Industry overview
Fabricated Plate Work (Boiler Shops) under SIC 3443 covers manufacturers of custom pressure vessels, heat exchangers, industrial boilers, storage tanks, and related piping modules for power generation, petrochemical, refining, utility, and large manufacturing clients that need high-integrity thermal and pressure systems. Companies engineer, weld, and assemble heavy plate steel with in-house testing, field installation, and lifecycle maintenance services to meet ASME Section VIII and Section I codes, National Board registration, and OSHA and EPA compliance, while managing risks from commodity steel volatility, complex welding quality control, and long-lead supply chains. In 2024-2025, demand is shaped by grid upgrades, LNG and petrochemical expansions, hydrogen-ready boilers, carbon capture and waste-heat recovery projects, plus growing use of modular skids, robotic welding, digital twins, and predictive monitoring. Owners also face tighter emissions standards and buy-American procurement preferences. For real-time corporate moves and capex disclosures, view live SEC filings on Earnings Feed.
