Instructions for installing concealed 1-layer wood-plastic horizontal slats

Step 1: Prepare construction materials and tools
Supplies
Below are 6 types of materials you need to prepare:
- Stainless steel or galvanized steel bar
- Wood plastic slats (LAM35X35, LAM50X50, LAM60X40, LAM80X40, L105X50, LAM160X80)
- Iron bracket
- Stainless steel screw with pee tail
- Code
- Iron anchor.

Tool
6 necessary tools for the construction process of sunshade horizontal slats include:
- Welding machine, angle cutting machine, drilling machine, laser machine
- Tape measure, protractor.

Step 2: Measure, cut and thread the stainless steel or galvanized steel bar into the wood plastic slats
| Wood plastic code | Corresponding size of galvanized square iron bar with slat core threaded through |
| LAM35X35 | 20 x 20mm |
| LAM50X50 | 35 x 35mm |
| LAM60X40 | 25 x 25mm or 20 x 40mm |
| LAM80X40 | 25 x 50mm |
| L105X50 | 30 x 30mm |
| LAM160X80 | 50 x 100mm |
B3: Build the skeleton
Column section
- Welding stainless steel or galvanized steel bars with brackets
- Fix the bracket to the concrete floor with 12mm iron anchors for security.
The 3 popular types of codes today include code 160, code 120, code 100.
Roof
- Weld 4 tie bars to the column
- Weld 2 crossbeams to form 4 cells with each cell length or width ≤ 1,5m.

Step 4: Install 1 layer wood plastic slats on the roof
- Fix the slat with its inner galvanized steel or stainless steel core with an iron bracket by stainless steel screws.
- Fix the slats to the tie beams and cross beams through the iron brackets.

Kosmos recommends a distance of 5mm between the ends of the slats when in contact with the tie beam or cross beam.
To build a roof longer than 1,5m, it is necessary to use horizontal beams as support for the slats. Absolutely do not connect the slats directly together.
Wood plastic slats expand from 5 - 10%, below is the expansion table of wood plastic slats according to the weather:
| Season | Distance between the slat and the tie bar | Elongation of the slat Morning/evening (sunny) | Elongation of the slat Afternoon (sunny) |
| Spring/Winter | 5 - 8mm | 7 - 8mm | 5 - 6mm |
| Summer/Fall | 3 - 5mm | 4 - 5mm | 3 - 4mm |
Depending on the weather of the installation area, customers should refer to the expansion table to leave appropriate gaps.
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 to make recessed sunshade slats, outdoor wood plastic slats are also used to make sunshade slats. surface mounted, tilt mount or construction of facade panels, decoration of building facades.
