Cleaning big metal things like bridges, ships, and tanks needs strong tools. You can’t use just soap and water. You need something tougher. That’s where steel grit comes in. It scrapes, scours, and clears away rust, paint, and dirt.
But to get good results, you also need to match the right grit with the right blasting machines. When you do this, your work becomes faster, smoother, and cleaner.
This guide will help you pick the best steel grit for your job. You’ll also learn how Itaichu (M) Sdn Bhd helps many workers choose smart tools for surface cleaning and preparation.
What Is Steel Grit?
Steel grit comes from crushed steel balls. The pieces look rough and sharp. They bite into surfaces and help clean or shape them. Unlike smooth sand, these sharp bits don’t slide off. They grab onto rust and strip it away.
Steel grit comes in many sizes. Each size works best for different jobs. Some scrape hard. Others brush gently. But all can help machines, tools, or metal sheets look new again.
Why Use Steel Grit?
Steel grit does a great job because it:
- Chomps through rust and thick layers
- Gives even cleaning
- Lasts longer than soft sand
- Spins well inside blasting machines
- Keeps dust low and clean-up easy
When you pick the right grit and blasting machine, you don’t waste time. You clear surfaces fast and get ready to paint or coat them.
Where Can You Use Steel Grit?
You can use steel grit in many places:
- Shipyards
- Oil and gas plants
- Metal part workshops
- Building sites
- Steel bridges and tanks
Anywhere that metal needs cleaning, steel grit can help.
How to Pick the Right Steel Grit
Not all grit works the same. You need to think about your job, your surface, and your tools. Picking the right grit can save time and keep your surface safe.
Let’s look at the main things you need to check.
1. Grit Size
Grit size tells you how big the pieces are. Big grit cuts deep. Small grit works soft and smooth.
- Tiny grit (G80–G120): These glide over the surface. Good for light cleaning.
- Medium grit (G40–G60): These scrub off paint or light rust.
- Big grit (G18–G25): These carve deep. Use them on thick coatings or heavy rust.
Remember: small number = big grit. Big number = small grit.
2. Grit Strength
Some grit breaks fast. Others stay strong for many uses. You want to match strength to your job.
- Medium-strong grit: Good for most jobs. It stays sharp and lasts long.
- Very hard grit: Cuts fast but breaks quicker. Good for hard surfaces.
The stronger the grit, the more it can scrape—but it may wear out faster too.
3. What Kind of Finish You Want
Sometimes you need a smooth finish. Sometimes you want a rough one so paint sticks better. That’s called a “profile.”
- Rough finish: Choose big grit.
- Smooth finish: Choose fine grit.
Check what your coating needs before you choose.
4. What Blasting Machine You Use
Some blasting machines like fine grit. Some work best with coarse grit. You must check your machine.
- Air blasting machines: Use small or medium grit
- Wheel blasting machines: Handle large grit easily
Itaichu (M) Sdn Bhd helps customers match the right grit to their machines so everything works well.
5. What You’re Cleaning
You must match the grit to the thing you’re cleaning.
- Steel beams or tanks: Use medium or big grit
- Small parts or tools: Use fine grit
- Concrete floors: Use coarse grit for deep cleaning
If you choose wrong, the surface might get scratched or take too long to clean.
Why the Blasting Machine Matters Too
Grit doesn’t work alone. It needs a strong helper—your blasting machine.
These machines throw grit with force so it hits the surface and scrubs it clean.
There are two main kinds:
- Air blasting machines: Blow grit using air. Great for small or tricky parts.
- Wheel blasting machines: Spin fast to fling grit. Best for big jobs like tanks or steel plates.
Your grit and machine must work together like a team. If not, the job takes longer or doesn’t turn out right.
What Happens When You Pick the Right Grit?
When you choose the best steel grit and the best machine, you:
- Clean faster
- Use less grit
- Waste less time
- Get a nice, even surface
- Save money
- Finish jobs better
This helps your business work smarter and grow stronger.
