Axis Textured Sheet (Ano-Sil Anodised Finish)

Introduction

Ceram Building Technology carried out tests on various aluminium panels to determine their resistance to surface marking.

Sample Description

The following 1000mm x 500mm sheet samples were tested:

  • Plain mill finish (reference sample)
  • GA AXS21

Test Method

Each sample, commencing with the plain mill finish, was horizontally attached to a rigid substrate.

A 120mm x 40mm piece of P40 grade emery paper was placed, abrasive side down, onto the sheet. Lead weights, totalling 2.16kg, were then placed onto the emery paper. A cable, attached at one end to weights and passing over a pulley, was then attached to the emery paper and allowed to pull the emery paper and lead weights along the surface of the sample sheet.

This procedure was carried out once on the plain mill finish and the damage to the surface assessed visually, at an angle of approximately 45 degrees and a distance of approximately 1 metre.

Test Results

The full results for the tests are given in Table 1.

From the results obtained it is clear that the surface texture of the sample or profile of the sample is the major controlling factor to the visual assessment of the damage.
