ArcelorMittal's Granite® HFX Cool has been specifically developed for standing seam roofing and facades. It combines:

•    Steel mechanical properties and high ductility performance for on-site assembly
•    Guaranteed performance at low temperatures to enable erection on-site (a great asset in winter conditions)
•    Long life durability and corrosion resistance
•    A wide range of coloured or metallic finishes with satin or matt aspect

This type of covering is highly suitable for the most complex and sophisticated roof shapes and can be used to cover curved, convex, or concave surfaces such as domes, cones, etc., which can also be extended to facades.

The limited number of seams guarantees maximum water tightness - a particular advantage in harsh climatic conditions (mountain or continental climates with considerable exposure to wind, rain, or snow).

Standing seam roofing

A characteristic feature of standing seam roofing and facade is its linear rhythm. Assembled in the workshop or on site from steel strips or coils, this type of roofing combines sophisticated aesthetic appeal with complex shapes and is ideal for both modern and traditional architectural styles.

‘Standing seam’ is a technique that involves joining adjacent steel strips with upturned edges. Folding and interlocking are carried out using traditional methods or special tools. In the cleated seam system, a cap covering the seams ensures that the steel strips are watertight. The cap gives this type of roofing its characteristic look.

This technology is also commonly becoming used for facades. Architectural quality is a priority with this type of roofing. In addition to its state-of-the art technical characteristics, the texture and appearance of the material convey a quality image. The regular pattern of thin lines created by the standing seams complements both traditional and contemporary architectural styles.

Ideal for covering complex shapes, some of the advantages of standing seams are:

•    A sophisticated aesthetic appearance
•    The possibility to combine roofing and facade solutions
•    Limited horizontal joints
•    Durability and stability
•    Maximum air and water tightness
