Specifications

What is R-Panel (PBR Panel)?

R-Panel and PBR Panel are the same profile — PBR (Purlin-Bearing R-Panel) is the modern industry name for what’s commonly still called R-Panel in the field. 36″ cover width, 1¼” major ribs spaced 12″ on-center, and a purlin-bearing leg so the panel works as roofing OR siding. Our R-Panel is 26-gauge Grade 80 steel — the contractor standard for residential roofs, carports, barns, barndominiums, and commercial roofs across Houston and Southeast Texas.

Why Polar White

Polar White is the bright, cool, reflective roof — the panel commercial buyers spec for energy performance, the panel residential builders use when they want a clean modern white roof, and the panel that pairs cleanly with almost any wall color. It’s the brightest panel we stock and reflects the most solar heat — a meaningful difference on a hot Houston attic. Common applications: warehouses, ag buildings with livestock cooling needs, commercial roofs targeting Energy Star or cool-roof credit, and residential builds focused on lowering attic temperature.

SMP paint — what it actually is

Silicone-Modified Polyester (SMP) is the contractor-standard mid-tier coil paint. It handles UV exposure, heat cycling, and Gulf Coast humidity — the three things a Houston roof actually deals with. The Sherwin-Williams WeatherXL system carries a 40-year chip/peel warranty and 30-year fade/chalk warranty out of the box. Important on a white panel where chalking would show first — SMP holds color longer than budget paints.

FAQ

What’s the difference between 26-gauge and 29-gauge?
26-gauge is 0.0185″ thick — the contractor standard for Houston roofing. 29-gauge is thinner (~0.0142″) and used on cheap residential jobs. For Gulf Coast hail and wind, 26-gauge is the floor.

Will my Polar White color match if I come back for more later?
We run from a single mill coil per color. Color batches can drift slightly between mill runs (industry-wide reality). For perfect match, buy all you need in one trip — we cut to your exact list. If you’ll need touch-up later, grab the batch tag stamped on your coil end before you leave.

Is “same-day cut” really same-day?
For orders up to about 2,000 linear feet of stock colors, yes — call with your footage, drive over, we cut while you load. Bigger orders may need 24 hours to schedule the shear clean.

Do you deliver?
Yes. Pickup is free at our Houston yard; delivery is available across the Houston metro and most of Southeast Texas (free on orders $1,500+). Call (281) 902-7619 for a delivery quote.
