointing.
• System compatibility: Aligns with standard 70mm tracks, head deflection details, and common board fixing patterns.
• Durable material: Galvanised steel resists corrosion for a consistent service life in dry internal applications.
• 4200mm length: Helps maintain alignment and rigidity across extended wall heights.

Applications

• General internal partitions: Provides reliable framing for non-loadbearing walls in offices, classrooms, and similar spaces.
• System-tested corridor partitions: Can be used in corridor walls when specified as part of a tested and certified wall system.
• Services integration: Offers cavity depth for routing pipework, conduits, and cable bundles.
• Acoustic improvements: Supports sound reduction when combined with insulation and appropriate board layers in accordance with system test data.

Installation Guidance

• Set-out: Fix compatible 70mm head and base tracks to the substrate per system guidance.
• Stud placement: Insert studs into tracks at the spacings specified by the lining system and project design.
• Openings: Reinforce doorways and penetrations with appropriate studs and trimmers as detailed by the system.
• Board fixing: Attach plasterboard to stud faces using approved drywall screws and patterns.
• Services & insulation: Install services and insulation within the cavity without overcutting or distorting studs.

Compliance & Performance

• Material specification: Manufactured from galvanised steel suitable for interior drywall applications.
• System role: Non-loadbearing vertical framing for plasterboard partitions; performance determined by the tested system build-up.
• Acoustic & fire ratings: Dependent on board type, layers, stud spacing, and insulation; follow the relevant system data.
• Important note: Edges may be sharp - use gloves and eye protection; do not use as a structural loadbearing member.
