SEAM-LOC 24

The application and detail drawings in this manual are strictly for illustration purposes and may not be applicable to all
building designs or product installations. All projects should conform to applicable building codes for that particular area. It
is recommended to follow all building regulations and standard industry practices.

Metal Sales Manufacturing Corporation is not responsible for the performance of the roof system if it is not installed in
accordance with the suggested instructions referenced in this manual. If there is a conflict between this manual and the Metal
Sales approved erection drawings, the approved erection drawings are to take precedence.

Prior to ordering and installing materials, all dimensions should be verified by field measurements.

Metal Sales reserves the right to modify, without notice, any details, recommendations, or suggestions. Any questions
you may have regarding proper installation of the Seam-Loc 24 roofing system should be directed to your Metal Sales
representative, (see pages 2 and 3).

Oil canning is not a cause for rejection. Oil canning can be described as the amount of waviness found in the flat areas of metal
panels. Oil canning is an inherent characteristic of light gauge cold formed metal products, particularly those with broad flat
areas. There are many factors which may contribute to oil canning that Metal Sales is not able to control. These factors
include: misalignment of the support system, over driving of fasteners used on the panels, stress (whether inherent in the panel or
induced), thermal expansion and contraction of the panel, material handling, width, gauge, length, color of panels, and installation
(Reference Metal Construction Association “Oil Canning Position Paper” - Appendix A).

Exposure of metal roof and wall materials to areas subject to corrosive, harmful and aggressive environment condition but not
limited to salt water regions, marine atmosphere, repeated salt spray, corrosive chemical, ash, fumes, chemical dust, corrosive
vapors, animal waste, confinement, run off from non-compatible metal, can cause premature rusting and other failure of metal
materials (including panels and trims) and therefore is not a cause for claim or rejection.

IMPORTANT INFORMATION

Consult Metal Sales representative for any additional information not outlined in this manual (see pages 2-3).

This manual is designed to be utilized as a guide when installing Seam-Loc 24 roofing system. It is the responsibility of the
erector to ensure the safe installation of this product system.

SAFETY

STUDY APPLICABLE OSHA AND OTHER SAFETY REQUIREMENTS BEFORE

FOLLOWING THESE INSTRUCTIONS.
The installation of metal roof systems is a dangerous procedure and should be supervised by trained
knowledgeable erectors. USE EXTREME CARE WHILE INSTALLING ROOF PANELS. It is not possible
for Metal Sales to be aware of all the possible job site situations that could cause an unsafe condition
to exist. The erector of the roof system is responsible for reading these instructions and determining
the safest way to install the roof system.

These instructions are provided only as a guide to show a knowledgeable, trained erector the correct
parts placement one to another. If following any of the installation steps would endanger a worker, the
erector should stop work and decide upon a corrective action.

Provide required safety railing, netting, or safety lines for crew members working on
the roof.

Do not use the roof panel as a walking platform. The roof panels will not withstand the weight of a
person standing at the edge of the panel.

Do not stand on the roof panel at the ends until the panels have been attached.

RECEIVING MATERIAL

It is the responsibility of the installer to unload material from the delivery truck. The installer shall be responsible for providing
suitable equipment for unloading of material from the delivery.

After receiving material, check the condition of the material, and review the shipment against the shipping list to ensure all
materials are accounted for. If damages or shortages are discovered, it should be noted on the Bill of Lading at the time of delivery.
A claim should be made against the carrier as soon as possible. Metal Sales is not responsible for any damages or shortages unless
they are documented in writing and presented to Metal Sales within 48 hours.

GENERAL HANDLING

Each bundle should be handled carefully to avoid being damaged. Care should be taken to prevent bending of the panel or abrasion
to finish. Whenever possible, the bundle should remain crated until it is located in its place of storage. If bundles must be opened,
we recommend you recrate them before lifting. To avoid damage please lift the bundle at its center of gravity.

HANDLING MATERIAL

CAUTION

Improper loading and unloading of bundles and crates may result in bodily harm and/or

material damage. Metal Sales is not responsible for bodily injuries and/or material

damages resulting from improper loading and unloading.

MECHANICAL HANDLING

Forklift - A forklift may be used for panels up to 20'-0" long. Please make sure the forks are at their maximum separation. Do
not transport open bundles. When transporting bundles across rough terrain, or over a longer distance, some means of supporting
the panel load must be used.

