A tread for a steel-pan staircase. The tread includes a lattice structure comprising a top side, a left side, and a right side. The tread further includes a top surface integrally formed on the top side of the lattice structure, a first tongue-and-groove structure disposed on the left side of the lattice structure, and a second tongue-and-groove structure disposed on the right side of the lattice structure. The lattice structure comprises a plurality of lateral members and a plurality of crosswise members. The first tongue-in-groove structure may include a wall descending from the top surface. The second tongue-in-groove structure may include a first wall extending outwardly from the right side of the lattice structure. Extending upwardly from the first wall may be a second wall or a plurality of teeth. The placement of the first and second tongue-in-groove structures may be reversed.

A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so that a user can stand on the deep step and place objects into the attic without having to climb into the attic.
