Abstract
A support beam for a storage rack has a tubular profile, which defines a ledge opening upwardly and inwardly, and which defines a generally flat, indicia-receiving surface facing outwardly and either downwardly or upwardly at an angle from about 20.degree. to about 70.degree. relative to a vertical plane. Alternatively, the tubular profile may define two such surfaces defining an obtuse angle relative to each other, namely an upper surface at an angle from about 20.degree. to about 45.degree. relative thereto and a lower surface at an angle from about 45.degree. to about 70.degree. relative thereto, or a generally arcuate, indicia-receiving surface having a suitable measurement. The indicia-receiving surface enables a person who is standing, or who is sitting on a lift truck, to have a generally perpendicular line of sight to such surface. The support beam may also be used in combination with a properly positioned fire extinguishing device to extinguish a fire in a supported load. When the fire extinguisher is activated, the fluid that is discharged impinges off the indicia-receiving surface, which may be inclined or curved, and onto the load.
