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 of a company's overall strength and long-term partnership value, directly affecting the long-term stable operation after project completion and the owner's return on investment. As the Qinglong Group with 28 years of deep expertise in the GRC field, we have built a three-dimensional after-sales service system of 'preventive maintenance + rapid response + lifetime tracking'. Through nationwide interconnected service stations, a 7×24-hour technical support hotline, and a digital operations and maintenance platform, we deliver one-stop service guarantee with response within 2 hours, solutions issued 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 Hainan International Convention and Exhibition Center, the Qinglong after-sales team, through regular inspections, professional cleaning, and partial repairs, ensures 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 creates an independent digital archive for each project, containing design drawings, material mix ratios, installation records, and key node data, achieving full lifecycle 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 in years 2-5, and annual health assessments after year 5. In the Nanning Wuxiang China Resources MixC One project, through infrared thermal imaging to detect joint sealing conditions and drone aerial photography to inspect the overall condition of the facade, we discovered and addressed localized sealant aging risks 3 months in advance, avoiding potential safety hazards. This preventive maintenance eliminates problems at the bud, 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 commonly used panel specifications, connectors, and sealants. When localized panel surface staining was found at the Hainan International Convention and Exhibition Center after typhoon season, the local service team arrived on site within 2 hours and completed cleaning and repair within 8 hours, minimizing the impact on convention and exhibition activities. For components requiring factory repair, we have opened a green channel, completing repair and reinstallation within an average of 15 days, with 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 key points of daily inspection, cleaning methods, and handling of common issues. Qinglong Group regularly holds customer technical exchange meetings to share the industry's latest maintenance technologies and case experience, helping customers enhance their independent maintenance capabilities. Through this comprehensive and in-depth after-sales service, we not only solve current problems but also empower customers to maximize long-term value.
