1. A storage rack system comprising:

  • (a) a storage rack positioned on a substantially horizontal surface, on which an aisle is defined next to the storage rack, the storage rack comprising a support beam and an upright frame supporting the support beam above the substantially horizontal surface, the support beam being formed from a steel channel, which has an outer wall with an uppermost edge and a lowermost edge, an upper flange, and a lower flange, each of said flanges being generally perpendicular to the outer wall, the upper flange extending from the uppermost edge of the outer wall and the lower flange extending from the lowermost edge of the outer wall, the upper flange having an upper, flat, substantially horizontal, load-supporting surface for supporting a pallet load, the outer wall being shaped with a single bend so that the outer wall has an upper portion extending to the uppermost edge and a lower position extending to the lowermost edge, and so that the lower portion defines a generally flat, inclined surface inclined at an angle in a range from about 10°

    to about 80°

    relative to the upper portion so that the upper flange remains generally perpendicular to the upper portion of the outer wall, and so that the lower flange remains generally perpendicular to the lower portion of the outer wall, the flange, converging toward each other, the inclined surface facing toward the aisle and downwardly and being inclined at said angle relative to a vertical plane and constituting a means for deflecting fluids; and

    (b) a fire extinguishing device mounted in the aisle, arranged to discharge a fluid, spaced horizontally from said inclined surface, and located in a fixed position relative to the storage rack, and above the lowermost edge of the outer wall, such that when the fire extinguishing device is discharging a fluid in a direction toward the inclined surface, the discharged fluid impinges upon and is deflected by and below said inclined surface, and said inclined surface deflects the impinging fluid downwardly and inwardly beyond the lowermost edge of the outer wall.
