With it's origin over 60 years ago as a dry silo cover, the knuckle roof's application has greatly expanded to a variety of liquid and dry storage needs. For an economical cover for small diameter silos and tanks in an area of higher environmental loads, this type cover is hard to beat.
For small diameters where static loads are minimal, a knuckle roof is the most economical cover. Easy of installation adds to the cost benefits of this type cover.
Knuckle roofs are limited to 31 ft (9.5m) in diameter which makes them ideal for silo covers. Most sizes are predesigned and have reduced manufacturing times.
Higher Environmental Loads
Unlike flat steel roofs, knuckle roofs have a high slope which minimizes the internal structural support. This makes knuckle roofs an ideal solution to silos and small diameter tanks in high snow load areas.
Having been integrated onto silos and tanks for over 60 years, there is a tremendous amount of field data validating the knuckle roof designs. Knuckle roofs have a proven life expectancy even in extremely demanding applications such as leachate tanks and digesters.
Variety of Materials
Knuckle roofs are predominantly manufactured in Vitrium glass-fused-to-steel, they can also be manufactured in stainless steel and other materials. CST's engineers can match the customer's needs with the material and design to meet the application requirements.
Knuckle roofs are common for the following applications:
Knuckle roofs are standard on all Harvestore silos. It is a tested and field proven roof that provides years of life and seals the Harvestore system effectively.
Knuckle roofs are also used very effectively for all types of liquids from water to industrial chemicals. It provides a reliable and safe cover for your application.
