Will this frame hold a 20kg door?

[jacoscar]

I have built a frame for two doors, one 686mm and a 306mm, out of 20mm thick planed timber; the width is about 145mm
The timber studs are 4x2
Having just received the doors, I realised how heavy they are, especially the bigger one (20kg)

The door will be hang on this side, where the frame is about 3cm proud of the studs and it’s where I fear it might flex too much. Should I put some kind of reinforcement?

Will this hold the weight of the door and not bend?

No problem.But finish making good to brickwork first.

normally i would suggest not a good idea and likely to give trouble because 20mm -1.5mm for the hinge leaf sunk in only leaves 18.5mm [3/4"]for the screw to grip so just over half the normal 30.5-32.5mm timber available for grip
now in your instance at least 2 off the 4 screws in the hinge will go full through into the stud with another 2 close to the edge possibly breaking out dependant on stud set back from the door lining so just about enough support to be 100% confident rather than 50-65% confident off no problems with 18.5mm/3/4" screws securing

The stud set back from the lining is 30mm so no screw will go into the stud

get some timber into the set back in the hinge area well glued and screwed in 'cut your plasterboard around it and just make sure your architrave will cover it
and make sure you wont get clashing between fixing screws and hinge screws and pilot all holes in the block and hinge to prevent splitting ??

Will do, the additional timber should also prevent the frame from twisting under the weight of door (if butted up to the wall, I’ll probably have two layers of plasterboard)

as an aside

dependant on hinges you use most old door and window furniture [hinges latches'handles]is set up for no7 screws and some people just use no8 screws leaving the head proud

Walls now plastered and doors ready to go in
Do I need any special hinges or can I match what I have on other (much lighter) doors that are 76 x 51; I am going to fit 3 (rather than 2) as per manufacturer instructions, but they don’t specify what kind of hinges
I guess any hinge will be fine but I though I would ask anyway
