Core Advantages

Superior Wear Resistance

Made of high-purity carbon steel with precise heat treatment (quenching & tempering), our steel shot features a uniform martensitic structure. The hardness is strictly controlled between HRC 40-65, and the wear loss rate is as low as ≤8% per 1000 cycles, which is 30% lower than ordinary steel shot on the market. This reduces the frequency of material replacement and extends the service life.

High Cleaning Efficiency

With a roundness of ≥0.98, the steel shot has excellent impact performance. When hitting the workpiece surface, it can evenly transmit impact energy, effectively removing rust, scale, and oil stains without causing excessive surface damage. The cleaning efficiency is increased by 25% compared with irregular abrasive materials, and the surface roughness after treatment meets Ra 1.6-6.3μm, which meets the pre-painting and pre-plating requirements.

Significant Cost Savings

The low wear loss rate and high recycling rate (up to 8-12 times) directly reduce the consumption of abrasive materials. According to customer feedback, using our steel shot can reduce the total abrasive cost by 25% on average. At the same time, the high cleaning efficiency shortens the production cycle, reduces labor and equipment operation costs, and further optimizes the overall production cost.

Stable Supply Capacity

We have three fully automated production lines with a monthly output of 20,000 tons. The raw material warehouse has a standing stock of 5,000 tons, and the finished product warehouse can store 8,000 tons. We can meet the urgent order needs of 500 tons per day, and the delivery time for regular orders is controlled within 20 working days to ensure that your production is not interrupted.

Application Scenarios

Casting Industry

Application: Cleaning of casting sand, scale, and burrs for gray iron, ductile iron, and steel castings.

Advantage: The moderate hardness (HRC 45-50) avoids damage to the casting surface, and the uniform particle size ensures consistent cleaning effect. It is suitable for automatic shot blasting machines and manual shot blasting equipment.

Steel Structure Industry

Application: Rust removal and derusting of steel plates, angle steels, H-beams, and steel pipes before painting and anti-corrosion.

Advantage: It can quickly reach the Sa2.5-Sa3.0 derusting grade, enhance the adhesion of the coating, and extend the anti-corrosion life of the steel structure by 30%.

Automotive Manufacturing

Application: Surface treatment of auto parts (engine blocks, gears, axles) to remove oxide scale and improve surface finish.

Advantage: High-purity material (impurity content ≤0.5%) avoids contamination of parts, and the precise particle size control ensures the dimensional accuracy of parts.

Hardware and Tool Industry

Application: Polishing and deburring of hardware tools (wrenches, pliers, screws) and daily hardware (faucets, door handles).

Advantage: The smooth surface of the steel shot does not scratch the workpiece, and the polishing effect is uniform, improving the product appearance quality.

Shipbuilding and Marine Engineering

Application: Rust removal and maintenance of ship hulls, offshore platforms, and marine pipelines.

Advantage: Strong wear resistance and corrosion resistance, suitable for harsh marine environments, and the treatment effect meets the marine anti-corrosion standards.

Quality Certification

Our steel shot abrasive has passed a number of international certifications, including ISO 9001 Quality Management System Certification, SAE J444 Standard Certification, and CE Certification. Each batch of products undergoes strict quality testing, including composition analysis, hardness testing, particle size screening, and wear resistance testing, and a complete quality inspection report is provided to ensure that the products meet the customer's requirements.

Production Equipment & Capacity

We adopt advanced automatic production equipment, including medium-frequency induction furnaces, centrifugal atomization equipment, and automatic heat treatment lines, which realize the full automation of raw material smelting, forming, heat treatment, and screening. The production process is strictly controlled by the PLC system, ensuring the stability and consistency of product quality. The annual production capacity reaches 240,000 tons, which is among the top in the industry

Inventory Management

We have established a scientific inventory management system, with a 10,000-square-meter automated warehouse. The common specifications (SSG1.0-SSG3.0) have a standing stock of more than 5,000 tons, and the special specifications can be produced and delivered within 20-30 working days. The inventory status is updated in real-time, and customers can query the stock and arrange orders at any time.

Customer Cases & Feedback

Large Casting Enterprise in Shandong, China

"We have been using this steel shot for 2 years. Compared with the previous supplier's products, the wear loss is significantly reduced. The original 10 tons of steel shot can be used for 15 days, but now it can be used for 22 days. The cleaning efficiency is also improved, and the production capacity of the shot blasting machine has increased by 20%. The total cost of abrasive materials has been reduced by about 28%." - Mr. Li, Production Manager

Steel Structure Manufacturer in Texas, USA

"We need a lot of steel shot for the production of steel structures for oil pipelines. The steel shot from this supplier has stable quality, and the derusting effect can reach Sa3.0 every time. The delivery is also very timely. Last month, we had an urgent order of 800 tons, and they delivered it within 30 days, which helped us avoid the risk of delayed delivery. We are very satisfied with their service." - Ms. Sarah, Purchasing Director

Auto Parts Supplier in Guangdong, China

"The surface finish of auto parts is very important for us. This steel shot has a good polishing effect, and the parts after treatment have a uniform luster, which meets the requirements of our customers in Europe. The impurity content is very low, and there is no problem of product contamination. We have established a long-term cooperative relationship with them." - Mr. Wang, Quality Control Director
