Structural & Miscellaneous Steel Features


Structural steel is a highly durable and corrosion resistant metal. It is an excellent choice for construction as a lightweight building material. Buildings constructed with structural steel have a minimum life span of about 20-30 years if well maintained.


Structural steel is cost effective and easy to install after fabrication. With increased efficiency in the installation process, a considerable amount of money and time is saved.

Environmentally Friendly

Steel is the most recycled material in the world, with domestic mills recycling more than 70 million tons of scrap each year. Currently, structural steel includes 93% recycled content. Choosing steel as a construction material is an excellent environmental choice.

We utilize a variety of structural steel shapes specified by our customers.

We have a variety of structural steel designs that we provide for our clients. If one of the designs does not fit with your project, we will happily accept any custom structural steel designs to fit your specific needs.

Steel W-Beam

A W-beam or a wide flange beam, comes in a wide variety of sizes from 4″ tall to 44″ tall. This steel beam type has a beam wedge and beam flanges. The flanges are the top and bottom members of the structure, while the web is the vertical member that holds the two flanges together. Each of the three members that create the beam are flat and straight. These beams are commonly used in commercial construction to span between columns and help support the load of the building.

Steel American Standard Beam


The American standard beam has a rolled section with two parallel flanges, all connected by a web. The designation of the S-shaped beam gives the builder information about each unit’s width and weight.

Steel I-Beam

An I-beam, also known as an H-beam or a universal beam, has two horizontal elements. The web is capable of resisting shear forces, while the horizontal flanges resist most of the beam’s bending movement. We endorse this beam frequently to our customers because of its variety of sizes it offers for the construction industry.

Steel Channel (C-Shaped)

Structural C-channels, or C-beams, have a C-shaped cross section. We utilize C-shaped beams because they are cost effective solutions and were originally designed for bridges. These are most popular for use in marine piers and other building applications.

Steel Angle (L-Shaped)

Angle beams take an L-shape, with two legs that come together at a 90 degree angle. They come in equal or unequal leg sizes. The L-beams are best used in floor systems because of the reduced structural depth.

Steel Tee Beam

A tee beam, or T-beam, is a load bearing beam with a T-shaped cross section. It does, however, pose some disadvantages, but there are ways to make it more structurally efficient. Fabricated tee beams can withstand large loads when making the T-beam inverted and pairing it with a floor slab or bridge deck that joins the two together.

Steel Hollow Steel Section (HSS)

HSS is a metal profile that has a hollow, tubular cross section. It can be square, rectangular, circular, or elliptical.

Steel Pipe

Structural steel pipes are important for a variety of construction applications, lending strength, and stability. The pipes are hollow, cylindrical tubes that come in a variety of sizes and are often used to meet the needs of water, oil, and gas industry projects.
