By using high-speed steel shot to impact the metal surface, the process efficiently removes rust, mill scale, oxide layers, welding residue and surface contaminants, producing a clean and uniform surface suitable for subsequent painting, coating, galvanizing or fabrication.

Shot blasting is an important surface treatment process in structural steel fabrication because proper surface preparation can significantly improve coating adhesion and help provide long-term corrosion protection.

We provide customized shot blasting services according to component dimensions, steel grade, project specifications and required surface condition.

Typical Processing Capability

Why Steel Shot Blasting?

Raw steel normally contains rust, mill scale, oxide layers and other contaminants that may reduce the adhesion of protective coatings.

Shot blasting creates a cleaner and more consistent surface profile before painting or coating.

The process helps:

• Remove surface rust

• Remove mill scale

• Remove oxide layers

• Clean welded steel components

• Improve surface consistency

• Improve coating adhesion

• Prepare steel for primer and paint

• Improve corrosion protection performance

• Reduce manual surface cleaning

• Increase production efficiency

Our Shot Blasting Process

1. Material Inspection

Steel components are checked before processing to confirm dimensions, surface condition and fabrication requirements.

2. Loading

Steel beams, plates or fabricated components are positioned on the shot blasting production line or processing equipment.

3. Shot Blasting

High-speed steel abrasive is projected onto the steel surface to remove rust, scale and contaminants.

4. Surface Cleaning

Residual abrasive, dust and loose contaminants are removed after blasting.

5. Surface Inspection

The processed steel surface is visually inspected to verify uniformity and cleanliness.

6. Further Processing

After shot blasting, components can proceed directly to:

• Primer Coating

• Painting

• Welding

• Assembly

• Galvanizing Preparation

• Packing

• Export Shipment

One-Stop Structural Steel Fabrication Service

In addition to shot blasting, we can support complete steel fabrication projects.

Our services can include:

Drawing Review → Material Preparation → CNC Cutting → Drilling → Welding → Assembly → Shot Blasting → Painting → Inspection → Packing → Shipment

This integrated production process helps customers reduce the number of suppliers involved in their projects and simplifies procurement and quality control.

FAQ

1. What is steel shot blasting?

Steel shot blasting is a surface preparation process that uses high-speed steel abrasive particles to remove rust, mill scale, oxide layers and contaminants from steel surfaces.

2. What steel products can be shot blasted?

We can process steel beams, columns, plates, channels, angles, welded structures, frames, brackets and other fabricated steel components.

3. Can you provide Sa 2.5 surface preparation?

Yes. Surface preparation requirements such as Sa 2, Sa 2.5 or Sa 3 can be discussed and produced according to the applicable project specification and inspection requirements.

4. Can shot blasting be done before painting?

Yes. Shot blasting is commonly performed before primer and protective coating application because it helps prepare a clean surface for coating adhesion.

5. Can you process large structural steel components?

Yes. Large beams, columns, welded frames and other structural steel components can be processed according to equipment capacity and component dimensions.

6. Do you only provide shot blasting?

No. We can also provide cutting, drilling, welding, fabrication, assembly, painting, inspection, packing and other steel processing services.
