Hi all.
I'm converting a serving hatch opening into a doorway (820 wide) & I'm after a bit of lintel advice.
The wall I'm making the doorway in is a structrual wall, it has the upstairs floor joists resting on it & is 100mm brick. The wall doesn't carry on upstairs, it only holds the weight of the upstairs floor.
The lintel above the existing serving hatch is 7" deep which seems a bit ott, but was probably used because that's what the builders had.
Wickes sell 100mm wide x 70mm deep concrete lintels, which would be convient for me to get, or I can get a 140mm deep lintel from a merchants.
Is 70mm deep likely to be strong enough for the new doorway, & what end bearing should I give? Would 100mm be ok for an end bearing.
Thankyou.
