Technical Datasheet - Expansion Joints Aluminium Covers, Screw Fixing & Self Adhesive - GC28 Product Description Genesis GC2801, GC2811 and GC2815 are Aluminium cover strips designed for concealing joints in walls ceilings and floors. The suitability of aluminium must be determined if Chemical or mechanical stresses are anticipated. Dimensions and Colour Available in 60mm, 80mm and 100mm widths. The 60mm and 80mm widths GC2801 and GC2811 are available in lengths of 3.4m. The 100mm width GC2815 is 3.0m long. All are anodised in a Matt Silver Finish. Technical Details Profiles supplied in anodised finishes - All natural Aluminium (Mill Finish) has a oxide film of approx 0.2 microns, when Mechanically & Chemically polished the anodising process increases this to 5 microns, up-to 20 for the Matt finish. Genesis GC2801, GC2811 and GC2815 profiles do not require any special maintenance. Oxidation films on Aluminium may be removed with a common polishing agent; however, they do reoccur. Damaged anodised finishes may only be repaired by recoating. Aluminium must be tested to verify its suitability if chemical stresses are anticipated. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and time of exposure) may result in corrosion (aluminium hydroxide formation). Therefore, it is Aluminium AA 6063 T6 / UNS A96063 anodised to DIN 17611 Si% 0.2-0.6 Fe% 0.35 Cu% 0.1 Mn% 0.1 Mg% 0.45-0.9 Zn% 0.1 Ti% 0.1 Cr% 0.1 Al Balance important to remove adhesive or grout residue from visible surfaces. In addition, ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water. The anodised layer creates a finish that retains a uniform appearance during normal use. The surface, however, is susceptible to scratching and wear and may be damaged by tile adhesive, mortar, or grouting material. Therefore, setting materials must be removed immediately. Otherwise, the description regarding aluminium applies. P.V.C.
