Our Journey — Built on Quality, Driven by Trust

For more than two decades, Dingzhou Jinlong Metal Products Co., Ltd. has been dedicated to the development and manufacturing of high-quality welding consumables. From a local manufacturer to an international supplier serving customers across multiple continents, our journey has always been guided by one fundamental principle: quality is the foundation of long-term business.

▶ 2004 — The Beginning of Our Journey

In 2004, Dingzhou Jinlong Metal Products Co., Ltd. was officially established, marking the beginning of our journey in the welding consumables industry.

In the same year, we introduced our first international brand, Copper Bridge, covering a wide range of welding materials. From the very beginning, our vision was not simply to manufacture welding products, but to build a reliable brand that customers could trust for years to come.

▶ 2005–2015 — Expanding Beyond Borders

Over the following decade, we continued to expand our production capabilities, with annual production exceeding 50,000 metric tons.

At the same time, our products gradually entered international markets across the Middle East, South Asia, South America, and Africa.

Through continuous improvement in manufacturing processes, product consistency, and quality control, Copper Bridge products earned increasing recognition from customers around the world. Repeat business and long-term customer relationships became the strongest proof of our commitment to quality.

▶ 2016–2020 — Quality Meets International Standards

As our international business continued to grow, we strengthened our quality management system and obtained ISO certification, further aligning our manufacturing and quality-control processes with international standards.

During this period, our overseas business continued to expand steadily, with annual export sales exceeding USD 2 million.

More importantly, we established long-term partnerships with customers in different regions and gained valuable experience in meeting diverse market requirements, product specifications, and application needs.

▶ 2021–2024 — Building Brands for Global Markets

As different markets developed their own product preferences and requirements, we continued to strengthen our international brand strategy.

We introduced additional brands tailored to specific markets, including ZETA for the Venezuelan market and SHARP for the African market, while continuing to expand the presence of Copper Bridge across more countries.

Our focus was not simply on entering new markets, but on building localized, reliable, and sustainable partnerships with distributors, importers, wholesalers, and industrial customers.

▶ 2025–Present — Taking Copper Bridge to the United States

In 2025, Copper Bridge reached another important milestone with the official launch of its U.S. operations in Riverside, California, including the establishment of our first U.S. warehouse.

This step represents more than geographical expansion. It reflects our commitment to being closer to our customers, improving supply responsiveness, strengthening local service capabilities, and building a truly global welding consumables network.

From China to the Middle East, South Asia, South America, Africa, and now the United States, our international footprint continues to grow.

Looking Ahead — Quality Without Compromise

Our journey is still continuing.

As markets evolve and customer expectations become increasingly demanding, we remain committed to continuously improving our product quality, manufacturing technology, quality control, service capabilities, and global supply network.

We believe that a strong business is not built on a single order, but through consistent quality, dependable service, mutual trust, and long-term cooperation.

For more than 20 years, this philosophy has remained at the heart of Jinlong Metal Products.

From our factory to the world, we are committed to making every weld stronger — and every partnership longer.

Quality. Reliability. Partnership.
