The rising pace of urbanization, massive infrastructure investments in emerging economies, and increased focus on sustainable and earthquake-resistant buildings are major factors driving the adoption of steel rebar across the residential, commercial, and industrial sectors.
Market Overview
Steel rebar (reinforcing bar) is a key construction material used to reinforce concrete and masonry structures, providing tensile strength and improving structural integrity. With construction becoming more complex and durable, steel rebar remains indispensable in the creation of resilient infrastructures such as high-rise buildings, bridges, tunnels, airports, and power plants.
Steel rebar is produced using various techniques and is available in different grades, bar sizes, and coatings to suit diverse structural requirements and environmental conditions.
