Whether it is a Wide Flange beam or a Standard I-Beam, Saginaw stocks all the common sizes of structural steel beams, along with the hard-to-get items. Our Wide Flange beam inventory includes sizes from 4” up to 44” wide beams. We stock most all of them in five-foot increments, starting at 35’ and going up to 60’ in all sizes, and up to 70’ in a select few sizes. We stock our Standard I-Beams in sizes from 3” up to 24” and keep them in a wide selection of sizes and lengths as well. We have the capability of saw cutting up to 27” beams and torch cutting the larger beams. If your material requires blasting, we can provide that service as well.

Wide Flange Beams (W-Beams)

Wide flange beams are ideal for load-bearing applications in commercial buildings, bridges, and infrastructure projects. These beams have broad flanges for superior strength and stability, making them a top choice when structural integrity is critical.

We stock wide flange beams in sizes ranging from W4" up to W44", with lengths typically available in 5-foot increments—starting at 20' and extending to 65'. Select sizes are even stocked up to 85'.

Standard I-Beams

Standard I-beams feature a narrower flange and are commonly used in light to moderate load applications such as residential construction, trailers, and support framing. We carry I-beams from 3" to 24" in a broad selection of lengths and weights to fit your project specifications.

Like our W-beams, standard I-beams can be cut to length and prepared to meet your jobsite requirements.
