MBCI 7.2 Panel roof profile

MBCI's 7.2 Panel is a symmetrical, exposed-fastener steel profile offered for roofs and walls. Five principal rib modules create a stated 36-inch installed coverage, with the raised trapezoidal ribs spaced 7.2 inches on center. MBCI also presents the panel for canopies, carports and walkway covers, where its repeating ribs are visible from a distance. Name the maker as well as the profile when requesting a replacement: Western Rib and other 7.2-inch panels share a nominal module but have their own dated sections and side edges. The useful identity for this record is MBCI 7.2 Panel accompanied by its 2026 documents and a sample taken from the actual roof.

The official MBCI photograph on this page shows the product on the Camden Community Charter School roof screen. That architectural screen is clad with the 7.2 Panel; it is not a photograph of the building's water-shedding roof. It confirms the appearance and named product association, while the roof application comes from MBCI's product specifications and data sheet. The image cannot show whether two free metal sheet edges interlock or what the rib web angle measures. For an installed roof, photograph a sound full-width sheet end, the weather face and both factory side edges alongside the manufacturer drawing.

The 7.2 Panel cross-section in MBCI's Commercial / Industrial Rev P catalog marks 36 inches of installed coverage, 7.200 inches between corresponding high ribs and 1 1/2 inches from pan to rib top. It labels the illustrated crest and valley flats as 2.146 inches and marks a rib web at 45 degrees typical. The left terminal carries a separate 0.63-inch dimension. That number is a linear callout at the illustrated edge, not a 63-degree bend angle. Keeping the unit and arrow position with the number matters when a fabricator builds an order worksheet from a small catalog diagram. The five repeated 7.2-inch modules account for the published 36-inch coverage after assembly.

Coverage is the working width after neighboring sheets nest. It should not be treated as the panel's loose overall width or the unformed coil width. The Rev P catalog has a 39 1/8-inch sheet-width basis in its pricing notes, which is a separate catalog quantity, not a complete set of developed bend lengths. A replacement order still needs the physical loose width and both formed terminal shapes from a sound sample. The 2.146-inch arrows mark particular flats on the printed sketch; they do not define the full path of every crest and pan across the sheet. The 45-degree mark identifies the typical illustrated web rather than supplying all fold angles, radii, clearances and side-lap geometry.

MBCI's exact-product Rev E data sheet, marked May 2026, repeats the 36-inch cover, 7.2-inch rib spacing and 1 1/2-inch height, but prints 2.12 inches at its illustrated crest and valley flats. The Commercial / Industrial catalog marked Rev P/MS/0926 prints 2.146 inches at the corresponding illustrated flats and also shows the 45-degree typical web. The catalog footer says effective March 4, 2026 while its colophon identifies the September revision. These are two dated published representations of the named product. Give a shop both pages with their own revision marks instead of silently replacing the 2.12-inch number with 2.146 inches or assuming the different labels document a tooling change.

The drawings are compact sales and product sections rather than a complete die schedule. The later catalog adds a printed angle and terminal callout, yet neither sheet closes every free-edge return, radius or nesting clearance needed to reproduce a panel. Measure the actual roof sample perpendicular to the ribs at several sound locations, including the crest flat, valley flat, rise, pitch and both ends. Record whether the measured flat seems closer to either published value and ask MBCI or the proposed fabricator for a current full-size section if one is available. A trial piece fitted to retained roof sheets settles more about practical interchange than an undated generic 7.2-inch label.

MBCI lists the 7.2 Panel for roof and wall use, with a one-half-in-twelve minimum roof slope and exposed attachment. Its May 2026 data sheet identifies 24 gauge as standard and 29, 26 and 22 gauge as optional. The product page gives nominal panel lengths from five to 50 feet. Those published options help frame a current metal order, but an installed roof may contain a different gauge, finish or generation. Check the metal thickness and coating on an undamaged part of the existing sheet, then record the roof slope, support type and spacing, run direction, end-lap positions, trim intersections and roof openings. A quote for a short replacement must fit the actual support and closure conditions as well as the cross-section.

The 7.2 Panel's regular ribs are also used as wall cladding, and MBCI notes that wall orders are generally reverse rolled. Specify a roof-facing color side and the installed overlap hand so a wall-oriented reverse-roll sheet is not sent for a roof repair by mistake. At the roof, mark which factory edge overlays the next sheet and which is covered, and keep the direction of installation on the sample label. Survey eaves, ridges, rakes and penetrations before deciding finished lengths. For work that involves a larger roof field, the built-up metal roof installation service can use these measurements to connect the requested section with sheet layout, support and weathering details.

