Innovation at the Gate

Sigma holds a special place in our range — not just because it was the first rear access parcel box of its kind in the UK, but because it represents everything we value: good design, practical thinking, and uncompromising build quality.
Manufactured exclusively for us by a third-generation family company in Eastern Europe, Sigma is shaped by a tradition of craftsmanship that began at a blacksmith’s forge. Today, that legacy lives on in robust steel construction, precision finishes, and weather-tested reliability that’s built to withstand harsher winters than anything the UK can offer.
Whether you're fitting a new automated gate, upgrading fencing, or simply tired of missed deliveries, Sigma is a professional-grade solution trusted by UK gate installers and homeowners alike. Stylish, secure, and designed to last — it’s the parcel box that changed the standard.
