Aluminium vs Stainless Steel Gate


















 As the population increase in Singapore, security can become a major challenge in homes. Therefore, gates play a vital role in ensuring safety in our homes and business premises. Gates are designed from a variety of materials such stainless steel and aluminum. In this article, we are going to make a comparison of some aspects between Aluminum vs Stainless steel gates. 


Rust

Aluminum 
When it comes to rust, aluminum is not affected. Therefore, exposure to moisture is not an issue to aluminum gates. In places where a gate is exposed to elements such as moisture and oxygen, you will have no need to worry about rusting. The ability of aluminum to resist makes it more durable than stainless steel gate.

Stainless steel
When exposed to oxygen and water, steel will rust. If you are near the coast, where there is the presence of salt, the iron will rust quickly. Usually, the rusting of iron is prevents through galvanization. However, this often fails at holes, joints, and seams where the coating has been pierced. In most cases, the moisture and oxygen are trapped inside, and the gate will rust from inside. In this case, aluminum gates have a shorter lifespan when compared to aluminum gates.

Safety 

Aluminum
Aluminum is light and cannot make a significant impact when it comes in contact with the object or persons. Therefore, aluminum is safer and cannot cause serious injuries on impact with individuals or objects. Installing aluminum gates in your home or business premises will give your no worry about the safety of your pets or kids during the opening and closing of the gate.

Stainless steel 
Stainless steel can triple the weight of the aluminum. When swung open, this massive structure can pose serious hazards to anyone that gets in its way. Moreover, stopping a stainless steel gate can be very harder hence more dangerous. The heavyweight steel gate at your home can pose more danger to your family and pets during opening and closing of the gate.

Automation 

Aluminum 
Aluminum is easier to automate than stainless steel. Its light weight allows the motor to work with little effort and last longer. In this case, the gate requires less expensive gate openers due to its light weight. Aluminum will not put much strain on the gears to stop the gate in motion. Also, the aluminum gate will not bend when it is hit by an obstacle it has less likelihood of bending hence less damage to mountings for gate opener.

Stainless steel 
Heavy-weight is the most limiting factor to the automation of the steel gate. In this case, you will need more advanced and sophisticated gate openers. Moreover, the heavy weight of the stainless steel gate will put much strain on the gears making it had to stop the gate in motion.



DIY installation 

Aluminum 
Aluminum is light weight making the drill work easier. Lifting the gate in place will not require a team of laborers. In fact, two people can easily lift the aluminum gate and put it in place to the required position. When fitting the gate with gate openers and accessories, one bit will be enough for drilling work. Since the aluminum gate installation requires less manpower, the installation is also cheaper compared to the stainless steel gate.

Stainless steel 
The heavy weight makes the installation of the stainless steel a difficult task. Positioning the gate to the position is a daunting task and requires many people for the job. In most cases, it requires up to 20 people to install the gate- the work that could have been done by 2 people for the aluminum gate. Moreover, drilling work is the biggest headache for installing this gate as the drill bits are made of steel. Moreover, the installation of stainless steel gate is more expensive due to more manpower required for installation.

Coating 

Aluminum
Coating an aluminum gate is easier and can be done with specialized durable powder that creates a thin layer of a protective coating. In this case, the aluminum gate can be coated to match your desired style. In this case, it will be much easier to customize the color of your aluminum gate to need to meet your needs.

Stainless steel
Stainless steel gates cannot be easily painted to meet your desired needs. In most cases, the stainless steel has to be powder coated to prevent exposure to rust. The standard coating powder looks nice when finished, but can look ugly when chipped or scratched.

It should be noted that coating powder is not paint and can get heated into a shell. However, there is no successful way to touch up the gap which results from cracked off shell. For steel gate, you will need a regular checkup to avoid “rust smacking”.



Material resilience 

Aluminum 
The 6060-T6 aluminum is a high-quality has yield strength of up to 35,000 pounds per square inch. In this case, the aluminum is much stronger than stainless steel that has yield strength of about 25,000 pounds per square inch. In this case, aluminum gates absorb pressure without distorting its shape. Moreover, aluminum resists snapping because of its high level of flexibility – like that of an airplane wing. The aluminum yields to pressure exerted on it and regain its original form when the pressure is released.

Stainless steel 
Bending and denting is a common problem with stainless steel. However, the steel has to be thinner to prevent denting. Steel does not resume shape after exerting the pressure. In this case, the steel gauge should be higher to withstand denting. As the gauge goes up, the weight and cost also rise. In this case, the ease of installation and safety goes down.

Moreover, some costs associated with denting of the stainless steel gate can be overlooked. In this case, the brackets for automation have to be placed in exact positions. Denting shift this placement leading to broken parts and more stress. Also, weight is a factor that leads to an increase in momentum that increases the force when the gate hits something. In this case, the yield strength of the stainless steel is much lower than that of the aluminum gate.
