ASC Building Products Delta Rib 2022 roof profile

ASC Building Products Delta Rib is a named, light-gauge, exposed-fastener metal roof and siding panel with 24 inches of net installed coverage. Its current product offer lists 29- and 26-gauge metal, a minimum 3:12 roof slope, and custom manufactured lengths from 4 feet 6 inches to 40 feet. Delta Rib III is the maker's separate 36-inch configuration. State the full product name and 24-inch cover on an order inquiry; a three-foot Delta Rib III sheet is not a substitute for a two-foot Delta Rib roof, even where the paint finish looks similar.

This record uses ASC Profiles' Delta Rib Sales Print dated September 16, 2022 as its geometric identity. The maker's August 2025 PS223 sheet supports the later named metal product and its roof application, while the June 2026 installation guide shows Delta Rib among the light-gauge roof panels. These dates describe different documents, not three measured generations of the same roll-former. A replacement team can use the published section to recognize the profile, then compare the two actual free edges of a sound retained roof panel before ordering sheets for an older building.

The September 2022 Sales Print prints 24 inches of coverage across the lapped panel and eight inches between the main raised ribs. A shallow bead falls four inches from a main rib station, midway in each eight-inch module. The large rib is shown 13/16 inch high, with a localized 5/8-inch crest flat and a 2 1/2-inch base footprint measured between its feet. The angled main rib web is marked 40 degrees. The small bead has a localized 3/4-inch crest flat and 1 1/8-inch base footprint. These local arrows describe different parts of the section and should remain separately labeled in a fabrication inquiry.

The print explicitly marks its dimensions approximate. It does not give a numeric rise for the shallow bead, a complete loose-sheet width, both terminal return lengths, bend radii or forming tolerances. The visible 40-degree arrow belongs to the main web and cannot be copied onto the shallow bead or overlap. Likewise, 24-inch net cover is the installed distance produced by nested panels, not the strip width entering a roll former. Ask a sheet supplier to annotate a measured cross-section from the existing full-width panel, including both outer edges, before treating the published dimensions as a fit specification.

ASC's Delta Rib offer names 29- and 26-gauge steel, Dura Tech xl painted finishes and an unpainted ZINCALUME Plus finish. Its PS223 sheet lists separate base-steel thicknesses of 0.0139 inch for 29 gauge and 0.0173 inch for 26 gauge. Those values belong to the product sheet's steel properties; they do not identify the thickness of a particular roof already installed in Texas. Record any retained purchase documents, coating label and measured sample before requesting an apparent like-for-like piece. A color name alone cannot establish substrate, gauge or the weather face of a decades-old roof.

Mark the exterior painted face on the physical sample and on every cross-section photograph. Measure finished run length along the ribs, and distinguish a single full-length sheet from a roof with an end lap. PS223's load table addresses steel Delta Rib under its stated span and loading conditions; it is not a material schedule for custom fiberglass. If the intended finish is unavailable in the required gauge or production location, ask the metal supplier to state the proposed coated-steel specification and provide a current color sample. Keep that material decision separate from the two-edge profile fit check.

Delta Rib's manufacturer product page gives a 3:12 minimum roof slope. The June 2026 light-gauge guide covers use over a continuous rigid substrate such as plywood or OSB and over spaced supports, with different roof-preparation details. Before counting replacement panels, map the actual roof plane: roof slope, eave-to-ridge run, support type, support spacing, underlayment, number of full sheets and the side from which the original run was laid. Photograph the eave, gable, ridge, valley and each curb or pipe that intersects a Delta Rib panel. A profile order needs these positions as well as the section drawing.

ASC's guide depicts Delta Rib as the 24-inch-cover member in its fastening and prevailing-weather sheeting-direction diagram. It directs panels to lap away from prevailing weather and shows roof side-lap treatment. The appendix shows a six-inch minimum metal-panel end lap for the detailed long-panel condition. A local repair cannot choose an end-lap length from the 24-inch cover or the eight-inch rib module. Document the existing end-lap condition and the length of every replacement sheet, then coordinate it with flashing, closure, support and attachment work. The built-up metal roof installation service covers these surrounding roof-system interfaces.

The 2022 drawing shows a repeated central pattern and shaped outer ends, but its arrows do not form a complete numeric schedule for either loose free edge. A narrow one-rib cutout preserves the 40-degree web but loses the underlapping and overlapping legs that determine whether a new sheet seats beside retained panels. Set aside a sound full-width offcut or removable sheet when practical. Label left and right as seen from the eave, mark the exterior face, and identify which edge passes above its neighbor. Photograph the cut section square-on with a ruler in the same plane and measure loose width separately from the resulting installed cover.

