Comprehensive After-Sales Service

Our professional technical team is available 24/7 to answer customer questions about product installation, usage, and maintenance. We also provide detailed technical documents (material certificates, and performance test reports) to help customers use our products correctly.​

In the rare case of product quality issues (verified through joint inspection), we offer flexible solutions: free replacement, repair, or refund — depending on customer needs and the nature of the issue. We prioritize fast response, aiming to provide a solution within 48 hours of receiving a customer complaint.​

We conduct regular follow-up visits with customers (3 months, 6 months, 1 year after delivery) to understand product usage status, collect feedback, and provide proactive maintenance suggestions. This long-term communication helps us continuously improve our products and services, while building lasting trust with customers.
