Hurricane Entry Doors

All Donatello doors provide effective protection against extreme storm damage, strong winds and debris impact. The only required modification is the addition of HVHZ certified laminated glass, instead of our dual pane glass with argon gap. You can have exactly the same elegant designs and your required architectural look without compromising on safety. We build both home entry doors and commercial entry doors to the required HVHZ standard.

High Velocity Hurricane Zone Iron Doors for Florida, Louisiana, Texas, Georgia and South Carolina

In August 2013 we achieved product approval from the Florida department of Business & Professional Regulation for supply of Swinging Exterior Door Assembles into HVHZ areas. Our contract with the Quality Assurance entity, the National Accreditation & Management Institute (NAMI), expired in December 2016 and so our certification is not current.

ALTHOUGH OUR CERTIFICATION IS EXPIRED, it is still possible to gain local approval from your building department based on the tests completed. We will work with your local engineer to provide the required engineering data for certification.

Our HVHZ testing data includes a structural design pressure test of 105 pounds per square foot (psf), for winds up to 160 mph and impacts by both large and small debris. Doors were subjected to three impacts by a 2X4 wooden stud travelling at 50 ft/sec, followed by rapidly changing positive and negative pressures up to 70 psf.

Hurricane Tracks

Atlantic hurricanes are cyclones that form in the North Atlantic Ocean, usually in the summer or fall. Hurricanes are classified in intensity using the Saffir–Simpson hurricane scale (SSHS) for short. There are five categories, distinguished by the intensities of their sustained winds.
On average, in the North Atlantic basin, 11.3 named storms occur each season, with an average of 6.2 becoming hurricanes and 2.3 becoming major hurricanes (Category 3 or greater). Hurricane activity usually peaks in the early part of September.

Our rated Hurricane Doors are built with special steel and materials to offer highest security in all these severe weather conditions and yet these are easy to operate.

Here is a table of categories with wind speeds and effects published by the Office of Homeland Security:
CAT Winds & Effects Surge
1 74-95 mph 4-5 ft
No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Also, some coastal flooding and minor pier damage.
2 96-110 mph 6-8 ft
Some roofing material, door, and window damage. Considerable damage to vegetation, mobile homes, etc. Flooding damages piers and small craft in unprotected moorings may break their moorings.
3 111-130 mph 9-12 ft
Some structural damage to small residences and utility buildings, with a minor amount of curtainwall failures. Mobile homes are destroyed. Flooding near the coast destroys smaller structures with larger structures damaged by floating debris. Terrain may be flooded well inland.
4 131-155 mph 13-18 ft
More extensive curtainwall failures with some complete roof structure failure on small residences. Major erosion of beach areas. Terrain may be flooded well inland.
5 155 mph+ 18 ft +
Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. Flooding causes major damage to lower floors of all structures near the shoreline. Massive evacuation of residential areas may be required.
