Following the development trend of green buildings, it is made of low-carbon high-strength steel and environmentally friendly anti-corrosion coatings, complying with green building standards throughout its life cycle and effectively reducing carbon emissions. The lightweight structural design greatly reduces the load of the building main body, and combined with high-efficiency heat and sound insulation auxiliary materials, it can reduce indoor energy loss, suitable for green factories, low-carbon commercial complexes and other scenarios. The quick-assembly modular components eliminate on-site welding, shortening the construction period by more than 50% compared with traditional schemes, with zero construction waste emission, perfectly meeting the requirements of environmentally friendly construction. The components can be 100% recycled and reused in the later stage, balancing the needs of space expansion and ecological responsibility, and is a benchmark choice for modern green building space renovation.
