We determine the ℓ-modular decomposition matrices of Steinberg's triality groups 3D4(2n) for all primes ℓ ≠ 2 except for some entries in the unipotent characters. As an application, we classify all absolutely irreducible representations of 3D4(2n) in non-defining characteristic up to a certain degree.
