Structural Steel Detailing

Structural Steel Detailing is the production of detailed drawings for steel fabricators and steel erectors to use in the construction of buildings, bridges, and other structures.


Steel detailers prepare detailed plans, drawings and other documents for the manufacture and erection of steel columns, beams, braces, trusses, girders and miscellaneous steel like stairs and handrails. Steel detailing is a critical communication connection that unites key experts such as engineers, architects, contractors, fabricators, and others who are involved in the project at any level.


Structural steel detailing is an important, mandatory process in all types of manufacturing and construction activities, such as erection of residential and commercial buildings, factories, and institutes, as well as shipbuilding. This is a critical process of structural engineering and demands near-99% accuracy. Even a tiny error can lead to a loss of valuable time and money.

Structural steel detailing necessitates the development of comprehensive drawings for fabricators and contractors, as well as plans, estimates, and other necessary reports and activities. There are two sorts of drawings used in this process: shop drawings and erection drawings.

 Shop drawings: Each steel element, such as joists, beams, columns, and braces, are meticulously detailed in the shop drawings. This describes how steel fabricators should make each component. Component dimensions and sizes, bolting, welding, material specifications, and other details required for each component’s fabrication are all  included in the shop drawings.

Erection drawings: The erection drawings specify the geographic placement of each steel component within the structure and detail the dimensioned plans. These drawings detail the position of each component, the installation requirements, and any other field work involved with the project, such as the installation of welding spots, wedge anchors, and bolts.

Steel detailing services also include other important stages such as reinforcing steel detailing, anchor setting plans, steel design, connectivity diagrams, shop bolt summary and BoM (Bill of Materials).

Steel detailing standards

The detailer is required to comply with the steel detailing standards of different countries, such as those specified by the:

  • American Institute of Steel Construction (AISC)
  • American Welding Society (AWS)
  • National Institute of Steel Detailing (NISD)
  • Canadian Institute of Steel Construction
  • Australian Institute of Steel Construction
  • Euro Codes and British Standard Codes

The design, strength and integrity of steel structures are the responsibility of the structural engineer, while complying with the major dimensions and building codes are the responsibility of the architect. The detailer is responsible for getting the steel detailing drawings approved by the structural engineer and the architect prior to release for fabrication.

This specific steel structures are widely used in USA for building construction, stadium, warehouse etc. But, apart from USA, including India, it is not so popular choice of engineers while they do design buildings or other structures. Here, we will discuss few benefits and features of Open Web Steel Joist.

R. Donald Murphy (Managing Director of Steel Joist Institute) wrote an article, where he described the benefits and features of using open web steel Joist.

  • Strength-to-Weight and Multi-Directional Strength
    More and more engineers are weighing the benefits of steel and steel joist construction. One reason is the amazing strength-to-weight ratio of steel joists which typically runs 25 to 1. And, steel can perform in both tension and compression,unlike concrete which must be steel reinforced to resist tensile forces.With their high strength-to-weight ratio, steel joists can support greater loads. Steel itself is a wonderfully ductile material. This ductility means that steel can be more forgiving than concrete in situations such as the recent earthquakes in California. Steel can take uplift and gravity loading because steel has inherent strength in each direction.
  • Economy
    A high strength-to-weight ratio coupled with low price per pound of steel joists contributes significantly to lower building costs. An additional economy stemming from joists’ light weight is that structural supports such as beams, columns and foundations can be lighter in many cases. This further reduces material cost.
  • Cost-Saving Ease of Erection
    Steel erection is faster than concrete. You don’t have the expensive labor costs for setting custom-fitting forms and installing reinforcing rods at the job site. You can work with steel in almost any weather, whereas concrete pouring is limited below 40° F. and, in some cases, is not recommended when
    the temperature exceeds 90° F. And, you don’t have to wait for curing and stripping forms because, once
    the steel joists are properly erected and the deck installed, you’ve immediately created a permanent
    working platform to begin construction of the next level.
  • Durability
    Naturally, steel joists are subject to corrosion if left unprotected and exposed to hostile environments.
    Concrete can be affected in a similar way. It can crack and crumble when subjected to moisture and temperature extremes. However, steel joists have proven to be extremely durable in enclosed construction. Many years ago a bank building in New York City was tom down. The steel joists used in the construction had not suffered any deterioration despite being over 80 years old. And, the shop marks were still visible on the joists.
  • Infinite Flexibility
    There is infinite flexibility in the design of a steel joist building because each joist is custom fabricated
    to the designer’s specifications. A variable number of depths, spans and load-carrying capacities can be
    custom specified and produced at the factory avoiding expensive onsite labor. One example of the low cost and infinite flexibility of a steel joist is cantilevering. Cantilevering in concrete is an expensive, labor-intensive procedure. This involves considerable form set-up and carpentry to build the supporting structure to hold the concrete until it cures. With steel joists, cantilevering can be done by specifying an
    extended end or a full-depth cantilever. All of this work is done at the factory. The design flexibility of long spans can also be achieved by using steel joists. Spans of over 100 feet are not uncommon. This is not only a factor in new construction, but the greater number of support-columns needed in concrete construction often limits the designer’s ability to move walls and partitions when buildings are remodeled.
  • What You See Is What You Get
    In an age of increasing liability and fault-finding, steel joist construction is much easier to inspect because it’s exposed. The specifier can see what’s been used and what’s been done for himself. He can check the design, measure every member of the joist and review connections and fastening methods. Once concrete is poured the reinforcing bars are hidden from view. The specifier must then rely solely on the integrity of his contractor and the construction crew to assure that the job has been done properly.
