Steel Abrasives for Heavy Machinery & Equipment
Durable abrasives for earthmoving and mining equipment, gear and shaft peening, structural fabrication blasting, and weld cleaning — built to handle the toughest heavy-duty surface preparation.
Built for the Toughest Equipment Duty
Heavy machinery for mining, construction, and material handling endures abrasive wear, impact, and corrosion that few other sectors match. Surface preparation of thick fabricated structures and the peening of high-torque powertrain components are decisive factors in how long this equipment survives in the field.
Large weldments and chassis frames require aggressive, efficient blasting to reach bare metal and develop the anchor profile that high-build protective coatings need. Gears and shafts depend on controlled shot peening to lift bending fatigue and pitting resistance in transmissions and final drives.
Macloid Metalix supplies tough, highly recyclable steel shot, steel grit, and cut wire shot with certified hardness, chemistry, and sieve analysis on every batch — delivering low cost per part across demanding production schedules.

Key Heavy Machinery Applications
From mining equipment fabrication to gear peening, our abrasives serve the full range of heavy-duty surface preparation needs.
Earthmoving & Mining Equipment
Excavator booms, dozer blades, dump truck bodies, and bucket assemblies face abrasive wear and heavy impact in mining and construction. Steel grit blasting strips scale, rust, and weld spatter from thick fabricated structures, creating the angular anchor profile needed for the high-build protective coatings these machines depend on.
- ✓Strips mill scale, rust, and spatter from heavy fabrications
- ✓Creates angular profile for high-build wear coatings
- ✓Cleans buckets, booms, blades, and truck bodies
- ✓Achieves Sa 2.5 cleanliness per ISO 8501-1
Steel Grit G25 – G50
Gear & Shaft Shot Peening
Gears, splined shafts, and drive components in transmissions and final drives carry enormous torque and cyclic loading. Controlled shot peening induces compressive residual stress in tooth roots and fillets, raising bending fatigue strength and pitting resistance to extend the service life of heavily loaded powertrain components.
- ✓Induces compressive stress in gear tooth roots and fillets
- ✓Improves bending fatigue and pitting resistance
- ✓Controlled Almen intensity per SAE J443 saturation curves
- ✓Coverage verification on critical load-bearing zones
Cut Wire Shot or Steel Shot S330
Structural Fabrication Blasting
Heavy structural weldments, chassis frames, and base structures must be cleaned to bare metal before painting and assembly. Steel shot and grit blasting removes scale and oxidation across large fabricated surfaces in a single efficient pass, producing a uniform finish that maximises coating life on equipment exposed to harsh duty.
- ✓Cleans chassis frames and structural weldments to bare metal
- ✓Uniform finish across large fabricated surfaces
- ✓Recyclable media lowers cost per fabricated structure
- ✓Prepares surfaces for primer and protective coatings

Weld Cleaning & Descaling
Welded joints on heavy equipment carry slag, oxide, and heat-affected scale that must be removed before inspection and coating. Targeted shot blasting cleans weld seams and surrounding zones, exposing the bead for visual and NDT inspection while creating a sound surface for durable coating adhesion.
- ✓Removes slag, oxide, and weld spatter from joints
- ✓Exposes weld beads for visual and NDT inspection
- ✓Cleans heat-affected zones without gouging base metal
- ✓Prepares weld zones for sound coating adhesion
