Saudi Building Code SBC 306 for Steel Structures: An Overview

An overview of the Saudi Building Code for steel structures (SBC 306), how it relates to SBC 301 loads and AISC-based design, and what it means for owners, contractors and fabricators.

Saudi Steel Work Editorial Team · · 3 min read

Short answer: SBC 306 is the part of the Saudi Building Code that governs the design and construction of steel structures. It works with SBC 301 (loads and forces) and other SBC parts, and is closely based on American AISC practice. Engineers use it for member and connection design; fabricators and erectors follow its quality and construction requirements as specified.

The Saudi Building Code (SBC) is the Kingdom's national building code, with parts covering loads, structures, fire, energy, plumbing and more. SBC 306 covers steel structures.

Basis of SBC 306

SBC 306 is closely aligned with AISC 360 (the American specification for structural steel buildings), with Saudi adaptations. Engineers familiar with AISC methods (LRFD and ASD) will recognise its approach.

What it covers (in general terms)

  • Materials and their specified properties
  • Design of members: tension, compression, flexure, shear, combined forces
  • Stability and second-order effects
  • Connections: bolts, welds, connecting elements
  • Serviceability
  • Fabrication, erection and quality requirements

What it means for project teams

Owners: require designs and shop drawings that comply; consultants verify.

Contractors and fabricators: follow material, fabrication, welding and erection requirements and the project's quality plan.

Buyers: supply materials meeting specified standards with certificates (mill test certificates).

Frequently asked questions

Is SBC mandatory?
The Saudi Building Code is mandatory for building projects within its scope, and compliance is part of permitting and inspection processes.
Does SBC 306 allow European steel grades?
Materials must meet the code's material requirements; use of other standards' grades should be justified and approved by the responsible engineer.
