General construction
Horseley Bridge pressed steel tanks are bolted mild steel sectional water storage containers. Plates are hot-pressed in our factory in the UK to BS1564:1975 Type 1. The panels are manufactured in 1m2 and 1.22m2 (4ft2) sizes with thicknesses ranging from 4-6mm depending on tank depth and use. Steel used in plates, stays, cleats, etc, conforms to BSEN10025:1993 S275JR (43A equivalent).
Plate dimensions are 1m or 4ft square. Half plates are available. Tank plates are bolted together using a Water Regulations Advisory Scheme (WRAS) approved sealant. For ease of access to bolts, tanks are supplied with external flanges unless customers specify otherwise.
To support pressures exerted by the tank’s contents, the sides of all tanks at the junction of four plates are supported by rolled steel angle stays attached to cleats of equal strength bolted to tank plates. The pattern of internal stays depends on tank size and varies between horizontal, vertical and diagonal.
