Instructions for installing gate cladding using 2-layer ASA-coated fluted wood-plastic panels.
When using 2-layer ASA-coated fluted wood-plastic panels for gate cladding, there are two main scenarios:
- Vertical gate cover, horizontal bar installation
- Horizontal gate cover, vertical crossbar installation.

Double-layered ASA-coated wood-plastic composite slats weigh 3,3kg/slat – 4,2kg/slat. When installing outdoor gate cladding, it is mandatory to install them on a frame structure with a spacing of ≤35cm between the frame slats. The frame slats are made of stainless steel or galvanized steel with dimensions ≥25x25mm and a thickness ≥1.2mm.
Weight of 3 fluted ASA wood-plastic panel codes at Kosmos Vietnam:
| Product code | Dimensions (mm) | Weight |
| 4S184X28 | 184 x 28 x 3000mm | 4,2kg/bar ± 5% |
| 5S169X14 | 169 x 14 x 3000mm | 3,3kg/bar ± 5% |
| 8S169X14 | 169 x 14 x 3000mm | 3,6kg/bar ± 5% |

ASA-coated, double-layered fluted wood-plastic composite panels are lightweight and versatile, suitable for large wall, ceiling, and gate cladding projects of various scales without area limitations.
Step 1: Prepare materials and tools for installing 2-layer ASA-coated fluted wood-plastic panels for the gate.
Supplies
Below are the materials you need to prepare when installing a 2-layer ASA-coated wave-shaped wood-plastic composite gate cladding:
- Skeleton bars (stainless steel, galvanized steel) size ≥25x25mm and thickness ≥1.2mm
- Iron bar
- ASA coated 2-layer wood plastic wave panels (4S184X28, 5S169X14, 8S169X14)
- Wooden bar with the same size as the bone bar
- Plate, L plate, L-shaped iron bracket
- Stainless steel anchors, flat-tailed screws (fish tail screws), iron anchors.
- Swing hinge, gate handle
- Copper nail
- Kosmos Multipurpose Glue.

Note about stainless steel shelf: The bracket is made from 304 stainless steel and has one slot for attaching to the groove of the ASA fluted panel and one circular hole for screwing the bracket to the support frame.

Tool
Here are 7 essential tools for installing ASA double-layer wave-shaped wood-plastic composite gate cladding:
- Angle grinder, drill, welder
- Tape measure, protractor, laser level, nail gun.

Step 2: Install the gate border
Use 1cm thick iron bars with a width of 5,3cm - 8,1cm (for 25x25mm 1,2mm thick bars). Use a welding machine to join the iron bars into a rectangle or square (depending on the gate size).
Width of the steel bar = size of the support beam + 2 x A (A is the thickness of the fluted ASA wood-plastic panel)
Kosmos ASA wave-shaped louvers are available in two thicknesses: 14mm (5S169X14 and 8S169X14) and 28mm (4S184X28).

Step 3: Install the gate frame
The gate frame installation process includes 3 stages:
Step 1. Right at the installation position of the last panel, weld a crossbar about 26mm from the gate edge to fix the wooden crossbar (or other types of wood used for outdoors) with the same size as the crossbar (size ≥25x25mm).
Step 2. Fix the wooden bar with the same size as the frame (25mm thick) to the frame just installed above by using stainless steel screws. Fixing this wooden bar has a special purpose: When constructing the final panel, instead of having to screw directly onto the panel surface (this will cause aesthetic loss due to exposed screws), we will fix the panel to the wooden frame with copper nails.
Kosmos recommends:
- Material for making bone bars: Stainless steel or galvanized steel with size ≥ 25x25mm and thickness ≥ 1,2mm.
- All welds should be smoothed and painted with anti-rust paint.
Step 3. Weld stainless steel or galvanized steel bars to the center of the iron bar, distance between bars ≤35cm.
- Horizontal: Bone bars ≤35cm longitudinally
- Vertical: The bone bars are ≤35cm horizontally.
Step 4: Build the skeleton into the gate
Before erecting the skeleton into the gate, it is necessary to install the pivot hinges into the bottom and top of the gate post.
Bottom of gate pillar
Fix the gusset plate to the floor with iron anchors and weld the swivel hinge to the gusset plate.
Top of gate post
- Fix the L-shaped bracket on the gate pillar with iron plugs
- Continue to weld the L-shaped bracket to the plate
- Finally weld the swivel hinge to the gusset plate.

After installing the two upper and lower swivel hinges, weld the frame to the hinge positions as shown in the image below. Leave a gap of 2-3 cm between the gate frame and the posts.
Step 5: Install the ASA wood-plastic composite fluted panels onto the gate frame (front of the gate).
ASA wood plastic corrugated panels at Kosmos Vietnam have 3 codes: 4S184X28, 5S169X14, 8S169X14 requirements when constructing ke.
1. Apply Kosmos multi-purpose glue to the bone bar.
2. Install the first panel:
a. Horizontal cladding: Install the ASA wood-plastic composite fluted panel with the male groove facing the ground horizontally and the female groove facing upwards (install the fluted panel from bottom to top).

b. Vertical cladding: Install the first fluted wood-plastic panel with the tongue and groove facing the wall vertically, with the tongue and groove facing outwards (install the fluted panel from left to right or right to left depending on the installer).

3. Attach ke Specifically designed for tongue and groove joints, pre-drill pilot holes and use stainless steel screws to fix the brackets to the support beams (the distance between the screw holes is equal to the distance between the support beams). ≤35cm).
4. Continue applying Kosmos multi-purpose adhesive to the frame to install the second panel.
5. Install the male groove of the second panel into the screwed negative groove of the first panel.
6. Attach the bracket to the groove of the second panel, drill pilot holes, and use stainless steel screws to secure the bracket to the support frame.
7. Repeat steps 4, 5 and 6 for each panel until almost the entire gate is covered.
8. Measure and cut the final panel to fit the frame.
9. Use a nail gun to secure the cladding panels to the mahogany frame with brass nails, ensuring the nail holes are spaced ≤ 1/2.10cm.
10. Install the handle on the gate, depending on the type of handle, choose the appropriate construction method.
** Kosmos recommends: Pre-drilling is required before screwing the screws into the grooves on the ASA wood-plastic composite panel.
Step 6: Install the ASA wood-plastic composite fluted panels onto the gate frame (the back of the gate).
On the back, just repeat the same 10 steps of step 5.
Double-layered ASA-coated wood-plastic composite slats (4S184X28, 5S169X14, 8S169X14) can be used not only for gate cladding but also for other purposes. Installation of ASA wood-plastic fluted panel for horizontal and vertical wall cladding. , and Ceiling panels for balconies and porches.
Besides gate cladding with 360-degree swivel hinges, customers can also opt for sliding gates or folding gates. The installation process for 2-layer ASA-coated fluted wood-plastic panels is the same; the only difference is the frame structure when installed onto the gate.
Note: Instructions are for reference only. To have the most suitable construction plan, it is necessary to survey the specific project and come up with an optimal construction solution.
