Price Rebar by Weight and Ship Every Heat With Its Mill Cert

You count pieces and bill pounds. A contractor orders 120 pieces of #5 at 20 feet. You price per hundredweight. Between the two sits each bar size's nominal weight per foot. Gerdau's straight rebar technical specifications list #3 at 0.376 lb/ft, #5 at 1.043 lb/ft and #18 at 13.6 lb/ft. So that order is 2,503 pounds before a single bend, about 25 hundredweight. A storefront that only knows "each" cannot show that number, and one that only knows weight cannot tell the yard how many sticks to pull.

The price per hundredweight has a shelf life. Steel reprices with its market. Monday's number may not hold for a pour three weeks out, and an open-ended quote hands the contractor a free option on your margin.

The fabricated order is a bar list, not a cart. The detailer turns the engineer's design into placing drawings and a bar list: bar mark, size, quantity, cut length, shape and leg dimensions. ACI PRC-315-18, the American Concrete Institute's Guide to Presenting Reinforcing Steel Design Details, guides designers on the information "required to prepare reinforcing steel fabrication details and placing drawings," so the detailer can present the design in a manner that is "clear and unambiguous to the reinforcing steel fabricator and placer." CRSI publishes a fabrication standard, IPG5.1, on bend diameters, measuring points and fabrication tolerances. A contractor holding a 400-line bar list has no reason to rebuild it bar by bar in a product grid.

The mill test report travels with the heat. Bars are rolled from heats of steel, and the heat number ties a bundle back to its test results. South Carolina DOT's reinforcing steel supplemental specification says "Each shipment of rebar delivered to the project must be accompanied by the manufacturer's mill test report for each heat included in the delivery." The report must show the "Heat number and size of rebar represented by the report", the grade and the tensile results. Under that specification, a truck carrying #4, #5 and #8 from three heats needs three reports, so the order has to record which heats are on the truck.

The grade comes from the specification. ASTM A615 covers "deformed and plain carbon-steel bars in cut lengths and coils for concrete reinforcement" in Grades 40, 60, 80 and 100. ASTM A706 covers low-alloy bars in Grades 60, 80 and 100, for applications where restrictive mechanical properties and chemical composition are required for controlled tensile properties or to enhance weldability. When the project specification names one, the order carries it and the mill test report proves it.

One project, many deliveries, and public work adds a domestic-content file. A building takes its rebar in loads: footings, slab on grade, then each deck and its columns, each landing when the crew is ready to place it. On federal-aid highway work, FHWA's Buy America rule at 23 CFR 635.410 states, in paragraph (b)(1)(ii), that "if iron or steel products are to be used, all manufacturing processes, including application of a coating, for these materials must occur in the United States." SCDOT's mill test report must also carry a "Statement ensuring that the steel was melted and manufactured in the United States". Coverage is a contract question. Your order system keeps the documents that answer it.

Weight pricing on a piece count. Uncap Quotes runs configure, price, quote inside the Shopify admin, with negotiated prices, tiers and volume breaks applied automatically. Pricing per hundredweight or ton, by size and grade, is configured during implementation on top of those account prices. Converting pieces and lengths to pounds by each size's nominal weight per foot is built during implementation. The buyer enters pieces and feet and sees pounds and the extended price on the same line. Calculated or scale weight on the invoice is your call.

Market-priced quotes that expire on a date. Quotes in Uncap Quotes carry a validity window and a full revision history, so a job price is tied to a date and every requote is on file. A price hold past your window goes to the right approver. Pricing and terms pull from the systems you already trust.

Bar lists in, priced quote out. The contractor or detailer uploads the bar list from the placing drawings instead of keying it. Import, validation against your standard shapes and weight extension per bar mark are built during implementation, on top of the CPQ workflow in Uncap Quotes. Cutting and bending charges sit on the quote as their own lines, because Uncap Portal lets a Shopify store "sell services and rentals alongside standard ecommerce products". When the contractor approves, the approved quote turns into a Shopify order in one click.

Heat numbers on the order, reports on the delivery. The ERP tracks stock by heat number. Heat-level availability, so the storefront only promises a quantity a single heat can fill and the order records which heat it ships from, is built during implementation on inventory synced through Uncap Connect. For rebar, the single-heat rule can be relaxed in the build, since under specifications like SCDOT's a delivery can carry several heats as long as each has its report. Attaching the mill test report for each heat on a delivery to that order, so the contractor and the inspector can pull it from order history, is built during implementation.

