Steel wire ropes are produced and classified following global industrial standards, which help international buyers quickly select the right type for their project, ensure safety and meet import inspection requirements.
Wire ropes can be classified in several mainstream ways according to international norms.
First, classified by structure type. Common types include 6×19, 6×37, 7×7, 7×19 and other conventional constructions. Different structures balance flexibility, wear resistance and breaking strength, suitable for cranes, elevators, marine use and general rigging.
Second, classified by surface treatment. This includes bright ungalvanized wire rope, electro-galvanized wire rope, hot-dip galvanized wire rope, and stainless steel wire rope. Each grade offers different corrosion resistance for inland, coastal and offshore harsh environments.
Third, classified by core type. Fiber Core (FC) and Steel Core (SC) are the two main categories. Fiber core provides good flexibility, while steel core offers higher load capacity, compression resistance and longer service life for heavy-duty working conditions.
Fourth, classified by lay type. Regular lay and Lang lay, right lay and left lay are standard classifications, designed to adapt to different equipment operation habits and prevent twisting or kinking.
Following international classification standards makes it easier to compare technical parameters, check certification documents, and place accurate bulk orders. It also helps end users achieve safer operation, lower maintenance costs and better overall economic benefits.
