01Overview
About GI Solid Rolling Shutter
A GI shutter is a mild steel shutter with the corrosion problem addressed at the material rather than at the paint. The zinc coating is on the steel before the slat is formed, so the protection is not something that has to be maintained on site to keep working.
Operating method
03Variants
Available configurations
The same product, built for a different job. Where a specification depends on opening dimensions, selected profile, operating duty or site conditions, the final configuration is confirmed during technical assessment.
Standard duty — 0.8–1.0 mm class
Interlocking galvanized curtain in the 0.8 to 1.0 mm class, manual, gear or motorised, for shops, commercial buildings, godowns and outdoor openings.
Heavy duty — 1.2 mm
Heavy interlocking GI curtain at 1.2 mm with a reinforced guide, gear operated or motorised, for warehouses, godowns and commercial or industrial buildings.

FAQ
Questions we are actually asked
- How much longer does a GI shutter last than a painted MS one?
- We do not publish a figure, because it depends on the environment, the coating specification and how the shutter is maintained. What is fair to say is that the corrosion protection is in the steel rather than in a surface finish, which is why it is the better choice for an exposed opening.
- Can a GI shutter be powder coated?
- Yes. The galvanized base does the corrosion work and the powder coat gives the colour, which is the usual specification where the shutter is on a visible elevation.
- Is GI suitable for a coastal site?
- It is better than mild steel, but for a genuinely coastal or chemically aggressive installation we would point you at Galvalume or stainless steel rather than claim GI will be sufficient.
- What sizes is the GI Solid Rolling Shutter available in?
- It is made to the opening rather than supplied in fixed sizes. Send us the clear width and height along with the headroom and side room available, and we will confirm what the configuration supports.
- Can it be motorised, and can an existing shutter be motorised?
- Yes to both, where the curtain and barrel suit it. Motor selection follows curtain weight, opening size, barrel diameter and how often the shutter runs, so it is calculated for the opening rather than taken from a product line.
- What happens during a power failure?
- Every powered shutter is supplied with a manual override, by hand chain, crank or release depending on the configuration. It is part of the specification rather than an accessory.
- What do you need from us to quote?
- Clear opening width and height, the headroom and side room, roughly how many times a day it will be used, whether it is internal or external, and the finish you want. That is usually enough for a configuration and a price.
