Surface preparation is a critical step in steel fabrication. Proper cleaning ensures strong coating adhesion, corrosion resistance, and overall structural longevity. Traditionally, steel structures were cleaned using methods such as manual grinding, wire brushing, sandblasting, or chemical cleaning. While these methods have been widely used, they often present limitations in terms of efficiency, consistency, and environmental impact.
In contrast, through-type shot blasting machines offer a modern, automated approach to steel surface treatment. Companies like Jiangsu Chuandu Technology Co., Ltd. have pioneered these solutions, enabling steel fabricators to achieve superior results in a fraction of the time.

Traditional Cleaning Methods: Limitations and Challenges
1. Manual Grinding and Wire Brushing
Manual methods require significant labor and time, particularly for large structures. Inconsistent operator technique can lead to uneven surfaces, leaving some areas insufficiently cleaned or roughened. These inconsistencies affect coating adhesion and may compromise long-term corrosion resistance.
2. Sandblasting
While sandblasting improves surface roughness and removes rust effectively, it has several drawbacks:
High dust generation that requires significant cleanup and environmental protection
Labor-intensive preparation and cleanup
Limited scalability for high-volume production
3. Chemical Cleaning
Chemical treatments can remove rust and grease, but they pose environmental and safety concerns. Disposal of chemical waste must be carefully managed, and prolonged handling can be hazardous for workers. Additionally, chemical cleaning cannot provide the surface strengthening benefits that shot peening or blasting offers.
Advantages of Through-Type Shot Blasting Machines
Through-type shot blasting machines overcome many limitations of traditional cleaning methods. These machines allow continuous, automated processing of steel structures, providing uniform surface treatment at high throughput.
1. Continuous Automated Operation
Unlike batch cleaning, through-type machines feature automated conveyors that transport steel plates, beams, and welded assemblies through the blasting chamber continuously. This reduces manual labor, minimizes handling errors, and significantly increases production efficiency.
2. Uniform Surface Treatment
Through-type shot blasting ensures that every part of the steel structure receives consistent cleaning and surface roughening. This uniformity is essential for strong coating adhesion and superior corrosion protection.
3. Surface Strengthening
In addition to cleaning, shot blasting induces compressive stress on the steel surface, enhancing fatigue resistance and structural durability. Traditional chemical cleaning or manual methods cannot provide this added benefit.
4. Dust and Environmental Management
Chuandu machines integrate advanced dust collection systems, such as Venturi-type water dust removal, cartridge collectors, and pulse-jet reverse-air systems. These solutions maintain a clean working environment and comply with environmental regulations, unlike sandblasting or chemical cleaning methods, which can generate hazardous dust or waste.
5. Flexibility and Customization
Chuandu’s machines can be configured to handle a wide variety of steel components, from long beams and plates to complex welded assemblies. Conveyor speeds, blasting intensity, and media type can be adjusted to match specific production needs.
Applications in the Industry
Through-type shot blasting machines have become indispensable across multiple sectors:
Construction and Steel Fabrication: Cleaning and strengthening structural beams, plates, and channels
Automotive and Aerospace: Preparing high-strength components that require enhanced fatigue resistance
Wind Power: Surface treatment of towers, rotors, and large steel structures
Shipbuilding: Ensuring corrosion-resistant surfaces for hulls and frameworks
Heavy Machinery and Petroleum: Improving surface properties before painting, coating, or assembly
By enabling continuous processing, these machines are ideal for both small-scale workshops and large-scale industrial fabrication lines.
