Decking is corrugated sheets of black or galvanized steel or iron with a thickness of 1.0-1.8 mm. Corrugated iron is made from cold-rolled sheets between two shaped rolls or stamping on mechanical presses. To avoid excessive stretching, the waves of the sheet are formed one after the other. For this, the rolls of the mill are shaped so that the waves are distributed along their axes. Sheets are usually moved between rolls in a transverse direction. The presence of corrugations gives the corrugated gland significant strength, especially in bending during operation. Corrugated iron is used for wingless coverings of industrial buildings, vaults, gutters and railways, as well as for field defensive work (light vaults covered with a protective layer of earth).

Galvanized iron is iron that is coated with a layer of zinc to help the metal resist corrosion. Steel can also be galvanized. When the metal is to be used in an environment where there is a possibility of corrosion, it is often galvanized to prevent this process. However, even with galvanizing, corrosion will eventually start to occur, especially if the conditions are acidic.
There are two main methods for making galvanized iron. The most common is hot-dip galvanizing, in which iron is moved through an extremely hot bath of molten zinc, which can be mixed with a small amount of lead, depending on the circumstances. When the iron is released from there, the zinc will combine with it, creating a layer on its surface. Sometimes the metal can be passed through the mill to level the coating. Another method that can be used is electrodeposition, also known as electroplating, although this is rarely used. Galvanized iron can be used to make pipes.
After galvanizing, the iron is sprayed on, which can range in color from shiny to dull gray. If desired, zinc can be colored or left in its natural shade. Coloring is often done when the iron needs to match other building materials, or when people want to make it more original. For example, in a garden, iron can be painted green to blend in with the foliage.
As long as the zinc coating remains intact, the galvanized iron should remain in relatively good condition.However, acidic conditions can degrade zinc over time, creating areas where corrosion can occur. It can also occur through penetration into the coating, such as when someone drives a nail through a galvanized iron sheet, triggering chemical reactions between the elements inside. Once corrosion begins, it can spread beneath the zinc, eventually leading to the destruction of the metal.
This type of iron is widely used in pipes, stakes, sheets, and wire, as well as other formats. Many household and household goods contain galvanized iron products and may, if necessary, have non-standard sized parts. People sometimes turn to professionals who weld or cut galvanized iron to fit a specific project.
For many people, the term "corrugated iron" instantly evokes the image of tattered barn roofs, a bare industrial headquarters, or harsh Scandinavian houses. Fair enough considering its seemingly exclusive use as a durable and practical building material. The past decade has seen an increase in the use of corrugated iron in residential properties around the world.
Unlike low-cost alternatives such as aluminum and vinyl siding, which seem to be installed in poorly designed buildings until it was too late to correct technical flaws, the expanding corrugated iron market was largely slow-growing and deliberately created. Consumer concerns in the housing market have created a bottleneck in architecture in the sense that there is only a list of companies that can consistently meet people's expectations.
In addition, there are only a few consumer groups who are open to the idea that corrugated iron is part (or whole) of their new home. But corrugated board turned out to be better than other cheap building materials.

In the early 20th century, newly built apartment buildings made of corrugated iron were in short supply, but survived after several years of exhibitions demonstrating the versatility of the material. During this time, corrugated iron became synonymous with war materials: in 1916, Peter Nissen's name entered the English language when he designed a semi-circular hut from corrugated iron sheet. By the end of World War I, over 100,000 Nissen huts harbored over 2,500,000 Allied troops. The Americans have developed their own version of such a building - the Quanset hut. And some of the largest metal structures were built to house the ill-fated new airships, whose fate was decided by the Hindenburg disaster in 1937. The Germans even developed corrugated metal aircraft like the Junkers 'J1'. The British responded in World War II by building 2,000,000 corrugated iron bomb shelters in their gardens.
In more recent times, corrugated metal sheets provided refuge for millions of people in the barrios, huts, and cannonville (canonville is the French name for the corrugated metal drum) that grew up around the metropolitan areas of South America, Africa and Asia. In disaster areas, metal sheeting is still the ideal material: it is easy to transport, it is light, it can be installed by unskilled personnel, it can bear the weight of snow, it is perfectly protected from cold and heat, it resists fire and sells well in the market because it performs well their tasks.
