The Following Nine Projects Show How Architecture Has Made Stainless Steel One Of The Most Versatile Features For Construction.
Forget what you have heard about the price and the difficulty of handling the stainless steel. “The initial cost outstrips that of galvanized and carbon steels. But considering the high durability and low maintenance, the final cost will be lower, “says Arturo Chao Maceiras, executive director of the Nucleo Inox in São Paulo. Composed of iron, carbon and chromium alloy, the material has an invisible layer that protects against corrosion. Since he arrived in Brazil in the 1960s, advances have occurred both in the availability of colors and finishes (polished, brushed) and in the ways of working it. “A recent technology, the laser cutting, provides greater precision in the cuts and finishes of the plates,” exemplifies Claudio Magalhães, a researcher in the design area of the Pontifical Catholic University of Rio de Janeiro (PUC-RIO). The news instigates the architects – and although the annual consumption in the country is still low, it is estimated a growth of 12% a year. “The dissemination of the possibilities of stainless steel stimulates the increase in the supply of brands and trained labor,” says engineer Jorge Durão, of the São Paulo company Innova.
What Makes The Innova Company?
Jorge Durão Henriques , civil engineer at Innova Arquitetura Decoração e Construção, in São Paulo.
Our field of expertise is broad: we offer advice to architects and sometimes even to contractors. We commercialize the executive project for those who intend to work with stainless steel in the construction and even sell the material in the form of fabric, cladding, and skirting.
What are the myths about this type of steel?
We need to break the paradigm that it is a difficult material to work with and expensive.
It is important to remember that it may even cost more than carbon steel, but it does not rust, it does not need any painting. The architects have little information about stainless steel and end up not specifying in the works. If it were more used, we could double consumption in Brazil, which is so low. We are behind Chile, for example. It is also common for architects and laymen to associate this material with coolness. You need to look at it differently, since stainless steel can be mixed with bricks, ceramics and give a wonderful result. The contrast is nice.
Why Is Stainless Steel Rarely Used In Homes?
I believe the trend for 2011 is very good. We have to think that Brazil is growing and construction is on the rise. We just need to showcase the benefits of stainless steel, as well as better publicize it and offer information so that everyone knows their technical specifications. Today, it is widely used in countertops, wardrobes, handrails, but we can also use it in chandeliers, washers, baseboards, doors and door trims. We need to let creativity flow. All this will help expand the network that processes the products. There are few industries and much trouble finding the material. We also do not have much specialized labor. The same locksmith shop that works with aluminum and iron could work with stainless steel, however, they lack technical and trained workers.
Over Time, Stainless Steel Has Undergone Changes. What Were They?
Claudio Magalhães, industrial designer and professor of the Department of Arts and Design of the Pontifical Catholic University of Rio de Janeiro (PUC-Rio).
In recent years, the technology of laser cutting has emerged, which allows to make special pieces with exquisite finishes. Before, we had to saw the plates and we never got such good finishes. Colored surfaces have also begun to appear, enabling infinite applications.
When should I use stainless steel?
It has less environmental impact because it is easily recycled, and has high durability. You can find many colors and types of finishes. These advantages are excellent.
How to install stainless steel inserts?
Rogério Marques, director of the company Mozaik, from Belo Horizonte.
The boards are protected by a plastic and in our case, they have blue lines that indicate the direction of the brushed finish. Caution: Plastic must be removed only when grinding is finished, polishing it. First lay the coatings, apply the grout with EVA spatula (type of plastic that does not scratch the parts) and only then remove the plastic. Finally, the grout should be polished (remove excess grease) with a soft sponge.
What Types Of Grouts Are Indicated?
We have an acrylic product, developed by us, that does not contain sand (able to scratch the stainless steel). It is also possible to use epoxy grouts, manufactured by various companies. Never use products used to grout glass tablets, as they often damage stainless steel. In general, their mineral filler is sand.
Who Should I Hire For The Installation?
The same glass insert installer can work with the stainless steel coating. A professional usually settles from 10 to 14 m² per day, according to his ability.
The installation costs about R $ 45 m² (without the material), in Belo Horizonte. In São Paulo, this price should be doubled.
How To Do Maintenance?
