1. GENERAL
1.1 Product Description
MetalWorks Linear is a metal ceiling system that utilizes linear planks that are available 96" long and in 4", 6", 8", and
12" widths. All planks include a 1-1/4" plank flange that can optionally be covered with a black plastic filler strip to create the Contrasts visual. Linear planks are made of 0.028" thick electrogalvanized steel. Their post-production, powder-coated finish is available in White, Silver Grey, Gun Metal Grey, Effects ™
Wood Looks finishes, and a wide range of custom colors.
Microperforated options with a plain border, acoustical fleece backing, and optional fiberglass infill are available.
The Main Beam Carriers used to suspend the planks are directional and have hanging features at 2" increments. All plank widths can be installed on the same carrier system which allows for design and installation flexibility.

1.2 Storage and Handling
The ceiling planks shall be stored in a dry interior location and shall remain in cartons prior to installation to avoid damage. The cartons shall be stored in accordance with the instructions on the carton. Proper care should be taken when handling to avoid damage or soiling.
1.3 Ceiling Plank Layout
The ceiling plank layout should have perimeter planks equal in width on opposite ends. These cut perimeter planks should be more than 50% of their original width. See BPLA-295518 for
MetalWorks cutting instructions. If the plank is less than 50% of the original width, divide the room dimension by the nominal width of the plank (4", 6", 8", or 12"). Determine the remainder, add one full plank width, and divide by two to determine the width of the border plank.
Example: 8" nominal plank width, room dimension 10' 4".
Divide 10' 4" by 8" = 15 full sections with 4" remainder. Add 4"
+ 8" = 12". Divided by 2 = 6" border plank with 14 full rows of planks. This will create the best visual and installation.
2.6 Pre-bending Hanger Wires
Stretch a string line or set a laser at the bottom of the molding from one side to the other along a row of hanger wires. Bend the wires 2" above the string or laser.
2"
2. SUSPENSION SYSTEM INSTALLATION
2.1 Perimeter Molding
Install the Carrier Molding (5574) on the perimeter walls.
Molding should be secured to the wall every 16 to 24 inches.
The bottom of the molding is the finish height of the linear plank.
2.7 Squaring and Cutting the Main Beam Carriers
Stretch a string line from one side of the room to the other at the bottom of the molding (string perpendicular to the Carrier).
The string should be out from the "end" wall by the calculated width of the first "plank." Refer back to Section 1.3 for width of border planks.
2.7.1 Measure from this string to the wall. Cut the first Main
Beam Carrier in each row so the desired notch lines up with this string.
NOTE: The system can also be squared by measuring a 4' x 4' diagonal opening, as with installing a normal DGS ceiling.
2.2 Hanger Wires
Secure hanger wires to the structure above to support the
Main Beam Carriers. Wire spacing for Main Beam Carriers should be within 24" of the perimeter wall and then 48" OC.
2.3 Main Beam Carriers
The Main Beam Carriers will be installed 48" OC perpendicular to the desired plank length direction. The first and last Main
Beam Carrier must be installed within 24" of the perimeter wall.
2.4 Main Beam Carriers are directional and must be installed accordingly. Main Carriers splice together with Superlock end detail just like standard drywall grid main beams.

3. PLANK INSTALLATION
3.1 Starting Perimeter Row
Measure from the wall to the string several places and determine the exact width of the first row of planks.
3.1.1 Mark the plank and cut to width. The 1-1/4" flange edge is the edge that should be cut off.
3.1.2 Slide the cut edge of the plank into the perimeter wall molding. The opposite hook edge (factory edge) of the plank will fit onto the tab on the carrier.
3.1.3 Insert pressure springs and/or pop rivet plank to secure the plank to the molding; frequency of pressure springs or pop rivets is as necessary, but typically 24" OC.

