Support beam cutting techniques primarily include disc cutting and diamond wire cutting. Diamond wire cutting offers fast speed, high flexibility, and low construction noise. It is increasingly applied in building renovation projects. Disc cutting breaks away from the traditional methods of gas cutting or directional blasting after jackhammer removal, and the Inner Mongolia support beam cutting project uses diamond particle-coated cutting discs for cutting, resulting in clean, straight切口 without the need for post-processing. It is not restricted by construction site conditions, environmental protection, project timeline, or safety concerns, and is applied in the structural renovations and cutting construction of various large buildings.
