05 21 00 Steel Joist Framing
Use this CSI 3 part SimpleSpecs™ master specification to steel joist framing.
The section includes open-web steel joists and joist girders typically fabricated from steel angle upper and lower flanges with steel bar or angle diagonal webbing.
This section should be edited by or under the supervision of the project’s structural consultant.
Steel joist framing sometimes referred to as open web joist framing, consists of upper and lower chord members that are typically back-to-back angles with a steel bar or angle web members. Steel joist girders are available for longer spans. The open configuration allows for the placement of piping, ducts, conduit, and wiring without cutting. Large ducts may require special factory-framed openings.
Steel joist framing that is exposed to weather should be galvanized or protected by a high-performance coating system to minimize rusting.

The SimpleSpecs™ master specs concept
Design professionals are accustomed to seeing lengthy project specifications, so why is SimpleSpecs™ so short?
Specifications have grown evermore wordy over the years for several reasons:
The mistaken belief that specifications must be lengthy and legal-sounding to be enforceable. In fact, quite the opposite is true. Having shorter, easily understood specifications makes us less likely to have problems in the field.
A belief that having lots of words protects us from a Contactor making mistakes. There is no way to include enough statements to protect yourself from a bad contractor, regardless of the length of your specification.
Our desire to be in control of the project by specifying means and methods instead of including simple, enforceable statements.
Easier to Edit
SimpleSpecs™ is written as a series of Microsoft word files that include statements that affect construction costs or overall quality and are far simpler to edit than other master specification systems.
Each SimpleSpecs™ specification section is non-proprietary and includes three manufacturers that meet the specified reference standards, descriptive, or performance-based requirements. They are written to allow any listed manufacturers to provide the specified products.
Hidden Guide Text
Each SimpleSpecs™ specification section includes hidden text to inform and guide users in editing the specifications to suit project conditions.
SimpleSpecs™ sections are edited using pre-defined options that are contained in [brackets] or by selecting optional text separated by "OR" statements. Paragraph and page numbering are included as automatic codes, eliminating the need to renumber when revisions are made manually. Global changes to headers, footer, terms, font colors and phrases are easily updated using a third-party search and replace software, available through ZeroDocs.com.
