In engineering construction, many people focus on product price. However, what truly determines the smooth progress of a project are these two key points: 👉 When a problem arises, can they respond quickly? 👉 Once on-site, can they actually solve the problem? Today, we share a real-life case of GULISHI's frontline technical service.

On-site symptoms: ⚠️ If left unhandled, these types of issues often lead to: Upon receiving the feedback, the GULISHI technical team responded immediately: ✔ Rapid Response Mechanism ✔ On-Site Execution 👉 Took only about 1 hour from arrival to problem resolution Through on-site inspection, the technical personnel quickly pinpointed the core of the problem: 👉 The conclusion was clear: ❗ This was a construction operation and equipment issue, NOT a quality issue with the rebar sleeve product. This step is absolutely critical—many suppliers can only "exchange goods," but they cannot "determine the root cause."
