Sandblast Cabinet — Steel Processing Equipment

Overview

Our Sandblast Cabinet provides controlled media blasting for surface preparation, rust removal, and coating preparation on fabricated steel parts.

Operations & Applications

The sandblast cabinet is used to prepare metal surfaces before powder coating, painting, or welding. Media blasting removes mill scale, rust, old coatings, and surface contaminants to create a clean, profiled surface that ensures superior coating adhesion. The enclosed cabinet design contains the blasting media for a clean work environment, and the dust collection system maintains air quality. This is a critical step in our finishing process that directly impacts the quality and durability of the final coating. The cabinet accommodates parts up to 36 inches in any dimension and uses a range of blast media including aluminum oxide, glass bead, and steel grit, selected based on the base material, the surface profile required, and the downstream coating or finishing process. Aluminum oxide provides aggressive material removal for heavy rust and scale on structural steel, glass bead delivers a uniform satin finish on stainless steel and aluminum without dimensional change, and steel grit creates the angular surface profile preferred for maximum powder coating adhesion. Our operators adjust blast pressure, nozzle distance, and media type to achieve the specific surface profile called out in coating specifications — typically measured in mils of anchor pattern depth using replica tape or a surface profile gauge. For parts that will receive our in-house powder coating, the sandblast cabinet works in direct sequence with our pre-treatment wash and coating line, ensuring that freshly blasted surfaces are coated before any flash rust can develop. The cabinet is also used for cosmetic finishing on stainless steel parts, creating uniform brushed or matte finishes that enhance the appearance of architectural and consumer-facing components.

This coating & surface prep equipment operates at Ameristeel's Michigan steel fabrication facilities, serving automotive manufacturers and metal fabricators throughout Southeast Michigan and the greater Metro Detroit region.

Why Choose Ameristeel

Proper surface preparation is the foundation of a quality coating, and Ameristeel's sandblast cabinet ensures every part gets a clean, profiled surface before entering our powder coating line. The enclosed design keeps our facility clean while the dust collection system maintains air quality for our team. By controlling surface preparation in-house, we eliminate the inconsistency that comes from relying on parts arriving with unknown surface conditions from outside vendors. Every part that enters our powder coating line receives a documented level of surface preparation, which directly translates to consistent coating adhesion, corrosion resistance, and appearance across your entire production order. The sandblast cabinet also serves as a restoration tool for refurbishment projects — stripping old paint, powder coat, and surface corrosion from existing components so they can be re-coated and returned to service at a fraction of the cost of new fabrication. For weld-critical applications, media blasting before welding removes mill scale and contaminants from the joint area, improving weld quality and reducing the risk of porosity and inclusions.
