Spiral pipe combines the economies of light gauge metal with a spiral lock seam construction that assures maximum strength and rigidity. As a result of its superior structural strength, spiral requires fewer joints and hangers. Four ply's of metal form a continuous interlocked reinforcing rib on the outside which allows making different lengths of pipe in various diameters from strip stock of specified gauge.

Standard Elbows and Angles are fabricated from 24 gauge galvanized material.  Other diameters, throats radiuses and gauges are available.

52" and larger in diameter 90-degree elbows are fabricated using two 45 degree angles unless otherwise specified.
