Refer to old articles of aluminium roofing sheets, they come in rolls of average of 600mm to 1300mm depends on the manufacture and specifications. As stated in previous articles, the aluminium sheets comes in rolls at the factory just like toilet rolls but with different widths and thickness based on specifications.
Calculating the roof required could be done by calculating the surface area in square meters of the area covered by the aluminium and for some companies it could be calculated in meter lengths ,knowing the width which is 600mm above as constant.
For a simple gable roof as shown in pic 1 with length of 25.2m. First you must know the height of roof from the section.
For this sample we are taken the eight to be 3meters (10 feet)to know the length of leaf “x” or “y”
Gable Roof
Gable Roof
section of roof
![[Image: sect-300x240.jpg]](http://buildingcontractorsecrets.com/wp-content/uploads/2013/03/sect-300x240.jpg)
Remember the pythagoras theorem
x2=32 +6.12
x=6.8m
Hence the area of roof is (6.8 i.e x)+6.8 i.e y) multiply by length 25.2m=342.72m2
If the width of the roof comes in 600mm or 0.6m, the length of the roof require will be 342.72/0.6m
=571.2 meters length
So for some companies they could give their quotations in meter length so just ask for the width of the rols and follow steps above.
hip roof plan fig 3
![[Image: hip-300x240.jpg]](http://buildingcontractorsecrets.com/wp-content/uploads/2013/03/hip-300x240.jpg)
For a complex roof like pic 3 above, then you can opt to do a fast estimate based on the linear area covered as shown by roof plan as it may be a bit complex and difficult, so you can divide the roof plan to sections of rectangles or squares as it may applies –(four right angles). Then add the areas together and add 10% of the same area, because the higher the roof, the more the plates , and the more complex the roof the higher the numbers of offcuts which will also increase the numbers of aluminium /plates required . So for pic 3 ,add areas of rectangles A,B,C and D which is the big center.
i.e (8.2m x 1.2m)+(1.2mx8.2m)+(1.2mx8.2m)+(22.8mx12.2m)=311.28m2
Add 10%=311.28+31.128=342m2
Now for a more accurate and scientific calculation, you must know the height of the roof , have the basic knowledge of calculating area of a triangle which is ½ base x height . And Pythagoras theorem to know the side of any triangle . Also remember the area for a rectangle is simply length multiplied by breadth.
Assuming the height of roof is 3meters as as previous in fig. 2, and taken the major part D as a simple gable roof (check the different sections on plan fig 3) and ignoring the hipped or bevelled section.
section of roof
![[Image: sect-300x240.jpg]](http://buildingcontractorsecrets.com/wp-content/uploads/2013/03/sect-300x240.jpg)
x2=32 +6.12
x=6.8m
So area of roof as previous is ( 6.8m+6.8m) multiply by length 22.8m=310m2
Add areas A,B,C
+310m2 +9.84m2 +13.44m2 + 9.84m2
=343.12m2
With your estimate is also the RIDGE and GUTTERS.
Ridge is the roof material you use that will cover and seal up the points where two leaves of your aluminium sheets meet to protect the interior from rain, it usually overlaps the two adjacent leaves of roofing sheets .
And gutter is usually underneath, it gathers rainfall and help to channel it to wherever deem fits according to design. Is at the taper ends of two adjacent leaves of aluminium sheets to collect water.

