Paint Paint manufacturers do not warrant their coating products when the Warranty coatings are used as an interior finish. The paint industry has taken the Position position that they have no way of knowing what the intended use of a building interior will be. They also have no way of determining what various environments will be like. This is applicable to all paint finishes such as siliconized polyester, fluoropolymer (Kynar 500), PVC Plastisol, etc. when used as an interior paint coating.

Conversely, the life of an exterior paint finish can be much more readily predicted because paint manufacturers have tested their material in various locations throughout the United States. This field testing has been on-going for many years and has provided manufacturers sufficient evidence of the effect different exterior environments will have on their coatings. Therefore, they are able to offer 10 and 20 year warranties on coating adhesion, and certain degrees of chalk and fade for the exterior finish prorated over a period of time.

Metl-Span’s standard interior paint finish is a siliconized polyester paint coating. We also use this finish on the exterior of our panels and are extended a 20 year standard limited warranty by our paint supplier when the panels are exposed to the outside environment. If we use this same identical finish on the interior face of the panels we are not provided a warranty by our supplier, and therefore cannot extend an interior paint warranty to our customers.

Please be advised that Metl-Span does not offer any warranty whatsoever for paint finishes applied to the interior metal faces of its insulated panels.

Some building interior environments are unusually aggressive or conditions within a building require frequent wash-down of walls and ceilings with chemical cleaners. In these instances, we suggest that you contact us directly for recommendations on other types of finshes or metal substrates, such as stainless steel, that would be better suited for these areas.

Job Site Metl-Span assures the utmost quality in production and shipment of all Panel Storage products. The following must be checked prior to receiving at the job site: Foundation and Steel 1. Panel Storage Customer must have ample storage space to receive packages. This will prevent delays in unloading panels. Area where packages are stored must be level and free from standing water. Panels should be stored in areas with easy access to the location where they will be installed.

2. Foundation and Steel Before receiving panels, customer should check foundation and steel to ensure it is square and level. All support girts must be in place and plumb. Checking these items will help reduce on-site storage and help the installer schedule his panel shipments properly.

All panels are carefully arranged for continuous wrapping. Every precaution is taken to secure placement of panels on trailers or in containers to prevent damage during transport. Damage obtained during shipment should be reported to Metl-Span. Customers should inspect the shipment when received. Carefully check to make sure item numbers on packing list correspond with panels. If there is any variance, please make notes on the bill of lading when signing for delivery approval and contact Metl-Span Shipping Department as soon as possible.

2.1 Job Site Requirements Metl-Span III

Handling and Storage Handling and storage of panels on site should be given extreme care. Label Information Packaging and blocking of panels has been specifically designed so when unloading panels, the forks on a forklift should be placed under center of the package. Metl-Span does not recommend the use of an overhead crane to unload panels. Metl-Span does not take any responsibility for damage obtained from mishandling of panels. Additional Blocks should be placed under the panel blocks to elevate packages for proper drainage, and packages should be slit at the bottom for proper ventilation and to prevent water stains from forming on the panel faces.

Label Information on Packaging

1. Packing list shows contents of each package .

2. Factory Mutual Label for Metl-Span III Panels.

3. Label indicating that panel packages must be slit at base for panel ventilation. 2.2 Fastener Applications Metl-Span III

Proper Use of 300 Series Selection of Fastener Stainless Steel Self-Tapping Screws Since 300 series stainless steel screws cost about three times as much as carbon steel screws, great care should be used to select the proper screw and to apply it correctly to avoid costly screw failure.

Application Guidance

A good grade of carbon steel sheeting screw properly hardened can be carelessly used without damage to the screw. Also, Type A and Type AB carbon steel screws can be used in structural sections of considerable thickness. In addition to this, the same hole size can be used for a wide range of steel thicknesses. This is not true of 300 series stainless steel screws because they cannot be heat treated and they require care in application.

1. Type of Screw

For fastening panel to structure, typically Type B or BP should be used. In light gauge sections (approximately 14 gauge or lighter) Type AB or A can be used.

