Unitrunk - Cable Management Systems - Technical Issues & Standards

Certificated Training - Galvanised - Stainless Steel - Electro-Zinc - CPD Presentations

Selecting the Correct Material

Cable management systems are predominantly supplied in four finishes:

  • Pre-Galvanised (BS EN 10346:2009)
  • Hot Dipped Galvanised (ISO 1461)
  • Stainless Steel (BS EN 10082-2:2005)
  • Electro-Zinc for cable baskets (ISO 4520:1981)

The important factor is to know when and where to specify which material.

Pre-Galvanised (BS EN 10346:2009)

Mild steel material pre-coated at the steel mill. Good resistance to rust in a dry indoor environment.

Not recommended for use in humid or outdoor installations.

Hot Dipped Galvanised (BS EN 1461)

Generally, and commonly referred to as “galv after” or “post-galv”, this is a mild steel material which is galvanised after the product has been manufactured. This process achieves a thicker coating of zinc which increases the products resistance to corrosion.

Products made of this material are suitable for outdoor installations.

Stainless Steel

Used extensively in the process industry and where product is required in harsh environments, 2 grades are commonly specified:

  • 304L: Specified for the pharmaceutical and food & beverage industry - this is a tough corrosion-resistant grade
  • 316L: Specified for coastal environments or areas with a high saline content - commonly referred to as “Marine Grade”

Stainless Steel is the only product that will prevent the formation of Zinc Whiskers.

Electro-Zinc (ISO 4520:1981)

Used extensively in the manufacturing process for cable basket. The steel wires are cut and welded together to form the cable basket which is then passed through a zinc bath. An electrolytic process applies the zinc to the steel to provide its coating. Suitable for use in dry indoor environments.

Not recommended for use in humid or outdoor installations.
