Steel plate is not problem of getting hold of. The new extension is a sip pre fabricated. Company putting it up Would you need plate as thick as mentioned 4x2 wall plate I'm not doing roof it's a sip building

4x2 wall plate I'm not doing roof it's a sip building

I reckon I can get 12mm steel plate between top of wall, and bottom of wall plate

Thanks I was probably over thinking it. And it was staring me in the face. How thick would steel plate need to be, only taking mono pitch roof

Existing external door frame which is having new roof over, will it require a lintel. Cannot be concrete, would make door height to low, as wall plate runs over just above door opening what are the options
