SPIRAL Elbows

Superior’s spiral elbows are formed from a continuous strip of galvanized sheet steel, which utilizes the same 4-ply spiral lock seam in a rolling process.


This eliminates the need for welding, sealants, broaching, and VOC paint touchup’s. Superior’s single form process ensures consistency, quality, and tolerances that are strictly controlled elbow to elbow.


Since the elbows are formed without welding, this allows us to avoid increasing metal gauges in the prevention of burn-through. A 26 gauge spiral elbow has 22% less metal than a 24gauge elbow, and 36% less metal than a 22gauge elbow.

 

This means that the production process of these spiral elbows generate a substantial reduction in raw material costs and in addition, have a less negative impact on the environment.
