UNICOIL Galvanized Steel Brands

Mogalvin is the brand name of the hot-dipped galvanized steel produced by UNICOIL. The steel strip is coated with zinc using a continuous and controlled process. The tight metallurgical bond between the steel and coating takes place in a continuous galvanizing line supplied by Danieli, Italy. This process results in a material with the strength and formability of steel, but with the corrosion protection provided by zinc. The zinc coating protects the base metal from external corrosive elements in two main ways, by acting as (1) a physical barrier and (2) a sacrificial anode.

Mogalvin is available in various base metal grades and coating weights, and comes in special surface finishes tailored for specific applications. It is available as skin-passed and as-coated (regular) surfaces for the most demanding and critical surface applications, and can readily be painted when the appropriate pretreatment is performed.

Mogalvin is widely used in many applications in the construction, HVAC, appliance, automotive, and other industries.

Mogalvin is produced in conformance with international standards and specifications, such as ASTM A653/A653M, EN 10346, and JIS 3302.

Mogalvin is produced in commercial grades (CS), forming grades (LFQ/FS), or structural grades (SS 33, 37, 40, and 50).

To prevent staining during storage and in transit, the galvanized coils are lightly oiled or subjected to online chemical passivation treatment.

Hot-dip coatings are specified in a wide range of coating mass categories.

Product Packaging

 

Standard Packaging for Galvanized Steel Coils

Special Features of Standard Galvanized Steel Packaging

 
• Edges protected with cardboard edge protectors
• Plastic laminated VCI (vapor corrosion inhibitor) paper
• Steel inner ring
• Steel outer ring
• High-strength steel strapping
• Product label with all relevant information
 

Seaworthy Galvanized Steel Coils

 

Special features of seaworthy packaging:

 
• Additional plastic wrapping
• Additional cardboard wrapping
• Outer steel sheet jacket including the sides

Premium Packaging for Galvanized Steel Sheets

UNICOIL provides premium packaging for galvanized cut sheets. Bundles of these sheets are securely enveloped in VCI paper, above which a steel jacket wrapping the bundle is provided, and the bundle is tightly strapped with high-strength steel straps to strong wooden pallets to ensure protection from damage during handling and storage.

Premium Packaging for Slitted Coils

Galvanized steel coils are packed either vertically ( "eye to the sky," on pallets) or horizontally ("eye to the wall"), depending on the slit width and considering safety aspects for handling. For packing in the vertical position, each slitted coil is separated by wooden spacers for ease of handling, and each separated set of slitted coils is enveloped by VCI paper and placed on a strong wooden pallet. A steel outer ring is put around the set of slitted coils, and the entire set of slitted coils is tightly strapped to strong wooden pallets to ensure protection from damage during handling and storage. The horizontal packing is similar to that of galvanized steel coils.


Storage and Handling Advices For Customers

 

UNICOIL products are manufactured and packaged according to the highest international quality standards practiced in the metal coating industry. It is essential to prevent mechanical damage, distortion of coils, and moisture penetration in order to maintain the quality. The following best storage practices should be adopted:
