What you should know
Before you negotiate a Ironworker offer in St. Louis, understand the terrain. St. Louis offers one of the most affordable major metro areas in the country, with a strong base in healthcare, financial services, and manufacturing. The region's anchor employers include Boeing, Centene, and Washington University's medical campus. A growing biotech and plant sciences corridor centered on the Cortex Innovation District is attracting new investment and talent. Structural ironworkers on high-rise projects earn the most due to height premiums and physical risk factors. Welding certifications combined with ironworking skills add 15 to 20% to base rates. Union ironworkers in major cities like New York, Chicago, and San Francisco see the strongest wage floors, with journeyman rates exceeding $45 per hour.
Ironworker apprentices start at $34,000 to $42,000 during their three to four year training period. Journeyman ironworkers earn $48,000 to $70,000, while foremen and superintendents reach $72,000 to $95,000. Project managers with ironworking backgrounds earn $90,000 to $125,000 at large structural contractors. In St. Louis, cost of living sits near the national average, so the numbers you see are roughly what you keep.
Base salary is not the full picture. Union benefits add $18,000 to $28,000 annually including health insurance, pension, annuity, and training fund contributions. Hazard pay for bridge, high-rise, or demolition work can add $2 to $8 per hour on top of base journeyman rates. And on the tax side: missouri's top income tax rate is about 4.8%, and St. Louis City adds a 1% earnings tax. The low base cost of living means your after tax salary still stretches further than in most metros. When someone quotes you $57,000, ask what the total package looks like. The gap between base and total comp is where real money hides.

The range for Ironworkers in St. Louis runs from $43,000 to $74,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
