Suspended ceiling system, securing members, and process of installing a suspended ceiling system

A ceiling system comprising:

• a first substrate having a first surface, a second surface opposite the first surface, and a peripheral edge comprising a plurality of sides extending between the first and second surfaces;
• a plurality of securing members attached to the first surface of the first substrate, each of the plurality of securing members comprising:
• a mounting flange having a bottom surface positioned in contact with the first surface of the first substrate and a top surface opposite the bottom surface;
• a positioning member protruding from the top surface of the mounting flange and terminating in a distal edge, the positioning member comprising a first side edge and a second side edge;
• and
• a grid engagement member extending from the distal edge of the positioning member and located centrally between the first and second side edges of the positioning member, wherein any vertical axis that intersects the grid engagement member also intersects the mounting flange;
• and
• wherein each of the plurality of securing members is positioned adjacent to one of the plurality of sides and oriented so that the grid engagement member extends from the positioning member in a direction towards another one of the plurality of sides.

A ceiling system comprising:

• a grid system comprising a plurality of first members arranged parallel to one another;
• a substrate comprising a first surface a second surface opposite the first surface, and a peripheral edge comprising a plurality of sides extending between the first and second surfaces;
• a plurality of securing members coupled to the substrate, each of the plurality of securing members comprising:
• a mounting flange mounted to the first surface of the substrate;
• a positioning member extending from the mounting flange, the positioning member comprising a first surface and a second surface;
• and
• a grid engagement member extending from the positioning member in a direction away from the first surface of the positioning member, the grid engagement member configured to engage one of the plurality of first members to mount the substrate to the grid system;
• and
• wherein each of the plurality of securing members is positioned on the substrate in a same orientation so that the grid engagement members of each of the plurality of securing members extend in a same direction, and each of the plurality of securing members extends from the positioning member towards a same one of the plurality of sides.
