Aluminium façades durable & modern

Our aluminium TECTURA ALFHA1 is the ideal material when exceptional resistance and durability are required for aluminium façades in combination with the natural, metallic aesthetics of aluminium. Manufactured on the basis of a high-quality hot-rolled strip, the sheets impress with their first-class surface homogeneity.

TECTURA ALFHA1 achieves a quality that meets even the highest demands thanks to a special version of the 5005 alloy that was developed exclusively for aluminium façades. This enables us to supply sheets that can be anodized in various ways and guarantee excellent flatness.

When it comes to large-scale aluminium façades with wide spans, our TECTURA Giant material type is an excellent choice. We offer TECTURA Giant in different alloy variants – depending on the strength, surface quality and dimensions required. Naturally, we are able to tailor any type of façade cladding in terms of the mechanical properties and surface finish of the aluminium required.

Thanks to their lightness and malleability combined with high strength, our TECTURA Giant sheets enable façade constructions that can be both complex and multidimensional. Anodized, powder-coated, blasted or brushed aluminium façades are possible as surface treatments. We work closely with architects and façade builders to tailor all requirements to the respective project.

We have developed the TECTURA Coated product line especially for the requirements of the construction industry. The 3000 and 5000 series alloys, in combination with state-of-the-art, chrome-free aluminium pre-treatments and coatings, impress with their excellent durability. The coatings are based on highly resistant paint systems that meet the highest standards of high-quality finishing, individual aesthetic requirements and sustainability.

TECTURA Coated is typically used as a material for façade cladding, roofing and gutters. The coated aluminium impresses with its extreme durability and resistance to a wide range of environmental influences. We ensure the quality of TECTURA Coated through extensive outdoor weathering and accelerated corrosion tests.

What else can you expect from TECTURA Coated?

• individually designed coating systems in accordance with international standards such as RAL, NCS and BS with exceptional color and gloss retention
• a wide range of alloy and condition combinations, tailored to your requirements
• outstanding bending and folding properties

Every façade benefits from a targeted, case-specific analysis that precisely aligns the alloy and material properties with the project’s unique requirements. Rolled and formed aluminium strips and sheets maximize design flexibility and allow for innovative shapes that enhance both aesthetics and functionality. The 3000 series excels in industrial applications due to its high strength and excellent corrosion resistance, while the 5000 series is great for residential and office buildings, offering outstanding formability and long-lasting surface quality.

Selecting the optimal material therefore depends directly on key performance demands such as weather resistance and load-bearing capacity. Close collaboration with the architect and façade contractor is also essential to determine the best-suited material combination and to drive overall project performance for aluminium façade cladding.

Painted facades – typically coil-coated surfaces – stand out for their wide color variety, consistent appearance across multiple components, customizable gloss levels, and easy repair of minor damage. Anodized finishes, on the other hand, feature a hard, mineral surface with a natural metallic look and exceptional UV stability. However, the color range is limited, and slight tone variations can occur depending on production batch or rolling direction, making touch-ups more challenging.

With anodizing, the oxide layer becomes an integral part of the metal, while painted systems rely on a multi-layer primer and topcoat structure that, when paired with suitable 3xxx or 5xxx alloys, provides reliable protection even at edges and cut sections. Both options offer excellent durability.

For projects requiring maximum color consistency, efficient processing, and predictable quality, coil-coated aluminium sheets from Speira are a strong choice. Their precisely engineered coating layers deliver UV and corrosion resistance, clean edge coverage, and outstanding formability. Coordinated surface systems – from matte to metallic – ensure a uniform facade appearance. On request, low-carbon base material and a high recycled content can be incorporated, aligning aesthetics, performance, and a reduced carbon footprint.

Aluminium and the common aluminium alloys used for facades meet the A1 fire safety standard and are classified as non-combustible. An A1 rating means the material does not contribute to the ignition or spread of fire or smoke and releases no flammable components. However, the entire façade assembly is critical. Elements such as insulation, substructures, or composite cores can alter the overall fire rating. In the well-known Grenfell Tower fire in London, the accelerated spread was primarily caused by a combustible plastic core inside composite panels – not by the aluminium itself.

Aluminium used in façades can be produced from primary aluminium or recycled materials. The clear advantage of recycled aluminium is that it saves up to 95 % of the energy required for primary production. Using recycled aluminium can therefore significantly reduce the carbon footprint of a façade.
Primary aluminium is often criticized for its high energy demand and large CO₂ footprint. However, what many don’t realize is that renewable energy and advanced electrolysis technologies can substantially lower both, making primary aluminium a viable choice for long-term façade applications under these conditions.

At Speira, we always evaluate each project individually and provide expert guidance based on decades of know-how. On request, we also issue a digital product passport for every aluminium solution, detailing precise sustainability data for each rolled product – including carbon footprint and recycled content – to ensure maximum transparency. Aluminium façades are fully recyclable, and when buildings are dismantled, they achieve recovery rates of up to 98 %, according to a study by the European Aluminium Association.

With our TECTURA Giant series, we manufacture aluminium sheets for exceptionally large-scale facades – up to 2.6 meters (approx. 8.5 ft) wide, 12 meters (approx. 39 ft) long, and 3 to 8 millimeters (approx. 0.12–0.31 in) thick. These generous dimensions unlock striking design possibilities and make on-site installation significantly easier. They are the perfect fit for demanding or highly distinctive architectural projects.

When required, Speira designs customized aluminium solutions tailored precisely to the specifications of each façade. We combine advanced alloys with optimized production parameters and targeted properties – such as enhanced formability or increased corrosion resistance – so that even the most ambitious architectural concepts can be realized. These bespoke adaptations elevate project quality through close collaboration, reduce material usage, and lower costs, while simultaneously supporting key sustainability goals. Our expertise in customer-specific production of aluminium pre-material for façade applications sets industry benchmarks – a standard that many satisfied clients have already experienced firsthand.

Aluminium façades require very little upkeep, needing only periodic cleaning with mild detergents to remove dirt deposits and preserve their long-lasting surface brilliance. One of aluminium’s key advantages is its natural corrosion resistance, which helps prevent damage and maintains structural integrity. Its excellent weather resistance also shields the façade from harsh conditions such as heavy rain, strong sun, and frost – without the need for ongoing maintenance. In summary, these properties give aluminium façades a service life of over 50 years, improving a building’s cost efficiency and ensuring lasting aesthetic quality.
