can anyboby tell me what size steel girder i would need to
make a 7' opening in an 11' wall, thats leaving a 2' peir each side of the opening.
also how many blue bricks for the pads and how to arrange the blues.
would i be right in saying the girder would need to be double boarded
for fire regs.

any info would be great..

Without looking at your project it very difficult to know on this forum as for: is it a low bearing walls,single or double walls,bungalow,house,flat and what weight you're supporting above.The building regulation require that you must have as least 150mm each side of the opening.To help you this website can calulate the size you'll need online. www.lintels.co.uk
