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 column protection up to 600 x 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 steel flange, for SHS/ RHS and PFC beams angles fixed to the wall. Additional angle is fixed to the opposite flange (or face, for SHS/ RHS and PFC) to support flange boards.


Fixings: 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.

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

  • Boards can be left untreated or painted; where decorative finish is required, see Colour/ finish below.
  • Board to board joints on adjacent sides are staggered by a minimum 530 mm.
  • Board thicknesses over 25 mm are installed as a double layer.

Fasteners

Fixing to metal angle: M3.5 CSK Self Tapping Screws.
Fixing to board edge: Chisel point staples minimum 35 x 12 x 1.6 mm (50 x 12 x 1.6 mm for board thicknesses over 15 mm).
Fixing to substrate: Metal angle is fixed directly to the concrete wall with M4 screws into metal plugs, non-combustible concrete anchors or concrete screws (by others).

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.
  • Fixing to substrate: Maximum 300 mm centres. Fixing length to provide a minimum penetration of 30 mm into the substrate.
