CME provides all kind of coating for our products, following are the main divisions
Following are the features of our Galvanizing plant:-
The company has set up well-documented acceptance standards and testing criteria for the galvanized products, which are based on international standards For Hot dip galvanized coatings on fabricated Iron & steel articles (BS EN ISO: 1461:2009, ASTM A 123/A 123M-09, ASTM A 153/A 153M-09, ASTM A 53/A 53M Type E or S, grade B and ASTM A143M) for Galvanizing. The acceptance criteria are strictly followed and any material, which deviates from the same, is rejected and reprocessed.
It has been our continuous endeavor to improve our overall Quality Management System and our process system. CME has followed a policy of continual improvement both in process as well as products. This has resulted in improved quality and speedy delivery of all our products thereby resulting in better customer satisfaction and we are sure to extend the same to our Galvanizing process
CME operates from its own premises in the heart of the industrial area in Sharjah, UAE. We welcome enquiries for our full range of products and assure prompt and professional attention to all our customers’ needs and wants.

Zinc plating is the most common and economical type of plating. Zinc plating is a soft, protective by nature, decorative, ductile, and marginally solderable and also serves as an effective undercoat for paints. It is sacrificial coating, so that part does not corrode. Zinc plating is available in clear, yellow, black and olive green.
On the commercial scale, zinc electroplating is done by the following steps
It is very difficult to obtain a uniform thickness of coating, with electroplating technique. The thickness of the coating is very much dependent on the geometry of the object being plated, and it is preferentially on the external corners and protrusions of the metal body, hence not much of it is deposited on internal corners and recesses. Zinc electroplating process is used to make a clean, smooth and corrosion resistant surface. It also makes an excellent undercoat for powder coating or paint and can leave recesses on complex shaped components without sufficient zinc coating, in order to provide corrosion protection.
THE POWDER COATING PLANT PROCESS:-
Powder coating has today established itself as the most effective means of metal surface finishing. It has replaced liquid painting and various methods of electroplating due to the many advantages this process offers …Powder coating is a simple process requiring minimal skills and training. The articles to be coated are first cleaned of all foreign matter from the surface. Mild steel components need to go through a phosphate conversion coating. Aluminum components go through a chromate conversion coating. This, known as pretreatment, is employed for improved bonding of the powder coat to the material being coated to provide a longer life to the coat. The method employed usually is a dip in chemicals and water in various tanks. Occasionally, the process may be automated through a spray pretreatment process.
A batch powder coating system:-
The ‘pretreated’ articles are jigged and hung into the coating booth on a fixed or rotatable jig-holder. The manual coater coats the components from all sides. The articles are then moved out onto an oven trolley (or directly into the oven). The trolley, if used, is rolled into the oven when full. In the oven, at a temperature of 180-220oC, in 10-15 minutes, the powder melts, polymerizes fuses and cures into the final tough uniform and consistent powder coat that has high aesthetic value. At the end of the curing schedule, the trolley is rolled out of the oven and allowed to cool down. The articles are then removed out from the paint-shop.
A conveyorized powder coating system:-
The ‘pretreated’ articles are jigged and loaded onto the continuously moving overhead conveyor. As the conveyor moves the articles through the coating booth, they are coated on all sides by manual and/or automated spray guns. The conveyor then carries the articles into the tunnel oven (or in a semi-automated version, the articles are offloaded for off-line curing). In the oven, at a skin temperature of 180-220oC, in 10-15 minutes, the powder melts, polymerizes, fuses and cures into the tough uniform and consistent powder coat that has high aesthetic value. At the end of the curing schedule, the article moves out of the oven (or the trolley is rolled out of the oven) and allowed to cool down through a cool-off zone. The articles are then removed off the conveyor and taken out of the paint-shop.
The Powder Coating System
Complete powder coating systems come in two versions – a batch system and a conveyorized system. The primary difference is the mode of material movement from operation to operation. Powder coating itself may be by manually held spray guns or by automated guns fixed-mounted or reciprocator-mounted.
PRETREATMENT SYSTEM
consisting of tanks or tubs containing chemicals or water in which the articles are dipped to clean and prepare the surface for powder coating. The size of the tanks depends on the size and quantity of articles to be coated. The specific process depends on the metal make-up of the article.

POWDER SPRAY SYSTEM (also known as the powder coating machine)
is considered the heart of the powder paint shop. Normally an electrostatic powder spray system is used. This sprays electro statically charged powder into the spray booth where the articles to be coated are hung. Electrostatic forces provide a uniform and consistent coating quality. Major strides have been made in the design of these machines offering major benefits to the user.
POWDER COATING BOOTH WITH RECOVERY SYSTEM
in which the actual powder coating is carried out. The efficiency of recovery of over sprayed powder for reuse decides the economics of powder coating. The efficiency of overall retention of over sprayed powder decides the pollution-free worthiness of the system. There are two types of powder recovery booths – Filter Cartridge type and the Hyper Cyclone type.
CURING OVEN
in which the powder coated articles are placed for 10 to 15 minutes at the recommended temperature for the powder to melt, polymerize, fuse and cure into the final finish of high aesthetic appeal with strong mechanical and chemical properties.
