What is PBR Metal Siding?
A Simple Metal Siding Guide to Strength, Durability, and Finishes
When you’re looking for siding that’s tough, low-maintenance, and sharp-looking, PBR metal siding is one of the most popular choices. Whether you’re building a barndominium, a barn, a shop, or even a modern home, understanding how PBR panels are made and how their color finishes are applied will help you make a smart, long-lasting choice.
PBR Metal siding is the default siding on all our metal building kits. We have other options available if you prefer a more traditional look, but if you want metal siding, we think PBR is your best choice – and here’s why.
What is PBR Metal Siding?
PBR Metal siding stands for Purlin Bearing Rib siding. It’s a steel panel system designed for strength, easy installation, and good looks. The panels are shaped with a series of wide and narrow ribs (raised sections) that run vertically across the wall. These ribs give the panels extra stiffness, help shed water, and add to the overall appearance.
PBR metal panels are called “purlin bearing” because the design allows the panels to overlap and rest securely on framing members (purlins), resulting in a stronger and more reliable installation.
Key Features of PBR Siding:
- Material: Made from heavy-duty steel, often galvanized or Galvalume-coated for rust and corrosion resistance.
- Shape: Panels have a repeating pattern of flat sections and raised ribs, typically spaced 12 inches apart.
- Strength: The ribbed profile makes the panels more resistant to bending, impacts, and heavy weather.
- Installation: Panels overlap and fasten directly to wall framing or furring strips, creating a tight, weather-resistant seal.
Why Builders and Homeowners Choose PBR Metal Siding
PBR panels are used across all types of projects because they offer major benefits:
- Durability: They can handle tough weather conditions, including wind, rain, snow, and sun, without warping, rotting, or cracking like traditional materials.
- Low Maintenance: No need for constant painting, staining, or sealing. A simple wash keeps the panels looking good for years.
- Versatile Appearance: Available in a wide range of colors and finishes, from bold modern looks to more traditional tones.
- Cost-Effective: Steel panels last for decades, reducing the need for costly repairs or replacements over time.
You’ll find PBR siding on barndominiums, warehouses, barns, commercial buildings, and even stylish homes with a modern farmhouse design.
How Color is Applied to PBR Metal Siding
The color you see on PBR panels isn’t just regular paint sprayed on after installation. It’s factory-applied using a coil coating process that is specifically designed to bond tightly to metal and withstand harsh outdoor conditions.
The Paint Application Process:
- Steel Preparation: The raw steel coils are cleaned to remove any oils, dirt, or contaminants.
- Primer Application: A corrosion-resistant primer is applied to improve adhesion and protect the metal from moisture and rust.
- Color Coating: High-performance color coatings are applied evenly across the steel. The color can range from earth tones to bright, modern colors, depending on the project’s needs.
- Baking and Curing: The coated steel passes through an oven at around 400 degrees Fahrenheit, baking the paint onto the surface. This creates a hard, durable finish that won’t peel or chip easily.
- Optional Protective Films: Some panels are shipped with a removable plastic film to protect the surface during transportation and installation.
Types of Finishes Available:
- Glossy Finish: High shine, modern appearance.
- Matte Finish: Soft, non-reflective look that’s popular for rustic or farmhouse styles. (looks great on a black barndominium)
- Textured Finish: Slightly rough to the touch, it provides extra depth and hides minor imperfections.
What to Look for in a Color Finish
When choosing a color and finish for your PBR siding, it’s essential to select a panel that features a high-quality paint system. The two most common types are:
- Kynar 500® (PVDF Coating): Known for superior fade resistance, chalk resistance, and long-term performance, especially in harsh climates.
- SMP (Silicone Modified Polyester): A durable, cost-effective option that still offers good color retention and protection.
Features and Benefits of PBR Siding for Barndominiums
Choosing PBR metal siding offers a strong combination of performance and appearance. Here’s a quick look at some of the key features and benefits:

| Ribbed Design | Adds structural strength and helps shed water quickly |
| Corrosion-Resistant Coatings | Protects against rust and extends the life of the siding |
| Wide Range of Color Options | Allows customization to match any barndominium style |
| Factory-Applied Finish | Superior durability with minimal maintenance required |
| Easy Installation | Panels overlap neatly, reducing labor time and costs |
| Low Maintenance | No regular painting, staining, or sealing needed |
| Long-Term Value | Durable siding that helps maintain property value over time |
Choosing the Right Siding for Your Barndominium
When it comes to selecting the perfect siding for your barndominium, there are a few key factors to consider. Understanding your needs and priorities will help you choose the best option for long-term satisfaction.
1. Climate and Weather Conditions
If you live in an area with high winds, heavy snow, intense sun, or frequent rainstorms, durability should be your top priority. PBR metal siding is an excellent choice because of its strength and resistance to the elements.
2. Desired Appearance
Think about the look you want for your home. PBR siding offers a clean, bold appearance and comes in a variety of colors and finishes, from rustic matte tones to bright, modern hues. Whether you want a traditional farmhouse look or a sleek, contemporary design, PBR panels can match your style.
3. Maintenance Expectations
If you prefer low-maintenance materials that don’t require constant upkeep, PBR siding is hard to beat. Unlike wood siding, it won’t need repainting, staining, or sealing year after year.
4. Budget and Long-Term Value
While metal siding may have a slightly higher upfront cost than basic vinyl, it delivers significant long-term value by lasting decades with minimal repairs or replacements. It’s a smart investment if you’re thinking about total cost of ownership over 20+ years.
5. Energy Efficiency Considerations
Adding insulation beneath your PBR siding can improve your home’s energy efficiency. Many barndominium builders pair metal siding with spray foam insulation or rigid foam panels for maximum performance.
- ✔️ Do you want siding that can handle high winds, rain, snow, or intense sun without constant repairs?
- ✔️ Are you looking for a low-maintenance option that doesn’t require frequent painting or sealing?
- ✔️ Do you prefer a strong, clean-lined look that fits modern, rustic, or industrial designs?
- ✔️ Is long-term value and durability more important to you than just the lowest upfront cost?
- ✔️ Would you like a wide range of color and finish options to match your barndominium style?
If you answered “yes” to most of these questions, PBR metal siding could be the perfect fit for your project.
Ask About Warranty and Coating Type
When comparing siding options, always ask about the type of paint coating (Kynar 500® vs. SMP) and warranty coverage. A good warranty often signals a higher-quality finish that will protect your investment for decades.
Final Thoughts
PBR metal siding combines the rugged strength of steel with the versatility of modern color options. Thanks to its ribbed design, long-lasting finishes, and easy maintenance, it’s an ideal choice for anyone who wants a building that stands the test of time and looks good doing it.
