PBR-Panel roof profile

Metal Sales PBR-Panel is an exposed-fastened, trapezoidal metal sheet for commercial and industrial roofs and walls. This record describes the roof version documented by Metal Sales in its current technical reference and in the dated roof drawing behind Miami-Dade Notice of Acceptance 23-1214.05. PBR refers to a purlin-bearing rib: the side of one panel extends beneath the neighboring rib where the sheets overlap. That edge is important when an existing roof needs one replacement sheet or a new rooflight panel. A sheet can share the familiar 36-inch cover and 1 1/4-inch major rib while still have a different side-lap fold, crest width or web angle. Order against the named Metal Sales drawing and an existing panel sample, rather than the generic words R-panel alone.

The current Metal Sales reference describes a 36-inch net coverage width, major trapezoidal ribs at 12-inch centers and a 1 1/4-inch major rib rise. Two lower ribs appear between the major ribs at 4-inch spacing. The exterior painted face sits above the cross-section in the profile drawing. The 36-inch figure is the installed cover from one panel to the next; it does not state the flat coil width or the overall formed width before lapping. This distinction matters when requesting a replacement because an unmatched overlap can change both the visible coverage and how the sheets bear on a purlin.

The detailed Metal Sales roof drawing dated November 28, 2023 gives 36.0000 inches of effective cover and 12.0000 inches between major rib centers. The major crest flat measures 0.9895 inch, and the major rib base is dimensioned at 3.3021 inches. The web on the main trapezoidal rib is marked 47 degrees 14 minutes. Lower reinforcing ribs occur at 4.0000-inch intervals; their rise is 0.1875 inch, their base width is 0.7439 inch and their web angle is 28 degrees 36 minutes. These values identify the particular documented Metal Sales roof section more precisely than a catalogue silhouette. The one-page ordering sheet in the file section sets out the same dimensions in a portable format for a quote inquiry.

At the side lap, the inboard return is shown as 0.3800 inch. The overlap detail marks a 47-degree 31-minute return and a radius of R 0.0940 inch at the fold. The manufacturer drawing also distinguishes the outboard detail with a purlin-bearing leg from the no-bearing-leg detail. That difference should be checked against an undamaged piece from the roof before a replacement is accepted. A field sample should show the entire rib and both sides of the overlap, not only the roof's exposed top face. A photograph of the face helps identify the rib pattern, but the actual edge geometry determines whether a proposed sheet nests against the installed sheet.

Metal Sales lists 26- and 24-gauge steel as standard PBR-Panel offerings and 22 gauge as an option. The current technical reference names PVDF, MS Colorfast45 and acrylic-coated Galvalume finishes, along with unpainted Galvalume and galvanized corrosion-protection options. A replacement order should state the chosen metal, nominal gauge, coating and color separately from the cross-section. The geometry sheet identifies the shape; it does not choose the thickness or finish for a particular building. Record the existing panel length from eave to ridge or from the relevant end-lap line, the number of sheets, the panel direction, and whether the right or left edge has the purlin-bearing leg when viewed from the exterior face.

The 2026 Metal Sales sheet gives a five-foot minimum and a 45-foot recommended maximum panel length. Those numbers describe the manufacturer product range, while an individual roll-forming shop may have different handling or delivery limits. Include the job ZIP code and unloading constraints with a quote request. If the existing roof contains an end lap, measure where the sheet is supported and photograph the lap arrangement before taking material off the building. State whether the new sheet must match a single existing bay, continue across several purlins or form part of a larger replacement area. This helps the supplier price the correct length and lets the installer compare the proposed edge and end-lap arrangement with the roof being repaired.

A matching GRP sheet is a separate fiberglass product shaped to meet an existing metal roof profile. The Metal Sales PBR document describes a metal sheet; its steel gauge, load table and roof approvals do not describe a fiberglass replacement. A GRP quote should start with the same cross-section sheet and an undamaged metal sample, then state the required panel length, quantity, translucency or opacity, color, nominal laminate thickness and the roofing location. Ask the fiberglass fabricator to compare its available pattern library and tooling with the measured major ribs, minor ribs and both overlap edges. The lap should be checked on a physical trial piece before the full quantity is made.

Dipcraft Manufacturing is a US fiberglass-panel source that specifically invites sketches of existing corrugated metal panels and reviews custom shapes when the quantity and tooling allow it. It is based in Pennsylvania, not Texas. Its catalog of stocked patterns may give a quicker answer for a common rib, while a one-off Metal Sales lap may call for a separate tooling review. Provide the manufacturer's roof drawing as well as this one-page summary so the shop can see the fold and radius detail. For a rooflight or replacement zone, the inquiry should also identify the support spacing and intended daylight area; a visually similar translucent sheet is not automatically a structural equivalent of the metal panel it replaces.

For a fiberglass match, request a profile review from Dipcraft Manufacturing.

For a metal replacement, five regional Texas fabricators provide practical places to send the profile drawing. Metal Warehouse in Sherman advertises in-house PBR roll-forming to ordered lengths. Xtreme Metals in Flint, serving Tyler and East Texas, describes in-house R-panel production and cut-to-length service. Quality Metals lists PBR panels and roll-forming at its San Antonio facility. Houston-based Lucid Metal Works lists R-panel among its roofing metal profiles. All Precision Metals says it forms R-panel in El Paso and cuts sheets to ordered length. Each shop has a different equipment set, so ask it to compare the 2023 Metal Sales fold, web angles and side-lap hand with the sample before treating a quotation as a matching replacement.

Send the one-page sheet, the exact manufacturer roof drawing, clear photos of both panel faces and the removed sample measurements. A useful supplier reply identifies whether the shop has an existing die that reproduces the overlap, whether a special roll set would be needed, the gauges and finishes it can supply, the minimum quantity, and its practical transport length. If the job involves a GRP sheet, send the same package to a fiberglass specialist as a separate request. A Texas shop's metal R-panel offering does not establish that it can make fiberglass. Keeping the material requests separate also makes the resulting quotes easier to compare on geometry, thickness, finish and lead time.

Metal Sales presents PBR-Panel as an exposed-fastened metal building roof and wall system that can be installed over open framing or a solid substrate. Its current technical sheet states a 1:12 minimum roof slope. The roof drawing in the Miami-Dade notice depicts a specific approved assembly with defined support and attachment conditions; it is a reference for the documented cross-section, not a blanket approval of every gauge, support or replacement material. On an existing roof, record purlin spacing, support material and the location of any penetrations before specifying a sheet. The required fastening pattern and seals belong in the roof assembly design, while this profile page concentrates on sheet identity and ordering information.

When a larger roof area is being renewed, panel geometry should be reviewed alongside insulation, liner, spacer and weather-sheet choices. Total Cladding and Roofing's built-up metal roof installation service explains how those components can be coordinated for a Texas commercial building. A replacement sheet within an older roof may have a narrower scope, but the edge of that sheet still meets flashings, penetrations and adjoining roof sheets. Mark the replacement boundaries on a roof plan and retain a copy of the panel sample with the order. Future repairs are easier when the exact manufacturer, drawing date, metal thickness, finish and profile PDF travel with the building record.
