The roof supports for Mains Water supply tanks are manufactured as spiral welded tubing in 316 stainless steel material and are always designed by specialised client’s experienced engineers prior to our manufacture. These pipes are always manufactured to exact length avoiding costly wastage of material and can be manufactured up to 1500mm in diameter and 5mm in thickness while complying with AS4041. They are usually supplied with a base and top plate for ease of site assembly and are always acid pickled and passivated prior to site transportation.
