If you find it difficult to locate a welder that fabricates iron doors or the ones being fabricated is below your standard, you can opt for the choice of making one for yourself.

Though the option of fabricating your own iron door has to go with a huge price and you must have had some level of welding and skill. The price of fabricating yours may be higher than the ones being sold in the market but the advantage is ensuring the quality is up to your taste and the design and surface finishing is according to your choice.

There is no fixed price for an iron door. The price is determined by several factors such as size, design, surface finishing, type of iron, iron thickness, foreign iron door or locally-fabricated iron door, and the welding/fittings quality.

Normally, locally fabricated iron doors cost from N25, 000 upwards while foreign ones cost from N45, 000 upwards. The price of the one you see can be altered due to mentioned factors as well as your location.


Assuming you have made the decision to fabricate your own iron door, sometimes this will become necessary because of the unusual door space in your building which could not be seen from the sizes of already made iron doors in the market. However, whatever be the reason let us discuss how you should go about it:

  1. Use drawing materials to draw the door. An example is using a pencil and eraser to draw the door on a piece of paper.
  2. Indicate the dimensions in the drawing according to the measurements obtained from the door space in your building.
  3. Make the proper design that you desired on a piece of paper such that the design still retains the dimensions and total measurements taken earlier.
  4. Make a proper material selection for the door according to the money in your pocket. At this stage, you can choose the iron thickness, the iron framing bar sizes, etc.
  5. Hire space in a workshop as well as their machines and equipment to carry out your fabrication job.
  6. During fabrication, cut the iron bars for framing first according to measurements specified on paper. Afterward, cut the outer frame bars that will be fixed on the door space as well.
  7. Now you have two frames bars for the door one is for the outer frame that will be fixed inside the door space while the other will be the door carrier for opening and closing.
  8. Using a T-square or angle bar, start joining the iron bars as specified in the drawing and use the square to ensure that their joining maintain the mandatory 45dgrees space. This will ensure that the frame is squared after fabrication.
  9. First of all, start tap the electrode on all the joints to hold them temporarily and then take the measurement again to ensure that everything is in its supposed position before running a full welding operation on the joints.
  10. Repeat the process specified in step 9 in all joining processes until you have successfully formed the entire shape of the door.
  11. The next stage is to use filler to fill up spaces, errors, and use a filing machine to smoothen the rough surfaces.
  12. Afterward, use special car paints and reflective paints to give the door the surface finishing you desired.

At this stage, you have successfully made your iron door. Once the paint dries up, you are free to go ahead and install the door in your building.
