How to Choose Painted Steel Casework: A 5-Step Checklist
Selecting the right lab storage ensures safety, efficiency, and longevity. Follow this five-step checklist to determine if painted steel casework is the best fit for your facility's needs.
1. Identify Chemicals and Cleaning Agents in Use
First, list the chemicals, reagents, and disinfectants used daily in your lab. While painted steel resists mild acids, bases, solvents, and common cleaners like alcohol or bleach solutions, it is not intended for constant contact with highly corrosive substances. This assessment will confirm if its chemical resistance is sufficient.
2. Evaluate Humidity and Corrosion Risk
Consider your lab's ambient environment. Facilities in coastal regions or areas with high humidity may increase the risk of corrosion if the casework finish is compromised. In these conditions, an enhanced pretreatment or a more robust powder coat may be advisable. For extreme environments, stainless steel is a more suitable long-term solution.
3. Determine Storage Types and Load Requirements
Think about what you will store. Standard steel cabinet drawers are typically rated for 100 to 150 pounds, suitable for glassware and most supplies. If you need to store heavy equipment or bulk materials, specify heavy-duty drawer slides and reinforced shelving. Matching load capacity to your inventory is critical for safety and durability.
4. Plan for Flexibility and Reconfiguration Needs
Decide if your lab layout needs to be adaptable. Fixed casework is permanently installed for maximum stability. In contrast, modular or mobile cabinets on casters allow you to reconfigure your space as projects and equipment change. Many labs use a hybrid approach with fixed perimeter cabinets and mobile islands.
5. Review Budget, Lead Time, and Service Integration
Finally, align your selection with your project's budget and timeline. Painted steel casework generally has a lower upfront cost and shorter lead time than stainless steel. Plan for the integration of services like power, data, and plumbing. The performance of your casework is also affected by the benches and worktops you pair it with. Explore options for lab workstations and tables and lab bench systems to create a complete solution.

Configuration Options for Painted Steel Casework
Painted steel casework is a modular system that can be configured to meet specific laboratory workflows. Combining different cabinet types creates an efficient and organized workspace.
- Base Cabinets: These form the foundation for countertops and provide under-counter storage with door, drawer, or combination units.
- Wall Cabinets: Mounted above work surfaces, they offer easy access to frequently used glassware and reagents. Options include solid or glass doors.
- Tall Cabinets: Floor-to-ceiling units provide maximum storage capacity for bulk supplies, equipment, or personal protective equipment (PPE).
- Mobile Cabinets: Set on heavy-duty casters, these units offer flexible storage that can be moved where needed.
- Specialty Units: Sink base cabinets, fume hood bases, reagent shelving, and pegboards integrate directly into the casework system.
- Power and Data: Service raceways and cutouts for electrical and data ports can be integrated into the casework and benching.
Pairing fixed perimeter casework with modular lab benches creates a highly effective mixed fixed-mobile layout, allowing for future flexibility.
Finish and Corrosion Protection
The longevity of painted steel casework depends on its finish. The process begins with heavy-gauge steel, typically 16 or 18 gauge, which is chemically pretreated to clean and etch the surface for adhesion.
A powder coat finish is then applied electrostatically, ensuring an even layer of polymer particles covers all surfaces. The parts are cured in an oven, where the powder melts and fuses into a hard, durable shell that resists chipping, scratching, and mild chemical exposure. Standard colors include white, grey, and black, with custom colors often available. For coastal or highly corrosive environments, an enhanced pretreatment or a move to stainless steel is recommended. Review the various finishes for steel cabinets.
Integration with Benches and Work Surfaces
Painted steel casework integrates seamlessly with common lab work surfaces and bench frames. Cabinets can be mounted to lab bench systems or installed as a standalone base for countertops like epoxy resin, phenolic resin, or stainless steel.
Proper integration includes planning for service integration, such as plumbing and electrical in service raceways. For facilities in seismic zones, casework must be securely anchored to the floor and walls according to local building codes to ensure stability. This creates a cohesive and functional workspace from our full line of lab workstations and tables.
