Roll Shutter Slat Types

40mm Extruded Aluminum

F.B.C. Approved & Miami Dade Approved 

The 40mm is a traditional extruded aluminum slat. Its small profile makes this a great choice for openings that may have a limited amount of space above the opening for the shutter housing. Shutters up to 84” in height require only a 7” housing. With a design pressure of 40 p.s.f.  the 40mm can span 54” between the side rails. For greater widths storm bars would be required. These storm bars have the option of being removable when hurricane conditions are not present. The 40mm is an attractive slat that is very quiet when rolling up and down. Its light weight makes it perfect for manual gear operation even in larger shutters where the weight of a 58mm or 60mm slat would exceed the capacity of a manual gear. Another advantage of the 40mm is cost. Because of its small profile and light weight, smaller components are required for this shutter making it a very economical Roll Down Shutter,  approved both for FBC and Miami Dade.

 

58mm Extruded Aluminum

F.B.C. Approved

The 58mm is an extruded aluminum end retention slat. The 58mm slat engages the side rails thus allowing the slat span between the tracks to be much greater than with a traditional non end-retention slat. The retention feature makes this slat a perfect choice for large spans such sliding glass doors and enclosing a lanai without the use of vertical storm bars. The 58mm has a slat height of 2.27” and has just the right amount of curve to the face of the slat to allowing it to roll up and down smoothly with a minimal amount space above an opening. A shutter with a finished height of up to 75” would require an 8” housing. Finished shutters between 75” and 125” in height would require a 10” housing and up to 190” would require a 12” housing.

 

60mm Extruded Aluminum

F.B.C. Approved & Miami Dade Approved

The 60mm is an extruded aluminum non-end retention slat. The 60mm is a good choice when Miami Dade approval is required. At 40 p.s.f. the maximum span between side rails is 80”. Greater widths would require the use of storm bars. As with the 40mm slat these storm bars have the option of being removable when hurricane conditions are not present. The 60mm has a slat height of approximately 2.35”. Because of its height and profile the 60mm requires slightly larger housing than the 58mm slat. For example a finished shutter 60” in height would require an 8” housing. Finished shutters between 60” and 102” in height would require a 10” housing and up to 160” would require a 12” housing.
