4 Hour Fire Rated Steel Stud Partition

Where longer fire resistance is required for compartment walls, a steel stud partition provides a practical solution while maintaining a lightweight construction suitable for a wide range of building projects.

The 4 Hour Fire Rated Steel Stud Partition supplied by PROSAFE, based on the selected design, is constructed using two layers of 9mm PROMINA®-60 board fixed to both sides of a steel stud framework with mineral wool insulation installed within the cavity. When installed in accordance with the tested construction, the complete assembly has a system thickness of 136mm.

Tested to BS 476 Part 22:1987 for non-loadbearing construction, the system provides 240 minutes of fire resistance from both sides and achieves a Fire Resistance Level (FRL) of -/240/240 when installed as the approved tested assembly.

Suitable for commercial, industrial, institutional and residential developments, this partition system provides a dependable solution where extended fire compartmentation is required.

Provides up to 240 minutes of fire resistance from both sides.
Tested to BS 476 Part 22:1987 for non-loadbearing construction.
Double-layer board construction for enhanced fire performance.
Lightweight partition system for efficient installation.
Time and cost effective construction solution.
Offers thermal resistance and impact resistance.
Suitable for both new construction and refurbishment projects.
Built using PROMINA®-60 fire resistant boards.

This system is designed as a non-loadbearing steel stud partition.
The tested assembly has a system thickness of 136mm.
Where the partition height exceeds 4000mm, consult PROSAFE for the appropriate steel channel sizes.
Perimeter gaps between the boards and surrounding masonry should be sealed using PROMASEAL® Acrylic Sealant to achieve the required fire resistance and acoustic performance.
The complete system, including the steel framing, PROMINA®-60 boards, mineral wool insulation and associated components, should be installed in accordance with the approved tested assembly.
Refer to the PROMAT technical handbook and system drawings for complete installation requirements.

Frequently Asked Questions

Is this system tested?

Yes. This system has been tested to BS 476 Part 22:1987 for non-loadbearing construction and provides 240 minutes of fire resistance when installed in accordance with the tested assembly. It is supported by the relevant test documentation and is accepted for BOMBA submission where applicable.

Do fire rated systems require certificate renewal?

No. Building owners do not need to renew the fire test certification. The certification is maintained by the system manufacturer (PROMAT), while the installed system should always follow the tested assembly and manufacturer recommendations.

How much does this system cost?

The cost depends on factors such as the project size, partition dimensions and specification requirements. Contact PROSAFE for a project-specific quotation and technical advice here.

Why choose PROSAFE for passive fire protection systems?

PROSAFE supplies PROMAT fire rated systems that are rigid, lightweight, moisture resistant and supported by tested documentation. With a wide range of system options and practical technical support, we help make system selection easier for projects across Malaysia.

Can this partition be installed above 4 metres in height?

Yes. However, where the partition height exceeds 4000mm, the size of the steel channels should be determined in accordance with PROMAT recommendations. Contact PROSAFE for project-specific technical advice here.

Which side of the partition provides fire protection?

This system provides 240 minutes of fire resistance from both sides when installed in accordance with the approved tested assembly.
