Which GRC Manufacturer Offers Good After-Sales Service? Lifetime Warranty and Qinglong Group's Maintenance System

The after-sales service level of a GRC manufacturer directly affects the long-term stable operation of a project. Quality service should cover four dimensions: "rapid response, professional repair, regular inspection, and lifetime follow-up." Qinglong Group has built a three-dimensional support network of "16 service centers nationwide + 400 hotline + digital work order system," and commits to: providing solutions for non-urgent issues within 48 hours and having technicians on site within 12 hours for emergencies. In the post-typhoon inspection at the Hainan International Convention and Exhibition Center, we completed a comprehensive survey of 120,000 square meters of roofing within 24 hours, preventively reinforced 3 hidden hazards, and avoided potential losses of millions of yuan. After-sales service is the touchstone of a brand's promise.

Standardized Emergency Response Mechanism Ensures Timeliness

A three-tier response system has been established: Level 1 issues (minor defects) receive remote guidance within 7 days; Level 2 issues (localized damage) are handled on site within 72 hours; Level 3 issues (major hazards) have experts stationed on site within 12 hours. All cases are entered into a database, forming a solution library for typical problems. In 2023, 87 after-sales requests were processed, with an average closure time of 5 days and a customer satisfaction rate of 98.5%.

Preventive Maintenance System to Prevent Problems Before They Occur

The "Golden Shield Program" has been launched: contracted customers enjoy annual free inspections, with drone infrared scanning used to detect hollowing and ultrasonic thickness gauges used to assess performance. A digital operation and maintenance file has been established for the Shenzhen Yirui project, with each panel independently numbered to enable predictive maintenance.

Lifetime Quality Traceability and Knowledge Transfer

Each project is equipped with a dedicated QR code; scanning it allows access to production data, installation records, and maintenance history. Free performance testing is provided for projects in use for more than 5 years, along with recommended upgrade solutions. Maintenance training is provided to customers to enhance their self-maintenance capabilities.

Quality after-sales service is the cornerstone of long-term cooperation. Through systematic maintenance and proactive care, Qinglong Group provides customers with the peace of mind of "one cooperation, lifetime worry-free."
