NSRS give the wide range of products in rolling shutter in a very cost-effective prices. Galvanized Rolling shutters mainly made up of steel slabs interlocked to each other. This kind of Rolling Shutters are very versatile and come with several options, so they can be designed to suit our customer’s requirements. We can offer different thickness of steel – depending on the size of the door; either a galvanized finish or powder coated finish. Our standard door curtain is manufactured from 0.6mm galvanized steel lath which is suitable for the majority of commercial applications, as well as offering a high security. However, for very large doors, or doors fitted in very windy areas or any unusual sites, we can offer a heavier upto 1.4mm steel lath for the curtain and wider guide tracks or wind lock guides. The galvanized steel finish does not generally rust but does dull over time. Powder coating is available to any standard RAL as an alternative finish but does increase the price of the doors substantially. An alternative would be to paint the doors but a decent primer would be needed.
