BAC (Boeing Extrusions)

Extrusions & Rolled Sections

We stock an extensive range of BAC (Boeing) extrusions and rolled sections.

Boeing is one of the largest and most recognised companies in the aerospace industry, and the requirement for extruded shapes for the MRO market is critical.

Boeing extrusion shapes are referred to with a Boeing BAC part number. Boeing extrusions can be angles, channels, T sections, seat tracks, H beams, Z sections and many other shapes. Boeing extrusions and Boeing roll form shapes are part of our core stock range at Smiths MRO, and we offer a broad stock inventory of products to support the aerospace MRO market sector.


The first part of the Boeing BAC part number identifies the shape, and the second part identifies the specific sizes and dimensions of the part.
