G40 steel grit offers moderate cutting performance and controlled surface profiling, making it suitable for small and medium metal parts, machinery components, welded parts, steel surfaces and applications that require clean surface preparation with moderate roughness before painting or coating.
G50 steel grit is a finer steel grit size that provides a smoother and more uniform blasting result. It is suitable for light rust removal, fine surface cleaning, thin coating preparation, precision parts and applications where excessive surface roughness should be avoided.
G40 / G50 Steel Grit is widely used in machinery manufacturing, metal fabrication, automotive parts, welded components, steel parts and general industrial surface treatment. These fine steel grit sizes are recommended for customers who need stable cleaning performance, controlled surface finish and suitable surface preparation before painting, powder coating or protective coating.
Steel grit is produced by melting high-quality steel, atomizing it into steel shot, crushing the shot into angular particles, and then screening and heat-treating the material according to required hardness and size.
During production, the steel grit is classified by sieve analysis and inspected for chemical composition, hardness, density and particle size distribution. This helps ensure stable cutting performance and consistent surface roughness during blasting.
1. Controlled Surface Finish
G40 / G50 Steel Grit provides better control over surface roughness compared with coarser steel grit sizes. It is suitable for applications where the surface needs to be cleaned and roughened without creating an overly deep anchor profile.
2. Suitable for Light to Medium Blasting
With fine particle size and angular cutting edges, G40 and G50 steel grit are suitable for light to medium blasting applications. They can remove light rust, thin oxide scale, surface impurities and minor contaminants from metal surfaces.
3. Fine Surface Preparation Before Coating
G40 / G50 Steel Grit can create a moderate and uniform surface profile before painting, powder coating or protective coating. This helps improve coating adhesion while reducing the risk of excessive coating consumption caused by overly rough surfaces.
4. Better Choice for Small and Medium Workpieces
These fine steel grit sizes are suitable for small and medium metal parts, machinery components, welded parts, automotive parts and fabricated steel components that require controlled surface treatment.
5. Flexible Size Selection
G40 steel grit offers moderate cutting performance and is suitable for general surface preparation with controlled roughness. G50 steel grit provides a finer blasting result and is more suitable for lighter cleaning, smoother surface finish and applications where excessive roughness should be avoided.
G40 / G50 Steel Grit is suitable for light to medium blasting, controlled rust removal and fine surface preparation. These fine steel grit sizes are commonly used when customers need a cleaner and more uniform surface finish without creating an excessively deep anchor profile.
They are widely applied in machinery manufacturing, automotive parts production, metal fabrication, welded component cleaning, steel part surface treatment and coating preparation. G40 / G50 steel grit is especially suitable for small and medium workpieces that require stable cleaning performance, controlled surface roughness and consistent surface quality before painting, powder coating or protective coating.
Size Application Guide
G40 Steel Grit
G40 steel grit is suitable for general light-to-medium surface preparation. It provides moderate cutting performance and can remove light rust, thin oxide scale, surface impurities and minor contaminants while creating a controlled surface profile.
It is commonly used for machinery parts, welded components, steel surfaces, fabricated metal parts, automotive components and small to medium steel workpieces before painting or coating.
G50 Steel Grit
G50 steel grit is suitable for finer surface cleaning and smoother blasting results. Compared with G40, it creates a shallower and more uniform surface profile, making it suitable for applications where excessive roughness should be avoided.
It is commonly used for precision parts, small metal components, light rust removal, thin coating preparation, surface finishing and controlled cleaning before painting, powder coating or protective coating.

G40 steel grit is a fine angular abrasive used for light surface cleaning, controlled rust removal and surface preparation before painting or coating. Compared with coarser steel grit sizes such as G18 and G25, G40 creates a finer and more uniform surface profile.
G40 steel grit is suitable for small and medium metal parts, steel components, machinery parts, welded parts and surfaces that require moderate cleaning with better surface control.
G25 steel grit has a larger particle size and provides stronger cutting power with a deeper surface profile. It is suitable for general rust removal, descaling and standard coating preparation.
G40 steel grit is finer than G25. It provides a more controlled cleaning effect and creates a smoother, finer surface profile. It is suitable for applications where the workpiece needs light to medium cleaning without excessive roughness.
