Stunning Gate at entrance way to Vineyards, in Central Otago. - 13th May 2019

Mondillo Gate Finished by Otago Engineering

This impressive Gate, manufactured by Otago Engineering, formerly A.J Grant, is positioned at the entranceway to 'Mondillo Vineyards' in Bendigo, Central Otago. This gate is produced in cor-ten steel, creating a stunning looking entranceway, fitting beautifully within its surroundings. Cor-ten steel also known as weathering steel is popularly used in gates and outdoor sculptures for its rustic antique appearance as if being exposed to the elements for several years.

The name of the Vineyard has been laser cut into the steel combined with 'positive cut' letters which have been incorporated into the gate. This gate is automated and slides open at the touch of a button, using top quality European Genius FAAC brand motors. The control systems for the motors are user-friendly and can be adapted to suit your security needs.

This beautifully designed, rustic steel gate, combined with the schist rock wall, is a pleasure to the eye, enhanced by the beautiful looking backdrop of Central Otago.

Our clients are thrilled with the gate and have had fabulous feedback!

Spiral Staircases, custom made to fit - 27th Jun 2018

Recently A.J Grant  was commissioned to build four Spiral Staircases to fit into apartments in Auckland where space was limited. The staircases were then manufactured and assembled in one piece in our workshop in Dunedin and then shipped to their destination in Auckland. On arrival they were transported to the site and craned into position with a minimum of fuss,   making this a cost efficient solution to use space saving stairs.


When we looked for manufacturers of good quality Spiral Staircases for our premium townhouse development in Auckland, we had a real struggle to find someone to manufacture these and even looked at manufacturers in Australia. In the end due to the obvious knowledge that can only come from years of experience and excellent service that Allan from Grant Engineering in Dunedin provided, we chose them to manufacture 4 of these complicated staircases. The end product was superb and their help in recommending appropriate coatings for coastal installation, as well as help in transporting these to Auckland was simply outstanding. To the entire team at Grant Engineering - thanks very much for your masterpieces—you rock!
