Steel is an alloy created by adding carbon to iron, and is used for its strength, which is given by its alloy elements.
Zinc plating acts as a barrier which prevents corrosion and rusting. Cable pullers are made from zinc plated steel because it is durable, so they are able to withstand wear.
Drop forged steel
Some cable pullers have parts that are made of ‘drop forged steel’. Drop forging is the process where a hammer is raised then ‘dropped’ onto the workpiece to deform it into the required shape/form, either by hand or machine.
Drop forged steel provides cable pullers with high strength.
