I have a single story extension with lean to roof and with a 3.6m opening for bifolding doors and plan on fitting 2 RSJ's across this span, 1 on each cavity wall. As I've never done this before can I check the installation procedure for this.
- RSJ's will be about 4m in length, going to get them pre drilled to fit some wood on the underside, making it easier to attach/fit door frame, and wall plate on top.
- BC have stated RSJ's need to be bolted together, is its holes at 450 centres, then as these are I beams, nog out the gap and bolt together, or are there special brackets?
- Sit both RSJ's on 2/3 courses of engineering bricks, no specific fixing required, just brick round / bed in ?
- Want to lay row of bricks within lintel, anything to know, or just lay 'em
- BC havent asked for SE report, so I'm just going by the steel supplier's knowledge, sound ok?
thanks
