Structural Iron & Steel Workers Salary in Washington

Structural iron and steel workers in Washington earn a median salary of $105,970 annually, or $50.95 per hour—significantly higher than the national median of $62,700. Entry-level workers (10th percentile) start around $55,340, while experienced professionals (90th percentile) can earn up to $125,350. Pay varies based on experience level, union membership, and location within the state. Seattle's booming construction market and major infrastructure projects drive strong demand for ironworkers. Union membership through locals affiliated with the International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers typically provides better wages, benefits, and job security. The 25th to 75th percentile range ($80,670 to $116,930) shows steady earning progression with experience. Washington's cost of living is 7.3% above the national average, making the cost-of-living-adjusted salary $98,760—still well above national standards. The state's robust construction industry, including high-rise development, bridge projects, and industrial facilities, creates consistent opportunities for skilled ironworkers.

In Washington, most structural iron and steel workers enter through a 3-4 year union apprenticeship program. The Washington State apprenticeship system is well-established, with programs offered through locals of the International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers. Major locals include Local 86 (Seattle) and Local 14 (Spokane). Apprentices typically start at 40-50% of journeyman wages and receive regular increases, reaching full scale upon completion. The program combines classroom instruction covering blueprint reading, welding, rigging, and safety with hands-on field training on actual construction sites. Most programs require a high school diploma or equivalent, with preference given to applicants with construction experience or technical training. Physical fitness and comfort with heights are essential. Washington doesn't require specific state licensing for ironworkers, but OSHA 10 or 30-hour safety certification is typically mandatory. Some specialties like welding may require additional certifications. The state's Department of Labor & Industries oversees apprenticeship standards. With approximately 580 apprenticeship programs nationwide and strong union presence in Washington, opportunities exist but competition can be intense. Community colleges offer pre-apprenticeship programs that can provide an advantage.

The $70,010 gap between the 10th percentile ($55,340) and 90th percentile ($125,350) primarily reflects experience and specialization differences. Entry-level ironworkers typically start as apprentices earning 40-60% of journeyman rates, explaining the lower 10th percentile. The jump from 25th percentile ($80,670) to median ($105,970) often occurs when workers complete apprenticeships and achieve journeyman status. Top earners (75th-90th percentile, $116,930-$125,350) are typically foremen, those with specialized skills like complex welding or rigging, or workers on high-profile projects requiring premium rates. Union membership significantly impacts earnings—union ironworkers generally earn more than non-union counterparts. Geographic location matters too: Seattle-area workers typically out-earn those in smaller markets due to higher prevailing wages and more complex projects. Overtime opportunities, common in construction, can substantially boost annual earnings for workers in all percentiles.
