3-Stage Chemical Wash System
High-Volume Chemical Cleaning and Conversion Coating
If your parts need thorough, consistent cleaning and a corrosion-resistant conversion coating before painting, powder coating, or assembly, our 3-stage chemical wash system delivers reliable results at production volume. This process is designed for manufacturers who need high-throughput parts cleaning without the wear and part-handling concerns of abrasive blasting.
Based in Florence, AL, Tri-State Metals provides 3-stage chemical wash processing to manufacturers throughout Northwest Alabama, Southern Tennessee, and Northeast Mississippi.
How the 3-Stage Chemical Wash Process Works
Our large Continuous Conveyor Spray Washer moves parts through a three-stage chemical wash process built for high-volume production. A pump and piping system transfers chemical solution from a reservoir tank to a set of risers. Nozzles attached to the risers direct a jet or swirl of solution onto the parts, physically and chemically removing soils and contaminants while producing a conversion coating on the part substrate.
Because parts move continuously through each stage, this process supports consistent, repeatable results across high production volumes — with no manual handling required between stages.
What This Process Does For Your Parts
- Removes oils, soils, and contaminants from the part surface
- Produces a conversion coating that improves paint and powder coat adhesion
- Improves corrosion resistance ahead of finishing or storage
- Prepares parts for painting, powder coating, or assembly
- Supports continuous, high-volume production with consistent results
- Cleans parts without the abrasive wear of sandblasting
Supporting Manufacturers Across Industries
Our 3-stage chemical wash system supports manufacturers and businesses across a variety of industries, including:
A Reliable Pretreatment Partner
Manufacturers depend on consistent, dependable pretreatment before painting or coating. Our 3-stage chemical wash system is designed to integrate into your production process while helping you:
- Maintain consistent cleaning and conversion coating quality across high volumes
- Improve downstream coating adhesion and corrosion resistance
- Reduce manual part handling between cleaning stages
- Support continuous production schedules
- Prepare parts for powder coating, wet paint spraying, or assembly
Frequently Asked Questions
A conversion coating is a thin chemical layer produced on the part surface during the wash process. It improves how well paint or powder coating adheres to the part and adds a layer of corrosion resistance.
Sandblasting uses abrasive media to mechanically strip a surface. Our 3-stage chemical wash system uses a chemical spray process instead, which is well suited to high-volume continuous production and parts that don't require abrasive treatment.
Yes — chemical wash pretreatment is commonly used ahead of both powder coating and wet paint spraying to improve adhesion and finish durability. Ask about combining processes for your project.
The process removes oils, soils, and other surface contaminants that can interfere with coating adhesion, preparing parts for painting, powder coating, or assembly.
