Product Description
Product Description
- These wires are coated before the final drawing
- The result is a zinc coated wire with a very smoothsurface
- There are two types of finishing: quality B is the most common,it has a thinner zinc coating but the same mechanical properties asan un-coated wire quality A has thicker coating but lowermechanical properties
- According to finishing is designated by the letter B or Arespectively
- The grade of the wire is the minimum breaking strength the mostcommon grades used are: 1370 N/mm², 1770 N/mm², 1960N/mm², 2160 N/mm²
- Other grades are used for some special applications
- The North American market uses a different scale of gradesaccording to U.S. federal specification RR-W-410: traction steelmild plow steel (MPS) plow steel (PS) improved plow steel (IPS)extra improved plow steel (EIPS) extra improved plow steel(EEIPS)
- The most common grade for general purpose wire ropes is IPSwhich is quite close to 1770 N/mm², grade EIPS is close to1960 N/mm²
- The actual strength of the steel in these grades varies withthe wire diameter
- The core: fiber core (F.C.), usually polypropylene (P.C.),sometimes hemp (H.C.) and sisal
- Independent wire rope core (IWRC)
- Wire strand core (WSC)
- IWRC and WSC are sometimes referred to as steel wire core orsteel center
- Construction: expressed in numbers of strands x number of wiresfor example: 6 x 25 indicates that the wire rope consists of 6strands, which in turn have 25 individual wires
- Lay: right regular lay (RRL), right lang lay (RLL), leftregular lay (LRL), left lang lay (LLL)
