Model Number: CHSWR20130529
Key Specifications/Special Features:
Features:These wires are coated before the final drawingThe result is a zinc coated wire with a very smoothsurfaceThere 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 propertiesAccording to finishing is designated by the letter B or ArespectivelyThe grade of the wire is the minimum breaking strength the mostcommon grades used are: 1370 N/mm, 1770 N/mm, 1960N/mm, 2160 N/mmOther 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/mm, grade EIPS is close to1960 N/mm
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)