Haomei Aluminium corrugated sheet is made of aluminium and is ideal for all roofing and cladding needs. aluminium roofing sheet is easy to use, durable and economical to work with. Using aluminium for roofing has many benefits. Some of them are: Aluminium roofing sheets are extremely light with high-strength-to-weight ratio.
![[Image: IMG_4876.jpg]](http://aluminium-roofing-sheet.com/images/IMG_4876.jpg)
The Aluminium corrugated sheet metal is becoming a popular choice for use in installations and buildings. Aluminium corrugated sheet is corrosion-resistant in almost any kind of environment. Even in highly-corrosive industrial environments, aluminium roofing sheet is resistant to fumes and vapours of organic compounds and to chemicals like ammonia, carbon-dioxide and acids like hydrochloric acid, nitric acid and sulphuric acid. This corrosion-resistant property gives the metal a long life and keeps it looking good throughout its life.
Aluminium corrugated sheet-The shine and brightness of aluminium livens its surroundings and because it doesn’t stain, discolour or rot, it looks bright and shiny for a long time. Aluminium corrugated sheets can take a variety of finishes, colours and textures, which protect it and add further to its appearance.
An alumunium structure can be easily dismantled, transported and re-assembled to a new location. Though the metal is a good conductor of heat, its high reflectivity of radiant heat and light (75 to 80 per cent when new, 60 per cent after several years) keeps the interiors of an aluminium building from five to eight degree celsius cooler in summer while its low emission rate cuts heat loss during winter.
Aluminium corrugated sheet is easy to maintain and can be washed easily.

You will most often see diamond plate used in safety applications as the diamond pattern creates an excellent tread which can help reduce slips and falls. It is generally a good safety practice to use diamond plate any time people will be frequently walking over a slick metal surface.
Stairs and Walkways: Diamond plate is commonly used on stairs or ramps in industrial areas, which helps to reduce the chance of slipping on the metal. Outdoor fire exits in particular rely on diamond plate to enhance traction when the steps become slick from rain or snow.
Vehicles and Trailers: Most people with a pick-up truck can attest to how often they are stepping in and out of the bed of the truck. For this reason, diamond plate is often used as an accent on bumpers, truck beds or trailers to help reduce skids when stepping onto a vehicle, while also provide traction for pulling or pushing material on and off of a truck.
Aesthetic Accents: Aluminum, stainless steel and hot rolled steel diamond plate each have a very unique appearance and finish which can be used as an accent for architectural elements or furniture. Diamond plate can be found as runners on stairs, backslashes, table tops and more.

Diamond plate – also known as tread plate or checkered plate – has many applications across all industries. From truck tool boxes to the warehouse loading docks, diamond plate is used in a variety of industrial and jobsite applications. Normally, walking across a metal surface could result in slips and falls, but you’ve probably walked across aluminium diamond plate countless times without even noticing it. That is because of the raised diamond pattern on which acts as a tread to reduce the risk of slips. Diamond plate comes in a variety of metals, including hot rolled steel, stainless steel and aluminum and can be coated to help increase traction or polished to enhance its appearance.

How Is Diamond Plate Made?
Despite the complex diamond pattern, the process for making aluminium diamond plate is relatively simple. When making standard aluminium plate oraluminium sheet, the material is brought through a series of large rollers until the desired thickness is achieved. However, there is one major difference when making aluminium diamond plate. On the final set of rollers, one of the rollers has a pattern which embosses the diamond shape onto the plate. If you look at mostaluminium diamond plate, you will notice that only one side of it features the diamond pattern. This is due to the fact that only one roller in the set has the diamond shaped pattern on it, so one side of the metal is exposed to it while the other is left smooth.
For aluminum, this process “stamps” the pattern onto the plate, whereas with steel, hot rolling is generally used. This involves heating a slab of steel above its recrystallization temperature and then bringing it through a series of smooth rollers to its desired thickness. Heating the metal above its recrystallization temperature helps to prevent major alterations in mechanical properties due to work hardening. Once the material has reached its final shape, it is allowed to cool slowly.
While there are other techniques used to create diamond plate, the rolling method is most common because the only major difference between rolling plate and diamond plate is the roller used. This makes the process very economical, and it is why diamond plate can often be found at relatively affordable prices when compared with a normal plate of the same material and dimensions.

Diamond plate Diamond plate, also known as checker plate, tread plate[1] and Durbar floor plate, is a type of metal stock with a regular pattern of raised diamonds or lines on one side, with the reverse side being featureless. Diamond plate is usually steel, stainless steel or aluminum. Steel types are normally made by hot rolling, although modern manufacturers also make a raised and pressed diamond design.
The added texture reduces the risk of slipping, making diamond plate a solution for stairs, catwalks, walkways, and ramps in industrial settings Its non-skid properties mean that diamond plate is frequently used on the interior of ambulances and on the footplates of firetrucks. Additional applications include truck beds and trailer floors.

