Spiralweld pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiralweld pipe is as strong as API pipe. The strength and flexible manufacturing of spiralweld pipe make it the product of choice for a variety of applications.

Spiralweld pipe is ideal for bearing piles since it can be produced in a wide variety of sizes, grades, and lengths. It is also easy to splice and can be driven open or closed-ended. Closed-ended pipe can be filled with concrete. The American Society of Civil Engineers (ASCE) recommends a lower safety factor for concrete-filled, closed-ended pipe than any other type of driven or drilled foundation, primarily due to the predictability of a quality installed product. Spiralweld pipe is also used for king piles for pipe-z sheet pile walls, casing for drilled shafts, bracing for cofferdams and sign poles.
