When standard 50mm or 65mm square posts are not sufficient for the application, the 75×75mm square steel post provides the extra strength needed for taller fences, exposed locations and medium-duty applications.

FPM Building Supplies stocks square steel posts in 75×75mm and a full range of sizes for fencing projects across Victoria.

What Is a 75×75mm Square Steel Post?

A 75×75mm square steel post is a hollow square section (SHS) steel post with a 75mm × 75mm cross-section. It is galvanised for outdoor and in-ground use and provides significantly greater strength than smaller square post sections.

When to Use a 75×75mm Post

75×75mm posts are suited to:

• Taller Colorbond fences (2.1m or above)
• Fences in exposed or windy locations
• Gate posts for standard residential gates
• Corner and end posts where extra strength is required
• Applications where engineering or council requirements specify a larger post section

75×75mm vs 100×100mm

75×75mm — suitable for most medium-duty applications including taller residential fences and standard gate posts.

100×100mm — for heavy-duty applications, large gates, commercial fencing and applications where engineering specifies the larger section.

Available Colours

Square steel posts are available in Colorbond colours including Monument, Woodland Grey, Night Sky and Basalt.
