CSTM

What CSTM does

CSTM inc. is a privately held custom sheet metal fabrication company founded in 1988 and headquartered in Granby, Québec, Canada. The company manufactures complex custom-made sheet metal products in short series for innovative projects, serving four primary verticals: public transportation (trains, streetcars, buses, specialized vehicles), medical and paramedical equipment, instrumentation and data-acquisition electronics, and aerospace (embedded system components and brackets). It operates from a single manufacturing facility at 1105 boulevard Industriel, with a headcount range of 11-50 employees.

CSTM's core technology stack centers on CNC turret punching (Amada Vipros 255, Aries 245), CO2 laser cutting (Amada Lasmac LC-1212 at 2000 watts), and precision press brake bending using Amada Promecam equipment with 8-axis computer-controlled back gauges, achieving tolerances of ±0.002" to ±0.005". Services extend to mechanical assembly (PEM hardware, rivets, spot welding, Nelson stud welding) and surface treatment (plating, painting, anodizing, silkscreen, engraving) delivered through an established network of partner subcontractors. The company holds ISO 9001-2000 certification (2004), legacy ISO 9002 (1996), and the MACH 2 Performance Label from Aero Montréal (2015), qualifying it for aerospace-grade contract work.

Revenue is generated through project-based custom manufacturing contracts priced via quotes delivered within 16 hours of request, with no published standard pricing. Go-to-market is enterprise field sales targeting engineering and procurement teams at manufacturing firms in specialized industries, supported by a bilingual website and LinkedIn/Facebook corporate pages. Customer concentration spans four industry verticals with no named anchor accounts disclosed, and a single European partnership (Micheneau, France) suggests limited cross-border commercial reach beyond the Canadian market.

Expansion highlights4 records

Direct peers

• Mayville Engineering Company: Wisconsin-based contract manufacturer offering sheet metal fabrication, machining, and assemblies for aerospace, defense, and industrial customers. Directly comparable to CSTM in contract manufacturing model, multi-sector customer diversification, and short-to-medium run production focus.
• BTD Manufacturing: Minnesota-based custom sheet metal and metal fabrication services company serving aerospace, defense, medical, and industrial markets. Closely comparable to CSTM as a multi-sector contract sheet metal fabricator with similar equipment (laser, CNC punching, bending) and customer profile across regulated industries.
• Metaltek International: US-based custom metal casting and fabrication company serving industrial, aerospace, and defense markets. Comparable to CSTM in multi-sector custom metal manufacturing services and similar customer verticals, though Metaltek also includes casting capabilities CSTM does not have.

Broad incumbents

• Precision Castparts Corp: Large US-based manufacturer of complex metal components for aerospace, power, and industrial markets (a Berkshire Hathaway company). Broad incumbent in aerospace metal components with overlapping customer base to CSTM, though operating at vastly greater scale and with broader process capabilities.
• Spirit AeroSystems: World's largest tier-one aerostructures manufacturer producing fuselages, wing components, and propulsion systems for commercial and defense aerospace. Broad incumbent in aerospace metal fabrication with overlapping customer base to CSTM, but operating at orders-of-magnitude larger scale as a tier-one OEM supplier.

Regional players

• Héroux-Devtek: Longueuil, Quebec-based manufacturer of aerospace landing gear and components for commercial and defense markets. Comparable to CSTM as a Quebec-headquartered aerospace supplier in the same Aero Montréal cluster, though focused on large structural systems rather than sheet metal enclosures and brackets.
