Service Line, Structural Steel

Structural Steel.
Erected, welded, accountable.

Erection of pipe racks, platforms, supports, and equipment foundations, AWS D1.1 structural welding integrated into the same crew that handles your piping and mechanical scope.

Nelvamar erects the structural steel that supports the piping and equipment we install. That single source coordination removes the typical structural vs piping schedule clash on Gulf Coast projects.

Scope

  • Multi level pipe rack erection
  • Equipment platforms, access ladders, stairways
  • Pipe supports, engineered and field routed
  • Equipment foundations and skid steel
  • Bolt up, plumb, and field welding to AWS D1.1

Welding & QA

Structural welding to AWS D1.1, performed by qualified welders to documented WPSs. Visual and NDE inspection per the project specification. Bolt torque logs and steel inspection records included in turnover.

Coordination

Because structural, mechanical, and piping share a crew at Nelvamar, schedule conflicts inside the rack get resolved at the foreman level, not in a multi contractor coordination meeting two weeks later.
