Powder Coated Stainless Steel Casework
Powder coating can be applied over a stainless steel substrate when a project needs a particular color, texture or surface characteristic. Procurement documents should identify both the stainless alloy and the complete coating system because the coating does not replace the substrate’s material properties.
Key planning considerations
- 304, 316 or other verified stainless substrate
- Surface preparation and pretreatment
- Powder resin and manufacturer
- Cure temperature and process control
- Color, gloss, texture and film thickness
- Adhesion and performance testing
- Cut edges, scratches and field repair
- Cleaning compatibility and warranty documentation
Build a quote-ready equipment scope
Useful RFQs identify the facility type, project stage, intended workflow, quantities, room constraints, available utilities, required options and expected delivery timing. When drawings or bid documents are available, include them during project review so equipment requirements can be coordinated around the full scope.
Why facilities specify stainless laboratory casework
Stainless steel can provide a durable, non-porous and readily cleanable surface for laboratory cabinets and work areas. Corrosion and stain performance varies with alloy grade, surface finish, fabrication quality, contaminants, cleaning agents and chemical exposure, so project specifications should document the real operating conditions.
Casework can be configured with adjustable shelves, drawers, compartments, sink bases, lockable storage, mobile units and coordinated laboratory workbenches. USPE supports both standard configurations and project-specific layouts for institutional purchasing.
Specify the substrate and finish separately
“Stainless,” “powder coated” and “steel” describe different parts of a material system. A reliable submittal identifies the substrate alloy or steel type, surface preparation, coating chemistry when applicable, color and gloss, fabrication details and required performance documentation.
Do not treat 316 as immune to bleach, chlorides or strong acids. Performance depends on concentration, temperature, contact time, surface condition, crevices and rinsing. Likewise, a powder coating can be damaged or breached; the exposed substrate then determines corrosion behavior.
High-temperature alloy data is not a finished-worktop rating. The safe operating temperature for laboratory casework must account for the complete assembly, including reinforcement, seams, adhesives, coatings, cabinetry, nearby stored materials and connected utilities.
