H-One/KTH’s $100M+ Seguin Plant Reaches Filed Construction Window
The automotive components investment now has an $87 million building registration, with physical mobilization still to be confirmed.
H-One/KTH Texas’s planned automotive structural-components plant in Seguin has entered its registered construction window, with the state filing listing October 1 as the scheduled start. A separate confirmation of crews mobilizing has not yet been established.
The project, announced in July, carries a commitment of at least $100 million across construction, machinery and equipment. The state registration identifies a narrower $87 million construction estimate near the northwest quadrant of I-10 and Highway 46.

A press shop with supporting offices
The filing totals 281,140 square feet: approximately 263,288 square feet of manufacturing space, a connecting two-story administration building of 17,542 square feet, and a 310-square-foot guardhouse. That is more specific than the approximately 300,000 square feet used in the original economic-development announcement.
The announced production plan includes three automated press lines, including a 3,500-ton press, with 170 jobs targeted by 2031.
Operating and construction targets differ
The original announcement targeted operations in April 2028, while the construction registration runs through October 31, 2028. Those dates may describe different milestones, but a phased handover has not been confirmed.
The project should therefore be tracked as entering its scheduled construction period, with a verified field start and a reconciled delivery timetable still to follow.
A 40-acre manufacturing investment
The City of Seguin’s July announcement places the development on 40 acres along FM 78, near I-10 and Highway 46. H-One is expanding through its North American subsidiary KTH Texas, adding a local production base for automotive structural components.
The planned press lines will work with ultra-high-strength steel and aluminum used in vehicle structures. That production description gives the investment a more specific identity than a general warehouse development: the building is intended to accommodate manufacturing equipment and associated material movement, as well as administration and employee facilities.
Equipment is a major part of the delivery story
The at-least-$100 million commitment includes machinery and equipment, while the state filing describes the construction scope. The difference between those figures should not be treated as a confirmed equipment budget, because the announcement uses a minimum investment commitment and the registration uses an estimate.
TCH’s delivery assessment is that completing the building and installing a production line are linked but separate tasks. The announced 3,500-ton press illustrates the scale of the manufacturing plan, but the sources do not disclose equipment-delivery dates, foundation specifications or a commissioning sequence. Those milestones would help explain how the plant moves from construction into production.
Employment builds over time
The 170-job target extends to 2031, several years beyond the initial operating target. It should be read as a hiring commitment over time rather than the workforce expected on the first day of production. A verified construction start and updated operating schedule will make it easier to track that transition.
