New! Vertical balustrade cables

This is a sneak peek of our new range of Stainless-Steel fittings for Vertical cables in balustrades that terminate in the metal post and specifically do not go through the posts.

Vertical Stainless-Steel cable balustrades have become very popular in Europe and are starting to form part of building regulations in those countries. Tensile Cables always endeavor to remain at the forefront of new and cutting-edge product development. Tensile Cables has specifically designed smaller and more economical fittings in order to make this range available in the South African market.

Australian Building regulations specify if your balustrade is higher than 4 meters up you are required to install vertical cables.  Vertical cables are almost impossible to climb. Vertical cables are ideal around swimming pools with the added safety measure of preventing children from climbing over the balustrade. All materials are grade 316 Stainless Steel.

Garapa deck & Stainless Steel cables in Tamboerskloof

Today we showcase a Beautiful Garapa wood balustrade with a deck using Stainless Steel cables overlooking the leafy green Cape Town suburb of Tamboerskloof.

This home renovation involved building a balustrade consisting of Garapa handrail and  posts using Tensile Cables signature Stainless Steel cables. Garapa wood is a high density and very durable hardwood species that is ideal for exterior decking and balustrade. Our cables have the added benefit of being very inconspicuous once installed on the posts and really allow unobtrusive views through the posts. The steel wire rope is especially suited to elevated properties with balconies and decks where the client wants to retain the view.

Robert Mckendrick was contacted to assist with the design and installation of this Garapa deck and Balustrade with Stainless Steel wires.

Circular cities of the world: what can green infrastructure do?

Daniel Johnson, ESCP Europe

More than half of the world’s population currently lives in cities while projections show an increase to two thirds by 2050. Many people living in small areas means large amounts of waste, high resource consumption and loads of energy use. We can combat these issues with the ideas behind the circular economy.

If we were to envision our cities as circular cities, how would they look? Green. And why? Because achieving a circular economy means using nature as a template. With the help of green infrastructure, we can take nature as the example and transform our cities into circular cities.

Green infrastructure is a planned network of natural and semi-natural areas in urban areas strategically designed to solve problems with storm water management, heat stress, air quality and biodiversity, to name just a few examples. Urban trees, green roofs and facades and constructed wetlands are some common examples.

Greening roofs, mitigating waste

Achieving a circular city means ensuring the mitigation of waste. Green infrastructure reduces waste in the construction industry by increasing the longevity of exterior surfaces. With greening, roofs survive longer against harmful weathering and intense sunlight. The lifespan of conventional flat roofs can even be doubled with greening. As one city with a long tradition of greening roofs, Berlin even has green roofs reaching approximately 100 years in age.

Green facades also play a similar role by reducing the maintenance requirements of conventional facades due to the protective layer against sunlight and high temperatures. By using these nature-inspired measures in green infrastructure, cities reduce waste in the construction industry and become more circular. Making our buildings last longer means less waste and helps us approach the idea of circular cities.

Seeing storm water as a resource

One of the key roles that green infrastructure plays for cities is in the management of storm water. When it rains, storm water runs off sealed surfaces and is conveyed to wastewater treatment plants. During heavy rainfall events, the treatment plant’s capacity may be exceeded. This can cause combined sewer water and storm water to flow directly into rivers, severely degrading the quality of the water.

Although newer sewer systems allow for the separate conveyance of storm water directly into the rivers, the runoff from streets and sealed surfaces still washes pollutants down to the rivers as well. Green infrastructure reduces the amount of runoff to rivers by acting like a sponge. In Brooklyn, New York, a “sponge park” will help clean up the long-polluted Gowanus Canal. In China, the “sponge city initiative” focuses on helping cities to absorb more rainwater to mitigate flooding, increase the water supply and reduce pressures on the municipal treatment systems. Reducing and reusing runoff not only mimics nature’s own circular way of dealing with rainwater, but also reduces energy consumption at the wastewater treatment plants.

Many cities have already taken great strides in addressing storm water in a circular fashion. In Berlin, for example, one section of Potsdamer Platz with 30,000 square meters features an entire system of connected green roofs, urban spaces, and a constructed treatment pond for handling storm water. By naturally treating water in the pond, very little energy is needed to clean the water, which is then reused for irrigation and flushing toilets. Toronto has even made green roofs obligatory since 2009 in order to manage storm water, and Malmö’s Bo01 Development even incorporates 100% renewable energy while also handling and treating all the storm water sustainably.

