Not only should a building be comfortable and pleasant to work in, but it should also convey the right image of the business that occupies it. Architects and designers have turned to perforated metal to achieve this end.
Stoddart manufacturers perforated metal products combining design creativity with strength, precision, versatility and functionality. Facades, balustrades, false ceilings and the use of perforated screens for decoration are just some of the examples of use for Perf Art. The characteristics of perforated metal can assist to create just the right setting for the facade, the lobby or any part of the structure that utilises perforated sheets. It allows the determination of the desired amount of light coming into the building, creating separate working spaces without giving a closed-in feeling and, using the right open area, has significant acoustic qualities. It also has energy efficiency application for control of solar heat gain and air conditioning reduction.
Naturally, behind the scenes, the use of Perf Art is extensive as well, with gates, barriers and screening helping to make buildings a safe and pleasant working environment. Stoddart offers a wide range of standard as well as customised perforated metal sheets in steel, stainless steel, galvanised steel, aluminium, copper, brass and many other materials. Stoddart Perf Art is extensively used in engineering, building, architecture and landscape situations.
Stoddart Perf Art can be an abstract design, a company or brand logo or even a photograph — anything you can imagine. Perf Art is created by punching different sized holes into metal to represent the various different shades within the image. Detail in the perforated image is determined by the size and spacing of the holes in relation to the surface area.
Images can be made to fit an individual panel, or can be perforated for an image over a larger area made up of a number of panels. This can produce building cladding or plant screening to spectacular and very individual effect. When back-lit, either by natural light, or by diffused LED lighting, panels take on a whole new life, transforming the environment where they are displayed. Utilised to add unique, durable image-based facades to new and existing structures or providing a sunscreen to reduce energy consumption, this exciting technology can be applied to a range of different materials and finishes for both interior and exterior applications.
The nature of the precision manufacturing processes used in metal perforation enables complex designs to be accurately rendered within perforated facades. This allows the incorporation of geometric shapes, graphic designs and perforated representation of photographic images. This may be used for dramatic effect or to reflect a design theme, an aspect of a building’s use or its surrounding environment. In some cases, the perforated material performs the supplementary function of solar shading; in other applications, reducing solar gain may be its primary purpose.
Stoddart can incorporate precision-perforated metals within building facades that allows architects and designers to not only create unique decorative designs and aesthetic effects, but also offer practical solutions for issues such as solar shading and sound management. As part of a lightweight cladding system, perforated materials can be used to provide more pleasant internal environments and reduce energy consumption by allowing natural ventilation and daylight to enter while shading spaces from direct sunlight. They can also improve building security, or be combined with sound-absorbing material to enhance acoustic performance.
Perforated facades can be created from many different metals and Stoddart offers a range of finishing techniques such as bending, rolling, forming, coating or anodizing. The shape, size and pattern of the holes in a perforated material can all be specified during the manufacturing process to meet a project’s exact requirements. In addition to complex graphic and picture perforation, a range of standard perforation patterns, hole shapes and configurations can also be selected, which are produced by standard tooling. This approach is often used for projects where individual design and aesthetics may not be primary considerations, such as public transport shelters, car parks and security applications, as well as balconies and balustrades.
Stoddart can arrange for installation of customised and standard panels and framework. Stoddart works closely with Architects, Engineers and builders to ensure correct fixing and construction. Stoddart has a team of design draftsmen who consult from the moment of conception through to completion of the project.>
Metal Finishes & Anodizing
Stoddart Architectural can apply powdercoating for a high-quality finish that lasts longer and is more durable. Powder coating is a green technology as it contains no solvents and therefore does not emit volatile organic compounds (VOCs) norhazardous air pollutants (HAPs). They provide a tough, anti-corrosive finish that protects and decorates the subject and can have more durable powder coating that allows the simple and rapid removal of most forms of graffiti, reducing overall maintenance costs and ensuring the appearance of powder coated surfaces are maintained.
Powder coating is a type of dry coating, which is applied as a free-flowing, dry powder. It is used to create a hard finish that is tougher than conventional paint. Powder coating is mainly used for coating of metals, such as galvanized steel and aluminium extrusions. Advantages of Powder Coating include: 1) Powder coatings emit zero or near zero volatile organic compounds (VOC); 2) Powder coatings can produce much thicker coatings than conventional liquid coatings; 3) Powder Coating is available in an anti graffiti specification; 4) Powder coated items generally have fewer appearance differences.
Anodising is the process by which the natural film on aluminium is greatly increased in thickness. Aluminium metal is on the anodic side of the galvanic series. Its position is similar to zinc and magnesium, ie it is readily oxidised. The oxide on aluminium is naturally corrosion resistant, very hard, abrasion resistant, an insulator and very tenacious. In its natural form the oxide film on aluminium is less than 0.50 microns thick.
Because the naturally occurring film is very thin and attached to a soft ductile metal, it is easily damaged. Building up this coating provides very useful properties for the aluminium surface. Anodising produces a high specification metallurgically bonded finish that resists corrosion, abrasion and exposure to industrial, marine and other severe environments.
New South Wales
Recent winners of the ASSDA 2017 Fabricator of the year Award for this project, Stoddart worked alongside CPB Contractors & others on the creation of the Wynyard Station Walkway and Clarence St station entrance. Over 1,600m2 of perforated metal was incorporated into the design, equating to over 1,500 panels to create this aesthetically pleasing winding walkway between Wynyard Station and Barangaroo in Sydney’s CBD.
The stainless steel panels supplied by Stoddart were both for internal and external application in the façade of the new entrance in Clarence St and the internal fitout of the new portal entrances and tunnel lining works of Stage 4, Clarence St. The intricate pattern required were all executed within Stoddart’s factory in Karawatha, Brisbane. The design work was completed wholly on CAD and Solidworks to ensure each panel fitted exactly into the pattern and alongside each other with precision, with all panels then manufactured completely in the Brisbane facility.
The project was the first stage of a $160 million upgrade of Wynyard Station. The station now features wider access points as well as new entrances from Clarence St and Kent St to Wynyard Station.
Stoddart Infrastructure were commissioned by Adelaide Airport to design, fabricate, and install several walkways as part of the 2019 centenary celebrations of the first flight from England to Australia in 1919.
The custom walkways are based on the Stoddart Infrastructure Decco walkway and feature integration of custom perf art mesh panels with travel-themed motifs between the posts, providing fantastic visual interest to the canopies. Additionally, LED courtesy lighting was added for patron comfort.
Gold Coast Light Rail
Stoddart designed and installed multiple Perf-Art totems for the Gold Coast Light Rail project. The image selection was proposed by Stoddart to CPB contractors with meetings taking place to finalise design between Stoddart & CPB’s Landscape and Urban design teams. A variety of native flora specific to each participating station was selected as the final designs for the totems. The completed totems were made from 3mm thick aluminium, powder coated using Dulux Electro colours. They each had an approximate diameter of 500mm with varying heights from 2.6m – 2.8m.
