In this work, we study the disorder effect on topological metals that supporta pair of helical edge modes deeply embedded inside the gapless bulk states.Strikingly, we predict that a quantum spin Hall (QSH) phase can be obtainedfrom such topological metals without opening a global band gap. To be specific,disorder can lead to a pair of robust helical edge states which is protected byan emergent $Z_2$ topological invariant, giving rise to a quantized conductanceplateau in transport measurements. These results are instructive for solvingpuzzles in {various transport experiments on QSH materials} that areintrinsically metallic. This work also will inspire experimental realization ofthe QSH effect in disordered topological metals.
