Style, strength, resistance and zero maintenance. METRA Building aluminium shutters are available in many finishes and unlimited colours, able to enhance both the façade and the living space.
Also available in the “folding” or “adjustable” version, they are the ideal choice for different architectural solutions – new buildings, conservative restorations, renovations – even in cases where strict environmental regulations must be respected.
Weatherproof, METRA Building aluminium shutters and blinds guarantee maximum water tightness, excellent resistance to air, salt and aggressive atmospheric agents.

Aluminium accessories complete the shutters: sturdy hinges support the shutter, enhancing its aesthetics, the hinges are “concealed” and the bolts are reinforced. All this to ensure maximum comfort together with the handle or sliding mechanisms and the different openings designed to guarantee ergonomic grips.
The METRA Building aluminium sliding shutter can be oversized compared to the normal window and can become the multi-track system of a large curtain wall or sliding wall.

Origins Line

The shutters of the Origins line are available in multiple solutions with fixed or adjustable blades to meet the needs of total or partial darkening of rooms, protecting against external glances while combining ease of maintenance and sturdiness. In addition, thanks to the complete range of models, the Origins line allows for numerous applications, satisfying the aesthetic needs of historic centres and new buildings.

When designing a building, it is of utmost importance to determine the level of natural light. Sunshades are architectural elements designed to provide shade and regulate the entry of sunlight into a building or outdoor space. This METRA Building system is available in a variety of designs. Sunshades not only add a unique and distinctive character to architectural designs, but also integrate perfectly with window frames or curtain walls.

The possible automated management of blade rotation to regulate irradiation, through a home automation system, adds further value to the system. They represent an innovative solution that combines the eco-sustainable essence of aluminium with the possibility of harmoniously integrating photovoltaic panels into the blades to generate clean energy with reduced environmental impact.
