On December 4, 2025, China Eastern Airlines flight MU745 landed smoothly at Ezeiza International Airport in Buenos Aires, Argentina. In a "water arch" ceremony, which symbolizes the highest courtesy in civil aviation, the first direct flight route between China and Argentina was officially launched. This air passage spanning the Eastern and Western Hemispheres not only builds a bridge for personnel exchanges but also brings supply chain innovation opportunities to hardware trading enterprises that are deeply engaged in the international market.
The 4 pcs fixing anchor with Hex bolt from Hebei Duojia Metal Products Co., Ltd. serves as
a core fastening component in the construction and industrial fields. The technical characteristics and application scenarios of the 4 pcs fixing anchor with Hex bolt precisely meet the current upgrade demands of the global infrastructure market. This product, made of high-quality carbon steel as the base material, features a dual surface treatment process to meet the anti-rust requirements in different environments. Blue-white zinc is suitable for indoor dry environments, while color zinc is more appropriate for outdoor damp or highly corrosive scenarios, such as bridges and wind power equipment. The 4 pcs fixing anchor with Hex bolt consists of a hex bolt, a flat washer, and a nut, and achieves a firm anchorage with the concrete base through the expansion of the expansion sleeve when the bolt is tightened.
In 2025, the global construction fastener market exhibited a dual characteristic of "infrastructure demand-driven and anti-corrosion performance upgrade". In South America, due to the concentrated implementation of new energy power stations and affordable housing projects, the demand for economic carbon steel anchor bolts increased by 19% year-on-year. The core value of Hebei Duojia's 4 pcs fixing anchor with Hex bolt lies in the dual advantages of "modular fastening + convenient installation": the four-piece set includes the anchor bolt body, hex bolt, flat washer, and expansion sleeve, enabling rapid anchorage of prefabricated components. Compared with traditional split anchor bolts, the installation efficiency is increased by 40%. In terms of load transmission, this product converts external tensile force into frictional force of the base through the mechanical bite of the expansion sleeve, effectively adapting to scenarios such as low-rise building curtain wall fixation, photovoltaic bracket foundation anchoring, and industrial equipment base installation.