Energy consumption

Reducing energy consumption at treatment plants is just one way in which green infrastructure can aid in mitigating greenhouse gas emissions. Green roofs and facades act as an extra source of insulation and protection against temperature extremes: reducing indoor temperatures in the summer and increasing temperatures in the winter. As 40% of the total energy consumption in the EU can be attributed to the building sector and over a third of greenhouse gas emissions originate from buildings, reducing the heating and air conditioning could play a large role in cities’ efforts to mitigate climate change.

Besides reducing energy consumption and subsequent greenhouse gases, green roofs and facades also sequester carbon dioxide and assist in the uptake of air pollutants such as nitrous oxide, sulphur oxide and particulate matter, the pollutants for which the guidelines from the World Health Organization are often not reached in cities.

Even more benefits?

To top it all off, greened surfaces are appealing. People enjoy seeing more green in their direct environment, which is crucial for those primarily residing and working in built-up urban environments. Studies have shown that looking out over greened surfaces reduces recovery time of patients in hospitals and reduces psychological stress and depression of workers in urban environments.

Furthermore, increasing the green in cities combats the urban heat island effect and protects human health. For example, at Potsdamer Platz, the summer temperatures are kept 2°C cooler than other surrounding areas.

Considering the numerous benefits, it is clear that cities investing in green infrastructure become more circular and tackle several issues at once. Studies have already shown how economically the benefits do outweigh the costs of such systems, and it is obvious that there is much to gain in mimicking nature and transitioning to circular cities of the world.

Spier Arts Academy vertical cables

Robert McKendrick of Scotchworx Carpentry was tasked to design and install vertical cables for a balustrade at the Spier Arts Academy at Union House in Commercial street, near the Parliament of Cape Town.

Stainless Steel 4mm thick cables were connected to manufactured steel channels rather than the historical existing Oregon timber handrail in order to preserve it in its original condition. Steel channels were secured onto wooden ceiling beams and near the wood floor for the vertical cables to fasten onto using Tensile Cables versatile swaged stud system. The high ceiling is complimented by the Vertical cable design in the room and the rich yellow color of the old Oregon timber blends very well with our Stainless Steel cables.

 

Riposatevi Installation by architect Lúcio Costain in Brazil

All images and Text description provided by the architects. RIPOSATEVI (Meaning: take a rest) is an installation designed by the architect Lúcio Costa for Milan’s Triennial of Architecture, held in the fateful year of 1964. In 2018, the work is presented for the first time in Rio de Janeiro and inside a museum of visual arts – the MAC of Niterói, designed by Oscar Niemeyer.

After an invitation of the curatorship of the MAC, gru.a’s team worked on the adaptation of the system created by Lucio Costa to the singular geometry of the hall designed by Niemeyer, with the challenge of mediating a posthumous meeting between two of the greatest characters of Brazilian architecture.

The installation occupies the 400m2 of the main hall of the museum. A horizontal wire rope formed by equilateral triangles was fixed 2.5 m from the floor. From it 13 vertical risers are fixed to the bases of the beams of the building, connecting the system of cables of steel to the structure in reinforced concrete of the MAC. For each cabled point hooks were installed where the 30 networks that occupy the space are hung.

Johannesburg-based architectural firm Nicholas Plewman Architects designed this lodge in Ruaha National Park, Tanzania. Jabali Ridge is a beautiful, sophisticated building set amid huge granite boulders with mesmerising views across the vast wilderness of the National Park.   It overlooks a landscape dotted with spiky palms and bulbous baobabs and blends seamlessly into the natural surroundings with an elegant, contemporary style.   It’s truly a special place to stay.

The building has a low-profile balustrade which offers undisturbed views of the National Park. Emerging from the raw landscape, the lodge is made of a permeable timber structure to provide unrestricted vantage points to immerse the visitor in the wilderness. Tensile Cables wanted to showcase this magnificent lodge to illustrate the importance of the unobtrusive balustrade.

If you love to sleep among natural raw materials, furniture and fixtures, this small vacation place can be a perfect choice. All rooms are completely open to nature, but guests are also able to close the structure with wooden shutters.

