A Metalworking Legacy
Metal has shaped Spokane Valley's economy for generations. The Trentwood aluminum works, established during the World War II era, became one of the largest employers in the region and helped create a skilled workforce of machinists, welders, and engineers. Today, that heritage continues through a diverse network of fabrication shops, structural steel companies, foundries, and precision manufacturers.
These companies serve aerospace, construction, energy, agriculture, mining, and transportation customers. Their capabilities range from massive structural beams for commercial buildings to precision sheet metal parts for electronics enclosures.
Core Metalworking Capabilities
Local metalworks companies offer cutting, bending, welding, machining, casting, finishing, and assembly. Advanced equipment such as laser cutters, CNC press brakes, and robotic welders allows shops to produce precise parts efficiently, while skilled tradespeople handle complex custom work.

Metalworking Industry Trends
Automation is transforming metal fabrication, with fiber lasers, robotic welding cells, and automated material handling increasing speed and consistency. Aerospace demand continues to support aluminum production and precision machining. Infrastructure investment is boosting structural steel work. At the same time, the industry faces a shortage of skilled welders and machinists, prompting partnerships with Spokane Community College and apprenticeship programs to train the next generation.
How to Choose a Metalworks Partner
Identify the processes and materials your project requires, then confirm the shop has the right equipment and certifications, such as AWS welding certifications or AS9100 for aerospace work. Ask about capacity, lead times, and quality inspection procedures. Review examples of similar projects and request references. For structural work, ensure the company coordinates closely with engineers and general contractors.
Frequently Asked Questions
What is the difference between structural and precision fabrication?
Structural fabrication produces large components such as beams, columns, and trusses used in buildings and bridges, where strength and code compliance are key. Precision fabrication creates smaller parts with tight tolerances, such as enclosures, brackets, and machined components. Many Spokane Valley shops specialize in one area, while some offer both capabilities.
Can metal shops handle small custom projects?
Many fabricators welcome small jobs such as custom railings, trailer repairs, brackets, and agricultural equipment modifications. Smaller shops in particular often value one-off projects and local relationships.
Which metals are most commonly fabricated locally?
Carbon steel, stainless steel, and aluminum are the most common. Aluminum expertise is especially strong in the region because of its long history with aluminum production.
How do I get an accurate fabrication quote?
Provide drawings, material specifications, quantities, finish requirements, and deadlines. The more detail you share, the more accurate and competitive the quote will be.
What finishing options are available for fabricated metal?
Common finishes include powder coating, painting, galvanizing, anodizing for aluminum, and passivation for stainless steel. Each option offers different levels of corrosion resistance, appearance, and cost. In the Inland Northwest, where road salt, snow, and temperature swings are common, choosing the right protective finish can dramatically extend the life of outdoor components such as railings, trailer frames, and agricultural equipment. Many local fabricators coordinate finishing through trusted regional partners to simplify the process for customers.
Final Thoughts
Spokane Valley's metalworks companies carry forward a proud industrial tradition while embracing modern technology. From aluminum plate that flies in aircraft to steel frames that support new buildings, these companies deliver strength, precision, and craftsmanship that serve the Inland Northwest and beyond.
