Weifang Jiangchang Chemical Co., Ltd. is located in the Weifang Binhai National Marine Chemical Industry Base. Established in 2015 with a paid-up registered capital of RMB 16.5 million, it is a specialized manufacturer of coastal salt-based raw materials and road maintenance chemicals, integrating R&D, production, customization, distribution, and supporting engineering materials. The company has been recognized as a national-level technology-based small and medium-sized enterprise.
The company operates an independent production facility spanning over 20 mu, divided into five major functional zones: a solid raw material production workshop, a liquid de-icing agent filling workshop, a raw material storage area, a finished product shipping yard, and a quality inspection laboratory. It is equipped with a complete set of automated granulation, filtration, mixing, and filling CNC equipment. Leveraging the local advantages of direct procurement of brine and sea salt from the Binhai region, the company eliminates multiple layers of intermediaries, enjoying distinct advantages in raw material costs and supply stability. Its logistics network connects to national highways and ports nationwide. The plant features a 10,000-ton-class moisture-proof storage space, maintaining ready-to-ship inventories of magnesium chloride, calcium chloride, industrial salt, and various de-icing agents. During the peak winter snow removal season, an emergency supply channel is activated, enabling rapid fulfillment of large-scale government and corporate orders.
The company’s core business segments include basic salt-based raw materials, a full range of de-icing agents, road maintenance chemical products, supporting engineering supplies, as well as import/export and value-added technical services. Its main products comprise magnesium chloride (42%/46% brine flakes, anhydrous magnesium blocks/magnesium powder), calcium chloride (powdered/spherical forms), industrial granular salt, and refined powdered salt; standard composite, low-temperature anti-rust, and non-chlorine eco-friendly solid/liquid de-icing agents with minimum freezing points down to -50°C. The company also supplies dust suppressants, concrete antifreeze agents, cement grinding aids, highway guardrail and slope protection maintenance materials, snow removal equipment, and other engineering support supplies. Additionally, it offers R&D services for environmentally friendly de-icing agents, soil and water pollution remediation, general freight transportation, and value-added services related to raw material import/export.
In terms of technological R&D, the company holds a patent for the roller granulation drip-addition process, which produces uniformly sized de-icing agent granules and boosts melting efficiency by 1.5 times compared to conventional products. It can independently formulate corrosion-inhibiting blends tailored to extreme cold environments down to -50°C. To date, the company has obtained three production patents, three corporate trademarks, and three software copyrights, and employs two mid-level chemical technicians. It has established its own standardized quality inspection laboratory, capable of customizing product content, particle size, and corrosion-inhibiting ratios according to customer-specific operating conditions.
Regarding quality control, the company has implemented a triple-layer inspection system: comprehensive incoming raw material checks, random sampling during production, and re-inspection before shipment. This ensures strict oversight of magnesium chloride and calcium chloride purity, de-icing agent corrosion inhibition levels, and dust suppression and solidification performance. Each batch of products comes with an authoritative test report, supports third-party inspections upon request, and allows for customized formulations featuring low corrosivity, environmental friendliness, or ultra-high purity.
In terms of market services, the company’s products are distributed across more than 30 provinces and municipalities nationwide, having participated in over 60 national bidding projects involving highways, airports, and municipal sanitation. It provides long-term services to clients in sectors such as transportation groups, municipal sanitation, road and bridge engineering, magnesite building materials, aquaculture, mining, and cold-chain warehousing. The company has developed a standardized end-to-end service system: one-on-one pre-sales consultation, free sample delivery, factory tours, and customized formulation assistance; ready-to-ship products can be loaded within 48 hours, while custom-made items are completed within seven days, with partner logistics fleets delivering directly to project sites. During sales, the company offers guidance on product storage and spreading ratio techniques. After-sales, it guarantees unconditional returns, replacements, or reshipments for damaged goods or products failing to meet specified standards, and provides year-round technical consulting to continuously optimize supply solutions for loyal customers.
Looking ahead, Jiangchang Chemical will continue to deepen its expertise in domestic road maintenance, magnesite building materials, and water treatment, constantly expanding its eco-friendly salt-based product portfolio, broadening its import/export operations, and extending its road maintenance industry chain. Committed to green and low-carbon production, the company aims to become a leading custom manufacturer of salt-based de-icing agents in northern China.
