Japan remains a global titan in precision engineering, shipbuilding, and automotive manufacturing. From the shipyards of Nagasaki to the automotive hubs in Aichi, the demand for high-quality Submerged Arc Welding (SAW) flux and electrodes is evolving. With a shift towards "Industry 4.0," Japanese firms are seeking welding consumables that offer not just strength, but consistency, low fume emission, and compatibility with automated robotic systems.
Cost-performance (CP) is the driving factor for the modern Japanese procurement manager. While domestic brands like Kobe Steel offer high quality, Shijiazhuang Tianqiao provides a strategic alternative with 98% quality parity at significantly reduced lead times and costs. Our SJ series fluxes are engineered to meet JIS (Japanese Industrial Standards) equivalents, ensuring seamless integration into existing Japanese production lines.
The trend in Japan is moving toward Sintered Flux due to its superior metallurgical properties and lower energy consumption during the manufacturing process. We are actively innovating in high-alkalinity fluxes that provide excellent toughness at low temperatures—critical for Japan's earthquake-resistant infrastructure and LNG carrier construction.
For Japanese heavy industry, the challenge is often the balance between rapid infrastructure renewal and maintaining "Monozukuri" (craftsmanship) quality. Our welding solutions act as the catalyst for this balance, providing Information Gain through technical transparency. We don't just supply bags of flux; we provide a complete chemical analysis and mechanical property profile tailored for Japanese high-tensile steels.
Founded in 2007 and located 30km southwest of Shijiazhuang, our facility stands as a beacon of manufacturing excellence in the welding material sector. Our strategic location near the 107 national highway and major expressways allows for efficient logistics to Tianjin port, the primary gateway for exports to Yokohama, Nagoya, and Kobe ports.
Our company is structured for total quality management, featuring a specialized R&D Department, QC & Laboratory, and Technical Department. We don't just follow standards; we set them through rigorous testing and innovation in sintered flux and electrode composition.

In the shipyards of Sasebo, our SJ101 High-Alkali Sintered Flux is utilized for multi-wire submerged arc welding of thick plates, ensuring the structural integrity of container ships and oil tankers.
For Tokyo's high-rise construction, our AWS E6013 and E7018 electrodes provide the reliable penetration and slag removal needed for earthquake-resistant steel frames.
Our E71T-1C Gas-Shielded Flux-Cored Wire is optimized for the high-speed robotic welding arms used in Toyota and Honda assembly plants, reducing spatter and post-weld cleanup.
Modern global enterprises, particularly Japanese trading houses (Sogo Shosha), demand more than just a product. They require:
Our products include kinds of welding electrodes with the brand of "Yuanqiao", "Changshan", such as low carbon steel, Iow alIoy steel, heat-resistant steels, low temperature steel, stainless steel, cast iron, hard surfacing welding electrodes. All kinds of sintered flux and various kinds of welding wire and various mixed welding powder. Our products have excellent performance, stable quality, elegant welding molding, good slag removal, good ability to resist rust, Stomata and crack, good and stable deposited metal mechanics performance.
The products are widely used in various nationaI economic fields, such as machinery, metallurgy, petroleum chemical industry, boiler, pressure vessel, the ships, the buildings, and so on. Under the spirit of "Supreme Quality, Honesty, Win-win Cooperation", we create brilliance with our Japanese and global partners.
Yes. Our SJ101 is a fluoride-basic type sintered flux. It provides excellent impact toughness at -40°C, making it ideal for the extreme conditions often faced in Hokkaido infrastructure or offshore platforms.
Absolutely. Our R&D department can adjust the alkalinity (B.I. value) and grain size of the flux to match the specific metallurgical requirements of JFE or Nippon Steel alloys.
We work with tier-1 logistics partners to provide CIF/DAP terms. Flux is packed in 25kg moisture-resistant bags or 1000kg jumbo bags, palletized and shrink-wrapped for maritime protection.
Yes, our flux-cored wires (like E71T-1C) and solid wires are engineered for consistent wire-feeding, which is critical for the robotic automation common in Japanese factories.
