Application

Steelwork protection.

Description

PROMAT PROMATECT®-250 is a non-combustible mineral bound light weight board and provides a high degree of strength and dimensional stability and fire protection to structural steel and is suitable for areas where the relative humidity is up to 85%.

It is classified A1 non-combustible according to BS EN 13501-1.

Features and benefits:

Three-sided beam protection up to 600 mm.
Angle fix.
PROMATECT®-250 comprises autoclaved calcium silicate spheres (PROMAXON® is a synthetic hydrated calcium silicate in spherical form) bound in a mineral matrix.
Off-white in colour.
One face is smooth and ready to form a finished surface, able to receive almost any form of architectural/finish treatment.
The reverse face is sanded.

Specification data - Rigid sheet casing systems

Support	Metal angle 50 x 25 x 0.5 mm. Fixings: 3.7 x 16 mm shot-fire nails or M4.2 x 12 mm wafer head screws. Guidance for specification option: Casings are installed using metal angles fixed to the underside of the top steel flange for I-beams, for SHS/ RHS/ CHS and PFC beams angles fixed to the soffit. For widths over 325 mm, an additional Z-section is fitted to the underside of the bottom face of the steel, at maximum 610 mm centres, to support the soffit boards. Fixings: maximum 300 mm centres, for I-beams. Manufacturer guidance For beam widths over 325 mm, use minimum 25 x 25 x 1.2 mm Z-sections at maximum 610 mm centres to support soffit boards, fixed with 3.7 x 16 mm shot-fire nails or M4 x 9.5 mm pan head screws at maximum 300 mm centres.
Insulation	Low density (10–30 kg/m³) glass mineral wool. Guidance for specification option: If required for acoustic or thermal performance. Not required.
Linings	Inner and outer layers: PROMATECT®-250 board thickness determined by section factor (A/V), fire resistance period and limiting steel temperature. Maximum board length 1250 mm. Guidance for specification option: Minimum PROMAT PROMATECT®-250 thickness for compartmentation either side of steel: 60 minutes: 15 mm; 90 minutes: 20 mm; 120 minutes: 25 mm. Where protection to the structural steel and compartmentation are required, thicker of the two boards should be used. Manufacturer guidance For double layer encasements joints between layers must be staggered by minimum 530 mm, no cover strips are required to inner layer. Boards can be left untreated or painted; where decorative finish is required, see Colour/ finish below. Board thicknesses over 25 mm are installed as a double layer, board joints between layers staggered by 530 mm minimum. Where more than one layer of board is used in a casing, the thicker layer should be applied first.
Fasteners	Fixing to metal angle: M3.5 CSK Self Tapping Screws. Fixing to board edge and coverstrips: Chisel point staples minimum 35 x 12 x 1.6 mm (50 x 12 x 1.6 mm for board thicknesses over 15 mm). Guidance for specification option: Fixing to metal angle: Maximum 200 mm centres. Screw length to provide minimum penetration of 10 mm through the angle. Fixing to board edge and coverstrips: Maximum 150 mm centres. End staples are located nominally 40 mm from the corner of the board.
System accessories	FSi Promat Pyrocoustic® Fire Resistant Sealant.

Fire resistance	Guidance for specification option: Fire resistance (minutes) to EN 13501-2. Insert requirements.
Colour/ Finish	Guidance for specification option: Insert requirements. Manufacturer guidance Decorative finishes should be applied in accordance with Promat Technical Data Sheet TDS 056 (https://www.promat.com/en-gb/construction/documentation/).
Section factor	Maximum 350 m-1.
Steel sections	600 mm deep and 325 mm wide (maximum).
Substrate	- Manufacturer guidance For SHS/ RHS/ CHS and PFC beams, where it is not possible to fix to the underside of the flange, metal angle is fixed directly to the concrete soffit with M4 screws into metal plugs, non-combustible concrete anchors or concrete screws (by others) at maximum 300 mm centres. Fixing length to provide a minimum penetration of 30 mm into the substrate.
Strips	Coverstrips: Thickest encasement board layer x 100 mm wide PROMAT PROMATECT®-250 coverstrips fitted behind board joints and at the start and end of the beam. Guidance for specification option: Coverstrips are not required to the bottom flanges of beam encasements.
Third-party certification	As detailed in UL-EU Certificate No. UL-EU-01220a-CPR.