When cleaning, avoid the use of steel sponges. Use only cloth, water and mild soap.
Why Use Stainless Steel?
Claudio Rampazzo, architect of São Paulo. I am passionate about this material, because it is hygienic, noble, non-staining and easy to work in all aspects – folds, cuts. I used it as a facade cladding in a factory in Guarulhos, in Greater São Paulo, and I loved it. It is a place subject to pollution, in bad weather, and stainless steel is unbeatable because it can handle all this perfectly. In Brazil, the great barrier is the cost, in fact, it is a mask. The square meter of products like marbles, synthetic stones and granite is higher than the cost of stainless steel, but no one does that. Another problem is the fact that everyone binds you to utilities such as cutlery and benches. Do not give the value due to stainless steel. Even I understand that today, in Brazil, there is great difficulty in finding this metal benefited. However, a good job of promoting stainless steel is being done.
Stainless Is Reputed To Be A Cold Material. How To Solve This?
It has to be used consistently. I will not adopt him in the middle of the room, for example. I can create something decorative, like the top of a coffee table. You can also mix it with other materials, rustic or not. I think we need to break this resistance. It can leave the spaces beautiful and has an immense range of colors and finishes.
As a work of art, the polished stainless steel staircase wrapped by thin steel ties was designed by Edo Rocha Corporate Spaces for a company from São Paulo.The cables, attached to the slab and the floor (Tetrabase’s execution) act as safety features. As for maintenance, use only stainless steel products and a soft cloth, since abrasive substances and sponges scratch the surface. Such care is indicated for all ideas shown in this report.
As the living room of this house from São Paulo opens onto the swimming pool, the architect Raul di Pace, from Di Pace and Di Pace, opted to close it with sliding glass doors. Thus, with the frames open, the living room becomes a balcony. In the meeting between the two spans of the frames, there is a 50 cm diameter concrete structural column. “To disguise it, I chose a mirror polished stainless steel coating,” he says. The sheet, 1.2 mm thick, curved by the calendering process, was transformed into a cylinder surrounding the abutment. The ends are joined in a profile of the same material, screwed into the concrete (execution of Brass Art).
During the installation, the panel on the glass panels of this house in Povoa de Varzim, Portugal, already attracted attention. “The neighborhood stopped to say that it recognized the acronyms, symbols of their families, laser-cut on steel plates,” recalls the Portuguese architect Jose Cadilhe, responsible for reform. I wanted to value the local traditions and at the same time bring an unusual solution, complete. The architect also chose stainless steel for its resistance to corrosion, since Povoa is a port city. In composition, the upper two rows open like shrimp-type windows. Below, part of the plates works as door.
In the shape of a rectangular column, the brushed steel hood from this Delta kitchen in Sao Paulo inspired the choice of wallcovering just behind. I opted for the same material, but in a different configuration. So, instead of plates, I chose stainless steel inserts ??, says Sidnei del Vai, a partner-owner of the company. He commissioned pieces in the polished and brushed versions (2.5 x 2.5 cm, Real Glass), which had the default paging per computer. The settlement can be done with mortar for glass tablets; already the grout asks for sand-free versions, such as epoxy, which is not abrasive.
Who visits this building in São Paulo is enchanted by the elegance of the entrance. I did a re-reading of the French boiseries of the 18th century, wall panels traditionally assembled with wood and reliefs, “says architect Paul Rossi. In its modern design, the panel is composed of stainless steel sheets (1.20 x 3 m, thickness 1 mm) glued to the masonry. Without machines to produce the frames, they were molded in a handmade way and then fixed with glue on the surface (execution of Qualitinox).
An unsightly staircase dominated the scene in this duplex of 90 m². So we decided to replace it with a model that really attracted attention for beauty, says architect Consuelo Jorge. She designed a whole piece of stainless steel, with 78 cm wide steps that are partially in balance (execution of the Furniture Belart). “The strength of the metal, coupled with the thickness of 1 cm of the plate, guarantees stability,” he says. Each step is configured as a French hand, screwed into the diagonal steel girder which is attached to the masonry. Handrails of the same material provide security.