One of the primary design drivers was that the lodge shouldn’t be visible to the human eye from a distance,” said Nicholas Plewman Architects. The result is a building that blends seamlessly into the rocky outcrops of the region.”

Tensile Cables offers slim 3, 4 and 5mm Balustrade cables that deliver the simplicity of unobscured views and are a great addition to any balustrade. Our cables open your view of the wonderful African bush and are ideally suited to any balustrade or deck, be it for a lodge, or your town house in the city, or overlooking Table Mountain or the Atlantic Ocean.

Our Grade 316 Stainless Steel products are ideally suited for typical indoor or outdoor environments. The high quality and finish of our Stainless-Steel cables and fitting ranges is well known, making us the supplier of choice in Southern Africa.

Cummings: Suspended Staircase in Waterfall City

Tensile Cables was commissioned by A & D General Services to supply stainless steel cables to suspend a two flight staircase at the Cummins Southern Africa Regional Offices (CSARO) in Midrand. The Cummings Building forms part of the new Urban developments in the Waterfall Logistics Precinct in Waterfall City.

While other solutions were attempted to secure the staircase from a structural point of view, cables offered a more aesthetically pleasing solution to secure the staircase in the relatively small opening between floors. As you can see from the images the installed cables disappear and allow for a clean view through the open spaces whilst at the same time structurally still providing the required support.

Tensile Cables supplies Marine Grade 316 stainless steel cables and both 16mm and 6mm cables were requested to fulfil the brief.

Dr Pixley Memorial Hospital external sun louvers

Tensile Cables was tasked by Robertson Ventilation Systems with supplying Stainless Steel cable systems to structurally support external sun louvers for the Dr Pixley Ka Isaka Seme Memorial Hospital near Bridge City mall, north of Durban. External building facades have a direct impact and cost saving on the energy requirements of a building.

Tensile Cables manufactured 10mm Stainless Steel cables systems to length according to the specifications of the project. We supplied our specialist 10mm Swaged Toggle fork to Swaged Turnbuckle system and made all the cables up to length with our specialist in house swaging equipment.

The R2,5bn level 2 regional hospital, will serve as a referral center for all surrounding public health care facilities, and will alleviate pressure from the Mahatma Gandhi Memorial Hospital, which currently has a massive catchment area.

The brand new 500-bed Dr Pixley Ka Isaka Seme Memorial Hospital will open its doors, bringing quality healthcare service delivery to more than 1,5 million people of Inanda, Ntuzuma, KwaMashu (INK) and surrounding areas.

The new hospital will prove a full spectrum of up-to-date world-standard medical services consistent with the norms and standards adopted for all public health facilities in South Africa.

Among its many innovations is energy saving system with the building façade and a water harvesting feature through which rainwater will be harvested and then used for irrigation and ablution.

Colored Pavilion by Architect Martin Pelaez

Image from ArchDaily

All Text and description provided by the architects. Multicolored Pavilion, is a 50.0 m2 play pavilion designed for Fundaland, the inclusive and supportive park of Fundación A LA PAR. The Foundation works towards the rights and participation of people with intellectual disabilities in society. It has the archetypical shape of a house to show that it is an inclusive space, a home for all. It celebrates diversity through color, and the alliance between people by the intersections of the color lines.

The pavilion building process is divided in four principal milestones: platform, structure, graphics and envelope. First, a rectangular platform of reinforced concrete of 13 meters long and 7 meters wide, was built in an outdoor enclosure of the park. In second place, the structure, a 5-meter-high metal gabled skeleton was installed on site anchored to the concrete platform.

The structure designed in parts to be easily assembled in place, shortening execution times. The 3 main gabled frames were joined by 12 beams and 12 cables, that brace the main structure in all directions. It was completely assembled in 6 hours. As a supportive feature to the structure work, two large steel doors of 2.5-meter-long by 4.5-meter height were installed on the front elevations.

These big doors have three purposes: ensure the natural ventilation of the space, frame the views of the greenery of the surroundings from the inside, and keep the activity of the space visually open to everyone, in matter of fun, communication and control.

The custom-made colors chosen for the project, conceptually respond to a blend of the primary colors and the corporate colors of Fundaland.
