When planning a post-frame building, a major concern our clients have is how long it will last. Our buildings have consistently held up for many decades thanks to high quality building materials. Steel is like your post-frame building’s armor, shielding your investment from weather extremes and heavy use. That’s exactly why steel matters in your post-frame building. That said, not all steel is equal.
Premium Steel Panels: Proven Results
Meyer Building uses steel panels from McElroy Metal, a leading post-frame steel manufacturer in the nation. Backed by a non-prorated and labor-inclusive warranty, their 29-gauge, heat-treated, full-hard, high-tensile steel has a minimum yield strength of 80,000 PSI for high-strength resilience and dent resistance.
We specify Silicone-Modified Polyester (SMP) as our standard steel panel paint system for post-frame applications. SMP paint delivers durable, long-term value with strong UV protection, scratch and weather resistance, and a broad palette of 34 fade-resistant colors to complement existing structures and brand palettes.
For customers who want maximum color hold and chalk resistance, Kynar 500® polyvinylidene fluoride (PVDF) paint is an available upgrade option. PVDF coatings keep gloss and hue longer in high-sun-exposure applications and help new additions perfectly match original buildings years later.
Why Steel Matters in a Post-Frame Building
When you hear terms like 29-gauge, heat-treated, or high-tensile steel, they may sound technical, but each one contributes directly to how your post-frame building performs and lasts.
29-Gauge Thickness
A 29-gauge panel strikes the right balance between strength, flexibility, and efficiency for most Midwest agricultural, commercial, and community uses. It’s thick enough to handle wind, impact, and everyday wear without adding unnecessary weight, making it a practical, cost-effective choice for many post-frame projects.
Meyer Building also offers 26-gauge steel as an upgrade option for customers who want added dent resistance, durability, and peace of mind in extra-demanding or unique use cases. In many Midwest post-frame applications, 29-gauge panels deliver the durability, weather protection, and clean appearance you need without added cost or weight.
Heat-Treated, Full-Hard Steel
Heat-treating and full-hard processing increase the hardness of the steel, which improves its rigidity and dent resistance. This means panels hold their shape better under load, stay straighter over time, and resist the small dings that can happen during installation or weather events.
High-Tensile Strength (80,000 PSI Minimum)
Tensile strength measures how much force a material can withstand before it deforms. At a minimum of 80,000 PSI, this high-tensile steel provides exceptional structural integrity and resistance to bending or warping under pressure, from heavy snow loads, wind gusts, and daily stress.
SMP (Silicone-Modified Polyester) Paint Coating
SMP coatings are Meyer Building’s preferred standard for post-frame steel paint. They offer a durable finish that resists scratching and weathering while providing strong UV protection. Though less fade-resistant than PVDF, SMP coatings still deliver excellent performance and long-term value in most climates.
Kynar 500® (PVDF) Paint Coating
Kynar 500® holds its gloss and hue even after years of sun exposure, so the building maintains a like-new appearance far longer than panels with standard paint systems. If future expansion is a possibility for your building down the line, we recommend Kynar 500® paint for consistency and uniformity between the original structure and the building addition.
Post-Frame Steel FAQs
What does steel gauge mean, anyway?
The gauge refers to the steel’s thickness, with lower numbers indicating thicker steel. Most post-frame builders will offer 29- or 26-gauge steel. It’s helpful to know that not all steel panels are equally constructed. Some suppliers’ steel panels are at at the thin end of the allowable range, and may include the paint layer in the measurement rather than just the steel substrate.
Does thicker steel automatically mean better quality?
Not necessarily. While thicker panels can add weight, the real indicator of quality is tensile strength—how much force the steel can take before it bends or dents. A well-made 29-gauge panel with high-tensile, heat-treated steel can outperform a thicker panel made from softer material.
What makes 29-gauge steel a good choice?
It’s engineered to balance strength and efficiency. 29-gauge panels are thick enough to stand up to wind, snow, and impact, but light enough to avoid putting stress on the framing system—ideal for large spans and agricultural or commercial applications.
How long do steel panels last?
With high-tensile, heat-treated steel and durable factory coatings, properly installed post-frame panels can last for decades. When maintained and kept free of debris, their strength and finish protect the structure far longer than many traditional materials.
Why focus on tensile strength instead of just gauge?
Tensile strength (measured in PSI) tells you how much pressure the steel can withstand before deforming. Our panels meet or exceed 80,000 PSI, which means they’re engineered to stay straighter and last longer under the demands of wind, snow, and temperature swings.
What kind of warranty protection is included?
The steel we use from McElroy Steel comes with a non-prorated, labor-inclusive warranty that covers both material performance and finish durability. We walk you through the details so you know exactly how your investment is protected from the start.