Impossible not to be surprised by the lavatory created by the architect João Armentano, from São Paulo. “We cover all the walls with stainless steel, which, besides being beautiful, is resistant and hygienic,” explains the engineer Ricardo Cossermelli, Sigla Construtora, who executed the work. The plates, 2 x 1.50 m and thickness 1.5 mm, have a brushed finish (Starinox). They were glued with special adhesive on navy plywood plates bolted to the masonry. The floor has gained stone blocks of limestone bateig blue (Spring Stones).
Conceived in the 70’s, this apartment on Boa Viagem beach, Recife, welcomed visitors with a wooden door and stained glass, typical of his time. Hired for the renovation, the architects from Pernambuco Turíbio Santos and Zezinho Santos sought to print more contemporary paintings on the property. Now, the hall of the elevators exhibits an imposing sliding door (2 x 2,10 m, with thickness of 4 cm) made of wood and coated in brushed stainless steel ?? the plates of the material were glued to the surface (execution of Zé do Peixe). Pulleys that run on a hidden track in the lining guarantee the movement of the partitions.
Appliances and other stainless steel items for the kitchen are the flagship Viking brand. That is why, when he designed the store’s entrance door on a sophisticated street in the city of São Paulo, the architect Toninho Noronha designated the same material in his production. The generous measures of the pivoting piece, 2.36 x 1.88 m, meet the standards of accessibility and give it sumptuous air. As a bezel to the tempered glass plate (10 mm, from J & G Glass), there are four stainless steel profiles (Mark Steel execution). The metal also appears as a cover on the door frame. There, it remains glued on plywood plates fixed to the masonry.
Stainless steel wire mesh used to coat panels, furniture, walls and linings of internal and external areas. Manufactured by MM Fabrics, it has 1 m of width and length of up to 3 m. At Innova, R $ 130 a meter.
Made of semifinished stainless steel (alloy 304), the LR 40 tile serves as a cover, facade cladding and wall. It measures 98 cm in width, with height to order and 0,5 mm of thickness. From Perfilor, R $ 86.55 per meter.
To color the stainless steel plate (alloy 304), Inoxcolor uses an electrochemical process that creates a layer of chromium oxide and increases resistance to corrosion. It has seven tones and costs R $ 530 (the plate of 2.40 m2 and 0.6 mm thickness).
A folded stainless steel sheet makes up the Innova footer. There are versions for internal areas (league 430, R $ 16 the meter) and external (league 304, R $ 22 the meter). Measures: 5 cm high, 3.8 cm wide and up to 3 m long.
Inspired by the coatings of the academies, the Podrotatic floor (28.5 x 28.5 cm) of the Petrus line caters to the visually impaired. Da Mozaik, has a microtexturized finish and costs R $ 56 each.
10 x 10 cm inserts make up the Brushed Metalic line, manufactured by Colormix. Made of brushed stainless steel, it is welcome on internal and external walls. The 30 x 30 cm plate comes out for $ 60.
On the inserts of the Inox Premium series, from Forminox, the finish is polished and the shapes are varied. Suitable for covering internal and external walls. The plate (31 x 31 cm) is worth R $ 68, in the only laminate.
The brushed stainless steel (alloy 304) forms the Mondrian pastille, which can cover walls throughout the house, including in coastal areas, as it resists the sea air. It measures 10 x 10 cm and costs R $ 333,50 the m², in Revsteel.
Five small pieces of brushed stainless steel make up 5 x 5 cm tiles to coat internal and external walls. From the Brushed Metalic series, the 26.5 x 26.5 cm plate costs R $ 60, on Colormix.
Arabesque-inspired flower patterns grace the inserts (5 x 5 cm) of the Nouvelle line. They come in pieces of 30 x 30 cm and can be used on internal floors or walls. Da Mozaik (R $ 141 each).
Bisotê is the name of the collection of polished stainless steel inserts (5 x 5 cm), which have edges with similar finish to that of mirrors. They are found in plates (30 x 30 cm), for R $ 81 a unit. Da Mozaik.
Formica’s brushed stainless-steel laminate sheet lends itself to internal walls. It has a thickness of 1.3 cm and measures 3.08 x 1.25 m. In Single Laminates, R $ 532 per unit.
