A grating assembly and a method for manufacturing the same. The grating assembly comprises a plurality of crossbars that are secured together. The grating assembly includes a decorative image that is visible when approaching the grating. The image is formed by providing one or more image sections on one or more of the crossbars of the grating assembly. Each of the crossbars has a front surface and an opposed back surface and the one or more image sections are provided on one or both of the front surface and the back surface.

A portable building is disclosed, having a wall section including a first upwardly extending support member, a second upwardly extending support member and a header supported by the first upwardly extending support member and the second upwardly extending support member, the header having a header channel. The wall section also includes a floor beam secured to the first upwardly extending support member and the second upwardly extending support member, the floor beam having a floor beam channel. Further, the wall section includes a plurality of wall panels, where each of the plurality of wall panels are removably retained within the header channel and the floor beam channel, such that each of the plurality of wall panels are slidable along the floor beam and the header while retained within the header channel and the floor beam channel. Each of the plurality of wall panels are configured to interlockingly engage an immediately adjacent wall panel and an exterior surface of each of the plurality of wall panels form a continuous exterior wall surface.

A beam is an H-shaped steel having flange parts above and under a web part. A through hole is formed on web part to let pipes and the like pass through. A ring beam reinforcing metallic material is disposed through hole. A beam reinforcing metallic material is disposed along the upper and lower flange parts at positions away from the through hole. The beam reinforcing metallic material on the front surface of the web part (opposite side of a flange of the ring beam reinforcing metallic material). The beam reinforcing metallic material in a direction in which a counter-flange surface of the beam reinforcing metallic material faces the flange part. A contacting surface is in contact with web part and is fixed to the web part with a welded section. At this time, the welded section is formed up to the height to which an angle varying part is covered.
