We do offer solutions for fire‑protecting structural steel beams and columns through the Promat product range. To specify an appropriate system, three key pieces of information are required:

• The required fire protection period (e.g. 30, 60, 90, 120 minutes).
• The steel section shape and size, used to determine the Hp/A (A/V) value.
• The number of exposed sides and whether the steel member is a beam or a column, as these directly influence the heated perimeter and therefore the required protection thickness.
• The limiting steel temperature for the structural design

The steel dimensions, number of exposed sides, and element type (beam or column) are used to calculate the Hp/A (A/V) value—known as the section factor. The section factor is the heated perimeter (Hp) divided by the steel cross‑sectional area (A). This value is then used to determine the required level of protection by referencing the appropriate Promat tables for each fire‑resistance period.

Promat provides a range of frameless board systems for protecting structural steel, offering faster installation and reduced space requirements. These systems can be reviewed individually for detailed performance characteristics.

PROMATECT®‑XS – Frameless EN‑tested System - Up to 60 Minutes Protection
A1 non-combustible calcium silicate board (EN 13501‑1) designed specifically for the fire protection of structural steel up to 600 mm deep, providing up to 60 minutes of fire resistance when installed as part of a tested system. It has been tested to EN standards, including bespoke junction testing carried out collaboratively by Siniat and Promat, ensuring valid performance at interfaces between steel encasements and partitions.
