In 2025, the fluctuations in the market environment and the acceleration of technological iterations have presented every enterprise with the real test of "how to survive and develop". Pro-liner choice is: to return to the essence and focus on the field we are good at - providing truly reliable and efficient solutions for the safety and renewal of urban underground pipe networks.

For us, the so-called development is not about pursuing grand narratives, but about overcoming one specific and difficult technical hurdle after another; it is not about depicting a broad blueprint, but about making our products stand the test at every construction site; It's not just empty talk about the future of the industry，but about accumulating the right to speak tomorrow by serving every customer who trusts us now and doing every project at hand well.

This annual review is a concentrated presentation of our pragmatic efforts over the past year. It records our global breakthroughs in ultra-large diameter repair technology, the stable performance of our materials under extreme working conditions, and the precious recognition and suggestions we have received from industry experts and partners. We believe that the "hard power" to solve specific problems and the "reliability" that is worthy of trust are the most certain corporate values in this era of uncertainty.

Looking back at 2025, every technological breakthrough, every industry honor, and every successful case recorded in Pro-liner yearbook was not behind the abstract name of the company, but was jointly written by more than 400 Pro-liner people with professionalism, sweat and ingenuity. From countless overnight tests in the R&D center to unwavering persistence at project sites regardless of wind and rain; from the pursuit of millimetre-level precision on the production line to the careful consideration of every detail of customer needs - it is these specific and subtle efforts that have converged into a majestic force driving us to continue moving forward.

We are well aware that technology has boundaries, but people's exploration and perseverance can constantly expand them; pipes have diameters, but the collaboration and wisdom of the team can infinitely extend their significance. Looking ahead, the challenges remain, but our confidence is stronger. This confidence comes from our technical reserves for continuous innovation, and more importantly, from our team that has clear goals, can fight tough battles, and is worthy of trust.

In 2026, we will continue to walk with all strivers. In the mission of consolidating the "underground lifeline" of cities, Pro-liner not only repairs pipes, but also builds trust; not only creates commercial value, but also realizes the common growth of individuals and teams.

In the upcoming year 2026, we pay tribute to every Pro-liner people who has been working diligently in silence.The future is here, let's go to the mountains and seas together.
