How to Choose Stainless Steel Casework: A 5 Step Checklist
Selecting the right stainless steel casework can feel like a large task. Breaking the process down into logical steps makes the right choices clear. This five step checklist will guide you through the selection process to ensure you specify casework that fits your lab’s needs for safety, efficiency, and longevity.
Step 1: Assess Chemical Exposure
First, you need a clear understanding of the chemicals your team uses daily. This is the most important factor, as it determines which grade of stainless steel you need.
- Create a Chemical Inventory: List every chemical, solvent, and cleaning agent that will contact the casework. Note their concentrations and frequency of use.
- Choose the Right Steel Grade: For general lab use with moderate chemical exposure, Type 304 stainless steel is usually sufficient. If your lab uses harsh corrosives like chlorides, salts, or strong acids, upgrading to Type 316 stainless steel is necessary for long term durability.
Step 2: Define Cleaning and Infection Control Requirements
For many labs, especially in clinical, pharmaceutical, or cleanroom settings, hygiene is a strict regulatory requirement. Your casework must support your facility’s cleaning and sterilization protocols. The non-porous surface of stainless steel is a significant advantage, making it easy to clean. For sterile spaces, look for seamless welds and crevice free designs to eliminate places where contaminants can collect.
Step 3: Map Layout and Workflow
Next, think about how your team works and what they need to store. An efficient lab layout minimizes wasted steps and keeps tools accessible. Your design should support your process, not hinder it.
- What types of samples and equipment require storage?
- Do you need a mix of drawers for small items and cabinets for bulky equipment?
- Would mobile casework on casters add necessary flexibility?
- Where are the main work zones, and what must be stored within arm’s reach?
Answering these questions helps you select the right mix of base cabinets, wall units, and mobile stations.
Step 4: Evaluate Construction Quality
Not all stainless steel casework is built to the same standard. The quality of construction greatly impacts its lifespan and performance. Pay attention to small details to avoid future problems.
- Fully Welded Seams: These provide more strength than spot welded or bolted casework.
- Reinforced Corners: Gussets add structural integrity and prevent warping under heavy loads.
- Durable Hardware: Check the quality of hinges, drawer slides, and handles. They must withstand constant use.
Step 5: Analyze Budget and Lifecycle Costs
Finally, look beyond the initial purchase price and consider the total cost of ownership. Stainless steel may have a higher upfront cost, but its durability and low maintenance often make it the most economical choice over time. Consider the cost to repair or replace less durable materials in five or ten years. The resistance of stainless steel to corrosion and daily wear delivers a better return on investment.
Comparing Stainless Steel with Other Casework Materials
Choosing the right material for your lab involves balancing performance, longevity, and budget. While stainless steel casework is the top choice for harsh environments, other materials like painted steel, wood, and laminate have their place. It is important to understand the trade offs.
For example, wood casework looks classic but fails quickly in a wet lab. Painted steel can be a cost effective choice for a dry lab with low chemical exposure. This comparison will show when the premium performance of stainless steel is worth the investment and when another material might be a better fit.

Decision Scenarios: When to Choose Stainless Steel
Technical specifications are useful, but seeing how stainless steel performs in real world situations makes the choice clearer. Every lab faces unique challenges. In many tough environments, stainless steel is the only viable option. These examples show how its properties deliver benefits for safety, compliance, and long term costs.
Scenario 1: New Construction of a High Containment Lab
In Biosafety Level 3 (BSL-3) or BSL-4 labs, containment is the top priority. These facilities handle infectious agents that can cause serious disease. Every surface must be non-porous and able to withstand harsh decontamination. Stainless steel is mandatory in these settings. Its seamless construction leaves no place for microbes to hide, and it resists harsh sterilants without degrading. Type 316 stainless steel is the standard choice for its superior chemical resistance.
Scenario 2: Renovation of a Clinical Lab
A clinical lab renovating to improve infection control needs materials that are easy to clean and durable. Stainless steel casework meets these needs perfectly. Its smooth, non-porous surface prevents bacterial growth and is easy to sanitize between samples. This helps ensure accurate test results and a safe environment for staff. Unlike laminate or wood, it will not degrade from frequent cleaning with disinfectants.
Scenario 3: An Industrial Quality Control Lab
Industrial QC labs require long term durability. Casework in these environments faces daily use, potential impacts from equipment, and exposure to various chemicals. Stainless steel provides the necessary toughness to handle this demanding setting. It resists dents, scratches, and chemical spills, ensuring a long service life with minimal maintenance. This reduces the total cost of ownership compared to less durable materials that would need frequent repair or replacement.
Integrating Casework with Benches and Workstations
Stainless steel casework is the backbone of a laboratory system. An efficient workflow is created when base and wall cabinets are paired with the right countertops and lab workstations and tables. A well integrated lab supports processes instead of getting in the way.
Creating a Cohesive System
A smart lab layout involves arranging laboratory furniture options to create ergonomic work zones. Base cabinets form the foundation for benches. Topping them with a durable work surface creates a solid station for instruments or sample prep. Wall mounted cabinets keep daily supplies accessible while freeing up valuable bench space.
While a full stainless steel setup offers a seamless look, it is not always the only choice. For work surfaces, pairing stainless steel base cabinets with a stainless steel countertop provides maximum durability and cleanability. However, in areas with extreme heat, an epoxy resin top might be a better option. The choice depends on the specific tasks performed on that surface.
Maintenance and Lifecycle of Stainless Steel Casework
Proper care protects your investment for decades. With simple maintenance, your stainless steel casework will maintain its clean finish and structural integrity, delivering an excellent return on investment.
Recommended Cleaning Practices
The key to stainless steel’s longevity is its protective passive layer of chromium oxide. This layer prevents corrosion but can be damaged by improper cleaning methods.
- Routine Cleaning: Use a soft cloth with mild soap and water for daily wipe downs.
- Wipe with the Grain: Always wipe in the direction of the steel’s grain to prevent micro scratches.
- Rinse and Dry: After cleaning, rinse the surface with clean water and dry it completely to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive cleaners, steel wool, or products containing chlorides, like bleach. These can damage the protective layer and lead to corrosion.
Accessibility and Usability
A well designed lab is also an accessible one. When planning a layout with stainless steel casework, consider accessibility guidelines for reach ranges and clear floor space. Proper planning ensures that all team members can work safely and efficiently. For example, ensuring a 36 inch wide pathway between cabinet rows allows for easy movement and wheelchair access. Good alternative text for images also improves accessibility. For instance, an alt text could be: “A lab technician in a wheelchair accesses a low stainless steel base cabinet with ergonomic pull handles.”