Crane - A crane should be used when lifting panels with lengths greater than 20'-0". Please be sure to utilize a spreader bar to
ensure the even distribution of the weight to the pick up points. As a rule when lifting panels, no more than 1/3 of the length of the
panel should be left unsupported. Never use wire rope because this will damage the panels.

SEAM-LOC 24

MANUAL HANDLING

When handling painted steel care should be taken to prevent scratching of material. Clean gloves should be worn at all times
to prevent a reaction with salts found on bare skin. Installers should wear rubber sole shoes to keep from scuffing material
while walking on the roof.

Handling of individual panels should be done carefully and properly to avoid bending or damaging. Seam-Loc 24 panels should be
carried by grasping the edge of the panel so that the Seam-Loc 24 panel is vertical to the ground. The Seam-Loc 24 panel should
not be carried with the panel horizontal to the ground as this could cause the panel to buckle or bend in the center.

Normally individual panels can be handled by people placed every 6'-0" to 8'-0" along the length of the panel.

SEAM-LOC 24

GENERAL

Please inspect panels for moisture accumulation. If moisture has formed, the panels should be unbundled, wiped dry, and allowed
to dry completely. Once dry, carefully restack the panels and loosely recover allowing for ample air circulation.

Bundled sheets should be stored high enough off of the ground to allow for air circulation and prevent contact with accumulating
water. If possible, elevate one end of the bundle to allow any moisture to run off the panels. Metal Sales recommends covering the
bundle with a tarpaulin. Do not use tight fitting plastic-type tarpaulins as panel bundle covers. While they may provide protection
from heavy downpours, they can also retard necessary ventilation and trap heat and moisture that may accelerate metal corrosion.
If panels are to be stored in possible bad weather, we suggest they be stored inside. Extended storage of panels in a bundle is
not recommended. Under no circumstances should the sheets be stored near or come in contact with salt water, corrosive

chemicals, ash, or fumes generated or released inside the building or nearby plants, foundries, plating works, kilns,
fertilizer, and wet or green lumber. These conditions will cause premature rusting of panels.

SEAM-LOC 24

STORAGE ON ROOF

To facilitate the handling of Seam-Loc 24 panels, panel bundles can be lifted and placed on the roof. Bundles need to be placed on
the roof in order for the roof structure to handle the weight. Loading capabilities of the structure must be checked.

When lifting packaged sheets, make certain they are adequately supported. Panels less than 20'-0" in length can normally be lifted
with a forklift; however, when lifting panels in excess of 20'-0", it is recommended that a spreader bar and slings be used. As a
rule, when lifting, no more than 1/3 of the length of the panel should be left unsupported.

Make a plan for bundle placement by determining how much area a bundle of panels will cover. Bundles should be placed on the
roof in accordance with the direction the panel will be installed. Consider where the string line, if any, is to run at the eave to set
roof panels by. Roof bundles should not interfere with this string line.

Care of metal panels and flashings must be exercised throughout erection. Foot traffic can cause distortion of panel and damage
to finish. Traffic over the installed system must be kept to an absolute minimum. If continuous foot traffic is necessary for
maintenance over certain areas of the roof, then a permanent walkway should be installed.

If metal panels are installed over open framing, do not use the roof panel as a walking platform. The roof panels will not
withstand the weight of a person standing at the edge of the panel. Provide walking platforms to avoid any panel damage as
shown below.

When walking on the roof panels is unavoidable, walk only in the flats of the panel. Walking on the ribs can cause damage
to the panels. If Seam-Loc 24 is installed over open framing, step in the flat of the panel only and as close to the framing
as possible.

SEAM-LOC 24

FIELD CUTTING

Tin snips or a "nibbler" type electric tools are recommended for field cutting Seam-Loc 24 panels. Cutting the steel generates
slivers or metal chips. These slivers and metal chips must be immediately removed from the Seam-Loc 24 panels because they will
damage the finish and shorten the life of the product.

One method of preventing this problem is to flip the Seam-Loc 24 panels over when cutting. This allows the slivers and metal
chips to be brushed from the back side and avoids damaging the paint on the top side of the panels.

When cutting Seam-Loc 24 panels, goggles must be worn for eye protection.

