Header and Header Trench Construction - Steel Headers
Steel headers have been used for years in ice rinks but fell out of favour due to the tendency to rust on the outside and foul on the inside at the nipples. If the brine is rigorously monitored it will greatly reduce the problems associated with rusting. Steel headers can be used in an open header trench or a buried in the cement if protected from rusting. Due to their strength there is very little chance of breaking or damaging a steel header. They can be provided in straight sections or in curved sections forming the perimeter of the rink to eliminate frosting in the viewing area. As with PVC headers all polyethylene pipes should be double clamped with high quality stainless steel clamps. The cost of Steel headers is quite a bit higher than PVC headers.
