SEPPE White Fused Alumina for Anti-skid Surfacing Materials is a high-purity, hard and angular white alumina aggregate used for anti-skid road surfacing, bridge deck overlays, industrial flooring, ramps, stairs and high-friction surface treatment systems. Its clean white color, high hardness and controlled aggregate size help provide durable anti-slip texture and stable surface friction.
Product: White Fused Alumina for Anti-skid Surfacing Materials for anti-skid surfacing, flooring aggregate and high-friction surface projects
Other Names: White Fused Aluminum Oxide, White Aluminum Oxide, White Corundum
Country of Origin: China
Manufacturer of Material: SEPPE TECHNOLOGIES
White Fused Alumina is produced by melting high-purity alumina in an electric arc furnace, followed by cooling, crystallization, crushing, magnetic separation, screening and particle size classification.
Compared with brown fused alumina, white fused alumina has higher purity, lower iron content and a cleaner white appearance, making it suitable for abrasive applications where surface cleanliness and controlled finishing are important.
SEPPE supplies macro grits, micro powder, aggregate sizes and customized particle size grades according to final application and purchase requirements.
High Purity: Typical Al2O3 content is around 99.3%-99.5%, supporting clean abrasive performance and stable quality.
High Hardness: Mohs hardness around 9 provides sharp cutting ability for grinding, blasting, polishing and surface preparation.
Low Iron White Abrasive: White appearance and controlled Fe2O3 content help reduce contamination risk in precision finishing and decorative surface treatment.
Stable Chemistry: Controlled SiO2, Na2O and Fe2O3 levels help support consistent abrasive performance from batch to batch.
Wide Particle Size Range: 0-1mm / 1-3mm / 3-5mm are available, with other particle sizes supplied upon request.

High-purity alumina selection → Electric arc furnace fusion → Cooling and crystallization → Crushing → Magnetic separation → Screening and classification → Final inspection → Packaging.
The process is designed to control alumina purity, impurity level, magnetic material, particle size distribution and visual whiteness for stable application performance.
Chemical composition testing for Al2O3, SiO2, Na2O, Fe2O3 and other indicators according to grade requirements.
Particle size distribution inspection according to ordered macro grit, micro powder or aggregate specification.
Magnetic material control, moisture review and visual whiteness inspection to support clean abrasive performance.
Batch COA, TDS, sample testing and third-party inspection can be arranged according to purchase requirements.
▸ Common packaging includes jumbo bags, 25 kg bags and 40 bags on a pallet. Customized packaging can be discussed according to order requirements.
▸ Palletizing, container loading, private label packaging and inspection support can be arranged upon request.
▸ Store in dry conditions and protect bags from moisture, contamination and package damage before use.
It can be used for anti-skid road surfacing, bridge decks, ramps, stairs, industrial flooring, parking areas and high-friction surface treatment systems.
0-1mm is often used for finer texture, 1-3mm for common anti-skid surfacing, and 3-5mm for coarser friction demand. Final choice depends on resin system, surface design and project requirement.
Excess fines may affect aggregate distribution, bonding with resin and surface texture, so dust/fines control supports stable friction performance.
Yes. Particle size report, batch COA, retained sample support and packaging inspection can be arranged according to order requirements.
▸ Store in dry conditions and protect bags from moisture, contamination and package damage before application.
