Semelia Campbell died in June 2010 when she was caught between the rolling gate and a brick post at the flats where she lived off Maine Road in Moss Side.
Kriston Kearns, of Offerton Road, Hazel Grove, has been charged with unlawfully killing Semelia by gross negligence.
The 40-year-old is the director of Cheshire Gates and Automation Ltd.
He is due to appear at Manchester Magistrates' Court on 12 March.
Semelia had been playing with a friend when she became trapped between the gate and a retaining wall on 28 June 2010.
Her mother Judith Gilroy and the emergency services tried to free her but she went into cardiac arrest.
She was taken to the Royal Manchester Children's Hospital where she died a short time later.
The director of a company which supplied the electric gates in which a six-year-old girl died has been charged with killing her.
