If your nature of business requires you to allow air to flow through the entrance of your premises, you may consider these types of roller shutters which would meet your requirement :
Aluminium Flat Slats with Ventilation Holes Roller Shutters
Aluminium Flat Slats with Ventilation Holes Roller Shutters is a popular type of roller shutters where ventilation holes can be punched according to your preference.
For instance, if you do not need a set of roller shutters with too many ventilation holes, you may request to have the holes punched only at the top few roller shutter slats or the top few rows.
The more holes there are on the panel, the more air can pass through.
Aluminium Roller Grilles (with Brick Bond or In-Line Design)
Aluminium Roller Grilles which are made up of aluminium tubes secured together are ideal for those that require maximum ventilation within their premises as the gaps between these aluminium tubes are quite large.
Types of roller grilles that you may choose from are either Aluminium Roller Grilles with Brick Bond or Aluminium Roller Grilles with In-Line Design.
In terms of ventilation, both types are similar and allow almost the same amount of air to flow through.
Aluminium Roller Grilles with Acrylic Strips
Another type of shutters which allow air to flow through is the Aluminium Roller Grilles with Acrylic Strips.
This type is rather similar to Aluminium Roller Grilles except that acrylic strips are inserted.
It allows slightly less air to flow through than the ones without the acrylic strips inserted but comes with an additional layer of protection.
Perforated Steel Roller Shutters
The final type of roller shutters is Perforated Steel Roller Shutters which are manufactured from steel instead of aluminium.
The perforations or holes on the shutter panels are smaller than ventilation holes that are punched on Aluminium Roller Shutter panels although the number of holes are much greater.
Perforated Steel Roller Shutters allow a good amount of air to flow through your premises and are suitable for those that require heavy duty roller shutters which are slightly heavier than aluminium roller shutters due to the nature of the materials used.
All these types of roller shutters allow air to flow through. As to which of the above 4 types is better, it depends on your nature of business and its requirements.
The above types of roller shutters can also be powder coated with your preferred colour upon request except for Aluminium Roller Grilles which come in natural anodised finish.
