Structural Pipes
We are manufacturers and exporter of Structural Pipes. These pipe is available in CW, ERW & DSAW, in all sizes, weights, and classes of material. Rejected pipe which cannot be classified as a prime product because of some physical or chemical defect is sold by the mills to steel pipe distributors, distributors of steel products, fabricators, and consumers. Although reject pipe carries no warranty whatsoever, it can have application for structural purpose.

Few of the typical examples where reject pipe has been used as structural steel tubing and pipes are handrails, columns, posts, piling, sand-wash, casing, culverts, fence, caissons, sign poles, bumpers, bracing, parking meter posts, towers, supports, rollers, etc. Structural steel pipes and tubing are normally priced substantially under prime pipe and can affect large savings in the right application.
