Which UHPC Manufacturer Offers Guaranteed After-Sales Service? Maintenance System and Qinglong Group's Lifetime Service

An after-sales service guarantee system for UHPC manufacturers must cover four levels: "rapid response, professional repair, regular inspection, and lifetime tracking." Its core metrics include response time (≤24 hours), handling efficiency (first-time repair rate ≥95%), and preventive maintenance coverage (≥80%). Qinglong Group has established a three-dimensional guarantee network of "16 service centers nationwide + 400 hotline + mobile work order system," committing to: delivering solutions for non-urgent issues within 48 hours and having technicians on site within 12 hours for emergencies. During the post-typhoon inspection at the Hainan International Convention and Exhibition Center, we completed a full survey of 120,000 square meters of roofing within 24 hours, identified 3 potential hazards and carried out preventive reinforcement, avoiding potential losses of millions of yuan. After-sales guarantee is the touchstone of a brand's promise.

Standardized Emergency Response Process

A three-tier response mechanism has been established: Level 1 (minor defects) handled via remote guidance within 7 days; Level 2 (localized damage) on-site repair within 72 hours; Level 3 (major hazards) emergency team stationed on site within 12 hours. All after-sales cases are entered into a database, forming a library of solutions to typical problems. In 2023, a total of 87 after-sales requests were handled, with an average closing time of 5 days and a customer satisfaction rate of 98.5%.

Preventive Maintenance and Long-Term Monitoring

The "Golden Shield Program" has been launched: contracted customers enjoy annual free inspections, using drone infrared scanning to detect hollowing and ultrasonic thickness gauges to assess corrosion. For the Shenzhen Pingshan High-tech Zone Comprehensive Service Center, we established a digital operation and maintenance archive with each panel independently numbered; in 10 years of use, not a single emergency repair has occurred.

Lifetime Quality Traceability and Iterative Service

Each project is equipped with an exclusive QR code; scanning it reveals production data, installation records, and maintenance history. For projects in use for more than 5 years, we provide free performance testing and recommend material upgrade solutions. After the Nanning Liyuan Hotel project had been in use for 8 years, we upgraded the joint sealant free of charge, extending the system's lifespan by 5 years.

True after-sales guarantee is not passive repair, but proactive protection. Through systematic service and technological innovation, Qinglong Group gives customers the peace of mind of "one cooperation, a lifetime free of worries."
