Products that span your needs. Perfectly.
Our customers get superior steel from the ground up.
At Vulcraft, we built our reputation fabricating the best steel joists and decking. Our products are literally the backbones of buildings coast to coast and around the world. The following represents an overview of Vulcraft’s offerings.
Joists
Open web-steel joists are an engineered, truss-like construction component used to support loads over short and long spans alike. Typically used in non-residential construction, steel joists and joist girders provide an economical system for supporting floors and roofs. All Vulcraft joists and joist girders are designed and manufactured in accordance to the exacting specifications of the Steel Joist Institute.
Joists are separated by type and designated by letters: K, KCS, LH, DLH and SLH. The K and KCS joists are used for shorter span conditions where lighter loads are required. These joists are typically used in roof structures. KCS joists are a version of the K-series joists, but designed for a constant shear and moment, which allows for greater flexibility for locating extra loads such as those from rooftop units. LH- and DLH-series joists are for longer span conditions and are capable of supporting larger loads. These joists allow for special profiles to accommodate a variety of conditions. Some of the typical special profiles include gable joists and arched joists. SLH-series joists are used to support loads over very long spans, typically 120' and greater.
For more specific information regarding these joists, please consult the appropriate sections of Vulcraft’s Steel Joists & Joist Girder Catalog.
Composite Joists
Composite joists are designed to work in conjunction with the concrete in a flooring system. Shear studs are field attached to the joists prior to the pouring of the concrete for the floor. In many applications, joists used in this type of floor system are an economical way to construct a floor system.

Ecospan®
The Ecospan® Composite Floor System is an innovative, effective and economical method of providing all steel structural components for elevated floor construction. Plywood forms and shoring are not required, saving time and costly handling. Sub-trades can even begin work the day after concrete is poured. Joists are spaced at 4'-0" on center and the open web design allows easy access for HVAC and electrical trades.
The Ecospan® Composite Floor System is listed by Underwriters Laboratories Inc. with multiple fire ratings for acoustical and gypsum ceiling applications. Tested by a renowned acoustical laboratory, the system also received a Sound Transmission Classification (STC) of 57. Furthermore, additional tests performed with a variety of common flooring materials revealed an Impact Insulation Classification (IIC) of 50 (the IBC Code minimum) in all cases when typical sound attenuation materials were used.
Steel Decking
Steel decking is used in many applications, but is particularly well suited to roofing and flooring. Vulcraft manufactures many different types of deck, including roof deck, floor deck, composite floor deck and cellular deck. A full line of deck accessories, such as end closure and pour stop, is also available from Vulcraft.
