We are American-made

Union ironworkers are specialists, providing contractors and owners the highest-quality craftwork on every project.

Some of the area’s most high-profile buildings, bridges, monuments, stadiums and sports arenas were built by members of the International Association of Structural, Ornamental and Reinforcing Ironworkers. Local 378 is a member of the international ironworkers association.

These are just a few of the areas we work in:
Structural Steel
Precast Concrete
Metal Buildings
Reinforcing Steel
Ornamental Iron
Fabrication
Curtain Wall
Welding and Rigging
Machinery Moving

Training

Local 378 ironworkers learn their craft in a federally-approved apprenticeship program. The joint apprenticeship training facility for Locals 377 and 378 is located at 3150 Bayshore Rd. in Benicia.

Union ironworkers don’t have a job; they have a career. That means Local 378 ironworkers are committed to delivering quality every day. The men and women of Local 378 take pride in being the best.

Learn more about job opportunities for skilled ironworkers here.

Safety

Union ironworkers learn OSHA safety regulations during a four-year apprenticeship program. On the job site, our men and women are committed to team work and each other’s safety, which reduces the number of accidents.

Building a skyscraper or building a career – union ironworkers take pride in their craft and in a job well done!

A New Way of Doing Business

Ironworker Management Progressive Action Cooperative Trust (IMPACT) is a broad coalition of ironworker union representatives and their signatory contractors.

The organization’s primary mission is to expand job opportunities and promote safety and training. It also allows ironworkers and contractors to discuss industry issues and mutual concerns.

To carry out its commitment to safety, IMPACT sponsors a drug testing program known as the National Substance Abuse Program. It runs a corresponding national database, allowing employers to know instantly that a drug-free work force is ready and available. All ironworkers, officers and staff are required to meet these drug and alcohol-free standards.

Contact us today to learn how our skilled, safe and drug-free workforce will help you meet your project goals.

    UPDATE on RSO-20 Hour course

    On October 7, 2017, the Governor of California signed into law AB55. In part, the law changes the implementation dates for the components of the 20-hour High Hazard Facility Training referenced in Health and Safety Code Section 25536.7, Sub Section (10) (C).

    Consistent with the new law, the following has been amended:
    • Effective dates for Part 1: 4-hours of Fundamentals of Refining and Part 3: 8-hours of Safety as it Pertains to Crafts have been extended to July 1st, 2018
    • Effective date of Part 2: 8-hours of Refinery Safety Overview, a carryover of the previous Refinery Safety Overview (RSO) training, will remain as originally announced: January 1, 2018

    Eligible members who contact our office will be required to schedule all three courses, totalling 20-hours of training. Local 378 will not schedule any portion of the training, individually.

    Please note: the High Hazard Facility Training is a 3-day training. Please keep this in mind when scheduling with Local 378 as the IMPACT attendance policy is still in effect.
