Along with the development of the era and the more advanced technology, scientists and engineers continue to develop a variety of construction materials that are easier and cheaper, one of which aluminum materials are often used as door frames and windows.
Humans have long used wooden frames since these materials are easy to find and easy to do, but because of the increasing human population that has an impact on the increasing need for timber as a variety of purposes makes for massive deforestation.
Due to a large number of forests destroyed by the increasing need for timber, it causes environmental damage that can destroy the ecosystem of living things.
Scientists and engineers have to think hard to overcome a destruction of the environment by creating alternative materials that can be used for wood substitutes.
Alternative materials that can eventually be accepted by audiences such as aluminum. Actually, aluminum is widely used in construction work such as aluminum formwork and aluminum frame.
Aluminum frame is a kind of alternative material that is considered environmentally friendly and durable so that today many homes and various types of buildings utilize this type of frame.
Should we know more closely with the aluminum frame.

Aluminum itself is a type of metal that is widely contained in the earth including a good type of electrical conductor. Aluminum can be processed into various shapes with ease either sheets or profiles.[source]
Due to its lightweight and easily formed nature, aluminum is also used as a plane, beverage and so on.
Previously aluminum is an expensive type of metal because the electrolysis process has not been found. Electrolysis is the process of decomposing electrolytes by utilizing electric current.
The process of electrolysis was investigated by Sir Faraday in the early 19th century, the observations made in 1833 produced a useful summary in the future.[source]
Charles Martin Hall and Paul L.T. Heroult eventually found an electrical process in 1886 that could reduce the cost of aluminum production [source]. The findings made them instantaneously rich.
Actually, in 1825, sir Orsted had managed to separate aluminum from its compounds by reducing aluminum chloride and finally perfected by sir Wohler in 1825 in powder form.[source]
Stages of making aluminum.[source]
- The Bayer process, a process to purify bauxite ore.
- The Hall-Heroult process, a process for producing pure aluminum.
Excess aluminum.[source]
- Can replace the function of iron with 95% aluminum alloy and 5% other elements.
- Has a fine powder and shiny like the original metal.
- Not affected by acids or other chemicals.
- No need finishing work, such as paint and others
- Hold down termites.
- Good electrical and heat conductor.
- Has a durable color.

Currently in Indonesia, especially Aceh quality wood is increasingly scarce due to government policy that prohibits illegal logging causes many people choose alternative material to replace wood, especially aluminum frame.
Aluminum frames have advantages among them.
- Cheap.
- Anti-fire.
- Environmentally friendly.
- Does not require special treatment on finishing work.
- Durable.
- Hold rust and termites.
But this type of frame type also has shortcomings among them.
- Have a limited model.
- Because utilizing the Fischer system and the screw to the wall make you have to be careful when installing.
- It takes a skilled worker to avoid problems later on.
In the installation work of aluminum frames required sealant that serves as a glue between the profile and the glass so as not to get out of the frame also adhesive between the frame.
How to calculate the need for labor and material on the work of aluminum door frames as shown below?
To complete a work of aluminum frames like the picture above then you have to calculate a total length of the frame.
Is known
| Items | Information | Amount |
|---|---|---|
| High | 2.60 x 2 units | 5.20 m |
| Wide | 1.35 x 2 units | 2.70 m |
| Length + Height | 5.20 + 2.70 | 7.90 m |
In accordance with the technical analysis of Indonesian National Standard [source], to complete 1 m of aluminum door frame installation is required.
Labor
| Information | Amount |
|---|---|
| Workers | 0.0430 Person per day |
| Blacksmith | 0.0430 Person per day |
| Foreman | 0.0043 Person per day |
| Overseer | 0.0021 Person per day |
Material
| Information | Amount |
|---|---|
| Aluminum profile | 1,100 m |
| Screw fixer | 2,000 pieces |
| Sealant | 0.060 Tube |
So to complete 7.90 m aluminum door framing job is required.
Labor
| Items | Information | Amount |
|---|---|---|
| Workers | 0.0430 Person per day x 7.90 m | 0.224 Persons |
| Blacksmith | 0.0430 Person per day x 7.90 m | 0.224Persons |
| Foreman | 0.0043 Person per day x 7.90 m | 0.022 Persons |
| Overseer | 0.0021 Person per day x 7.90 m | 0.011 Persons |
Material
| Items | Information | Amount |
|---|---|---|
| Aluminum profile | 1,100 m x 7.90 m | 5,720 m |
| Screw fixer | 2,000 pieces x 7.90 m | 10,400 Pieces |
| Sealant | 0.060 Tube x 7.90 m | 0.312 Tube |
The standard weight of one tube sealant on the market is 500gr or 0.5 kg
Aluminum is a type of metal that has long exploited by humans and previously had a very expensive price, until the discovery of electrolysis process.
As an alternative material of wood replacement, aluminum frame is considered more environmentally friendly, cheap and durable, so scientists continue to develop this type of material in order to be exploited wisely.
We recommend you entrust the work of the installation of aluminum frames on trained workers to produce a good frame.
| Items | Amount |
|---|---|
| Workers | 0.224 Persons |
| Blacksmith | 0.224Persons |
| Foreman | 0.022 Persons |
| Overseer | 0.011 Persons |
| Items | Amount |
|---|---|
| Aluminum profile | 5,720 m |
| Screw fixer | 10,400 Pieces |
| Sealant | 0.312 Tube |
This calculation is only an example and can be used by anyone, this calculation is in accordance with technical analysis of Indonesian National Standard and can be developed in accordance with the needs of the field.
This is the only thing I can write on this occasion, over all the mistakes and lack of unintentional writing as a servant of God, I apologize.
Thanks to friends who have visited this blog and provided constructive comments, as well as scientists who are willing to sacrifice their time for a better civilization.
