Steel is one of the most versatile building materials in the industry but only when you’re using the right metal panel for the job. Every panel profile is engineered with a purpose, whether that’s shedding water on a low-slope roof, adding texture to an accent wall, or covering long structural spans with minimal support.
Understanding your options up front can save time on the jobsite and ensure long-term performance. Below, we’ll walk through the most common panel types used in roofing, siding, and beyond along with when and why to use each.
Concealed Fastener Panels: Clean, Sleek, and Weather-Resistant
Concealed fastener panels offer both function and form. Since the fasteners are hidden beneath the panel seams, you get a smoother, more modern appearance plus added protection from water intrusion and UV exposure.
Snap Lock Panels
- Best for: Residential and light commercial roofing
- Minimum slope: 3:12
- Why choose them: Snap together without mechanical seaming, offer crisp lines and fast installation
Mechanical Lock Panels
- Best for: Low-slope roofs, high-wind or storm-prone zones
- Key benefits: Strong seam engagement, suitable for slopes as low as 0.5:12 depending on spec
- Certifications to look for: UL 580 (uplift), UL 2218 (impact), and TDI-approved systems
These panels are often chosen for architectural projects where both performance and presentation are a top priority.
Exposed Fastener Panels: Efficient, Durable, and Cost-Effective
Exposed fastener systems are the go-to solution for fast, functional installs. You’ll see them on agricultural buildings, warehouses, and garages, as well as homes with a rustic or utilitarian aesthetic.
PBR Panel
- Best for: Roofing and siding on barns, shops, and commercial spaces
- Strengths: Deep ribs improve strength and water shedding, purlin-bearing leg supports better overlaps
U Panel
- Best for: Residential siding or garage/shop builds
- Strengths: Closer rib spacing gives a smoother appearance; blends better with residential finishes
7/8″ Corrugated Panel
- Best for: Accent walls, ceilings, custom interiors
- Strengths: Lightweight, visually bold, flexible for interior or exterior use
Exposed fastener panels are often easier to install, require fewer specialized tools, and can be cost-effective for large square footage.
Specialty Panels: More Than Just Roofing and Walls
In addition to the primary roofing and siding systems, specialty metal panels play important roles in modern builds.
Flush Wall & Soffit Panels
- Used in soffits, breezeways, porch ceilings, and accent walls
- Often vented to allow for air circulation under roof overhangs
- Provide a clean, seamless appearance—especially in commercial settings
- Ideal for privacy fencing and perimeter applications
- Durable, wind-resistant, and low maintenance
- Frequently used in both residential and commercial environments
These profiles are excellent for design consistency when you want the entire building envelope from roof to fence to feel unified.
