One of the largest sections in every registry and the noisiest: developers register a company per project (SPE/SPV), so division 41 overstates the number of operating builders. Division 43 (specialised trades) is where the actual contractors are. Construction-tech, building-materials distributors, equipment rental and fintech lenders use this section with a size or age filter.
