Structural Steel Welding That Supports Your Project From the Ground Up
Structural steel plays an essential role in buildings, commercial facilities, industrial structures, and many types of construction projects. However, even high-quality steel components depend on properly executed connections and welding procedures to perform as intended.
At Lukens Certified Welding, we understand that structural welding involves more than joining two pieces of metal. Every connection needs to account for the project’s design, material requirements, and applicable structural specifications.
Whether you’re working on new construction, remodeling an existing building, or reinforcing a structure, our team can review your welding requirements and discuss the appropriate approach. We work closely with general contractors throughout Southern California, providing structural steel welding and fabrication experience for projects of varying complexity. For components that go beyond welding alone, our custom metal fabrication capabilities can help.
