Manufacturing Sandblasting Perth
Mill scale off plate, pipe spools, weldments and structural members — blasted to the profile your coating spec calls for, then primed.
In short
We blast fabricated steel to the profile your coating system specifies, then prime it before it flash rusts. Batch work, one-offs, stainless and galvanised prep included — in your yard or ours.
What comes off
Mill scale, weld spatter, cutting oil, flash rust and old coating. New steel looks clean and is not: mill scale is a release layer, and paint over scale fails no matter how good the paint is.
We work in your yard or ours, on batches or one-offs, and can prime straight after the blast so the steel does not sit bare overnight.
Mill scale is the whole problem
A coating applied over mill scale is bonded to the scale, not the steel. When the scale lets go — and it always does — the coating comes with it in sheets. Blasting removes it and leaves an anchor profile the primer can key into.
That is why almost every structural coating spec starts with an abrasive blast to a stated cleanliness and profile, not a solvent wipe.
Stainless and non-ferrous
Stainless needs media that will not embed free iron and start rust bloom on a finished job. We use non-metallic abrasive on stainless and keep it segregated from carbon-steel work. Alloy and galvanised surfaces get a lighter sweep to key them for coating without cutting through.
Blast and prime in sequence
Bare steel does not wait. Where you need the steel coated, we sequence blasting and priming so the primer goes on inside the coating window rather than a day later. Tell us the system and we will work to it, or we will hand over inhibited steel for your own painter.
Blasting to a specification, not to a look
Mill scale is not rust
New plate arrives with mill scale — a hard, tightly bonded oxide layer that a coating will happily stick to and then peel away with. Scale has to come off completely, not be roughened, and that takes a harder cut and more passes than surface rust does. Half-removed scale is one of the most common reasons a new fabrication fails inside two years.
Profile is a number
Every industrial coating system states a cleanliness grade and a profile range on its data sheet. Too shallow and the system has nothing to grip; too deep and the peaks read through the film and corrode first. We set media and pressure to the spec you are coating to — see surface profile and standards for what the grades mean in practice.
Weldments, spools and stainless
Weld spatter and slag come off first, or they show through the coating. Stainless and alloy need media that will not embed carbon steel particles into the surface — cross-contamination there causes rust bloom on a metal that should not rust at all. Pipe spools want internal ends capped before we start.
Sequencing with the shop
Blasted steel does not wait. In a Perth workshop, bare plate wants primer the same day, so the blast is booked against the painter's slot rather than the other way round. Tell us the paint date and we work backwards from it.
How the job runs
Scope and spec
Volume, substrate, the cleanliness and profile required, and who is applying the coating.
Set up
Yard or workshop, staging and containment placed, stainless segregated from carbon steel.
Blast
To the stated standard and profile, with media matched to the substrate.
Prime or hand over
Primer inside the coating window, or inhibited steel with photos for your painter.

Common questions
Manufacturing sandblasting — your questions answered
Can you blast to a nominated standard?
Yes. Tell us the cleanliness and surface profile your coating system requires and we will blast to it, then issue photos and a description of the finish for your QA file.
Do you prime after blasting?
We can. Priming inside the coating window is the whole point — bare steel left overnight in Perth humidity will flash rust. If your own painter is applying the system we hand over inhibited steel instead.
Will you contaminate our stainless?
No. Stainless is blasted with non-metallic media and kept segregated from carbon-steel work, so there is no free iron embedded to bloom later.
Can you blast stainless steel without contaminating it?
Yes — with clean, non-ferrous media and dedicated handling. Blasting stainless with used carbon-steel-contaminated abrasive embeds iron particles that rust later, so stainless work runs on its own media.
Do you blast to a specific standard?
Yes. Give us the coating system's data sheet and we prepare to the cleanliness grade and profile range it calls for, rather than to a general clean-metal finish.
Can you prime the steel as well as blast it?
Yes. Applying the primer ourselves closes the gap between blasting and first coat, which is the point at which flash rust undoes the preparation. If your painter is doing the system, we sequence the blast to their booking instead.
What the coating system is asking for
Coating data sheets specify cleanliness and profile. These are the combinations we see most in WA fabrication work.
| Situation | Typical requirement | Why |
|---|---|---|
| New plate with mill scale | Full removal, defined profile | Scale is tightly bonded but brittle — coatings fail with it, not on it |
| Inland structural steel | Clean, moderate profile | Lower corrosivity; the system does the work |
| Coastal or industrial exposure | Higher cleanliness grade, controlled profile | Chlorides and humidity punish any shortfall in preparation |
| Stainless and alloy | Non-ferrous media, dedicated handling | Embedded carbon steel causes rust bloom on metal that should not rust |
