Zinc is incorporated between the bare steel substrates (both side) and the outer coating for corrosion resistance. Galvanization weight is confirming to BS EN 10147 with an average weight of 275 gm/m2 (20 microns). The combination of zinc and external coating adopted provides exceptional level of products performance and resistance to corrosion. Cuts and exposed edges are protected by electrolytic action as Zinc "drags over" covering sheared and punched area.
Aluminum Alloys are pre-treated by hot Sulphuric acid alternating Anodizing, Giving an excellent protection cover of Aluminum oxide. Natural oxidation can protect all cuts and exposed area.
It is a specially formulated flexible light gray backing cover with nominal thickness of 5 microns. The reverse side of the profile is normally coated with primer to provide adequate protection in dry internal environments.
Polyester is a 25 microns coating combining economy with excellent flexibility and temperature stability. Under normal environment condition, polyester coating is a durable protection cover. With appropriates attention sheet lifetime may increase considerably.
Polyvinylidene Fluoride is 27 microns thick coating. It is suitable for worldwide roofing and cladding applications. PVF2 is an inert fluorine modified system based on Kyner 500 resin. The coating is resistance to solvent attack and has continuous heat resistance (1200C). Color retention is improved in all climatic conditions. PVF2 has excellence life expectancy on the weather side subjected to appropriate maintenance.
Plastisol is a 200 microns (0.2mm) thick polyvinyl chloride coating (PVC). This coating exhibits an embossed leather grain finish. It is tough; withstand rough treatment in the workshop, during transit, and on site. It is scratch resistance, has good color stability. Plastisol is suitable for cold stores due to its excellent resistance to corrosion, temperature, and cleaning process.
Other finishes, such as ARS (Abrasive Resistance Surface) are also available. This type is used for cladding, guttering and general engineering purposes. It has good stain and dirt resistance, excellent mark resistance and color retention properties.
MEI can provide wide range of color with reasonable period of time. A stock of "fast moving" color is usually available. Color samples presented blow are for illustration only. These colors are not actual but are approximations and will vary according to you monitor\'s settings.
