Description

E04C covers structural elements and building materials used in construction, including beams, columns, panels, frames, and other load-bearing or non-load-bearing components. This subclass encompasses both traditional materials (wood, stone, concrete, steel) and modern composite or prefabricated elements, as well as their manufacturing processes and assembly methods. Inventions relating to structural improvements, material compositions, reinforcement techniques, and connections between building components are classified here. Related specific construction technologies (such as roofing, insulation, or finishing) may fall under other E04 subclasses, while E04C focuses primarily on the primary structural framework and constituent materials.
