Count Every Bar, from the Bundler to the Truck

Add a real-time count to every bundle leaving the line with Roboflow vision AI for rebar bundle counting. Built for rebar and merchant bar mills, fabricators, and service centers where bundles are counted by hand at the end face, a short bundle becomes a customer claim, and an over-count gives steel away.

Count from the end face:

Count every bar in a bundle from one image of the end face, with a model trained on your own bar sizes and bundle shapes.
Count tightly packed bundles of small bars by splitting high-resolution images into tiles with SAHI.
Mark each counted bar on the image, so the operator confirms the count at a glance.

Check against the order:

Compare each count to the bundle specification and order, next to count and quantity verification.
Read the bundle tag, heat number, size, and grade with industrial OCR.
Hold a short or over bundle at the bundler through the PLC for a recount.

Ship and trace:

Save an image and count for every bundle as evidence for customer claims and mill test certificates.
Count bundles loaded per truck or railcar against the shipping list.
Check straps and tags at the same station with bundle strap inspection.

Bring intelligence to every bundle today. Stop miscounts from becoming short shipments, customer claims, and steel given away.

Frequently asked questions

What is rebar bundle counting with Vision AI?

Rebar bundle counting with Vision AI uses a fixed camera at the bundler or shipping bay, or a phone or tablet in the yard, and a trained computer vision model (opens in a new tab) to count every bar from the end face of a bundle, read the bundle tag, and compare the count to the order. It pairs with billet tracking, pipe counting and tracking, and steel coil identification and tracking.

Can Vision AI count bars in a tightly packed bundle?

Yes. A detection model trained on your own end-face images finds each bar end, including small bars packed tight and ends that sit back from the face, and marks each one on the image. High-resolution images can be split into tiles so small bar ends stay large enough to detect, and the count comes back in seconds for the operator to confirm.

Does rebar bundle counting support ASTM A615, EN 10204, and ISO 9001?

Rebar bundle counting supports the identification and traceability expected under ASTM A615 and A706 (the standards for carbon and low-alloy steel reinforcing bar), EN 10204 (the standard for metallic product inspection documents, including mill test certificates), and ISO 9001 (the quality management system standard), with an image and count record for every bundle shipped.

Roboflow serves as the counting engine, and your quality and shipping teams own the bundle specifications and the response to a miscount.

Can it integrate with our bundler, MES, and shipping systems?

Yes. Roboflow writes the count and pass/fail to a PLC tag over OPC UA or MQTT, so the bundler can hold a bundle, and sends counts, tag reads, and images over REST (opens in a new tab) or to a database for MES, ERP, and shipping systems. Phone and tablet counts sync to the same record as fixed-camera counts.
