Shandong Kairuida Building Materials Co., Ltd. (Kairida) is a leading manufacturer of high-strength synthetic fibers in China, dedicated to providing high-performance, environmentally friendly reinforcement solutions for general concrete, civil engineering, municipal engineering, and tunneling projects. As one of only three manufacturers in China capable of producing high-strength macrofibers, we lead the industry with superior quality and innovation, adhering to the philosophy of “Imitate, never surpass.” Our international brand, ConChip, meaning “concrete chip,” symbolizes the core strength it injects into concrete and has established a global reputation for excellence.

           Industry Leader, Technology Pioneer Kairuida, headquartered in Shandong, China, has over 20 years of expertise in the research and production of high-strength synthetic fibers. Our product portfolio includes high-strength macrofibers, monofilament fibers, and environmentally friendly macrofibers. Our products compete with global giants such as BASF and Sika and are ISO 9001 and CE certified. Our high-strength macrofibers boast a tensile strength of >600 MPa, are corrosion-resistant, and are fatigue-resistant, excelling in applications such as shield tunnel segments, industrial flooring, roads, and bridges. For example, our fibers (0.95 mm diameter, 47 mm length, and >620 MPa strength) have proven successful in top-tier tunneling projects. As one of only three manufacturers of high-strength macrofibers in China, we utilize advanced equipment and rigorous quality control to achieve the perfect balance of crack resistance, durability, and cost-effectiveness. From harsh climates at port terminals to highly loaded industrial floors, our fibers ensure long-term stability and safety.

           ConChip: Global Brand Vision Our international brand, ConChip, embodies the concept of “concrete chips,” infusing concrete with intelligent, resilient strength. The ConChip product portfolio includes high-strength macrofibers (>600 MPa) and hybrid fibers (blended with steel fibers) to meet diverse engineering needs worldwide. ConChip exports to the Middle East, Southeast Asia, and Central Asia, supporting Belt and Road Initiative projects and earning global trust. National Projects and Collaboration with Central SOEs: As the designated engineering fiber supplier for major Chinese state-owned construction companies, Kairuida has participated in over 1,500 national projects, including high-speed rail, tunnels, bridges, and ports. Our high-strength, coarse fibers enhance the crack resistance and durability of top-tier shield tunnel segments, ensuring on-time delivery. Our technical team works closely with central SOEs to provide customized fiber solutions and on-site support that meet the highest standards.
            Global Service, Made in Shandong: Kairuida is headquartered in Shandong Province, China, with modern production facilities and an annual production capacity of tens of thousands of tons. We ship from Shandong and offer global customers minimum orders as low as 200 kg and free samples (up to 5 kg, freight collect). In 2024, our exports grew by 28% (according to customs data), expanding into markets such as the Middle East (Saudi Arabia and the UAE) and Central Asia (Kazakhstan and Uzbekistan). Our efficient logistics and professional support ensure our customers receive cost-effective concrete reinforcement fiber solutions. Our Commitment: Kairida upholds the philosophy of “Quality First, Innovation Leading.” In addition to high-performance, high-strength synthetic fibers, we are committed to promoting products made from recycled polypropylene (PP) to promote green buildings and keep pace with global sustainable development trends. Choose Kairida, and we will provide you with industry-leading technology, reliable products, and comprehensive support to help you enhance your project!
