An Attic Floor Joist Grid System for Weight Bearing Storage called an Attic Grid System. This system features low profile, flat, open and high strength grid panels that are supported by a joist system. The panels install directly onto the ceiling joists in an attic or storage area for residential and commercial applications. The panels are nominal widths that extend essentially to the center points of supporting joists. The system provides a simple and strong support surfaces which only requires simple, easy to use tools for installation. The panels are easily trimmed to size for non-standard operations and for encircling mechanical and electrical objects. The system is “see-through” and permits full air movement. Hence it does not contribute to moisture entrapment, mold and mildew. The materials are fire resistant and do not collapse or emit toxic fumes in the presence of a flame.
