40mm Bertha Extruded Aluminum Roll-Up Shutter manufactured by

Alutech United, Inc.
15 Dixon Street
Selbyville, DE 19975
(800) 233-1144


will be accepted for use in designated catastrophe areas along the Texas Gulf Coast when installed in accordance with this product evaluation along with Drawing No. 02-429, sheets 1-12 of 12, prepared by Walter Tillit, Jr., P.E., dated September 12, 2002, signed by Walter Tillit, Jr., P.E. on October 4, 2002.

PRODUCT DESCRIPTION

The 40mm extruded aluminum roll-up shutter is a 6063-T6 aluminum alloy permanently mounted impact protective system. The aluminum slats have a total width of 1.870" and a depth of 0.382" and a typical wall thickness of 0.043". The slats are mounted with the following components; the header, the mullions, track, the reel box assembly and storm bars. The overall horizontal span of the system can be increased by the use of storm bars that create multiple spans. Consecutive single spans and multiple spans are connected with mullions. All aluminum extrusions shall be 6063-T6 aluminum alloy. The shutters may be wall mounted, inside mounted, mullion mounted, build-out or any combination thereof.

LIMITATIONS

Design Wind Pressure: ±40 psf

Maximum Span:
Maximum Slat Span:
The maximum slat span shall be 50".
Maximum Storm Bar Span: The maximum horizontal span of the system depends on the storm bar spacing, the design pressure (40 psf minimum) and the storm bar type. The "Storm Bar Loading Chart" on sheet 10 of 12, Drawing No. 02-429, is used to determine the maximum span of the storm bars. The storm bar spacing shall not exceed the maximum slat span.
Maximum Mullion Span: The maximum span of the shutter system with consecutive spans and/or multiple spans is dependent on the mullion span which is determined using the "Mullion Loading Chart" on sheet 12 of 12, Drawing No. 02-429. The mullion span is determined from the design pressure (40 psf minimum), the type of mullion and the mullion spacing. For mullions installed with storm bars, the mullion spacing shall not exceed the maximum slat span. For mullions installed without storm bars and headers, the mullion spacing shall not exceed the maximum header span and the storm bar spacing shall not exceed the maximum slat span.
Maximum Header Span: The maximum horizontal span of the header depends on the type of header, the design pressure (40 psf minimum) and the storm bar height. The maximum span of a header is determined using the "Header Loading Chart" on sheet 11 of 12, Drawing No. 02-429.

Height Limitations:
Inland II Zone:
The product shall not be installed on buildings with a height greater than 50 feet above natural grade.
Inland I Zone: The product shall not be installed on buildings with mean height greater than 33 feet above natural grade.
Seaward Zone: The product shall not be installed on buildings with mean height greater than 33 feet above natural grade.
Impact Resistance: This shutter assembly satisfies the Texas Department of Insurance’s criteria for protection from windborne debris.
