Steel Horse is a motorcycle manufacturer in the HD Universe.
As a brand name, Steel Horse doesn't appear on it's motorcycles, but the police on the police radio will refer to a motorcycle as one. The only known vehicle made by Steel Horse is the Zombie, however the Hexer has both manuals and a poster with Steel Horse branding in Grand Theft Auto V. Judging by its name, Steel Horse could be based on American IronHorse, as well as a play on the fact that Steel Horse is an old slang term for motorcycles used by biker gangs.
While there are no controllable Steel Horse vehicles in GTA V, the office of Beeker's Garage in Paleto Bay, Blaine County features a manual for a Steel Horse featuring Steel Horse logos, and a similar poster.
As the Hexer in-game is a custom bike made by the chop shop Liberty City Cycles, it is possible that the standard Hexer is manufactured by Steel Horse, since it's seen on the front of a Hexer owners manual (see gallery). In addition, an unused police scanner audio file named "0x19E7442A" mentions the manufacturer by name.
