Triangle perforated metal is on point

Triangle perforated metal and prism shapes are the newest trend point in architecture, showcased in recent projects including in Tel Aviv and  Lahdelma & Mahlamäki’s ‘Trigoni’ cluster of high density smart towers in Helsinki.

At D3 House, the white aluminium triangular facade is perforated in key places, offering a tantalising glimpse of life inside whilst allowing light to shine out at night. Inside the property the triangle theme continues with perforated shapes in shelving systems and dividing walls for decorative light and shadow play.

Lahdelma & Mahlamäki’s winning plans for triangular towers in Helsinki allow the buildings to neatly slot together on the site, with the angle of each tower reducing overlooking but maximising light and views.

The triangle has returned to form as a top shape for perforated metal thanks to the sheer scope of patterns that can be achieved. When specified randomly, the effect is striking – take a look at the footbridge panels the Arrow Metal team created for Oatley Train Station’s redevelopment.

This incredibly complicated and intricate triangular pattern began with CAD drawing by our design team. Individual drawings were drafted for each footbridge panel, ensuring that each piece would not only perfectly fit, but achieved the architect’s design vision.

And although it might seem a random pattern, the placement of the triangles was actually very specific in arrangement. If you look closely you can see large, open perforations on the side for light filtration and views, and smaller-sized triangles on the roof for weather protection.

Triangle shapes on display

It’s not just in architecture that we’ve seen triangles emerge as an on-trend favourite. Cut-out triangles are delicately wearable for the custom display stands Arrow Metal made for Jay Productions & Events, for world-renowned jeweller Pandora.

Tiny triangles were used to create an intricate and uniquely feminine perforated lace pattern, the perfect platform to showcase the new DO range.
