Ever wondered how strong steel really is? We put a 32mm steel rebar to the ultimate test: pulling it from both ends until it breaks. This bar withstood a massive 570 kilonewtons of tension — that’s about 58 tons of pulling force — before it finally snapped. This value is called its Ultimate Tensile Strength, the max stress steel can resist before failing. This is the science behind what holds bridges, towers, and skyscrapers together. Real strength, measured and tested. ➡️ Follow @civilext_ for
