A building panel of the type having a planar central portion with a riser and locking member provided at each of two opposed edges of the central portion and which are adapted to connect in interlocking fashion with a locking member provided along an edge of an adjacent building panel of similar structure. Each locking member is provided in the form of a channel-shaped locking member connected to a substantially vertical riser by a portion of the panel extending at an angle relative to the riser. One locking member is connected to a riser by a portion extending inwardly relative to the panel and the other locking member is connected to a riser by a portion extending outwardly relative to the riser thereby providing for a concentric connection of each locking member with a locking member of an adjacent panel with the connection being concentric and substantially centered over the risers. A plurality of deep-set longitudinally extending ribs are provided in the central portion of the panel which together with the concentric, oversized locking members provides a rigid panel capable of extending over a substantial span length.