Diamond plate can also be used decoratively, particularly highly polished aluminum variants. Manufactured in plastic, diamond plate is marketed as an interlocking tile system to be installed on garage floors, trailers, and exercise rooms.
Diamond plate may be used for surface protection against damage from foot traffic or harmful chemicals. Manufactured with polymer variants, inter-locking diamond plate tile is used in areas with high surface-erosive traffic.
Tata Steel marketed the plate as Durbar Plate.
"Diamond plate " can also refer to similar anti-slip textures.[citation needed]

xcept thickness, width and length, there are still many other aluminum sheetmeasurement standards. The number which is closely connected with thickness is the aluminum sheet metal thickness tolerance. Generally speaking, the smaller the thickness tolerance is, the higher the aluminum sheet quality is. In haomei Aluminum, we always work hard on improving our technology. Now, the thickness tolerance can reach to ± 0.005 mm in our company.
aluminum sheet metal thickness
After determining aluminum sheet metal sizes, next standard is aluminium sheet grades. There are mainly 8 aluminium alloy series. The more commonly used aluminum sheet are 1000, 3000 and 8011. This three aluminium alloy sheet are all provided in haomei Aluminum.
The third standard is the temper, which means the difference of aluminum sheethardness. The main product of haomei Aluminum is H temper. H indicates the aluminum sheet is strain hardened during the production process. In addition, there are two or more numbers following the H letter, which means the different digits of strain hardening.

| What material is aluminium foil made from? |

Posted by: aluminiumsheet - 08-27-2018, 06:42 AM - Forum: aluminium faq

Aluminium foil (or aluminum foil), often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.
In the United States, foils are commonly gauged in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated to other materials such as plastics or paper to make them more useful. Aluminium foil supplanted tin foil in the mid 20th century.
Annual production of aluminium foil was approximately 800,000 tonnes (880,000 tons) in Europe and 600,000 tonnes (660,000 tons) in the U.S. in 2003.
Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products, and 25% used for industrial applications (e.g. thermal insulation, cables and electronics). It can be recycled.
In North America, aluminium foil is known as aluminum foil. It was popularised by Reynolds Metals, the leading manufacturer in North America. In the United Kingdom and United States it is, informally, widely called tin foil, for historical reasons (similar to how aluminium cans are often still called “tin cans”). Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium. In Australia, aluminium foil is widely called alfoil.
What is the production of thin aluminum foil?
A sheet of aluminium foil
Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner.
The continuous casting method is much less energy intensive and has become the preferred process.
For thicknesses below 0.025 mm (1 mil), two layers are usually put together for the final pass and afterwards separated which produces foil with one bright side and one matte side.
The two sides in contact with each other are matte and the exterior sides become bright; this is done to reduce tearing, increase production rates, control thickness, and get around the need for a smaller diameter roller.
Some lubrication is needed during the rolling stages; otherwise, the foil surface can become marked with a herringbone pattern. These lubricants are sprayed on the foil surface before passing through the mill rolls. Kerosene based lubricants are commonly used, although oils approved for food contact must be used for foil intended for food packaging.
Aluminium becomes work hardened during the cold rolling process and is annealed for most purposes. The rolls of foil are heated until the degree of softness is reached, which may be up to 340 °C (644 °F) for 12 hours. During this heating, the lubricating oils are burned off, leaving a dry surface. Lubricant oils may not be completely burnt off for hard temper rolls, which can make subsequent coating or printing more difficult.
The rolls of aluminium foil are then slit on slitter rewinding machines into smaller rolls. Roll slitting and rewinding is an essential part of the finishing process.
Properties:
Microscopic close-up of aluminium foil on the back of an intumescent rubber strip.
Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.
Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the aluminium sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe (wrongly) that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation. Increased reflectivity decreases both absorption and emission of radiation. Foil may have a non-stick coating on only one side.
The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.
