In order to come to a conclusion regarding a better option between steel; pool fence and aluminum, one should know about the pros and cons about both. However, in the pool fencing industry, any professional would say that steel pool fencing is far better an option. Strength is a very big advantage of steel over aluminum. If you expose the aluminum fence to a lot of abuse, it will get bent and also break.
Another problem with the aluminum fence is that if there is a need of repairing damage, one has to get hold of special welding machines and it is also the case in case of customization. There are no such requirements with steel unless there is a very serious damage. Therefore, maintenance is quit easy when it comes to steel pool fencing. However, the problem with steel is that the scratches reach deep in the metal through the coating very time.
