What are the standard sizes of Aluminum sliding doors?

Aluminum doors come in different sizes, shapes and designs. The sizes and shapes of each door vary with the door type, such as sliding, folding sliding, hinged and pivot aluminum doors. The old doors come in smaller sizes, while those manufactured recently have bigger panels for larger openings. The idea of measuring the size of an aluminum door for installation is to know the overall width and height of the door. 

South African Standard Aluminium sliding door sizes

The standard aluminum sliding doors are mainly glass doors with an aluminium frame.  The South African standard height for these doors ranges between 2100mm to 2700mm whereas the width is between 1500mm and 6000mm. Standard sliding doors are usually made up of two or more parts.  For smaller doors (single sliders), there are usually two panels, one fixed panel and  a sliding panel.  The standard sizes for the single sliders range from a width of 1500mm to 3000mm.  

The medium to large standard size doors consist of four panels (double sliders).  Usually there are two fixed panels and two sliding panels.  The standard width for these doors range between 3000mm to 6000mm.  

The most common height of South African sliding doors is 2100mm.  

It is always advisable to use the standard measurement for the door frames to make things easy during replacement.

However, there is no one particular measurement for the aluminum sliding door. The sizes vary with the type of panel, as mentioned earlier. Here we are going to discuss these various panel types and their corresponding standard sizes.
