GALVANIZED PLAIN STEEL SHEET/COILS

– Advantages:

+ Vina One Galvanized steel sheet is produced under a modern production system with innovative hot-dip galvanizing technology of NOF.

+ Vina One Galvanized steel sheet is high impact resistance to corrosion in different environments, it also meets the standards of ASTM (USA), JIS (Japan), BS (UK), AS (Australia) and TCVN (Vietnam).

– Applications:

+ Office Furnitures: shelves, signboards, billboards, etc.

+ House applications: push door, rolling door, wardrobe, waterspout, etc.

Vina One not only manufactures the products as our standard commercial specifications, but also make to customer’s orders.
