How to remove steel door frame threshold?

[Jerdelp87]

The door from my garage to my house has this bottom rail or threshold as part of the steel door frame.

It is ugly and a bit of a trip hazard. Also, the tiles on the end keep getting chipped.

It is a single brick wall 

Is it ok to use an angle grinder to cut out the threshold? Or is it required to keep the frame structural or for fire safety?

My plan was to cut it out, level with concrete and extend the tiles to the end where it steps down to the garage floor. I was going to add a weather seal to the bottom of the door. 

No other doors in my house have this sort of threshold.

Hello @Jerdelp87 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your steel frame door. 

Although it is technically possible to cut down your steel frame, I would advise to do a bit of investigation first in regards to your steel frame door. It could be a fire safe door, or the door frame needs to be like this due to its classification. It must be able to carry a certain amount of weight and cutting the frame could compromise its integrity. If you are living in an apartment complex, I recommend speaking to the building manager in regards to the door frame. You could be in particular fire zone and door needs to seal against the frame.

Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.

If you need further assistance, please let me know.

Good Evening @Jerdelp87 

My thoughts parallel @EricL's and the main one is the seteel structure is sound as is, If you cut the base you are weakening the overall rectangle that is supporting the door and possibly doing double play as a lintel across the top of the door as well. I would get a professional opinion on seeing if its a feasable project to replace the steel frame/cut it.

Hi @Jerdelp87 

as with both @EricL and @Dave-1 my only concern would be if it compromises any fire-safe entry. Insurance companies will look at anything even non-related not to pay out should something happen.

That aside, I would be quietly confident that you could cut the sill out and replace it. Making the difference with concrete and tiles would be adequate as long as you tie in the side frame in to the design.
