How Does the Overall Cost of UHPC Exterior Walls Compare to Stone Exterior Walls? Whole Life Cycle Cost-Effectiveness Analysis

The overall cost of UHPC exterior walls (including materials, fabrication, installation, and maintenance) is 30%-50% lower than that of stone exterior walls, and the 20-year life-cycle cost is 50%-70% lower. Backed by large-scale production and integrated services, Qinglong further amplifies this cost-performance advantage: projects such as the Dongting Lake Museum and the Yangshengtang Pharmaceutical Industrial Park have all been delivered with "low cost and high texture quality".

I. Initial Cost Comparison: UHPC Has Significant Advantages

The gaps in initial investment lie across multiple stages. Material cost: UHPC is priced at about RMB 200-400/㎡, while natural granite costs RMB 400-800/㎡; Qinglong's bulk procurement makes its UHPC material cost 10% lower than the industry average. Fabrication cost: UHPC is precast in the factory at a fabrication fee of RMB 60-100/㎡, while stone requires on-site cutting and polishing at RMB 100-150/㎡; Qinglong's automated production lines cut fabrication costs by 20%. Transportation and installation: UHPC has a bulk density of 2400-2600kg/m³, only 1/2 that of stone, so transportation costs are 30% lower; installation requires no heavy equipment, cutting labor costs by 40%, and Qinglong's nationwide logistics network further compresses transportation costs.

II. Life-Cycle Cost: UHPC Saves More in the Long Run

The maintenance cost gap keeps widening over the years. Cleaning cost: UHPC is cleaned once a year at RMB 6-10/㎡, while stone is cleaned twice a year at RMB 10-15/㎡; Qinglong's UHPC self-cleaning surface reduces cleaning frequency. Repair cost: repairing damaged UHPC costs RMB 30-60/㎡, while repairing cracked stone costs RMB 150-250/㎡; Qinglong's special repair agent produces minimal color difference for a natural finish. Replacement cost: UHPC lasts more than 30 years versus 15-20 years for stone, and Qinglong's UHPC replacement cost is only 1/3 that of stone. Protection cost: UHPC needs protective treatment once every 5 years at RMB 30-40/㎡, while stone needs it once every 3 years at RMB 60-80/㎡, and Qinglong's protective agent offers stronger weather resistance.

III. Qinglong's Cost Optimization and Project Practices

Full-process control delivers a cost-performance win-win. Integrated services: design + production + installation + maintenance are seamlessly connected, reducing intermediate steps; Qinglong's integrated services cut total project costs by 15%. Mold reuse: a library of over 1,000 standard-shape molds saves 40% on custom mold costs; Qinglong reused molds on the Yangshengtang Pharmaceutical project, shortening the construction period by 5 days. Project cases: the 8,800㎡ UHPC stone-look curtain wall of the Dongting Lake Museum had an initial cost 40% lower than stone, saving over RMB 2 million in 20-year life-cycle costs; the 3,000㎡ UHPC exterior wall of the Shenzhen Yirui Biotech Building cost only 60% of stone with greater design freedom, earning high recognition from the owner.
