Aluminum Coil for Rolling Shutters: Alloy and Thermal Coating Options.
Rolling shutters are a more established, everyday building product across Europe than they are in North America, where they show up more as a specialty item. That difference in familiarity is worth knowing before getting into the coil specification itself.
Key takeaways
- Rolling shutters are a more established building product in Europe than in North America, which shapes who is typically asking about this specification.
- Slat forming is a tight, repetitive roll-forming operation, so alloy and temper selection matters as much here as for roofing or gutters.
- Orbit offers a named thermal-management coating option for rolling shutter and facade applications; specific thermal performance data is available on request.
- Coating choice affects how tightly a slat profile can form, the same general flexibility tradeoff that applies to any tightly formed coil product.
- Orbit's 1xxx, 3xxx and 5xxx alloy range and full coating program cover shutter slat coil.
What makes slat forming a demanding roll-forming operation?
The slat profile is tight and repetitive, run continuously through a series of rollers to produce a shape that has to interlock consistently along the full length of every slat in a shutter. Any inconsistency in the coil shows up as a functional problem, not just a cosmetic one, since the slats need to roll and unroll cleanly.
That makes alloy and temper selection matter as much here as it does for roofing or gutter profiles, where the coil also goes through continuous roll forming rather than a single stamped or cut operation.
Which alloy suits shutter slat forming?
Within Orbit's 1xxx, 3xxx and 5xxx range, 3xxx is a common choice for shutter slats, offering the formability a tight, repetitive profile needs alongside general corrosion resistance suited to exterior use. 5xxx is the upgrade where a project needs more strength or sits in a more demanding environment.
See what the 1xxx, 3xxx and 5xxx numbers actually mean and our alloy and temper guide for coil coating for how temper interacts with a tight forming operation like a shutter slat profile.
Does coating choice affect how tightly a slat can form?
Yes, the same general tradeoff that applies to any tightly formed coil product. PVDF-class coatings are generally less flexible than polyester-family systems, which is worth checking against a slat profile's bend radius before the coating is finalized, since a coating that performs fine on a flat panel can craze at a tight, repeated fold.
See choosing a coating system for exterior aluminum coil for the general durability and flexibility differences between Orbit's exterior coating systems.
Does Orbit offer a thermal-management coating option for shutters?
Yes, a named coating product positioned for rolling shutters, facade and roofing applications where thermal management is part of the brief. Specific performance figures for that system are available on request against your specification rather than published as a general claim here.
Where thermal performance is a genuine driver for a shutter program, it is worth raising early in the enquiry alongside the standard alloy, gauge and coating specifics, so the right system can be confirmed against your actual requirement rather than assumed, particularly since thermal-management coating options are not interchangeable with standard exterior systems on a like-for-like basis.
What role does finish play beyond color?
The same range that applies across Orbit's coil program: solid, metallic, woodgrain, brushed, matte, gloss and textured, in RAL or custom colors. For shutters specifically, finish choice tends to follow the building's existing facade or window trim more closely than it does for a standalone application like signage, since the shutter sits directly against those surfaces when open.
On markets where rolling shutters are a standard fitting rather than a specialty item, this alignment matters at the scale of a building product line, not just a single installation, since a shutter manufacturer is typically matching a defined set of facade colors across many projects rather than choosing a finish once.
What should go in a shutter slat coil enquiry?
The slat profile and its tightest bend radius, whether thermal management is a requirement, and the environment, alongside standard alloy, gauge and coating specifics.
- Slat profile and its tightest bend radius
- Whether thermal-management coating is a requirement
- Alloy preference, or the environment if still open
- Coating system and finish, matched to the building's facade
- Color reference, RAL or custom
- Quantity and destination
Minimum order quantity is 6.5 MT. Coil ships from Aqaba, with transit to Europe of 5 to 13 days port to port and to the USA of around 25 days. Orbit supplies coil for rolling shutter applications across this range. The National Coil Coating Association (NCCA) is the trade association representing coil coating businesses in North America.
Common questions
What alloy does Orbit recommend for rolling shutter slats?
3xxx is a common choice for the formability a tight, repetitive slat profile needs, with 5xxx as the upgrade for higher strength or more demanding environments. Both are within Orbit's 1xxx, 3xxx, 5xxx rolling program.
Does Orbit offer a thermal-insulation coating for shutters?
Yes, a named coating option positioned for rolling shutter, facade and roofing applications. Specific thermal performance data is available on request against your specification.
Can PVDF be used on a rolling shutter slat?
It depends on the bend radius the slat profile requires, since PVDF-class coatings are generally less flexible than polyester-family systems. Send your profile and we will confirm the coating options that fit it.
Is rolling shutter coil sold in the same gauge range as roofing coil?
Yes, Orbit rolls coil from 0.20 to 2.00 mm thick and up to 1650 mm wide across applications, and we confirm gauge against your specific slat profile.
What is the minimum order quantity for shutter slat coil?
6.5 MT. Coil ships from Aqaba, with transit to Europe of 5 to 13 days port to port and to the USA of around 25 days.
