An important step towards accelerating progress towards carbon neutrality in Spain which will reduce CO2 emissions by 4.8 million tonnes within the next five years. At the heart of the plan is a 2.3 million tonne green hydrogen DRI unit, complemented by a 1.1 million tonne hybrid EAF.
This begins the transition of the Gijón plant from the blast furnace and basic oxygen furnace steel production route to the DRI-EAF production route, which results in a significantly lower carbon footprint. The new DRI will be the first of its kind in Spain and the EAF will be in production by the end of 2025.

SP has been commissioned for the construction of a 10,000 ton CDRI storage facility at the Arcelor Mittal plant in Gjion , Asturie)!!!.
10.000 TON DRI SILO
DOUBLE WALLED SPIRAL SILO
BSP will realized a special type of silo for the storing of the CDRI called “double walled silo”
Flat bottom, 22m diameter – 14m cilinder height, roof 45°angle sloped.
Double wall type consists in a sort of hybrid solution steel/concrete.
BSP erect the first cylinder wall through its special double folding system technology that allow the creation of cylinders profiling and folding rolled steel coils directly on site thanks to special automated former machines.
This hybrid steel/concrete solution, built directly on site using automated profiling technology, ensures high structural strength and natural insulation. It also significantly reduces assembly time, on-site welding operations, and the costly formwork typically required for traditional concrete silos.
LOADING CHUTE STEEL TOWER
To ensure that the product does not get damaged during the descent, a special lattice structure was designed consisting of cups coated with special wear-resistant materials arranged alternately one above the other. The structure will also support the enormous load of the filter and the accessory containers above the roof of the silo.
ERECTION
The silo was assembled on a concrete slab, setting the silo support frame at a height of 8 meters.
The product unloading system, consisting of a 19-meter-high steel column equipped with Hardox-coated wear-resistant buckets, was hung from the roof and raised during the spiral silo construction process. Once the required height was reached, the base segment was mounted to rest on the ground.
This procedure was designed to avoid the use of unnecessary cranes in cramped spaces.
CONCLUSION
The electrification process of furnaces in European steel plants is already underway and is progressing steadily. In this context, BSP is fully integrated into the green economy supply chain and positions itself as a technological partner to the key players driving the ecological transition, actively contributing to the decarbonization of the steel industry.
