Fire-Rated Steel Joinery

Fire-rated steel joinery meets the requirements of both public and private buildings. Fire-rated WIŚNIOWSKI doors and walls are made to order and can be adapted to any height and width in projects which obtained a technical approval. Fire-rated steel doors and walls are offered in the following two fire ratings: EI 30 and EI 60, as well as the Sa and S200 smoke control classes.
Fire-rated steel joinery can be used indoors and outdoors for closing rooms such as boiler rooms, back-up facilities, staircases doubling as fire escape in plants, offices, schools, cinemas, hospitals, and in underground passageways, e.g. car parks.

FIRE-RATED PROFILE AND SEAMLESS STEEL JOINERY

A wide range of applications

A SOLID STRUCTURE

Our doors’ reliable operation and unmatched resistance to damage is ensured by a rigid steel structure and welded connections. It is particularly important in the case of frequently used doors that are installed in public buildings.

FIRE PROTECTION

Fire-rated WIŚNIOWSKI doors, windows, and walls provide maximum safety and durability in extreme conditions. They can be manufactured with the following fire ratings: EI 30 and EI 60, in the case of fixed windows also EI120, while maintaining the Sa and S200 class.
