Customization is king in the world of construction and steel structures — even as it relates to metal building panels. That’s right, not all metal building panels are created equal, and their differences span far beyond their final colors and finishes. Read on for a high-level overview of a few of our industry’s most popular panel options — what they are, what sets them apart and why you might choose one over another.
R Panel Options
R-type building panels, arguably the most common type in our industry, come in 36-inch lengths and are traditionally made of 26-gauge steel. They feature a corrugated or ribbed design where some ribs stand taller than others, and their enhanced strength make these panels the go-to option in the steel building and pre-engineered metal building (PEMB) industries. At the same time, these panels have become increasingly popular in the residential realm. R panels are common in both roofing and wall applications, and are considered an “exposed fastener system”. Their overlapping design makes repairs and replacements quick, easy and affordable.
M/U Panel Options
Another popular exposed fastener system is the M or U panel. Like the R panel, it comes in 36-inch lengths, and is commonly used for both metal building roofing and wall applications. While the M/U panel features a similar corrugated design, its ribs all sit at the same height. In addition, it’s most commonly made of 26-gauge steel, making it slightly less sturdy than the R panel. (It should be noted that M/U panels are still durable options.) These panels can also be the more economical option, depending on your supplier and market conditions. Repair and replacement work remains quick, easy and affordable, thanks to the panel’s overlapping design.
PBR/PBU Panel Options
Purlin bearing panels, better known as PBR or PBU panels, are virtually identical to their R- and U-type metal building counterparts. There is one main exception, however: These metal building panels feature a more pronounced overlap, adding not only to the panel’s overall strength, but creating a stronger barrier to keep moisture and similar elements outside where they belong. PBR/PBU panels are ideal for metal building roofing needs, but their rugged design would probably be a bit much for walls or siding.
