100mm (W) Fencing Supplies & Metalwork

100mm (W) fencing supplies are precision-engineered to fit standard 4-inch timber posts perfectly, keeping your boundary straight and resistant to heavy movement. This exact width ensures your galvanised mild steel or powder-coated steel supports seat correctly against the post, giving you the necessary leverage to keep fence panels upright and aligned. They are essential for  a professional build, preventing wobble and protecting the timber base from direct contact with ground moisture.

Designed with performance in mind, our range of 100mm fencing supplies includes drive-in spikes and bolt-down post shoes from trusted brands like Powapost. You will also find post extenders and other essential metalwork to help you achieve a secure boundary in any soil or surface condition, ensuring a rigid, reliable setup that lasts.
