Choosing Your Post

Match the Post to the Panel

Post size is a structural decision, not a style one. Taller and wider panels carry more wind load, and gates carry more again — so both the section and the length change with the job. Here is how our post lengths line up with our standard panel heights.

1800mm and 2100mm lengths are also stocked for gate posts, sloping sites and custom panel heights.

• Setting into soil or new concrete? This post anchors below ground.
• Working to a slab, deck, path or existing footing? Our base plate posts run from 50mm through to 100mm.
• Finishing against a wall, pier or house? Our wall-mount post closes the run neatly.
• Not certain? Send us your run length, panel heights and site photos and our product specialists will spec it with you.

Installation

Get the Footing Right and the Rest Follows

Dig a minimum 600mm deep hole and concrete the post in, bringing it plumb with a level and bracing it until the concrete goes off. In reactive soils, go to a minimum 900mm for added stability. Once cured, snap the colour-matched cap into place.

That's it. And if anything about your site is unusual — a slope, a tight boundary, an awkward corner — call us before you start. We'd rather spend ten minutes on the phone than have you buy twice.
