Stainless Steel

Used for products to be installed in the harshest of environments

and in various process facilities. Unitrunk offers two grades of stainless steel material.

304

: Used extensively throughout the industry. This is a tough, corrosion resistant austenitic grade of stainless

steel which is popular in the food and pharmaceutical process industries. Unitrunk cable trunkings are as

standard supplied in this grade of material.

316

: Also referred to as Marine Grade. This austenitic grade of stainless steel through the addition of molybdenum

is used mainly for installations which are exposed to high saline content environments such as offshore facilities

and coastal environments. Our cable ladders, cable trays and support channels are supplied as standard in this

grade of material. These two grades of stainless steel are to BS EN 10088-2:2005.

Galvanised After

Products to this finish are manufactured from mild steel and

galvanised after manufacture in accordance with BS EN 1461. These products achieve a thicker

coating of zinc which enhances the products resistance to corrosion. Products to this finish are

suitable for outdoor installations.

Powder Coated (Multicoloured)

The painted finish is achieved by powder coating

the base steel. This process is achieved by electrostatically charging the base material and then applying a

free flowing, dry coloured powder to it. Heat is then applied to allow it to flow and form a “skin”. The powder

coated finish is very tough and durable providing relatively good corrosion protection. It can be applied to

any type of steel finish, including post-galvanised.

Galvanised After Manufacture Corten A Steel:

This material is used for

products to be installed in environments where high levels of humidity and/or where corrosive substances are

present. The high silicon content of Corten A substantially increases the zinc coating thickness which adheres

to the surface of the steel thereby extending the life cycle of the installation. The typical zinc coating thickness

achieved on 2.0mm mild steel, in accordance with BS EN 1461, is 55

(microns) whereas 2.0mm Corten A steel

can comfortably achieve a coating thickness of 140

, more than doubling the time to first maintenance.

Pre-Galvanised 750 + 900

Mild steel material to BS EN 10346:2009, pre-coated at the

steel manufacturers. Good resistance to rust in a dry, indoor environment. Not recommended for humid or

outdoor installations.
