Metal Roofing Panel Guide: Types, Gauges & Applications

Choosing the right metal roofing panel depends on the building type, budget, and desired lifespan. LCA Metal Components manufactures and supplies a full range of steel roofing panels for commercial, agricultural, and residential structures throughout Riverside County and Southern California, including PBR, L5, U-Panel, 7.2 corrugated, 7.8 corrugated, B-Deck, and Spanish tile profiles.

PBR panels are the most widely used profile in metal building construction, featuring a major rib every 12 inches for strength and a clean, industrial look. L5 panels offer a lower, tighter rib pattern suited for both roofing and wall applications, while U-Panels provide a versatile, economical option for standing seam style installations.

Corrugated 7.2 and 7.8 panels are popular for agricultural buildings, barns, and pole structures thanks to their classic wave profile and durability, and B-Deck panels are engineered for structural decking in commercial roofs and floors. For a decorative touch, our Spanish tile panels replicate the look of clay tile roofing at a fraction of the weight and cost.

Panel gauge — typically 24, 26, or 29 gauge — determines thickness and load capacity, with lower gauge numbers indicating thicker, stronger steel. All panels are available in Galvalume or a painted finish using our LCA Metals Signature coating, which resists fading, chalking, and corrosion in Southern California's sun and heat. Minimum roof slope requirements vary by profile, so it's important to match the panel to your building's pitch.

Every panel is cut to length and shipped with contractor pricing and fast delivery across Riverside County, the Inland Empire, and the Coachella Valley. Contact our team for a free quote and expert guidance on selecting the right panel, gauge, and coating for your project.
