Slagworks Industrial

number	34
name	Slagworks Industrial
full legal name	Slagworks Industrial Fabrication & Heavy Materials Corponation
common names	Slagworks The Slag Ironmouth Works
stock designation	SLGW-IND
sector	Heavy Manufacturing / Industrial Fabrication / Reclamation Metallurgy
valuation	₩478 billion
revenue	₩112 billion annually
employees	318,000 (direct); ~500,000 (contracted fab labor across partner facilities)
sovereign territory	The Slagworks Foundry Belt — a continuous sovereign industrial zone spanning 34 kilometers along the southern Lake Michigan shoreline, incorporating the former industrial infrastructure of Gary, Hammond, and East Chicago, Indiana. The zone is one of the most heavily polluted sovereign territories in the corridor, a fact Slagworks considers an operational feature rather than a liability.
founding story	Slagworks was assembled rather than founded — a corporate consolidation event in 2136 in which a private equity consortium acquired seventeen failing Rust Belt steel, fabrication, and reclamation operations and merged them under a single sovereign charter. The driving figure was Benedikt Mrak, a Croatian-American industrial financier who believed the corridor's coming infrastructure boom would create insatiable demand for structural materials and that the only way to meet that demand was vertical integration at massive scale. Mrak was right. As Palladian Construction, Ferrogate Transit, and a dozen other infrastructure corponations exploded in the 2040s, Slagworks became the foundational supplier — the entity that made the steel that built the corridor. The corponation's sovereign territory was established in 2139, largely because no city-state wanted to claim jurisdiction over the environmental catastrophe that Slagworks' operations continued to generate. Mrak died in 2152 of heavy metal toxicity, a fact his corponation marked with a company-wide minute of silence and then immediately suppressed from public record.
security force	The Furnace Watch — 19,000 security and enforcement personnel, the largest corponation security force in the corridor outside the Big 20 defense specialists. The Furnace Watch is notorious for its aggressive response to labor actions: Slagworks has the highest rate of security-related worker injuries in the corridor, a distinction it has held for eleven consecutive years. The Watch also operates an industrial espionage division called the Tap, focused on protecting Slagworks' proprietary alloy formulations and reclamation processes.
key detail	Slagworks' Reclamation Metallurgy division is its most innovative and most controversial operation. The division processes structural debris from demolished buildings, decommissioned infrastructure, and — under contracts that other corponations prefer not to discuss publicly — wreckage from military and security operations across the corridor. This means Slagworks regularly receives and processes materials containing human remains, classified technology fragments, and chemically hazardous compounds. The corponation's sovereign status means no outside inspector has ever formally audited the Reclamation division's intake manifest.
relationship to big 20	Not currently a Big 20 member, though Slagworks supplies materials to at least 14 of the 20. This dependency gives Slagworks enormous informal leverage, and the corponation has used it — notably in 2158, when it briefly halted steel shipments to three Big 20 members during a sovereign border dispute, triggering a construction crisis across the corridor. Big 20 members have repeatedly discussed vertically integrating their own materials supply to reduce Slagworks dependency. None have succeeded in doing so at scale.
full text	SLAGWORKS INDUSTRIAL FABRICATION & HEAVY MATERIALS CORPONATION — The corridor's dominant heavy manufacturer and the entity whose steel, alloys, and fabricated components underpin the physical infrastructure of GLMZ itself, Slagworks operates from the Foundry Belt: a 34-kilometer sovereign industrial zone along Lake Michigan's southern shore, built atop the ruins and repurposed bones of Gary, Hammond, and East Chicago. Assembled in 2136 from seventeen failing Rust Belt operations by financier Benedikt Mrak — who died of heavy metal toxicity in 2152 — Slagworks grew to dominance by being indispensable: when the corridor's infrastructure boom arrived, Slagworks made the steel that built it. Annual revenues of ₩112 billion and a workforce of over 800,000 direct and contracted employees make it one of the corridor's largest employers, though labor conditions in the Foundry Belt are among the harshest documented anywhere in GLMZ. The Furnace Watch, 19,000 strong, enforces sovereignty and suppresses labor action with a consistency that has earned the corponation eleven consecutive years as the corridor's leader in security-related worker injuries. Slagworks' Reclamation Metallurgy division processes structural debris of every variety — including, under undisclosed contracts, military wreckage and materials containing human remains — with no outside audit authority ever having examined the intake manifests. Not a Big 20 member, but supplier to 14 of them, a leverage position Slagworks has demonstrated it will use. The Foundry Belt smells of sulfur and hot iron for thirty kilometers in every direction, and the smoke that rises from it is visible from the upper floors of Chicago's tallest towers — a permanent reminder of who built the world the corridor lives in.
