General Shutter Specifications

 

Specifications

The Aluminum Construction Manual, Specifications For Aluminum Structures, the Aluminum Formed Sheet Building Sheathing Design Guide, the Engineering Data For Aluminum Structures, and The Commentary on Specifications For Aluminum Structures, published by the Aluminum Station, Inc. in Washington, D.C. are used as reference material.

Applicable ASTM specifications are designations B209, B211, B234, B241, B247, B308, and B249.

Extrusions used herein shall be 6063 T-6 aluminum, registered with the Aluminum Association. Inc. - Washington, D.C.. unless otherwise noted.

Deflections

The deflection limits of structural aluminum members set forth shall be applicable, and conform to the Standard Building Code, the South Florida Building Code - maximum of 1" deflection - L/30.

The allowable stresses for aluminum members shall be as given in specifications for Aluminum Structures published by the Aluminum Association, Inc. - Washington, D.C.

Tolerances

The specified minimum thickness of extruded aluminum, aluminum coil products, and other applicable materials as detailed shall be the nominal thickness, find is subject to the tolerances published in the Aluminum Standards and Data, Aluminum Association, Washington, D.C.

Safety Factors

All engineering calculations used in conjunction with this design shall be based on a safety factor in accordance with table 3.3.3 of the Aluminum Construction Manual Series, section 1.

Shape Factors

Non-Coastal zones, class 1 and 2 buildings -1.1.
Coastal zones. class 1 buildings -(end zones) -1.3
Coastal zones, class 2 buildings -(end zones) -1.9

All calculations used are based on the South Florida Building Code 1988 Edition, Chapter 23, Section 2303.3 (i) and 2309.2.

Materials

Aluminum roll-formed panels shall be 3004-Hl6 alloy. Steel roll-formed panels shall be galvanized and have ASTM A-525 designation. Aluminum bolts shall be 2024-T4 alloy.

Dissimilar Materials

Where the aluminum alloy sections are in contact with, or are fastened to, steel members or other dissimilar materials, the aluminum shall be kept from direct contact with the steel or other dissimilar material painting.

Steel surfaces to be placed in contact with aluminum shall be painted with good quality, non-lead contaminating, priming point such as zinc chromate primer in accordance with Federal Specification TT-P-645, followed by two coats of plain consisting of two pounds (2 lbs.) of aluminum paste pigment, ASTM Specification D962-66, Type 2, Class B, per gallon of varnish meeting Federal Specification TT-V-81, Type 11, or the equivalent. Where severe corrosion conditions are expected, additional protection can be obtained by applying a suitable sealant to the fayng surfaces, capable of excluding moisture from the joint during prolonged service in addition to the zinc chromate primer. Aluminized, hot-dip galvanized or electrogalvanized steel placed in contact with aluminum need not be painted. Stainless steel (300 series) placed in contact with aluminum need not be painted except in high chloride containing environments.

Aluminum should not be placed in direct contact with wood, fiberboard or other porous material that may absorb water and 40 cause corrosion. When such contacts cannot be avoided, an insulating barrier between the aluminum and the porous material shall be installed. Aluminum or other coating providing equivalent protection before installation. Aluminum in contact with concrete or masonry should be similarly protected in cases where moisture is present and corrodents can be entrapped
the surfaces.

Prepainted aluminum generally does not need additional painting, even in contact with other materials such as wood, concrete or steel. Under (extreme) corrosive conditions. additional protection may be provided as described In the preceding sections.

GENERAL CONSTRUCTION REQUIREMENTS

All fastenings, unless specified differently, shall be a maximum of twenty four inches (24") on center. Aluminum, hot-dip galvanized, electro-galvanized, aluminized steel, 300 series stainless steel, or corrosion resistant fasteners may be used, or as specified by local codes and ordinances.

Concrete anchors must be embedded a minimum of one and one quarter Inches (1-1/4) into the structural concrete, and tightened property. A longer fastener shall be required in the event that deck toppings, coatings, tile, brick or pavers are used, as these surfaces do not have to required holding ability.

Anchor types shown shall meet or exceed the safe working values as specified by the manufacturer. Any substitutions must follow these requirements.

Any fastener stripped or not adequately holding must be replaced.
