How To Order

Our steel doors and frames are easy to order. Simply follow the steps below for great looking internal steel doors

Step 1: measure your opening

When measuring the size doors you would like it is important that you use an accurate tape measure and that openings are square. Be prepared to be exact and provide measurements in millimetres (mm). Okay, here we go!

Measure the overall width of your opening. Measure the width in 3 locations, top, middle and bottom of your opening.

Next, measure the overall height of the finished opening. This is from your internal floor (tiles/wood/or carpet) to the ceiling. Measure the height in 3 locations left hand side, centre and right hand side of your opening.

Use the smallest measurement taken for both the width and height measurements to calculate the size of your doors. Subtract 10mm and this will give you your manufacturing sizes. 


PLEASE NOTE, Our guidelines for measuring assume that your opening is square and plumb. The team at SteelDoors.Online assume no responsibility should doors and/or screens be ordered to the wrong size due to measuring errors by customers. If you are uncertain if your opening is square we advise to consult a skilled tradesman to measure for you.

Step 2: choose your doors


1. Our online shop allows the choice of 5 super popular colours to choose from.

2. Next to choose is how the doors will operate. For a sleek look choose a slim Pull Handle and magnets. For a robust latch system opt for a Lever Handle. If you would like a traditional design then the T-Bar handle is for you!

3. Kick plates are low level steel panels that replicate the Original Steel Door style. Choose from 200mm or 500mm kick plates.

We are almost there….

4. choose the door swing orientation. On single doors this refers to which way your door will swing. For double doors this refers to which door will be the first opening door. Picture yourself standing in front of the door. The doors will open toward you. Decide which way you would like the door to operate.

5. Finally, input your manufacturing sizes. As described above, this is the measurement you have calculated and includes the door and door frame. 

We offer doors up to a maximum width and height. Should you have sizes outside of this range then no problem. Shoot us an email and we can assist you. 

If you are joining doors and fixed screens together to make a partition please describe this and include which side the fixed screen is to be on in the ORDER NOTES box in the cart section when placing an order. REMEMBER doors are always viewed from the hinge side.
