ALHO modular steel construction
Proven, efficient and sustainable
Why bother with outdated construction methods when there is a solution that offers more advantages? Our modular steel construction method is revolutionising construction and outshining conventional methods - and for good reason. For Class 5 buildings with up to seven storeys, ALHO modular steel construction is the future. Anyone who still relies on solid construction today is ignoring the advantages of modular construction, which is not only efficient, but also quiet and clean. There is no way around our modular construction method, especially when it comes to adding storeys, extensions and redensification. With highly variable module sizes, we create buildings that are not only perfectly tailored to requirements, but also to the local conditions. We rely exclusively on quality-tested materials from German brand manufacturers. The result: a pleasant indoor climate, optimum comfort and sustainable quality that makes other construction methods look outdated. We rely on lean production and lean construction - because we cannot afford to waste. Not with resources, not with time and certainly not with quality.
Unfortunately, modular construction still has to contend with numerous prejudices. However, the advantages clearly outweigh conventional construction methods. One major advantage is that the modules are manufactured entirely in our production hall, regardless of the weather. This means that the construction of modular buildings is no longer delayed by adverse weather conditions or cold spells in the winter months. On the contrary: construction projects can progress continuously without construction sites having to be shut down for long periods of time. This not only speeds up the entire construction process considerably, but also reduces the construction time by up to 70 % compared to conventional construction methods. What's more, the precise pre-planning and industrial prefabrication guarantee price and deadline certainty, which is often a challenge in conventional construction projects. All these factors make our modular construction a forward-looking and efficient construction method that offers clear advantages in terms of both time and money.
Steel - the backbone of sustainable construction
Steel is the most recycled material in the world and forms the basis for modular steel construction, which sets new standards in terms of sustainability. While other building materials have to be disposed of at great expense, steel remains a central component of a closed material cycle. 99% of structural steel is reused, 88% of it without any loss of quality. In Germany alone, steel recycling saves over 20 million tonnes of CO₂ every year - a valuable contribution to environmental protection.
Modular steel construction also impresses with its slim cross-sections, which enable impressive space efficiency. In contrast to traditional construction methods, our modular steel construction offers a high degree of flexibility in the design and utilisation of buildings. Thanks to the self-supporting steel skeleton construction with non-load-bearing walls, modular buildings can be easily expanded, extended or repurposed. Dismantling and recycling are just as straightforward and promote the sustainable use of resources.
But it gets even better: by using green steel, we can reduce CO₂ emissions in the production of modular buildings by a further 30 %.
In traditional steel production, iron ore is heated in energy-intensive blast furnaces to obtain pure iron for steel production. A chemical reaction releases a lot of CO₂ in the process. Around 75% of steel is still produced in this way. However, the goals of the Paris Climate Agreement place limits on this process: The aim is to completely switch steel production to green steel by 2050. The key to producing green steel lies in using up to 100% scrap as a raw material and utilising an electric arc furnace instead of a blast furnace. In this way, steel can be produced without fossil fuels and without natural gas as a reducing agent, and a further 30% of CO₂ equivalents can be saved during the construction of a building.
ALHO is cooperating with Klöckner & Co SE, a leading steel and metal distributor, to ensure transparency and security in the procurement of environmentally friendly steel. As a pioneer in climate protection, Klöckner has developed the Nexigen® brand, which offers CO₂-reduced material and logistics solutions to help customers build sustainable supply chains. With this progressive development, climate-neutral steel module construction is well on its way from vision to reality.
