Two layers of wires are formed around a centre wire, with each layer having an
equal number of wires. The large outer wires, specifically designed for increased
abrasion resistance, are resting in the valleys between the small inner wires.

SEALE CONTRUCTION
Two layers of wires are formed around a centre wire, with each layer having an
equal number of wires. The large outer wires, specifically designed for increased
abrasion resistance, are resting in the valleys between the small inner wires.
FILLER CONSTRUCTION
Small filler wires, equal in number to the main inner wires, are used to prevent the
outer wires from being pressed into the valleys between the inner wires.
Due to good abrasion and fatigue resistance characteristics, this construction has
become most popular for general purpose wire ropes under the 6 x 19 classification.
WARRINGTON CONSTRUCTION
The outer layer of wires are composed of alternating large and small wires, formed
around a layer of uniform-sized wires. The smaller outer wires rest on the crowns, the
larger ones in the valleys of the inner wires.
WARRINGTON SEALE CONSTRUCTION
A combination of Seale and Warrington Constructions, it features large outer wires
with the main layer being composed of alternating large and small wires.