Compare a short formed sample with the retained roof before committing to long lengths. Check that the main ribs arrive at eight-inch centers, that the shallow beads align halfway between them, and that the major rib height clears the adjoining panel as expected. Inspect both nested ends, including the contact line and any visible gap where water could enter. A generic 24-inch exposed-fastener panel can repeat at the same spacing yet still have a different terminal fold. Save the accepted cross-section, two-edge trial photographs and the supplier's finished-section drawing with the order record for the next repair.

Send the September 2022 ASC Sales Print, the August 2025 PS223 sheet and this page's one-page ordering PDF with a labeled full-width roof sample. State the printed 24-inch installed cover, eight-inch main-rib pitch, four-inch half-module bead position, 13/16-inch main rise, 40-degree main web, 5/8-inch main crest, 2 1/2-inch main base, 3/4-inch shallow crest and 1 1/8-inch shallow base. Identify those as approximate printed values. Add the measured actual free edges, loose width and weather-face orientation from the building rather than filling gaps in ASC's diagram with calculated tooling dimensions.

For each roof area, list quantity, finished sheet length, gauge, proposed metal coating, finish, roof slope, delivery location and required sequence of installation. Tell the shop whether it is sourcing current ASC material, matching a historic retained run, or evaluating custom rolling. Ask for a proposed section drawing and a short trial sheet that laps on both sides with the retained roof. The section approval should distinguish an actual ASC Delta Rib purchase from an alternative profile intended to fit its roof; it should also record any different valley, bead or edge detail visible on the trial.

The current ASC Delta Rib product sheet mentions matching polycarbonate skylight panels. Polycarbonate and glass-reinforced plastic are different materials, and the reviewed ASC sheets do not publish a Delta Rib GRP laminate section with both side laps. A GRP replacement inquiry should therefore describe a custom match to the actual roof, not an ASC stock fiberglass part. Send Dipcraft Manufacturing the original one-page ordering sheet, ASC's 2022 print and a full-width physical sample or square-on scaled images. Mark the weather face, two terminal edges, proposed daylight area, roof slope and intended installed cover.

Ask the GRP manufacturer to state the laminate and thickness it would offer, available lengths, its formed-section drawing and how a trial piece would sit against steel Delta Rib on both sides. Record the proposed support and fixing details for that fiberglass sheet instead of carrying over PS223's steel load table. The shallow beads, 40-degree main web and major rib rise establish central shape targets, but the undocumented free edges still control a mixed-material lap. A trial joint between the proposed GRP and retained metal supplies the practical comparison that a catalog picture cannot show.

For a fiberglass match, request a profile review from Dipcraft Manufacturing custom fiberglass roof-panel inquiry.

Five Texas metal businesses in separate regions can receive the same Delta Rib quote packet: Metal Warehouse in Sherman, Xtreme Metals near Flint and Tyler, Quality Metals in San Antonio, Lucid Metal Works in Houston and All Precision Metals in El Paso. Their panel or fabrication work makes them useful first contacts for an exact-material sourcing or custom-forming discussion. Send each the ASC documents, one-page summary, labeled 24-inch-cover roof sample, both side-edge photographs, finish and gauge request, finished lengths, quantities and delivery ZIP. Ask whether the shop can obtain named ASC Delta Rib, compare its existing tooling or arrange a sample-forming run.

Evaluate each reply on the cross-section it proposes rather than on the broad term ribbed panel. Request the loose width, net installed cover after overlap, main-rib and shallow-bead spacing, both shaped terminal edges and the offered metal thickness. Ask how the supplier will test a short section between retained roof sheets before producing all lengths. A quote for an ordinary R-panel or three-foot Delta Rib III does not describe this two-foot Delta Rib geometry. These five firms are feasible regional inquiry points; their possession of ASC's specific 2022 roll-forming die is not established by their general panel catalogs.

File the manufacturer one-sheet under its printed September 16, 2022 date and unnumbered revision row. Keep the PS223 product sheet under its August 2025 issue code and the light-gauge roof guide under its June 2026 BR128 code. The sales print supplies the 40-degree section callout; the later sheet identifies the marketed metal panel and its gauge and finish choices; the guide depicts the 24-inch Delta Rib roof installation among the ASC light-gauge family. The site photograph shows ASC's named Delta Rib Farmhouse project, while the manufacturer's gallery classifies that project as siding. It is a physical project view, not a measurement of this dated section.

Place the local one-page profile sheet beside the official documents and attach the metal shop's proposed section, GRP maker's distinct proposed section if requested, a labeled full-width old panel sample and photographs of each trial lap. Note the roof's sheet run, measured cover, support locations and material decision. Future repairs can then distinguish 24-inch Delta Rib from 36-inch Delta Rib III and can see which formed edges actually joined the retained roof. The printed central dimensions support the request, while the accepted physical sample and final supplier drawing record the sheet that was ordered.
