Galvanised SHS (Square Hollow Section) posts offer a clean, modern profile that suits contemporary fencing and retaining wall designs. Unlike the flanged profile of UC or UB sections, SHS posts have a square cross-section that creates a neat, uniform appearance — making them a popular choice for visible applications where aesthetics matter.

FPM Building Supplies stocks galvanised SHS posts for fencing and retaining projects across Victoria.

What Is an SHS Post?

SHS stands for Square Hollow Section — a structural steel tube with a square cross-section. Unlike UC (Universal Column) or UB (Universal Beam) sections, which have an I-shaped or H-shaped profile, SHS posts are hollow and square, giving them a clean, contemporary look.

Our SHS posts are hot-dip galvanised for corrosion resistance in outdoor and in-ground applications.

SHS Posts vs UC/UB Posts

The choice between SHS and UC/UB posts depends on the application:

SHS posts are suited to:

• Applications where a clean, square post profile is preferred aesthetically
• Lighter-duty fencing and retaining applications
• Decorative or feature fencing where the post is visible
• Colorbond and timber fencing systems

UC/UB posts are suited to:

• Structural retaining wall applications where engineering specifies a UC or UB section
• Heavier-duty retaining walls with significant lateral loads
• Applications where the post is largely hidden within the wall system

For structural retaining wall applications, always confirm the required post section with your structural engineer.

Available Sizes

FPM Building Supplies stocks SHS posts in a range of sizes to suit different applications. Common sizes include 75×75mm and 100×100mm sections, as well as smaller sections for lighter-duty use.

Galvanising for Long-Term Performance

All our SHS posts are hot-dip galvanised, providing a thick zinc coating that protects against corrosion in outdoor and in-ground conditions. This is particularly important for posts embedded in the ground, where unprotected steel would corrode relatively quickly.

Applications

Galvanised SHS posts are commonly used for:

• Colorbond and steel panel fencing
• Timber paling fence systems
• Feature fencing and gate posts
• Lightweight retaining applications
• Commercial and industrial fencing
