Powder-coated stainless steel allows these products to reap all the inherent benefits of stainless, while also gaining protection, durability, and aesthetic improvements. Is stainless steel recyclable?
Benefits of Powder Coated Stainless Steel
Applying powder-coated finishes to stainless steel components and products provides several significant benefits that make it an appealing finishing option:
Enhanced Aesthetics
Powder coating offers virtually endless color and finish options to fit the exact needs of a product. Matte, gloss, metallic, wrinkled, textured, and more—if you can dream it, it can be created with a powder coat. This allows stainless steel parts to take on eye-catching colors and designs that attract attention.
Improved Durability
The powder-coated layer cured onto stainless steel resists scratching, scuffing, and abrasion much better than standard stainless steel alone. It also provides an extra barrier of protection against corrosion. This improved durability extends the service life of stainless products.
Easier Maintenance
The slick powder-coated surface repels water, dirt, grease, and more. This non-stick property keeps stainless steel components cleaner and looking for longer compared to uncoated stainless, while also being easier to clean when needed.
How to Powder Coat Stainless Steel
Successfully powder coating stainless steel requires a series of key steps to ensure proper adhesion and performance:
Surface Preparation
Meticulous surface prep is crucial for the powder to bond correctly to stainless steel. The surface must be thoroughly cleaned of any oils, dirt, and residue using alkaline cleaning solutions. Media blasting then roughens up the surface to enable mechanical adhesion and provide a tooth for the powder to cling to.
Common media blasting materials include:
- Aluminum oxide
- Glass beads
- Walnut shells
- Plastic pellets
- Sodium bicarbonate
This aggressive roughening also removes any external corrosion that could cause early failure of the coated finish.
Powder Application
With the substrate properly pretreated, the powder coating material can now be applied using either a spray gun or a fluidized bed dipping process. Spraying electrostatically charges the powder so it wraps around and clings to all surfaces of a part. The dipping method fully submerges items into a bed of air-fluidized powder—great for coating small parts.
Baking
Once fully coated in powder, the stainless steel parts enter high-temperature ovens to melt, flow out, gel, and cure the powder into a smooth, uniform, protective finish. Temperatures typically range from 300° to 400° F depending on the powder’s chemistry. The length of time needed for full cure also varies by powder type, from just 10 minutes up to one hour. Proper baking is crucial to create finishes that achieve maximum hardness and durability.
Applications for Powder Coated Stainless Steel
Stainless metal, while more desirable with powder lined finishes, combines the sturdiness of stainless-steel with the addition of colourful colours, textures, and stepped forward protection. This mixture makes powder lined stainless-steel an fantastic choice for a big selection of makes use of. It is highly sought after for decorative architectural accents such as railings, bollards, and screens.
In the realm of food service, it finds applications in restaurant and kitchen equipment including appliances, work tables, and shelving. It is likewise ordinary in industrial restrooms, where it’s far used for walls, furniture, dispensers, and waste cans. In healthcare and scientific settings, powder lined chrome steel is applied for medical institution and laboratory equipment like carts, shelves, and fume hoods.
The transportation sector benefits from it in the form of hitches, running boards, and trim. Furthermore, it serves a variety of purposes in furniture making for both indoor and outdoor items, including desks, cabinets, and racks. Retail displays also take advantage of this material for racks, hooks, and sign frames.
Beyond these applications, powder coated stainless steel is employed in exercise and playground equipment, as well as in industrial machinery, tools, and robotics. Essentially, its uses are nearly limitless, with the right surface preparation and coating process allowing stainless steel products to achieve performance benefits far exceeding those of mill finish stainless steel alone.
