Lab Casework Materials Compared: Steel vs. Wood vs. Phenolic vs. Stainless Steel

Choosing the right casework material is one of the most consequential decisions in a lab build. The material you select affects durability, chemical resistance, cost, lead time, and long-term maintenance. This guide compares the four most common lab casework materials side-by-side.

Quick Comparison Table

Painted Steel Casework

Best for: Teaching labs, general research, clinical labs, QC labs, and budget-conscious projects.

Painted steel is the most commonly specified lab casework material. The epoxy-powder coating provides good chemical resistance for typical lab chemicals, and the steel construction is durable enough for decades of use. It is the most cost-effective option with the shortest lead times, especially from in-stock programs like the Labs USA quick-ship casework line.

Limitations: Not ideal for labs with frequent exposure to strong acids, prolonged moisture, or corrosive fumes. The paint can chip if impacted by heavy equipment.

Wood Casework

Best for: Administrative lab areas, light-duty teaching labs, and facilities prioritizing aesthetics.

Wood casework uses hardwood frames with phenolic or epoxy resin work surfaces. It offers a warmer aesthetic than metal options and can be stained or finished to match existing millwork. However, wood is the least chemical-resistant option and performs poorly in wet environments.

Limitations: Susceptible to moisture damage, warping, and delamination. Higher maintenance over time. Not recommended for wet chemistry, pharma, or any environment with regular chemical exposure.

Phenolic Resin Casework

Best for: Chemical research labs, pharmaceutical labs, wet labs, and any environment with harsh chemicals.

Phenolic resin casework is manufactured from solid phenolic panels — the same material used in the most chemical-resistant countertops. It is completely impervious to moisture, resists nearly all laboratory chemicals, and does not support bacterial growth. This makes it the top choice for demanding environments.

Limitations: Highest cost of the common materials. Longer lead times. Limited color options (typically black or dark gray). Heavier than steel — requires structural consideration for upper cabinets.

Stainless Steel Casework

Best for: Cleanrooms, medical labs, pharmaceutical manufacturing, food science labs, and sterile environments.

Type 304 and 316 stainless steel casework is the standard for environments requiring strict hygiene. It is easy to clean, resistant to corrosion, and meets FDA, NSF, and ISO cleanroom requirements. Labs USA supplies stainless steel casework in standard and custom configurations.

Limitations: Most expensive option. Susceptible to scratching without proper care. Can show fingerprints and smudges in high-traffic areas. Requires stainless-specific cleaning products.

How to Choose the Right Material

1. Identify your chemical exposure — If you work with strong acids, solvents, or corrosives daily, phenolic or stainless is the right choice.
2. Consider your budget — Steel casework delivers 80% of the performance at 40% of the cost of phenolic. Start with steel for general areas and upgrade material in high-exposure zones.
3. Check lead time requirements — If you need furniture fast, steel casework from our quick-ship program ships in days. Phenolic and wood typically require 10+ weeks.
4. Plan for the long term — Phenolic and stainless have the longest useful life. Steel is the easiest and cheapest to replace.
5. Talk to a lab design specialist — Most labs use a mix of materials. Our free lab design service helps you optimize material selection by zone.