Retaining flange edge
3.1.5 Cut the planks to length to fit into the perimeter molding at the sides parallel to the carrier. Use pressure springs on ends as needed.
3.1.4 The Cut Plank Support Bracket (CPSB - BP7237) can be used as an optional method to secure planks to the carrier system when one of the plank’s factory engagement edges has been removed. The function of the bracket is to keep the remaining factory edge of a cut plank engaged in the carrier, while the cut edge is supported by the carrier molding.
The CPSB is intended to replace the use of visible pop rivets into the bottom flange of the carrier molding.
The same bracket can be used to secure cut planks that retain the hook edge or that retain the flange edge (see details).
To install the CPSB:
1) Cut and install the planks as described in sections 3.1
(retaining hook edge) or 3.4 (retaining flange edge)
2) Install pressure springs as outlined previously
3) If installing a plank with the hook edge remaining, install the
CPSB before installing the second row of planks. If installing a plank with the flange edge remaining, install the second row of planks before attaching the CPSB.
4) Place the CPSB against the side of each carrier (4' OC) so that it engages the cut plank (as shown below)
5) Attach the CPSB to the carrier with two #8 1/2" framing screws through the holes in the CPSB that align with the notches in the carrier.
3.2 Plank Splices
When 4", 6", and 8" planks do not reach across the space in one piece, use a plank splice (available in 4", 6", and 8", widths) to join and align adjacent planks. Install planks so the factory ends are at the splice locations and assure the joint is tight. Install the splice by inserting the solid end under the plank hook. Then gently push the finger side down on the opposite side to lock the plank joints together.
Retaining hook edge
3
Planks 12" wide have a factory return on the ends and have two options to splice the planks when they do not reach across the space in one piece. Install planks so the factory joint is tight and use vise grip pliers to temporarily hold together.
Option 1 – Insert speed clips (item 6351) over the two plank returns. Use one hand to support the plank face and the other hand to snap the speed clip on the returns. Two speed clips are required at each joint.
Option 2 – Insert sheet metal framing screws through the plank returns. This requires a clear plenum to work with power tools above the plank. Two screws are required at each joint.
3.5 Last Full Plank Width Row
The last full row of 4", 6", or 8" planks must be joined end-toend after installation, but must be prepared before installation
(for 12" planks see Section 3.5.8)
3.5.1 Cut a scrap piece of plank as shown below (4-6" length).
Nest this piece into the flange of the first plank to be installed in the last row and pop rivet, as shown below. This is the end of the plank that does not rest on the wall molding.

Pop Rivet
3.3 Field Plank Installation
Install the second row of planks by inserting the flange edge on top of the previous plank. Next, gently push the plank hook side up until it snaps onto the carrier tab. Continue installing planks until you reach the other side of the room.
Pre-drilled hole
Pop Rivet
3.4 Last Perimeter Row
Do not install the last row of full width planks at this time. Cut the perimeter row of planks to width based on the border plank size calculated previously. Take the measurement as shown below and transfer this to the face of the planks. Cut the planks to retain the flange side.
Use pliers to bend the carrier tab out 90 degrees. Next, insert the long cut edge of the plank into the molding, align the plank in the carrier, and use pliers to bend the supporting tabs back to the original position.Insert pressure springs or pop rivets to secure the border planks to the molding as shown in section 3.1.3.
3.5.2 Align another section of the plank with the end of the one just prepared and drill a hole for the pop rivet in the second plank of the row, but do not install the rivet.
3.5.3 Install the first plank in the ceiling by inserting the flange edge on top of the previous plank. Next, gently push the plank hook side up until it snaps onto the carrier tab.

3.5.4 Cut the fingers off of a splice plate and secure it into the end of the installed plank with a piece of two-faced tape.
3.5.5 Prepare the third plank in the row as described in Section
3.21.1 and 3.21.2 above. Install the second plank in the row and insert the pop rivet in the holes prepared in Section 3.21.2.
3.5.6 Continue this pattern for the remainder of the row. The splice plate installed in the next to last plank can only extend about 1/2" into the end of the last plank in the row.

3.5.7 Color the exposed rivets to match the plank finish.
3.5.8 To install the last full plank width row of 12" planks
Cut the first plank to length so the end return will be at the middle of a carrier channel. Install the plank flange edge as normal and then gently push the plank hook side up until it snaps onto the carrier tab. The splice will be directly under the carrier channel to keep the joint aligned. Carriers are installed on 4' centers, and the remaining plank joints should be at carrier channel.
NOTE: Screws can be added through the upturns to keep the planks tightly together (as shown in detail below).
4.1 Faceting the Main Beam Carriers
A MetalWorks Linear curved system is actually a faceted application with a 4", 6", 8", or 12" facet depending on the plank width. To curve or facet the Main Beam Carrier, snip the small vertical section between plank tabs and through the web to the flange. Use RC2 clips to reinforce the cuts in the Main
Beam Carrier per the Curved Drywall Grid Technical Guide,
BPCS-3540.
Add #8 screw as necessary to ensure there is at least one screw connection between all RC2 clips.
Snip Main Carrier at notches based on plank size.
Optional screws