2. Size of Hole

The following recommendations are based on the assumption that the lighter gauge structural sections (11 gauge and lighter) would be high strength steel - 50,000 psi minimum yield. If ordinary hot rolled steel such as ASTM A-36 is used, the selection of the type of screw and hole size will not be so critical. In heavier sections (3/16” and heavier) it is generally assumed that structural steel ASTM A-36 will be used. Holes should be drilled with 135 degree split point drills as follows:

Sheet to structure for Type B, BP or AB and # 14-10 Type A (See table on page 3.2)

3.1 Fastener Applications Metl-Span III

Proper Use of 300 Series Thickness of Steel Size of Drill Type of Screw Stainless Steel 18 Gauge 3/16” Drill B, BP, AB, A Self-Tapping Screws 16 Gauge #9 Drill B, BP, AB, A

14 Gauge #9 Drill B, BP, AB, A

12 Gauge #3 Drill B, BP

11 Gauge #2 Drill B, BP

Over 11 Gauge thru 3/8” #1 Drill B, BP

Over 3/8” Thickness .231 Drill B, BP

An electric screw gun (approx. 600 rpm) is preferred. High speed impact tools are not good with these stainless steel screws. If they are used, great care must be exercised.

4. Screw Driving Suggestions

The best screws will withstand considerable abuse; however, they can be made to fail, even in the proper hole size.The hole should be drilled perpendicular to the structure and the screw should be driven in the same manner. If the screw is driven at an angle significantly different from which the hole is drilled, thread roll-over is likely. As the thickness of the structure increases, the need for straight drilling becomes more important. If these precautions are not followed, the result may be partially stripped screws which will subsequently loosen with vibration, thus causing leaks.

300 series screws are all made from a special grade of high work harding stainless steel and provide the greatest resistance to thread failure. This includes Type A and AB screws which are frequently used on pre- engineered buildings for fastening sheet to structure. For this application, ordinary 305 stainless Type A or AB screws are not satisfactory because of a high rate of thread failure.

3.2 Fastener Applications Metl-Span III

Proper Installation In areas of high winds, excessive vibration and conditions created by and use of negative pressures due to thermal change, Fab-Lok fasteners should be Fab-Lok Fasteners used. Fab-Loks provide four clamping tines of holding power instead of relying on friction grip screws which may loosen and back-out under the above conditions.

Installation Procedure:

Select the proper Fab-lok for the application.

Size Grip Range Hole Size

10-4 .062”-.250” 3/8”

10-8 .250”-.500” 5/16”

10-12 .500”-.750” 5/16”

A Fab-Lok gun should be purchased from Fabco Fastening Systems for ease of installation. An alternate method of installation may be used, by holding the Fab-Lok sleeve with a 9/16” closed end wrench and turning the screw with a clutch type screw gun. This may be more time consuming therefore, it is worth the expense of a Fab-Lok gun which has the appropriate sleeve holder.

3.3 Installation Tools Metl-Span III

Circular Saw For modification of panel lengths. Carbide blades are required to cut through panel faces and foam.

Power Drill Used for panel fastening and pilot holes through steel girts and panel facings.

Fab-Lok Screw Gun For attaching panels to girts from the building interior for Fab-Lok fasteners.

Reciprocating Saw To trim panels and make window, door and louver openings.

Caulk Gun For applying caulk to panel joints. Rechargeable powered guns are available at building centers.

Power Shears For trimming metal, flashings, gutter, etc.

Hammer Drill For attaching base channel and flashing to the foundation.

Power Nibbler For trimming panel skin and cutting thermal breaks.

Caution: Any metal filings or burrs should be cleaned off the metal surface of panels to prevent rust from forming on the paint. 3.4 Maintenance Metl-Span III

Maintenance and Care Proper installation and maintenance are extremely important in obtaining of Metl-Span the very best service and appearance from pre-painted metal surfaces. Pre-Painted Surfaces The following information should be read carefully before engaging in any of the operations below.

I. Installation and Storage

II. Cleaning of Painted Surfaces

III. Touch-up Repair of Field Surface Scratches

I. Installation and Storage

Pre-Painted formed sheets must be protected from moisture until installation. When metal surfaces are tightly nested together and exposed to moisture and heat, oxidation (rusting) of the metal substrate can begin. In the case of galvanized steel, a white powder will be formed which is the normal sacrificial reaction of the zinc coating. Oxidation of this type can take place underneath the paint film. The following steps should be taken to control this type of storage damage.

