Understanding Steel Grit in Surface Preparation
Steel grit is a high-performance metallic abrasive widely used in surface preparation, cleaning, and treatment processes. Manufactured by crushing cast steel shot, steel grit provides aggressive cutting action, making it an ideal choice for removing rust, paint, scale, and contaminants from surfaces. Industries such as automotive, aerospace, shipbuilding, foundries, and construction use steel grit for effective surface profiling before applying coatings.
As a leading manufacturer of steel shot, steel grit, and metallic abrasives, we offer premium-quality abrasives that enhance the efficiency and longevity of blasting operations.
Types of Steel Grit Grades
Steel grit is categorized based on its hardness and application suitability. The three primary grades include:
1. High-Carbon Steel Grit (GH Grade – Above 60 HRC)
- Extremely hard and angular
- Ideal for aggressive cleaning and surface etching
- Best suited for air blasting and etching of hard metals
2. Medium-Hard Steel Grit (GL Grade – 50-60 HRC)
- Balanced hardness and durability
- Used for general surface cleaning and coating preparation
- Suitable for shipbuilding, railways, and industrial applications
3. Soft Steel Grit (GP Grade – 40-50 HRC)
- Softer and rounder, reducing surface damage
- Used in wheel blasting operations and surface polishing
- Ideal for automobile parts and delicate surfaces
Choosing the Right Steel Grit for Your Application
Selecting the appropriate cast steel grit depends on your specific application, material type, and desired surface profile.
- For heavy-duty rust and coating removal → Use GH grade steel grit
- For general cleaning and moderate etching → Opt for GL grade steel grit
- For polishing and minimal surface roughness → Choose GP grade steel grit
