Shot blasting is a surface treatment in which fine media, such as metal shot, glass beads or ceramic particles, is propelled at high speed against a surface to clean it, texture it and give it an even, uniformly matte appearance. On custom awards, shot blasting removes machining marks and creates a soft, non reflective finish that reads as understated and premium.
The short answer
If you have ever handled an award with a smooth, satin grey surface that seems to absorb light rather than bounce it, you have most likely handled a shot blasted piece. The technique replaces the busy, uneven look of a raw machined or printed surface with a calm, consistent texture. It is both a preparation step and a finish in its own right, and it is one of the quiet workhorses of high-end award making.
How shot blasting works
The piece is placed in a controlled blasting cabinet where a stream of media is directed at its surface under pressure. Each particle strikes the surface and leaves a tiny impression. Multiplied across millions of impacts, these impressions merge into a uniform texture. By changing the media type, size and pressure, we control how fine or coarse the resulting finish is. Fine glass bead blasting yields a smooth, almost velvety matte, while coarser media creates a more pronounced tooth. The process also strips away oxidation, loose particles and surface contaminants, leaving a clean base for any coating that follows.
Shot blasting as preparation
Beyond its own aesthetic, shot blasting is a crucial preparation step. Plating, painting, powder coating and gilding all adhere far better to a clean, slightly textured surface than to a smooth or contaminated one. The gentle roughness gives coatings something to grip, which improves durability. When we plan a mixed finish award, shot blasting is often the first operation, setting up every layer that comes after. See our materials overview for how substrate choice affects the blasting approach.
Media types and their effects
- Glass beads: produce a bright, smooth satin matte, favoured for clean contemporary awards.
- Ceramic media: gives a durable, consistent finish well suited to pieces that will be handled.
- Steel shot: a more aggressive option for heavy cleaning and pronounced texture.
- Aluminium oxide: a sharp media that cuts quickly, used where strong texturing or heavy prep is needed.
Why designers choose a blasted finish
A shot blasted surface signals restraint. Where high polish shouts, matte whispers, and for many premium brands that quieter register is exactly right. A blasted body pairs beautifully with a single polished or gilded highlight, letting one detail catch the eye against a calm ground. The matte surface also hides fingerprints and minor handling marks far better than a mirror finish, which matters for awards passed from hand to hand at a ceremony. Explore how we apply this thinking in our custom trophy service.
Combining shot blasting with other finishes
Shot blasting is rarely the whole story. It is a foundation that other techniques build on. A blasted metal award might then be selectively polished on its edges through bevelling, plated in two tones for contrast, or patinated with a black oxide in its recesses. On 3D printed forms in particular, a light blast is invaluable for evening out the surface before coating, turning a printed part into something that feels crafted rather than manufactured.
Consistency across a series
One of the great strengths of shot blasting is repeatability. Because the process is controlled by measurable variables, we can reproduce the same finish across an entire run of awards, so every winner in a cohort receives a piece that matches its neighbours exactly. That consistency is one reason blasting is so common in recognition programmes that repeat year after year. Our in house facility in Antwerp lets us hold that standard tightly and answer any specification questions within 24 hours.
Care and durability
A shot blasted finish is robust and low maintenance. There is no mirror surface to scratch and no bright plating to dull, so the piece ages gracefully. Cleaning is as simple as a soft dry or slightly damp cloth. Because the texture is uniform, any light marking blends in rather than standing out, which keeps a blasted award looking fresh for years of display.
How Fabit uses shot blasting
We treat shot blasting as both a design choice and an engineering step. Whether it is the final look of a minimalist award or the hidden groundwork beneath a rich plated finish, it is executed in house with controlled media and pressure. If you are picturing a soft matte trophy or want advice on preparing a printed form for plating, start a brief in our design studio and we will recommend the right media and sequence for your piece.
Frequently asked questions
Is shot blasting the same as sandblasting? They are closely related. Sandblasting is one form of abrasive blasting using sand, while shot blasting typically uses metal shot or engineered media for a more controlled, cleaner result.
Does shot blasting weaken the award? No. It affects only the very surface, cleaning and texturing it without meaningfully removing structural material.
Can shot blasting be applied to only part of a piece? Yes. With masking we can blast selected areas to create contrast between matte and polished regions.
Is a blasted finish suitable before plating? Ideally, yes. The clean, lightly textured surface improves how well plating and coatings adhere.
