Approved for 200+ Hurricane Winds.
How to Determine the Correct Slat
Our shutters are tested and approved in accordance with all current
certification authorities to provide hurricane protection. Our shutters
pass all current state codes for hurricane protection.

We are approved by:
- Dade County
- FBC (Florida Building Code)
- TDI (Texas Department of Insurance)
Deciding how to select the right shutter for your application.
Currently there are numerous wind load specifications established
and accepted by different counties through out the U.S. There is
no single adopted windload chart accepted, so each installation
needs to check with the local county, state, or governing body to
establish the correct wind load table. Check with your local building
inspector for the applicable code.
QMI does not provide, or specify for construction, design criteria
for windload design pressure specifications for any structure. This
is only done by a qualified licensed structural engineer.
Please check the design requirements required by a structural engineer.
We have this engineering service available for a fee.
