Hello, I am ready to order steel for my building project. Its an open plan extension.
I have had the steels specified by an engineer but just want be clear of what to order.
The opening is in a 1930s semi detached house (solid 9 inch wall) and is approx 7.5 metres with 2 point loads.
The engineer has given me 2 options for the main beam:
1) use 254 x 254 x 167kg
(This option is not practical as due to the overall weight and would need crane to lift off flat bed and into position)
2) use 2no x 203 x 203 x 113kg - I am going to go for this option.
The steel will sit on goalpost support columns at each end
203 x 203 x 46 UC on
250 x250 x 8mm Base plate
With 250 x 250 x 20mm head and sole plates
My question is - Do I need 2 goalposts at each end or just 1 with a bigger head plate to match the total width of the 2 steels bolted together (16 inch)?
Thanks
