Structural Iron & Steel Workers Salary in Idaho

Structural iron and steel workers in Idaho earn a median salary of $62,190 annually, or $29.90 per hour. Entry-level workers (10th percentile) start around $50,220, while experienced workers (90th percentile) can earn up to $74,220. The 25th to 75th percentile range spans $59,180 to $70,900, showing steady earning progression with experience. Pay is influenced by several factors: union membership typically provides higher wages and better benefits, specialized skills like welding or rigging command premiums, and location within the state matters—Boise metro areas generally offer higher pay than rural regions. Experience level significantly impacts earnings, with journeymen ironworkers earning substantially more than apprentices. The type of projects also affects compensation—commercial high-rise construction, bridge work, and industrial facilities often pay more than residential or smaller commercial jobs. Idaho's construction market has remained relatively stable, with ongoing infrastructure projects and commercial development providing steady work opportunities. The state's lower cost of living (96.7% of national average) means the $62,190 median salary has greater purchasing power, effectively worth about $64,312 compared to national averages.

Idaho ironworkers typically enter the trade through union apprenticeships, primarily with the International Association of Bridge, Structural, Ornamental and Reinforcing Iron Workers. The most common path is through Local 732 (Boise) or Local 14 (Coeur d'Alene area). These 3-4 year apprenticeships combine 144 hours of classroom instruction annually with 2,000 hours of on-the-job training. Apprentices start earning about 40-50% of journeyman wages ($12-15/hour initially), with regular raises reaching 80-90% by the fourth year. Classroom training covers blueprint reading, welding, rigging, safety protocols, and structural engineering basics. Idaho doesn't require state licensing for ironworkers, but specific certifications enhance employment prospects—welding certifications (particularly structural welding), crane operation licenses, and OSHA safety certifications are valuable. Some employers prefer candidates with construction-related education from Idaho's community colleges like College of Western Idaho or North Idaho College, though it's not required. Pre-apprenticeship programs through Idaho Department of Labor can help candidates prepare. Military veterans with construction experience often receive credit toward apprenticeship requirements. The state's apprenticeship completion rate is strong, and union training facilities in Boise provide hands-on training with actual steel structures. Non-union paths exist but are less common and typically offer lower wages and fewer benefits.

The $24,000 gap between the 10th percentile ($50,220) and 90th percentile ($74,220) reflects several key differentiators in Idaho's ironworker market. Experience is the primary factor—entry-level workers and those with 1-2 years earn at the lower end, while journeymen with 10+ years command top wages. Union membership significantly impacts earnings, with union ironworkers typically earning $8-12 more per hour than non-union counterparts, explaining much of the upper percentile earnings. Specialized skills create pay premiums: certified welders, especially those qualified for structural and high-strength steel welding, earn toward the 75th-90th percentiles. Location within Idaho matters considerably—Boise metro area projects pay 15-20% more than rural or smaller city work. The middle 50% earning $59,180-$70,900 represents experienced non-union workers and newer union members. Top earners ($70,900+) typically combine union membership, specialized certifications, foreman responsibilities, and work on major commercial or infrastructure projects. Seasonal variation affects annual earnings, with consistent year-round workers reaching higher percentiles compared to those with weather-related layoffs.