1. Keep exterior storage time at the job site to a minimum.

2. Cover and slant bundles of sheets to ensure drainage of rainwater. Make sure no sags exist. Cut outer wrapping to avoid condensation build-up inside package.

Proper handling and stacking should be observed when moving panels to prevent abrasions. During installation, a frequent cause of damage is the dragging of whole panels or edges and corners across other panels. When damage occurs, sacrificial action of the zinc coating will retard red rusting, even if both the paint and galvanized coatings are cut through. If the appearance is damaged sufficiently, a touch-up operation may be necessary.

Improper cutting and drilling of pre-painted surfaces can cause bad rust spotting. Hot chips from drilling operations, saws or cutting discs, may embed in the paint finish.

3.5 Maintenance Metl-Span III

Maintenance and Care Even though panels themselves are not cut, chips from adjacent steel of Metl-Span work may embed in the paint surface. These chips will rust and form Pre-Painted Surfaces unsightly red spots on the painted surface that may become larger than the original chip. When saws, drill or cutting discs are used, the painted surface should be protected with a non-flammable cover. Also, prepainted panels installed next to a panel being cut or any panels nearby should be covered or removed if possible.

Brush off any chips of steel from the painted surface. If they are embedded they should be dislodged mechanically. Brushing with a stiff fiber brush may be adequate. Care should be taken by workmen to avoid stepping on or exerting pressure against any steel chips which tend to get embedded in the paint film.

II. Cleaning Paint Surfaces

Although the factory applied finishes are very durable and will last many years, eventually it may be desirable to thoroughly clean or repaint them.

Dirt build-up may cause apparent discoloration of the paint when it has been exposed to dirt laden atmospheres for long periods of time. Slight chalking may cause some change in appearance in areas of strong sunlight. A good cleaning will often restore the appearance of these buildings and render repainting unnecessary. An occasional light cleaning will help maintain a good appearance.

In many cases, simply washing the building with plain water using hoses or pressure sprays will be adequate. In areas where heavy dirt deposits dull the surface, a solution of water and detergent (1/3 cup Tide per gallon of water for example) may be used. A soft bristle brush with a long handle may be useful. A clear water rinse should follow. Mildew may occur in areas subject to high humidity, especially on dirt and spore deposits. This is not normally a problem on clean surfaces, however, due to the high inherent mildew resistance of baked-on finishes. To remove mildew the following solution is recommended:

1/3 cup detergent (e.g. Tide)

3.6

Maintenance Metl-Span III

Maintenance and Care 2/3 cup tri-sodium phosphate (e.g. Soilex) of Metl-Span Pre-Painted Surfaces 1 quart sodium hypochlorite 5% solution (e.g. Clorox)

3 quarts water

Strong solvents and abrasive type cleaners should be avoided. Caulking compounds, oil, grease, tars, wax and similar substances can be removed by wiping with a cloth soaked with mineral spirits. Wipe only contaminated areas and follow with detergent cleaning and thorough rinsing.

III. Touch-up Repair of Installed Surface Scratches

1. Surface Preparation:

A. Edges of deep scratches should be lightly sanded or feathered with #400 grit sand paper. B. Scratches and areas immediately adjacent should be wiped with lint free cloth dampened in mineral spirits. C. Allow area to dry thoroughly before applying touch-up.

2. Touch-up Application:

A. Check touch-up paint for correct match before applying to damaged areas. B. Shake and stir paint before applying. C. Apply touch-up paint to damaged area in thin coatings at a time.

3. Precautions:

A. Protect eyes, face and hands from direct contact with touch-up paint and /or solvents. B. Provide good ventilation in work area. C. Enforce NO SMOKING. Remove all sources of ignition. These coatings and solvents are FLAMMABLE.

3.7 Installation Metl-Span III Procedures Wall Panel Joint Installation Procedure

To ensure a proper vapor barrier and water tightness apply 1/4” bead of sealant in both grooves of the panel for commercial and industrial buildings. For cold storage buildings the sealant should be applied in the female groove of the Warm Side Wafer Head exterior surface of the panel.
