Hi,
The venerable Anderson shelter was built using a set of both curved and straight corrugated steel panels. Six curved panels were joined together by bolts to form the roof/top of the shelter, then three straight sheets were attached on either side of the shelter, and a further two more straight panels were finally attached at either end of the structure. One of these ends formed the entrance to the shelter. The whole structure was then buried anything up to 5ft to provide blast and shock protection from falling boombs and around 2 feet of soil was placed over the roof for protection from rubble and shrapnel.
They were often reinforced with baulks of timber to form a sub frame, and in some cases even bricks were placed over the roof (My grandmother in London retained her shelter and this was protected in that manner with a rock garden built over the top!) .
