Welcome to the page dedicated to the production stages of REMER steel wire ropes.
Discover the processes that make our products unique, from wire drawing to plastic coating, ensuring quality, strength and reliability in every application. Each stage is designed to provide outstanding performance even in extreme operating conditions.
The wire is the basic component of the steel rope and is obtained by drawing from wire rod. Through several operations, wire rod of a given diameter is transformed, by successive reductions, into wire with predetermined dimensional and mechanical characteristics.
Rope wires are protected by appropriate lubrication. However, ropes for marine use or intended to work in aggressive environments or exposed to weather conditions have zinc-coated wires.
Galvanizing is carried out by immersion in a bath of molten zinc. The wires may be galvanized after the final drawing operation (final galvanizing) or galvanized and subsequently drawn.
The amount of coating is expressed as the mass of zinc per unit of wire surface in g/m², according to EN 10264-2. REMER supplies ropes with:
This is the process for producing the strand, i.e., a group of wires arranged helically around a central core made of metal wire or natural or synthetic textile fibre.
This is the process by which the rope is produced: several strands are wound around a textile or metal core through the closing operation.
Before this operation, the strands undergo a “PRE-FORMING” process to give them the helical shape they will have in the rope’s final structure.
Pre-forming provides several advantages: when the rope is cut the strands do not unwind, eliminating the need for bindings or welding; rope fatigue resistance increases; in case of wire breakage, wires maintain their position; handling and splicing operations become easier.
Compacted strand ropes are particular types of ropes produced using high fill-factor strands. Compacting is achieved by deforming the wires during stranding so that most of the voids between wires are eliminated.
The result gives the strand a greater cross-section at the same diameter and a uniformly smooth outer surface.
On the other hand, wire deformation significantly increases contact surface areas, reducing pressures generated between wires during operation.
The combined effects produced by compacting allow the creation of ropes with higher breaking loads, greater fatigue resistance, and better resistance to abrasion and pressures caused by sheaves, drums, etc.
The REMER product range also includes ropes with internal plastic coating, which means a polyurethane layer between internal and external strands. This reduces rope wear and seals the inside from oxidation and dirt.
