Structural frame materials

Abstract

This article is a structural frame material used as a framework when assembling structures such as safety fences, partitions, and frames installed around industrial machinery. When in use, this article is cut to the length appropriate for the structure being assembled and assembled vertically and horizontally using mounting fixtures such as brackets, as shown in the "Reference Diagram Showing Usage". The inner surface of the deep groove provided along the longitudinal direction on the side of this article is provided with grooves and protrusions into which the threaded portion of bolts used to fix brackets can be directly screwed. As shown in "Reference Diagram 2 Showing Usage", the legs protruding from the bottom surface of the bracket are fitted into the recesses located on both sides of the deep groove. This fitting prevents the bracket from rotating and the bolts and brackets from falling out of this article.