Remarkably, corrugated sheet metal is back in fashion. In the 1920s, architects such as Walter Gropius and Buckminster Fuller experimented with the material.In the 1950s, sleek and sleek, it suited Palm Springs 'desert modernists' and California's avant-garde architects. Pierre Koenig's Stahl House has made this utilitarian material charming again. From this Californian ancestry, Frank Gehry emerged with his distinctive style of distorted sheet metal; and arguably the most influential and iconic building of the late 20th century, the Guggenheim Museum in Bilbao.
Australia remains a spiritual home of corrugated iron. It has even gained acceptance in Aboriginal communities who regard the leaves as "artificial bark" that lightly touches the ground. No one has done more than Australian architect Glenn Murcutt, a 2002 Pritzker Prize winner who hired corrugated iron to serve world-class architecture.
More efficient manufacturing allowed iron sheets to be massively sold and widely distributed in the early years of the Industrial Revolution in Britain. Events such as the California and Australian Gold Rush and World Wars I and II accelerated the rise in popularity and demand for cheap, durable materials that could be easily transported - corrugated iron fit the bill.
If you go back to the 21st century, you will notice that the introduction of corrugated iron into residential real estate is not so rare. Take the award-winning architect Glenn Merkutt, for example. Mercutt has made a world-renowned name for himself thanks to his particular focus on the topography and climate of the regions in which he operates.
The unique ability of corrugated iron to resist temperature changes allows the interior to maintain a constant internal environment even in extreme heat conditions, while its non-combustible property only adds to the practicality of the material. Architects now understand, perhaps more than ever before, that the use of materials that are resistant to extreme and unpredictable weather conditions is just as important as their corrosion resistance.
The subtle balance of wood and iron used in the design of the Iron Maiden house gave the hard lines of the exterior a satisfying texture. The upright wooden planks at the entrance, along with continuous sheets of corrugated iron, draw the eye upward, while warm tiles are used at the rear of the house to offset the geometric structure of the iron.
The HHF Architects project consists of four boxes connected by small aisles, all in an iron appearance, compared to the lush greenery of upstate New York. The Tsai Residence and accompanying guest house, commissioned two years later, show how simple architectural design is supported by inexpensive materials.
Shoreham House was a successful attempt to transform a previously dysfunctional home into a well-maintained, sustainable and practical design. Long sheets of iron siding complement the whimsically built and low-lying dwelling, while large double-glazed windows open up the interior.
Situated along the shores of Lake Femunden in southern Scandinavia, this charming structure was originally two small log cabins. The now connected cockpit is on a cantilever deck and is accompanied by an overhanging corrugated steel roof that has created a sheltered outdoor space (translucent panels have been added in some areas to maximize light inside the cockpit). The objective of the project was to “carry out traditional construction work and initiate a dialogue with the boarding management”.
The Seal Rocks House Two is located among the trees south of the coastal town of Forster, Australia. The simple structure mimics the retro feel of early modern construction, but at the same time it represents many of the simple architectural techniques that dominate this part of the country.
Inland House can be interpreted as a “modern farmhouse” that seems appropriate for its location, as housing is hidden from human eyes in a valley in Auckland, New Zealand. Corrugated iron siding was chosen exclusively for the tallest part of the three structures and balances the sleek look with rustic materials.
The sheet steel is immersed in a bath of dissolved zinc, and its surface is coated with this compound. Continuous galvanizing machines are popular nowadays. This means people put a steel coil in a zinc-dissolving bath to make galvanized steel.
Steel is also hot dipped. But after leaving the zinc bath, it is immediately heated to 500 degrees, which creates a thin film of an alloy of zinc and iron. This is the main difference between galvanized corrugated board and alloyed galvanized steel. It has good adhesion and welding properties.
The electroplating process is very convenient for the production of electroplated sheet. But the clad layer is too thin to resist corrosion.
Galvanized steel is finished only on one side of the material. Compared to galvanized steel on both sides, this type of corrugated board is much better welded, painted, rust prevented and processed.
Bearing corrugated board is a material that is used for roofing work. Its feature is a thickness of 0.5 millimeters, deformation stability and ease of attachment.
