Instructions for installing load-bearing plastic floors on mezzanine frames
Installing load-bearing plastic floors in high places such as mezzanines (lofts) must be done according to the correct techniques and recommendations of the manufacturer. This helps ensure safety when using and prolongs the life of the product. There are a total of 4 steps to install load-bearing floors, each step will have important notes/recommendations that cannot be ignored.

Step 1: Install the frame system with the distance between bars ≤400mm
To construct a load-bearing floor for a mezzanine (loft), we must install the frame system first. The material for making the frame is square iron bars, galvanized steel or stainless steel bars with a thickness of 1.4mm or more, with the following dimensions: 40x80mm, 50x100mm, 60x120mm.
Note on frame installation:
- The smaller the distance between the bars, the higher the load bearing capacity.
- Kosmos recommends a maximum distance of 400mm (40cm) between the bars. When welding galvanized iron frames, we must apply anti-rust paint to the welds to ensure durability.
- Grind the welds flat to ensure the skeleton is flat.

Step 2: Apply silicone glue to the frame and then install the floor bar on top.
Apply silicone glue directly onto the frame to install the load-bearing plastic floor bar. Apply as you go, avoid the glue drying out, reducing the adhesion of the floor bar.

Step 3: Shoot flat head screws and shoot silicone glue into the negative groove
We fix the negative groove of the load-bearing floor bar to the frame by flat head screw (Use screws 25mm or longer with flat heads so that the bars do not warp when assembled together). Then, add silicone glue to the negative groove along the length of the panel to limit water seepage into the groove and reduce noise when moving.


Step 4: Attach the next panel's male groove to the negative groove
We join the male groove to the female groove to cover the screw holes, creating a large, seamless, complete floor surface.

The connecting point of the two ends of the floor bar must be placed on the frame.
- In case of large bone bars, we put both ends in the center of the same bar.
- In case of small ribs, we have to install a double rib system.

In case of jointed floors, when installing the second row, we must install it staggered so that there is a difference between the two rows to increase the load-bearing capacity. We repeat the above operation until the floor surface is completely finished.

Frequently asked questions when installing load-bearing plastic floors
How much load can a mezzanine made of load-bearing floor withstand?
Mezzanine made of load-bearing floor can withstand a load of 500kg/m² with a beam distance of less than 400mm (40cm). The smaller the beam distance, the higher the load-bearing capacity.
Note to use:
To ensure safety, the floor should be able to withstand a load of <500kg/m². In areas requiring a load of >500kg/m², it is necessary to reinforce the frame system to increase the load-bearing capacity of the floor.
Why is the size of the load-bearing plastic floor 333mm wide?
With a width of 333mm, only 3 floor panels are needed for 1m of width, making it easy to calculate materials, limit material loss, and help save costs.
Can I use load-bearing plastic floor bars for ceilings and ceilings?
This product cannot be used for ceilings or ceilings because of its heavy weight. The load-bearing floor bars require a standard frame system and require high construction techniques.
Why must the connecting point of the two ends of the load-bearing floor bar be on the frame?
The connecting point of the two ends of the load-bearing floor bar must be on the frame to ensure the load-bearing capacity of the connection position.


Following the correct steps according to the instructions for installing a load-bearing plastic floor above will help us have a sturdy, safe mezzanine with a lifespan of 15-20 years.
