Specification

Product Description

This product can be supplied at standard lengths as listed or we can cut to your desired length at a minimum charge, just fill in the Custom Cut section. If you require more than 1 cut size, please reach out as we can optimise cuts. We aim to produce your custom cut to the exact length, however there is a production tolerance of +/- 2.0mm. All are square cut unless otherwise advised.

The most widely used stainless steel is the 304, also known as 18/8 for its composition of 18% chromium and 8% nickel. 304 may be referred to as A2 stainless. The second most common stainless steel is the 316 grade, also called marine grade stainless, used primarily for its increased resistance to corrosion.

Depending on the requirements of the application, the final finish can be anywhere between 120 and 320 grit. Higher grit numbers produce finer polishing lines and more reflective finishes. This general-purpose finish is widely used for restaurant, kitchen equipment, food processing and dairy equipment.
