Instructions for installing double-layer polymer-coated wood-plastic composite slats for fencing.

Double-layered polymer-coated wood-plastic composite slats (box slats) are commonly used for fences, sunshades, pergolas, signage, and curtain walls, with a lifespan of 15-20 years. Kosmos guarantees quality for 3 years.

When constructing a fence using polymer wood-plastic composite panels, keep these four points in mind:

1. Insert the stainless steel bar or galvanized steel bar into the slat.
2. Lam box construction on the frame with distance between bars ≤100cm (≤1m)
   
3. The slats and the ribs are connected together through the L-shaped iron bracket by stainless steel screws.
   
4. When it is necessary to connect the slats, The distance between 2 connecting bars is from 3 - 5mm..

Step 1: Prepare materials and tools for installing polymer wood-plastic slat fence panels.

Supplies

Below are 9 types of materials you need to prepare:

1. Stainless steel or galvanized steel bar
2. Kosmos 2-layer polymer-coated wood-plastic composite slats (LAM60X42, LAM100X50)
3. Kosmos Polymer End Caps (NL60X42, NL100X50)
4. Code
5. Iron plate L
6. Iron anchor
7. Stainless steel screw with pee tail
8. Plastic end caps for metal box sections.
9. Kosmos exterior glue.

Note on how to use iron bracket L: The L-shaped bracket measures 50x30mm, is made from 304 stainless steel, and has two round holes and two elliptical holes in one bracket.

• Round hole: Fix the L-shaped iron bracket to the wall or to the stainless steel or galvanized steel bar.
• Elliptical bore: Use stainless steel screws to fix the L-shaped iron bracket onto the slat.

Refer to the image below for screw positions for the iron bracket. In addition, any direction of the iron bracket (long, short) when placed on the wall/frame or slat is fine.

Note: Before screwing the L-shaped bracket onto the slat, you need to insert the iron core into the slat first.

Tool

The following 6 tools are essential for the installation of wood-plastic composite slat fences:

1. Angle grinder, drill, welder
2. Laser pointer, tape measure, protractor.

Step 2: Measure, cut and thread the stainless steel bar or galvanized square steel bar into the wood plastic slats

When inserting the iron core into the slat, a gap should be left. 2cm at each end of the bar To ensure there is enough space to install the end cap properly and aesthetically.

Step 3: Cover the end of the slat with a plastic slat end cap

Cover the slat end with plastic slat end cap using Kosmos exterior glue.

Step 4: Erect the fence frame.

The process of constructing the fence frame consists of the following two steps:

1. Secure the base plates to the concrete foundation/foundation beam using steel anchors (distance between base plates ≤2m).

2. Weld the stainless steel (or galvanized steel) column securely onto the base plate.

3. Cover the ends of the stainless steel (or galvanized steel) posts with plastic caps.

4. Weld horizontal stainless steel or galvanized steel bars spaced ≤1m apart onto the stainless steel posts.

Step 5: Install 2-layer polymer-coated wood plastic slats

The process of installing polymer wood-plastic slats onto the frame consists of 3 steps:

1. Measure and mark the positions where the L-shaped brackets will be installed on the frame (the distance depends on the user's needs). Then, pre-drill pilot holes and use 304 stainless steel screws to fix the L-shaped brackets to the frame. The brackets are installed horizontally.

2. Secure the first L-shaped bracket to the support beam (insert stainless steel screws into the round holes of the L-shaped bracket).

3. Install the box louver into the position of the L-shaped bracket already fixed above. The louver is secured by the L-shaped bracket at the elliptical hole with 304 stainless steel screws as shown in the image.

4. Do the same for the remaining slats until the end of the project.

Continue using stainless steel screws to secure the L-shaped iron bracket to the frame.

After installing one row of metal brackets, one box-section louver will be secured.

Every 3-6 months, the project needs to be checked and periodically maintained to ensure the best lifespan of the project. If any abnormalities are detected in screws or slats, the construction unit must be notified immediately.

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.

In addition to being used for fencing, double-layered polymer-coated outdoor wood-plastic composite slats are also used for... decorative wall cladding, sunshade.
