News: Macalloy reach amazing new heights


High strength steel bars manufactured by Macalloy in Rotherham have been used in an architectural wonder that offers visitors an intense sensation of walking in the clouds.

Dinnington-based Macalloy are world leaders in design, manufacture and supply of threaded bar and cable systems to engineering and construction projects across the globe. Approximately 80% of the company's turnover is from export.

The Sky Walk near Dolni Movara, a ski and activity resort in the Czech Republic, is a 55 metre tall observation tower, built mostly by hand on the top of a mountain.

Designed by local studio franek architects, there are various attractions including a 101 metre long slide, nets and nests in the building for those who seek adventure or entertainment. The entrance building is of a slightly oval shape much like a rowboat.

Its construction is made of glued wooden beams set into a wooden grid supported by columns. The architectural approach was for the building to blend with it's unique surrounding rather then to disturb it. This was the reason for using wood for the major part of the construction, and making the rails and mounts as subtle as possible.


To make the architect's vision a reality, construction firm, Taros Nova, selected Maccalloy products. Macalloy has supplied 460 grade galvanised tension rods in M30, M36 and M42 with turnbuckles. Overall, the unique structure includes 550 cubic metres of timber, nearly 400 tonnes of steel and over 40,000 pins, clamps and bolts. Construction completed at the end of 2015.

Zdenik Fránek, lead architect on the project, said: "It is rare to use timber on a construction of this magnitude. It also creates a new kind of experience where people realise how small they are in the bosom of nature. I don't know of any other timber construction with steel elements of a similar size and purpose. There are constructions of a similar size but ours takes on an abstract form that suggests the flight of a nocturnal butterfly whose path is seemingly chaotic."

Radek Ondruch, executive director Taros Nova, added: "The construction was a unique experience that required us to follow a path of courage and self-knowledge. We found ourselves in a completely different situation from what we're used to – having to build so high above sea level in difficult terrain with changeable weather, where all of the materials and equipment had to be transported. It was astonishing and chilling at the same time.

"It was like when the first New York skyscrapers were built. Images of the Empire State Building being built came to mind."