Releases by pour or by floor against one project. The project is quoted and approved once. Splitting it into releases, each tied to a pour or a floor with its own requested date, is built during implementation. Each release becomes its own Shopify order against the approved quote. In Uncap Portal, contractors get real multi-user accounts with roles and permissions, plus budgets, approvals and limits per user, so the project manager approves the release the foreman requested.

The Shopify question, answered on architecture. Uncap's published products do not include bar list import, weight extension by bar size or heat-to-delivery document tracking. On Shopify, those rules are built during implementation from your ERP data, so the real questions are where they live and whether your account data arrives intact. The integration to check is one that maps company accounts, catalogs and contract pricing into Shopify B2B. Uncap Connect runs inside Shopify rather than as separate middleware. Its real-time, two-way sync covers inventory, orders, customers and pricing, including customer-specific pricing, credit terms and tax rules. The ERP stays the system of record for heats, weights and price per hundredweight.

Buy America jobs flagged at the project. A project flag, built during implementation, limits its releases to heats whose mill test reports carry the domestic statement the owner requires and attaches those reports to each delivery. Whether a job is covered, and whether a heat qualifies, stays with your quality team and the owner.

Proof, labeled at its distance. No rebar or steel case study is published yet. The closest build is adjacent: ULE Group, "a leader in industrial and construction equipment, moved its million-SKU catalog onto a Shopify B2B storefront built by Uncap." Its build runs "a real-time Epicor ERP integration" that "syncs inventory and pricing."

Price per hundredweight or ton. Negotiated account prices applied automatically in Uncap Quotes, with pricing by weight, size and grade configured during implementation.

Pieces to pounds on every line. Pieces and lengths extended to pounds and hundredweight from the nominal weight per foot, built during implementation.

Bar list upload. Imported from the placing drawings, checked against your shapes and priced by bar mark, built during implementation.

Cutting and bending as line items. Fabrication charges sold as service lines next to the steel, through Uncap Portal.

Heat on the line, report on the truck. Each order records which heat it ships from, with the mill test report for each heat on the delivery attached, built during implementation.

Releases by pour or floor. One approved project quote, released in dated parts, each its own Shopify order, with the release structure built during implementation.

Quotes that expire. Validity windows, a full revision history and approval routing for price holds.

ERP sync. Pricing, inventory, customers and orders kept current with the ERP, through an owned Uncap Connect app embedded in Shopify, or a managed iPaaS integration.

The line between product and build, in writing. Account pricing, validity windows, approvals, one-click order conversion, company accounts and service lines ship in Uncap Quotes and Uncap Portal. Weight extension, bar list import, heat records, report attachment, releases and the Buy America flag are built during implementation. The scope shows which is which before the build starts.

Built on the records your ERP keeps. Where your ERP already holds heats, weights and prices per hundredweight, the build reads them instead of keeping a second copy in the storefront. What your ERP exposes is confirmed during scoping.

Credentials you can check. Uncap is a Shopify Platinum Partner, on Shopify since 2013, with 380+ unified storefronts launched on Shopify.

Scoped before it is built. The Uncap Blueprint is a fixed-price, four-week plan, credited 1:1 toward implementation. It covers solution architecture, data taxonomy, an ERP integration audit, UX and flow prototyping, total cost of ownership and a risk register, with a fixed-cost implementation estimate. For a rebar shop, that architecture work can cover weight pricing, bar list import and heat records. You walk with everything you need to brief any agency or your in-house team.

This page sits under construction supply ecommerce, which covers branch stock, will call and jobsite delivery, job accounts under contractor accounts, roles and approvals, and net terms. This page goes one level down, into steel priced by weight, fabricated to a bar list and certified by heat. Both sit within building and construction. If your yard also sells framing lumber, which reprices with its own market, see lumber and wood products. For submittals, spec sheets and job quotes with version history across dimensional products, see building materials. For quoting when each job prices differently, see the field notes on quote-to-order for construction supply. For the ERP side, see the Sage 300 integration, the Epicor Prophet 21 integration, or the full list of ERP integrations.

Bring two documents: a bar list from a recent job, and the mill test reports that shipped with its first delivery. Between them they hold your shapes, your weight math and your heat records.
