Steel Abrasives for Agricultural Equipment
From tractor frame blasting before e-coat to tillage tool descaling and sprayer tank preparation — consistent, high-throughput abrasives for the demands of agricultural OEM production lines and component manufacturers.
Corrosion protection starts at the blast cabinet
Agricultural machinery faces one of the harshest operating environments in manufacturing: constant contact with wet soil, fertilisers, pesticides, and herbicides; outdoor storage through winter; and abrasive wear from tillage operations. Paint systems on tractor frames and implements are expected to last 10–15 years under these conditions.
Meeting that durability target begins with the quality of the blasted surface. Mill scale left on fabricated frames will eventually delaminate and lift the paint above it. Forging scale on tillage tools, if not fully removed, creates weak points where corrosion penetrates. Only a thoroughly blasted surface — Sa 2.5 minimum, with the correct anchor profile for the primer system — gives a paint line a realistic chance of meeting OEM warranty targets.
Macloid Metalix supplies SAE J827 certified steel shot and SAE J1993 certified steel grit in grades optimised for agricultural production lines, with sieve analysis and hardness certificates issued for every batch.

Key agricultural equipment applications
Surface preparation needs vary across the range of agricultural equipment. Here is how steel abrasive is applied at each stage.
Tractor frame and implement blasting
Tractor chassis, loader frames, and implement frames are fabricated from structural steel that carries mill scale and welding oxides from the fabrication process. Shot blasting before primer application removes all surface contamination and creates a uniform anchor profile that ensures the paint system adheres over the full design life of the machine — even under the flexing loads and chemical exposure of agricultural work.
- ✓Removes mill scale and weld scale before e-coat or powder coat application
- ✓Uniform Sa 2.5 cleanliness on complex fabricated frames
- ✓Controlled Ra 3–6 µm profile for cathodic electrocoat adhesion
- ✓Compatible with inline conveyor blasting systems for high-volume production
Steel Shot S230 – S330
Tillage tool descaling
Ploughshares, disc blades, chisel points, and cultivator tines are forged or cast components that arrive with heavy forging scale and surface oxides. This scale must be completely removed before hardening, surface treatment, or painting. Shot blasting is significantly faster than chemical pickling and leaves no residual acid that could affect heat treatment metallurgy.
- ✓Complete forging scale removal from ploughshares and discs
- ✓No acid residue — safe for post-blast heat treatment operations
- ✓Cleans complex geometry: tapers, cutting edges, and bolt holes
- ✓Higher throughput per hour compared with tumble-barrel or chemical methods
Steel Shot S280 – S390
Sprayer tank interior cleaning
Agricultural sprayer tanks — fabricated from mild steel or stainless steel — require internal blast cleaning to remove weld scale, rust, and contamination before anti-corrosion lining application. The interior geometry of large spray tanks makes access difficult; small-diameter blast nozzles and appropriate abrasive selection allow operators to reach all internal surfaces and achieve the cleanliness required for lining adhesion.
- ✓Internal surface preparation for chemical-resistant lining systems
- ✓Reaches weld seams, corners, and baffles with nozzle blasting
- ✓Sa 2.5 cleanliness ensures chemical-resistant lining bonds reliably
- ✓Prevents osmotic blistering under aggressive agrochemical contact
Steel Grit G40 – G25
Corrosion protection for farm machinery
Agricultural machinery operates in a uniquely aggressive corrosion environment: fertiliser residues, agrochemicals, soil acids, and seasonal outdoor storage combine to attack unprotected or poorly coated surfaces. A properly profiled and cleaned substrate, correctly primed and topcoated, can provide 10–15 years of corrosion protection even under field conditions.
- ✓Achieves Sa 2.5 or Sa 3 for maximum coating system performance
- ✓Profile matched to primer specification for optimal adhesion
- ✓Removes rust and old failed coatings from in-service machinery refurbishment
- ✓Supports extended warranty paint systems for OEM applications

Why steel abrasive for agricultural equipment?
Agricultural production lines demand abrasives that perform consistently at high volume without driving up media consumption costs.
Hardness matched to forging scale
Forging scale on tillage tools is significantly harder than atmospheric rust. Steel shot at 42–52 HRC has the hardness to fracture and dislodge it efficiently — mineral abrasives break down too rapidly under these conditions.
High throughput for volume production
Tractor OEMs and implement manufacturers run high-volume production lines. Steel abrasive recycle rate (300+ cycles) keeps blasting cost per part low and production throughput consistent.
Consistent profile for paint lines
Modern agricultural OEM paint lines use automated e-coat or powder coat systems that require tight anchor profile tolerances. Steel shot delivers consistent Ra and Rz values batch after batch.
Closed-loop recovery
Blast wheels with magnetic separators recover and recycle steel abrasive continuously. This eliminates the abrasive waste and disposal costs that come with expendable slag or mineral media.
