Challenge

IOTA was commissioned to design and manufacture bespoke planters with integrated seating for the roof terrace of a new corporate HQ in Aberdeen.

Project detail

Given the exposed location and harsh environment, and therefore risk of corrosion, 3mm-thick aluminium was specified, powder-coated to RAL 7016 [Anthracite grey] in a robust, hard-wearing paint formulation. The formed arm rests were manufactured from 8mm-thick 1.4003 powder-coated stainless steel – a material with unique advantages, as discussed here. The timber used was European Oak.

The essential design concepts appear deceptively simple but this was in fact a challenging brief. Specifically, designs based on non-constant radiuses are always a challenge in sheet metal and, on this project, the complexity of the radiuses was extreme (for example, the shape of the linear bench, end-to-end, evolves through no less than 12 different radiuses).  

Such shapes generate significant manufacturing challenges in sheet metal – specifically:

  • With designs based on non-constant radiuses, the forming is much more complex than simply rolling a sheet of metal into a constant radius.

  • Such shapes are also harder to weld – particularly in aluminium, which is inherently a more challenging material than steel in which to manufacture.

  • With timber benching, non-constant radiuses also mean that no single machined profile will be able to create the overall form and arrangement, therefore multiple CAD models and multiple machining batches are required, significantly adding to complexity. For the benching on this project, over 200 individual timber profiles had to be machined in 11 different profiles, each with its own CAD model.
