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 product performance and resistance to corrosion.
Cuts and exposed edges are protected by electrolytic action as Zinc “drags over” covering sheared and punched area.
Aluminium Alloys are pre-treated by hot sulphuric acid alternation current Anodizing, Giving an excellent protection cover of Aluminium oxide.
Natural oxidization can protect all cuts and exposed area.
MEI can provide a wide range of colours with reasonable period of time. A stock of “fast moving” colour is usually available. Colour samples presented below are for illustration only. Actual colour may vary depending on substrata supplier and batch.
It is a specially formulated flexible light Grey backing cover with nominal thickness of 5 micron. The reverse side of proﬁ le is normally coated with primer to provide adequate protection in dry internal environments.
Polyester is a 25 microns coating combining economy with excellent ﬂ exibility and temperature stability. Under normal environmental condition, Polyester coating is durable protection cover. With appropriate attention sheet lifetime may increase considerably.
Other ﬁ nishes, 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.
Polyvinylidene Fluoride is 27 micron thick coating. It is suitable for worldwide rooﬁ ng and cladding applications, PVF2 is an inert fluorine modified system based on Kynar 500 resin. The coating is resistance to solved attack and has continuous heat resistance ( 120°C).
Color retention is improved in all climatic conditions. PVF2 has excellent life expectancy on the weather side subjected to appropriate maintenance.
Plastisol is 100-200 microns (0.1mm-0.2mm) thick polyvinyl chloride coating (PVC) this coating exhibited an embossed leather grain ﬁ nish. It is tough; withstand rough treatment in workshop, during transit, and on site. Plastisol is suitable for cold stores due to its excellent resistance to corrosion temperature and cleaning process.
HIGHLY REFLECTIVE ROOF COATING
Highly reflective roofs can reduce the indoor temperature of buildings by 10 to 12 degrees Celsius, which lowers their cooling needs and thus results in cooling energy savings of approximately 10 to 20 percent on the ﬂ oor under the roof. The thickness of the Insulation fill material (E.g. – Rockwool) can be reduced without compromising the thermal resistance of whole system
» Reduce energy bills by decreasing air conditioning needs,
» Improve indoor thermal comfort for spaces that are not air conditioned,
» Decrease roof operating temperature, which may extend roof service life
Reduce local air temperatures, which improves air quality and slows smog formation; Reduce power plant emissions, including carbon dioxide, sulfur dioxide, nitrous oxides, and mercury, by reducing cooling energy use in buildings; and Reduce heat trapped in the atmosphere by reﬂ ecting more sunlight back into space, which can slow climate change
