bonding mushroom unit

[wolfiehogan]

hi, am carrying out work in a mushroom unit/house and am not sure how i bond the steel structure off the shed.i will try and explain the structure. there is 3 rows of steel poles running the length of the shed and cross beam connecting these the hole length of the shed. all these beams are connected together with steel clips. my problem is do i need to bond all off these beams or how to i go about bonding it. hope some body can help

A variety of suppliers do the earth clamps (beam clamps) that will clamp onto the edge of an I beam including they that shall not be named, if there is an edge on your beam they should fit. Alternativly would an ordinary earth fitting for a pipe fit the tubes?

Earth the peripheral accessible steel work at ground level with clamps. There should be adequate continuity to the roof beams and central uprights in the construction. The central uprights can be tested at ground level to confirm continuity. To be honest there should be no need to bond them.