Molding
3.6 Optional Plank End Caps
Plank end caps can be used when the plank end is not covered by a molding. This may occur at a ceiling penetration or custom perimeter treatment, such as a floating installation.
The plank end must be cut square and clean. Press the cap into the plank until it is flush with the end.
4.2 The carrier molding is used at the perimeter of curved linear metal installations. The carrier molding is not flexible and it is to be notched in the field for curved applications.
4.3 Perpendicular to the Carrier
On the two sides that the molding runs perpendicular to the modified carriers, it can be attached to the carriers as detailed in section 2.8 Main Beam Carrier Attachment. Use pressure springs to keep the plank tight in the carrier molding.
3.7 Optional Contrasts Fillers (item 5494)
Nominal 1-1/4" wide black Contrasts filler strips are field applied to planks before installation. Slide the filler hem over the plank flange. Install the plank as usual.
4.4 Perpendicular to the Linear Planks
The molding along the curved end will need to be faceted to match the plank width – 4", 6", 8", or 12". Cut a V-notch on the top flange at the module length. This will provide clearance to make a vertical cut on the side. Attach the molding to the wall to match the elevation of the planks. Use pressure springs to keep the plank tight in the flex carrier molding.

4.6.1 MetalWorks Linear can be installed to create a curved transition from ceiling to wall by faceting the Main Beam
Carriers.
Radius minimums:
• 12" plank – 6' radius
• 8" plank – 4' radius
• 6" plank – 3' radius
• 4" plank – 2' radius
See Section 4. CURVED INSTALLATIONS for instructions on how to facet Main Beam Carriers.
4.6.2 Use Rigid Attachment Clips (item 6459BL) or QSUTC to stabilize the Main Beam Carriers. Install hanger wires to deck
6" from wall, then 24" OC along the curved segment of the
Main Carriers. Install planks with flange down starting from the bottom.
4.6.3 MetalWorks
™
Linear curved transitions are single wall only, due to the directional attachment of the planks.
4.5.1 MetalWorks
™
Linear planks can only be installed on the wall horizontally. Install Rigid Attachment Clips to furring strips or 5/8" plywood, securing them with appropriate fasteners for the substrate. pacing between clips along the Main Carrier should not be more than 24". The first row of clips at the bottom should be elevated from the floor by no more than 6".
The last row of clips at the top should be within 6" from the existing ceiling.
4.5.2 Install the Main Beam Carrier directly to the clips 48" on center. The first and last carrier must be within 8" from the end to control plank twist. Install the planks with the flange facing down starting at the bottom going up.
4.5.3 Install splice plates at plank joints. Splice plate installation will be blind because of proximity to the wall structure.
4.5.4 If not wall-to-wall, use end caps on planks, but all other components may be in line of sight.

5. PLANK PENETRATIONS
5.1 Penetrations through linear metal planks are made using typical metal working equipment. Hole saws work well for sprinklers. Tin snips can be used for larger openings. All penetrations should be fitted with escutcheons that conceal the cut plank edges.
5.2 Planks are not to be used to support the weight of ceiling mounted hardware. These items are to be supported from the
Main Beam Carriers or directly from the overhead structure.
6. ACCESS PANELS (INTERIOR ONLY)
6.1 Access panels must be installed at each location where entry through the ceiling is required. Maximum access panel size is 36" wide by 36" long. Plan size and location carefully to ensure that all above ceiling equipment requiring service is reachable.
6.2 Access Panel Opening
Make sure that a carrier is installed not more than 12" from each end of the openings. If sections of carrier must be added, they should extend at least one full plank width beyond the sides of the openings.
6.3 Frame the opening with sections of Carrier Molding (item
5574) to match the size of the opening. Fasten the backside corners of the frame overlap with metal framing screws.
6.3.1 Pop rivet the frame to the cut planks 6" from all corners and 12" OC to hold the frame in place.
6.4 Access Panel Construction
Fabricate a second frame for the access panel out of the
Carrier Molding. Size this frame 1/2" smaller, in both directions, than the ceiling opening.
6.5 Cut lengths of plank to fill the frame, making sure that they will line up with the planks in the field of the ceiling. Pop rivet the long side of the planks to the inside of each end of the frame 6" in and 12" OC.
