H-Beam Roller Conveyor Shot Blasting Machine | Structural Steel Solution
The H-Beam Roller Conveyor Shot Blasting Machine is a specialized, high-performance solution engineered for the continuous surface treatment of heavy-duty H-beams, I-beams, and complex structural components. Specifically designed for workpieces with a high height-to-width ratio, it features an optimized blast wheel layout to ensure superior vertical surface coverage where standard machines often fall short.
Built for large-scale structural steel fabricators, this system delivers a consistent Sa 2.5 surface finish while significantly reducing manual re-work and maximizing throughput in demanding industrial environments.
Product Introduction
Our H-Beam Roller Conveyor Shot Blasting Machine represents the definitive choice for the structural steel industry. While universal roller machines are ideal for flat plates, this specialized series utilizes a 3D multi-angle blasting geometry. This ensures that the high-velocity abrasive stream reaches the deep “web” and both sides of the “flanges” simultaneously, achieving an ISO 8501-1 compliant cleanliness level in a single pass.
Powered by high-efficiency turbines and ABB electrical components, the machine is built to handle ultra-heavy structural loads without vibration. Managed by an intelligent Siemens PLC system, the conveyor speed and blasting intensity can be precisely synchronized with your welding and cutting lines, offering a seamless, automated workflow for bridge construction, high-rise buildings, and heavy engineering.

QH69 Roller Conveyor Shot Blasting Machine for Structural Steel: FAQ'S
How does this H-Beam machine differ from a standard Q69 roller machine?
Standard roller machines are optimized for flat plates. The H-Beam Roller Conveyor Shot Blasting Machine features a specific 3D turbine layout. The blast wheels are positioned at angles that guarantee the abrasive reaches the inner surfaces of the H-beam flanges and webs, which standard machines often miss.
Can I use this machine for general steel plates as well?
Yes. While it is optimized for tall profiles, the roller conveyor and wide chamber allow it to process standard steel plates and other profiles with ease, making it a highly versatile asset for structural steel shops.
What is the maximum height of structural steel it can process?
Our QH69 series can handle profiles up to 2500mm in height. For extra-large bridge or stadium components, we offer customized chamber dimensions and additional turbine configurations to meet your specific load and size requirements.
How do I maintain a consistent Sa 2.5 finish?
The machine’s automated abrasive replenishment system and VFD-controlled conveyor speed ensure that, regardless of the initial rust grade, the H-Beam Roller Conveyor Shot Blasting Machine delivers a uniform, high-quality Sa 2.5 finish for superior paint adhesion.
