AS/NZS 1163 SHS Dimensions for Cleat Connections: A Practical Guide for Structural Design
In Australian steel construction, accuracy and compliance are non-negotiable. When designing reliable steel connections, especially cleat connections, understanding AS/NZS 1163 SHS dimensions is critical. Square Hollow Sections (SHS) manufactured under AS/NZS 1163 form the backbone of many structural systems, and their dimensions directly influence the performance of cleat connections. This guide explains AS/NZS 1163 SHS dimensions for cleat connections , why they matter, and how engineers and builders can use them correctly for safe, compliant construction. What Is AS/NZS 1163? AS/NZS 1163 is the Australian and New Zealand Standard that specifies requirements for cold-formed structural steel hollow sections , including: Square Hollow Sections (SHS) Rectangular Hollow Sections (RHS) Circular Hollow Sections (CHS) The standard defines: External dimensions Wall thickness tolerances Corner radii Material grades (C250, C350, etc.) Mechanical properties For cleat connections, these ...
