B.T. STRUCTURAL STEEL MEMBERS

Composite Column

Columns in which a concrete core is reinforced with a steel or cast-iron core designed to support a part of load

Joist Girder

a light steel truss used to support open-web steel joists

Shear Plate

a plate fastened to the web of a plate girder to increase its resistance to shearing stresses

I-beam

a rolled or extruded metal beam having a cross section resembling an I.

Web Plate

a steel plate forming the web of a plate girder

Open-web Steel Joist

A K-series joist has a web consisting of a single bent bar, running in a zigzag pattern between the upper and lower chords.

Steel Beam

A beam consisting of a single or built-up structural steel section

Composite Beam

A beam structurally connected to a concrete slab so that the beam and slab respond to loads as a unit.

Flange or Stem

A broad ridge or pair of ridges projecting at a right angle from the edge of a structural shape in order to strengthen it.

Box Column

A built-up steel column consisting of a single or multiple shafts rigidly connected by lacing or cover plates.

Open-web Steel Joist

A lightweight, fabricated steel joist having an open web.

Cover Plate

A plate fastened to the flanges of a plate girder to increase its section modulus in area subject to high-bending stresses.

Pipe Column

A section of structural steel pipe used as a vertical support

Box Girder

A steel beam built up from shapes and having a hollow, rectangular cross section

Castellated Beam

A steel beam fabricated by dividing the web of a wide-flange section with a lengthwise zigzag cut, then welding both halves together at the peaks, thus increasing its depth without increasing its weight.

Built-up Column

A steel column fabricated from a number of structural steel shapes, such as W shapes, channels, angles and plates.

Plate Girder

A steel girder built up from plates or shapes that are welded or riveted together

Web

An integral part of a beam that forms a flat, rigid, connection between two broader, parallel parts, as the flanges of a structural shape.

Flange Angle

One of the angles forming the top or bottom flange of a plate girder

Lally Column

Steel support columns filled with concrete.
