Aluminum Oxide 36 mesh

Aggressive Cutting Action for Industrial Surface Preparation

The 36 mesh grade is one of the coarsest commonly specified sizes in the aluminum oxide family. It is designed to remove heavy rust, thick mill scale, and tough existing coatings from steel and other hard substrates. The sharp, blocky grain shape creates a pronounced surface profile, which is critical for the mechanical adhesion of high-build protective coatings, thermal spray deposits, and non-skid surfacing.

Key Performance Characteristics

Aluminum Oxide 36 mesh delivers a unique combination of hardness and friability. It is harder than most metallic and mineral abrasives, allowing it to cut quickly. Simultaneously, its controlled breakdown under high-velocity impact prevents excessive embedment and helps maintain a consistent surface roughness (Rz/Ra) across the workpiece. This balance is essential for blasting contractors who must meet strict SSPC or NACE surface preparation standards.

Common Blasting Applications

This coarse grit is typically used in air blast systems with a venturi nozzle or in direct-pressure blast pots for maximum particle velocity. It is also suitable for select wheel blast machines where a deep etch is required. Typical applications include preparing structural steel for intumescent fireproofing, profiling concrete for epoxy overlays, and creating a bonding surface on hard metals prior to thermal spraying. It is also used for matte finishing and deburring of hard alloys.