Start with the Rev E product data sheet, Rev P catalog section and this page's one-page dimensional PDF. Identify MBCI 7.2 Panel, 36-inch installed cover, 7.200-inch rib pitch, 1 1/2-inch rise, Rev P 2.146-inch illustrated flats, 45-degree typical web and 0.63-inch illustrated left terminal dimension. Write the Rev E 2.12-inch flat labels beside their own May 2026 document rather than blending the values. Add photographs of the field panel with a ruler in the same plane as the cross-section and an intact full-width sample if the building can spare one. Measure the loose sheet width, effective cover after two sheets nest, material thickness, both side-edge returns and the position of any damage or earlier repairs.

List quantities and finished lengths by roof slope or building area, requested gauge, metal substrate or coating, exposed finish and color, delivery point and whether the new panel must lap existing MBCI material on one edge or both. Ask the supplier whether it will source an MBCI panel, use another roll set or investigate a special forming route. Request its proposed cross-section with both terminal edges, calculated cover and any departure from either dated MBCI sketch. Approve a short trial piece only after it seats against the surviving roof material at the actual side lap and support. A dimensionally similar 7.2-inch panel from another maker may still fail at the small over- and underlap bends.

MBCI separately lists a 7.2 Panel Light Transmitting Panel, part HW-1528, as a high-strength white fiberglass sheet. The Rev P catalog and the manufacturer's ordering page identify it as a 12-foot Type 1 panel with eight-ounce reinforcement and a listed weight of 19 pounds each. This is an exact-name route for a translucent GRP or fiberglass inquiry, separate from the steel sheet sold in multiple gauges. Give MBCI the proposed roof position, desired daylight opening, finished length, support spacing, roof slope and the intact metal field sample. Ask for the current fiberglass formed-section drawing and product-specific support, fixing and joint details for the intended roof location.

The metal Rev E data sheet and Rev P section describe steel-panel geometry; neither gives every dimension of the HW-1528 fiberglass free edges. Obtain a short fiberglass sample or dimensioned section and fit it between the roof's surviving metal on both sides, measuring rib height, pan contact, overlap direction and resulting coverage. If the requested GRP sheet must be opaque or must have a different length or laminate, put those requirements in the inquiry rather than treating the white light-transmitting listing as a custom-material quotation. Keep the GRP response separate from the Texas metal-shop quotes so the material, support schedule and actual formed shape remain clear on the order.

For a fiberglass match, request a profile review from MBCI 7.2 Panel Light Transmitting Panel — high-strength fiberglass HW-1528.

A measured MBCI 7.2 metal-sheet inquiry can be sent to five geographically separated Texas businesses: Metal Warehouse in Sherman, Xtreme Metals near Flint and Tyler, Quality Metals in the San Antonio area, Lucid Metal Works in Houston, and All Precision Metals in El Paso. Their published panel-forming or metal-fabrication work makes them useful feasibility contacts. The list does not establish that any owns MBCI 7.2 tooling. Send each the identical Rev P drawing, Rev E data sheet, one-page summary, full-width sample, roof photographs, lengths, quantity, gauge and finish. Ask whether it can supply genuine MBCI material, roll a measured compatible section or quote a special run after reviewing both side edges.

Compare responses against the same questions: what section and roll source will be used, what are its crest and valley flats, how will it handle the two published flat-width readings, and what cover results when a trial piece nests with the existing roof? Request a sketch of both proposed terminals and a short sample before a large order. Record any change in weather face, finish or reverse-roll orientation because the 7.2 Panel also has a wall application. These five contacts are for formed metal. The direct MBCI HW-1528 route handles the distinct fiberglass question; a metal shop's ability to quote a ribbed steel sheet is not evidence that it forms the matching GRP laminate.

Keep the manufacturer's May 2026 Rev E sheet, the September 2026 Rev P catalog, this single-page order summary and an accepted physical offcut together. Label the 2.12-inch and 2.146-inch illustrated flats by document date. Add photographs of the weather face, both uncut factory edges and a measured cross-section, plus a roof sketch marking slope, support lines, fastener pattern, sheet direction and locations of earlier repairs. Identify which numbers were copied from MBCI's drawings and which were measured from the particular building. If the supplier makes a trial panel, retain its section trace and the result of fitting it to both neighboring roof sheets.

The MBCI Camden image helps identify the broad 7.2 rib pattern, but it records a roof screen rather than a weathering roof joint. The roof-use specification and two dated section sketches establish the published metal profile; the actual roof sample establishes which historic or current edge details are in place. Keep any later manufacturer revision as a new dated document rather than overwriting the Rev E and Rev P values. If a fiberglass rooflight is commissioned, file its own formed-section drawing and trial-lap result with the metal record. That combination lets a future owner request a specific replacement in steel or GRP without relying on the generic words 7.2 panel alone.
