andadam Posted August 31 Share Posted August 31 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)?

Mr Punter Posted September 1 Share Posted September 1 This is one for your engineer. They should give you full spec, calcs and drawings for the connections. One column either end sounds simpler. Link to comment Share on other sites More sharing options...
