Aircraft Belts of Kemah, Texas, long a provider of aircraft occupant restraint systems, is branching into the corporate aircraft decorative plating business with the opening of subsidiary Signature Plating. The new company will occupy a 12,500-sq-ft facility in Cibolo, Texas, near San Antonio. A spokesman said Signature Plating, scheduled to open in June, will specialize in a wide variety of plating processes for corporate aircraft cabin metal accessories. Lawrence Donoho has been selected to serve as president of the new company.
