How Is the After-Sales Service of GRC Manufacturers? Qinglong Group's 28-Year Full-Cycle Service System and Customer Value Assurance

The after-sales service of a GRC manufacturer is a key indicator for measuring a company's comprehensive strength and long-term partnership value, directly affecting the long-term stable operation of a project after completion and the owner's return on investment. As a group that has specialized in the GRC field for 28 years, Qinglong Group has built a three-dimensional after-sales service system of "preventive maintenance + rapid response + lifetime tracking," achieving one-stop service assurance through a nationwide network of service stations, a 7×24-hour technical support hotline, and a digital operation and maintenance platform—with responses within 2 hours, solutions provided within 24 hours, and personnel on-site within 48 hours for major issues. In national-level landmark projects such as the Wuhan Han Show Theatre and the Hainan International Convention and Exhibition Center, Qinglong's after-sales team has ensured through regular inspections, professional cleaning, and localized repairs that projects maintain over 95% of their performance indicators even after more than 10 years of operation, truly embodying the value philosophy that "delivery is not the end; service has just begun."

The core of after-sales service lies in establishing a systematic maintenance mechanism. Qinglong Group establishes an independent digital archive for each project, containing design drawings, material mix ratios, installation records, and key node data, enabling full life-cycle traceability. We have launched a "five-star" maintenance plan: 4 comprehensive inspections in the first year after delivery (once per quarter), 2 routine inspections per year from years 2 to 5, and annual health assessments after 5 years. In the Nanning Wuxiang China Resources Mixc project, by using infrared thermal imaging to detect joint sealing conditions and drone aerial photography to inspect the overall condition of the facade, the team identified and addressed localized sealant aging risks 3 months in advance, avoiding potential safety hazards. This preventive maintenance eliminates problems in their infancy, significantly reducing customers' later repair costs.

Rapid response capability is the touchstone for testing after-sales quality. Qinglong Group has established eight regional service centers across the country, staffed with strictly certified professional repair teams and stocked with emergency supplies such as panels, connectors, and sealants in commonly used specifications. When the Hainan International Convention and Exhibition Center discovered localized panel surface staining after typhoon season, the local service team arrived on site within 2 hours and completed cleaning and repairs within 8 hours, minimizing the impact on exhibition activities. For components requiring factory repair, we have opened a green channel, completing repairs and reinstallation in an average of 15 days—an efficiency 40% higher than the industry average.

Technical support and knowledge transfer are extensions of after-sales service. We provide each customer with a customized "GRC Curtain Wall Maintenance Manual" and conduct professional training for property management personnel, covering daily inspection points, cleaning methods, and common problem handling. Qinglong Group regularly holds customer technical exchange meetings to share the industry's latest maintenance technologies and case experience, helping customers improve their independent maintenance capabilities. Through this comprehensive, in-depth after-sales service, we not only solve current problems but also empower customers to maximize long-term value.
