GGG 70 steel grade is specifically designed for applications in the construction sector that require high strength, durability, and sustainability. The mechanical properties ensure exceptional load-bearing capacity, resistance to deformation, and the ability to withstand harsh environments. The high tensile and yield strength, along with the excellent elongation and impact strength, make it suitable for structural components, such as beams, columns, and frames.

The chemical composition of GGG 70 steel grade is carefully formulated to enhance its mechanical properties and provide corrosion resistance. The carbon content provides the necessary strength, while the silicon contributes to increased hardness and wear resistance. The presence of other alloying elements, such as manganese, chromium, copper, nickel, molybdenum, magnesium, and titanium, further improves the steel’s strength, toughness, and resistance to corrosion.

By empowering sustainable solutions in the construction sector, GGG 70 steel grade promotes long-lasting and eco-friendly infrastructure. Its high durability reduces the need for frequent repairs or replacements, minimizing waste generation and resource consumption. Additionally, the corrosion resistance of the steel extends the lifespan of structures, reducing the environmental impact associated with maintenance and renovation.

Overall, GGG 70 steel grade offers a reliable and sustainable solution for various construction applications, contributing to the development of environmentally friendly and resilient infrastructure.
