Material
Here’s why TECTURA Giant is the best choice for large, energy-efficient and sustainable buildings.
Product Properties of TECTURA Giant
Giant dimensions - unique benefits
- Strong, weather and corrosion-resistant 5000-series alloys, preferably 5754 or 5083
- Unique range of dimensions available: thickness 3 - 12 mm, width 1650 - 2600 mm, lengths up to 12000 mm; different widths and lengths upon request
- Large sheet dimensions allow cost-effective fabrication of façade elements
- Alloy, temper, mechanical properties and surface conditions are adapted to each project requirement
- Suitable for different surface treatments like powder coating, texturing or anodizing
- Excellent flatness to ensure even appearence
- Protected with UV-resistant PVC foil or laser foil to secure perfect surface quality during fabrication and handling at the construction site
- Possibility to deliver pre-shaped panels (circles, triangles, polygons and more)

Lightweight
Aluminium has one third the density of steel and less than one third the density of copper, making it the ideal material for highrise buildings, as it places a smaller load on the building’s supporting structure. It is easy to install with less required fixations compared to façades made of other metals and the elements can even be partly moved by hand. Additionally, there is the potential to maximize the size of unitized façade elements.
Durable and easy to maintain
Aluminium cladding needs no maintenance and is expected to last the design life of the building (according to BS 5427:2016). Periodic and easy cleaning for aesthetic reasons allows a cost and ecological advantage. Uncoated aluminium will develop a more greyish surface due to weathering and growth of the oxide layer over the years. TECTURA Giant will keep its functionality without any loss of quality even after decades in use.
Energy-efficient
The heat reflection of a bare aluminium surface is about 80–90%, that of a mate surface at around 70% - which means only a small portion of the incoming warmth is absorbed by the aluminium. An aluminium façade limits heating of a building by incoming solar radiation and at same time prevents heat loss from the inside of a building. Aluminium cladding supports insulation, acting as an integral part of a thermal skin. This isn’t just true for new buildings; existing buildings can be made more energy-efficient, too.
Safety
Protection from fire is of utmost importance in any building or residence – no matter the height of the structure.
- TECTURA Giant construction materials are fire resistant.
- Mill-finish or anodized TECTURA Giant products achieve the highest A1 rating in accordance with non-combustibility standards EN 13501, DIN 4102 and 96/603/EC.
- With this rating, TECTURA Giant products can be used on any building at any height without restriction.
- Additionally all of the common means of coating the surface give either full A1 (non-combustible) or A2 – s1, d0 (Limited Contribution to Fire – No Smoke Production – No Flaming Debris) rating and fully meet the building regulations with regard to fire performance.
Handling, Transport and Storage
- Aluminium shall not be contaminated on site through exposure to alkali cement, concrete or similar materials.
- Concrete and plaster works are to be finished before starting aluminium works.
- Protection against any mechanical damage and moisture is required while on construction site.
- Protective foils on the sheet surface applied by Speira can be of great help to maintain excellent surface quality.
Aluminium – sustainable and efficient
Aluminium is part of the solution for more sustainable buildings.
Easy production – endless resources: 8% of the Earth’s crust consists of aluminium.
Good recycling – Aluminium can be recycled infinitely and without quality loss, which dramatically reduces its carbon footprint.
Positive material properties – Aluminium is lightweight, easy to process, corrosion-resistant and safe.
Major design benefits – A clever combination of forming and surface options allows smart façade and roof designs.
