When it comes to outdoor furniture, the coating matters just as much as the design. Whether you’re sourcing commercial outdoor furniture for a park, school, or public facility, the finish must stand up to UV exposure, moisture, harsh chemicals, and the wear and tear of high-traffic areas.
At Premier Polysteel, we manufacture all of our products using first-rate steel completely coated with plastisol (polyvinyl chloride)—an incredibly durable coating designed to perform in the harshest environmental conditions. But how does it compare to other options like thermoplastic coatings?
In this article, we’ll break down the key differences between plastisol vs thermoplastic coat options and explain why plastisol is the preferred coating for long-lasting, weather-resistant outdoor applications.
Why the Right Coating Matters for Outdoor Furniture
In outdoor settings, extreme weather, direct sunlight, moisture, and temperature fluctuations all take a toll on surfaces—especially metal and steel. To protect steel from corrosion, you need more than paint. You need a protective coating that offers:
- UV resistance
- Water resistance
- Chemical resistance
- A durable finish with low maintenance requirements
Yet not all coatings deliver the same performance under pressure.
What Is Plastisol Coating?
Plastisol coating is a type of liquid PVC (polyvinyl chloride) applied through a dipping process. The metal—often steel—is fully immersed in plastisol, then heated to fuse the material into a thick, flexible protective layer. This method is known as plastisol dip coating.
Key Advantages of Plastisol-Coated Steel
- Forms a hardened surface that resists cracking, peeling, and fading
- Offers excellent protection from UV radiation, harsh chemicals, and moisture
- Contains a built-in UV coating inhibitor for prolonged outdoor performance
- Withstands temperatures ranging from sub-zero winters to scorching summers
- Eliminates the need for repair coating or solvents over time
- No visible flaking or bubbling—even after prolonged exposure
- Plastisol is not conducive to flame.
This makes plastisol-coated furniture ideal for parks, schools, recreational facilities, and any site exposed to high traffic and extreme weather conditions.
What Is Thermoplastic Coating?
Thermoplastic coatings are applied as a dry powder using an electrostatic spray, then melted onto the metal surface in a curing oven. Commonly used in powder coatings, thermoplastics offer a touch-soft texture and decent aesthetic appeal, but they don’t always hold up in harsh environments.
Drawbacks of Thermoplastic Coating in Outdoor Use
- May trap moisture, leading to internal corrosion on most metals
- Textured thermoplastic leaves can develop drip marks and inconsistencies over time
- Typically offers less chemical resistance than plastisol
- May require repair coating after heavy use
- Degrades faster under UV exposure, especially without a proper UV inhibitor
- Often less effective in extreme weather conditions
- May be flammable and spread fire when exposed to high heat
Side-by-Side Comparison: Plastisol vs. Thermoplastic Coating
| Feature | Plastisol Coating | Thermoplastic Coating |
|---|---|---|
| Application Process | Plastisol dip coating (liquid PVC) | Electrostatic dry powder spray |
| Curing | Yes—melts into a hardened surface | Yes—melts into a thermoplastic shell |
| UV Protection | High—coating UV inhibitor included | Moderate to low (depends on formulation) |
| Chemical Resistance | Highly resistant | Moderate |
| Moisture Protection | Excellent—sealed layer | May trap moisture |
| Durability in High Traffic | Superior | Moderate |
| Maintenance | Low maintenance | May require repair coating |
| Aesthetic Appeal | Smooth, glossy appearance | Often textured or matte |
| Resistance to Extreme Weather | Weather resistant | May fade or degrade |
| Use in Harsh Environments | Preferred coating | Less suitable |
Common Applications for Plastisol-Coated Products
Premier Polysteel uses plastisol-coated steel across all our commercial outdoor furniture, including:
- Picnic tables
- Benches
- Trash cans
- Fixtures installed on masonry surfaces
Our plastisol-coated products are used in many industries, from education to municipal parks, because they’re built to handle high effort use, chemical spills, UV exposure, and extreme weather—without breaking down.
Why Premier Polysteel Chooses Plastisol for All Outdoor Furniture
We’ve tested other coatings—and the verdict is clear. Plastisol coating offers the most exceptional protection for steel in long-term outdoor use. Here’s why:
- Plastisol forms a thicker, more reliable protective coating than standard powder coatings
- It doesn’t require solvents or frequent reapplication
- It’s better at resisting harsh chemicals, salt spray, and vandalism
- Our coating thickness is optimized for strength and longevity
- It’s visually consistent, with no visible fade variations or weak spots
This ensures every piece of Premier Polysteel furniture is built to last—year-round, even in the most extreme weather conditions.
Final Verdict: Which Outdoor Finish Lasts Longer?
When comparing plastisol vs thermoplastic coat, plastisol clearly outperforms for long-term durability, protection, and maintenance-free use in outdoor settings.
If you’re responsible for sourcing commercial outdoor furniture that can handle UV exposure, corrosion, chemicals, and moisture, plastisol is the preferred coating for your investment.
