Ajin USA’s Joon Georgia EV Plant is a large-format industrial facility in Georgia — a 1,106 ft × 800 ft battery-stamping plant with distinct Press and Office areas. Moldtek handled the industrial steel detailing scope: 1,932 tons of main and secondary steel plus a high volume of panel embeds, broken into 135 detailing and erection sequences so the plant could be modeled, reviewed, and released package by package. The engagement ran fast-track on a compressed 15-week schedule and produced 225 erection drawings, with the steel continuously coordinated against precast, panel, joist, and mechanical trades via our structural steel detailing team.

The complication on the Joon Georgia EV Plant was never a single tall structure. It was scale, on the clock — a 1,106 × 800 ft industrial plant, a large volume of panel embeds, and continuous coordination with precast, panel, joist, and mechanical systems, all compressed into a 15-week fast-track programme.

A large quantity of panel embeds had to be detailed and integrated, each one an interface between the steel and the enclosure system.
Trade conditions required close, continuous alignment with the precast and panel teams so embed locations and framing matched.
Joist-package interfaces influenced sequencing and framing decisions, so the steel couldn’t be finalized in isolation.
Mechanical routing and equipment requirements fed directly into the detailing coordination.
A 225-drawing erection package demanded structured QA/QC and strict release discipline to stay on schedule.

The facility was divided into 135 detailing and erection sequences across the Press and Office zones — the single decision that kept a fast-track programme controllable.
Main steel, secondary steel, and panel embeds were detailed inside that sequenced structure, so each trade interface was resolved in a controlled order rather than all at once at the end.
Interfaces with the precast, panel, joist, and mechanical trades were coordinated and clashes resolved sequence by sequence.
Erection drawings and reports were quality-checked before release, keeping 225 drawings moving through review without becoming a bottleneck.
Because the model was sequenced into 135 packages, detailing progress stayed visible sequence by sequence — the client could see exactly what was modeled, checked, and ready for release at any point across the 15 weeks.
The plant was detailed on Moldtek’s standard toolchain and delivered against US structural codes, so fabrication, erection, and multi-trade coordination all worked from the same clean release.
Model clarity and sequence discipline translated a high-volume industrial steel package into coordinated deliverables that support fabrication, erection planning, and multi-trade coordination.
A clear breakdown of a high-volume industrial steel package, released package by package.
Improved visibility into fabrication and erection drawing progress across every sequence.
Precast, panel, joist and mechanical interfaces resolved without stalling the release.
