Aluminium and steel fire-rated structures

We manufacture type-approved aluminium and steel fire-rated assemblies such as glazed walls and windows for fire classes E30, EI30 and EI60. With local approval, we have produced glazed structures up to fire-resistance class EI90. Visually, these fire-rated solutions do not differ from standard window and façade systems. As the name suggests, they are designed to withstand fire significantly better than conventional structures and to slow the spread of flames.
