(GLGW), the overseas service center of Zhejiang Shiteng Technology Group Co., Ltd., brings over 16 years of expertise in structured cabling, wireless communication, data center connection solutions, and data application systems. As part of a national high-tech enterprise founded in 2009 and headquartered in Ningbo—home to the world’s largest port—GLGW operates a highly data-driven and intelligent closed-loop workflow. This ensures fully visualized and traceable processes that enhance accuracy, efficiency, and flexibility. Our integrated ecosystem supports over 5,000 manufacturing partners and nearly 200,000 corporate clients globally, backed by 15 supply chain companies, 80+ subsidiaries, and a 1,000+ member service team. With three consecutive years of annual revenue exceeding USD 400 million and an average growth rate above 30%, GLGW delivers professional, high-quality services across the entire commercial loop—from R&D and technical support to logistics and after-sales service.
Among our underground utility identification solutions, the Bulk Buried Location Water Marker Blue delivers a high density polyethylene (HDPE) marker operating at 145 kHz frequency, available in a box of thirty units for large-scale infrastructure marking projects. This bulk buried location water marker is specifically designed for blue color-coded identification of buried water lines, irrigation systems, and potable water infrastructure, allowing utility crews to visually and electronically locate water assets from the surface before excavation. The high density polyethylene construction provides exceptional durability, corrosion resistance, and protection against moisture ingress, soil chemicals, and mechanical stress, ensuring reliable performance for decades when buried underground. Operating at 145 kHz frequency, this water marker is compatible with standard cable and pipe locators used by utility contractors, municipal water departments, and excavation crews worldwide. The box of thirty bulk configuration provides cost-effective volume pricing for large-scale infrastructure projects, utility districts, and contractor inventory, ensuring consistent availability for ongoing marking needs. Manufactured under GLGW's fully traceable closed-loop workflow, each bulk buried location water marker undergoes frequency verification, waterproof testing, and dimensional inspection before shipment, reflecting our commitment to consistent quality. These blue HDPE markers are designed for direct burial alongside water mains, service lines, hydrants, and valve locations, providing positive identification of water infrastructure to prevent accidental strikes during excavation.