FIELD CUTTING AND TOUCH-UP

CAUTION

All product surfaces should be free of debris at all times. Installed surfaces should be

wiped clean at the end of each work period. Never cut panels over metal surfaces.

Metal shavings will rust on the surface, voiding the warranty.

TOUCH-UP PAINT

All painted panels and flashings have a factory applied baked on finish. Handling and installing panels may result in some small
scratches or nicks to the paint finish. Touch-up paint is available in matching colors from Metal Sales. It is recommended that a
small brush be used to apply touch-up paint to those areas that are in need of repair. Touch-up paint does not have the superior
chalk and fade resistance of the factory applied paint finish and will normally discolor at an accelerated rate. Aerosol paint should
not be used because of the overspray that may occur.

DESIGN / INSTALLATION CONSIDERATIONS

TECHNIQUE

Recommended Tool Type - Use depth locating nose or adjustable clutch on screw gun to prevent overdrilling and strip out.
Do not use impact tools or runners.
Seating the washer - Apply sufcient torque to seat the washer - do not overdrive the fastener.

CORRECT

Sealing material slightly visible

at edge of metal washer.

Assembly is watertight.

SELF DRILLER

WOODSCREW

TOO LOOSE

Sealing material is not visible;

not enough compression to

seal properly.

TOO TIGHT

Metal washer deformed;

sealing material pressed

beyond washer edge.

To prevent wobbling - Make sure fastener head is completely engaged in the socket. If the head does not go all the way in
the socket - tap the magnet deeper into the socket to allow full head engagement. Metal chips will build up from drilling and
should be removed from time to time.

Protect drill point - Push only hard enough on the screw gun to engage clutch. This prevents excess friction and burn out of the
drill point. Correct pressure will allow screw to drill and tap without binding.

Drilling through sheet and insulation - Ease up on pressure when drilling through insulation to avoid striking the purlin or girt
with the point - apply more pressure after drill point contacts purlin or girt.

Drilling through purlin overlaps - Drilling through lapped purlins requires extra care. Excessive voids between purlins
sometimes damages drill points and two self-drillers might be necessary to complete the operation. It is sometimes advantageous
to predrill.

CONDITION OF SUBSTRUCTURE

Whether over solid substrate or open structural framing, panel distortion may occur if not applied over properly aligned and
uniform substructure.

The installer should check the roof deck for squareness before installing Vertical Seam panels. Several methods can be used to
verify squareness of the structure for proper installation of the panels.

METHOD "A" - One method for checking the roof for squareness is to measure diagonally across one slope of the roof from
similar points at the ridge and eave and obtain the same dimension.

METHOD "B" - The 3-4-5 triangle system may also be used. To use this system measure a point from the corner along the edge
of the roof at a module of three (3). Measure a point from the same corner along another edge at a module of four (4). Then by
measuring diagonally between the two points established, the dimension should be exactly a module of five (5) to have a square
corner. Multiple uses of this system may be required to determine building squareness. If the endwall cannot be made square, the
roof system cannot be installed as shown in these instructions.

VENTILATION

Proper design and installation of vapor barriers and ventilation systems are important to prevent condensation and the resulting
problems of moisture damage and loss of insulation efficiency.

Condensation occurs when moisture laden air comes in contact with a surface temperature equal to or below the dew point
of the air. This phenomenon creates problems that are not unique with metal buildings; these problems are common to all
types of construction.

The underside of the metal roof on a typical metal building (no attic) should be protected from condensation by insulating with a
faced insulation. This should reduce the potential of condensation forming on the underside of the panels.

On buildings that have an attic space or are being retrofitted with a metal roofing system, vents should be placed at both the eave
and peak of the roof in order to prevent a buildup of moisture (humidity) in the attic space.

INSULATION

In most cases insulation is installed directly under roof panels. Insulation is recommended on all applications to act as a sound
barrier, prevent condensation, and increase insulating value of a roof system.

Many different types of insulation can be used with the metal roof panels. Please contact your insulation supplier for specific
recommendations on installation of insulation and vapor barriers.

When applying a compressible type of insulation over open framing members. Rigid thermal blocks can be used to help eliminate
heat lost at purlin locations.

CAUTION

Use extreme care when working next to insulation. The insulation will provide a false sense of

security by hiding the view of the ground below the insulation.
