Architectural Fencing Gemini Convex | Decorative Ornate Fencing | Zaun

08. Gemini Concave

Gemini Concave architectural fencing from Zaun features a curve effect at the top of the twin wire mesh system. This curve goes below the height of the post, creating an attactive concave shape. One of four options available in the Gemini range (wave, convex, concave and surf), each of these architectural fencing styles share the curvaceous styling associated with the Gemini range. Each style however is different enough to allow radically different styles to be selected depending upon the setting. Gemini Convex works perfectly along side Gemini Concave to create a stylish convex, convave wave.

Our architectural fences have the ability to break up rigid fence lines and are perfect for areas that are aesthetically sensitive or which are on show to the public or customers. The Gemini architectural fences are based on the twin wire fencing systems Duo6 & Duo8, that use twin horizontal wires to sandwich the single vertical wires.

Each architectural fencing panel is supplied with anti-tamper security fixings and fixed to the posts using full length clamp bars. The full length clamp bar makes levering the panels away from the post very difficult and ensures that there are no exposed panel edges on which people may snag themselves on.

Due to its strength and great looks, Gemini fencing is ideal for housing projects, schools and prestige projects where the fence needs to be a feature as well as a boundary.

Gemini is measured at post height, so the panels may exceed that height at the centre of the panel, depending on the style that has been chosen.


All Zaun posts/panels/gates and painted auxiliary components (for example, clamp-bars, slide bolts etc.) benefit from a protective zinc layer and electrostatically applied polyester powder coating to BS1722 p16. Care is taken with pre-treatment to ensure sound adhesion between the zinc and paint layers. In a UK C1 environment, as defined in ISO 12944 p2, this should ensure a useful life expectancy of the fence of at least 15-20 years. Life expectancy in all environments can be extended by maintaining the fencing with regular washing. Useful life will be reduced if the fencing is damaged. Any coating damage should be repaired to reduce the effect on useful life.

Enhanced painting systems such as marine coatings are also available for improved life expectancy in C2-C5M environments.
