Finland based Rautaruukki Corporation (Ruukki) specialises in steel and steel construction providing customers with energy-efficient steel solutions for better living, working and moving. Focussing on rapid growth on the Indian market, the company aims to provide special steel products and solutions to Indian and global customers operating in India. Besides a Sales office in Mumbai, Ruukki is also present in India through its partner SteelForce also located in Mumbai.
Currently in India, the company is more focussed on special steels products – Raex wear-resistant and Optim high-strength steels for original equipment manufacturers (OME). Raex is a high-strength, wear-resistent steel with high impact strength. It can prolong the useful life of equipment, reduce wear and improve efficiency. Optim is a high-strength steel with good bankability, forming properties and high quality surface. Both these products find applications in material handling and transport equipment and for booms and other crane parts.
In terms of structural steel for the construction industry – the company has not entered the Indian markets as yet, however in the European market the company is established as steel based construction solutions company. They supply special steel – double grade steel for the framework structures of buildings which not only increase the strength but also the durability of the structures. The steels provided has high tensile strength which means that very little steel is required for actual construction. The energy-efficient building solutions include fully recyclable and reusable life panel, energy panel systems, energy piles & integrated photovoltaic façade system and Solar façade.
Traditionally the building industry believes that heavy is good and the safer one feels. However this notion is changing. For example, in Stockholm, Sweden, a stadium is being built. Considering the Swedish weather, they wanted movable roofs to close the arena during bad climate and open it up on warm sunny days. It had to have retractable roofs and in order to make this work efficiently we used high strength steel tubes. The use of tubes brought down the weight of the structure by 585 tonnes which is 13000 of steel to emissions. Since the weight of the roof went down the rest of the arena could be made simpler using less emissions to transport to the area also.
Similarly for buildings that use piling, we have a solution called energy piles. Ruukki’s energy piles combine the foundations of a building with the collection of ground source heat. Energy piles are particularly suitable for offices, hotels and both single-storey and multi-storey commercial buildings that require both heating and cooling depending on the time of year. Energy piles can be used for all buildings whose foundations are based on piles. The suitability of energy piles for different types of buildings has been assessed by means of analyses, tests and simulations. For example, energy piles can satisfy 71% of the heating needs of single-storey commercial buildings in the form of free heat, as well as up to 100 % of the cooling needs.
The energy pile solution utilises renewable local energy. This improves the environmental efficiency of the property throughout the entire lifespan of the building. In addition to the fact that environmental certification systems take into consideration renewable energy systems in their scoring, they are also important for the users of the building. Environmentally efficient buildings have significantly higher occupancy rates than other buildings in which environmental efficiency has not been prioritised.
Compared with traditional district heating and compressor solutions, the energy pile solution offers 32% lower costs over a period of 25 years, including investment and energy costs. Additionally in comparison with traditional heating and cooling solutions, the investment in a ground source heat solution based on steel piles can be recovered in just five to eight years depending on conditions and alternative forms of heating.
“We believe that India is in a growing phase – economically and as a country. This growth is seen in the infrastructure sector and there are many structures coming up all across the country. As an investment the company is open to enter the market with competitive solutions when the time is right ” said Thomas Hornfeldt, Senior Vice President, Special Steel Sales.
