This is where hydraulic presses squeeze the layers or strands of Bamboo together to make a bamboo floor board. In a cold press the moisture content is hard to control as modern adhesives are water based and the best you can expect is 10% to 12% moisture within the finished floor.

The pressure exerted is more than 2000 tons on a cold press and up to 4000 tons on a hot press. When the bamboo boards come out of the balancing chamber we then cut the edges before processing.

The percentage of bamboo in our strand woven is 90% and percentage of glue is 10% with the density being 1.2g/cm3 which is much higher than other strand woven bamboo suppliers.

The hot pres not only exerts high pressure but also heats the boards through and with Bamboo we turn up the amount of heat to “carbonise” the boards at the same time. The hot press helps to melt and cure the adhesive into the grain structure of the bamboo to ensure a lifelong product that will not fail.

For all our Bamboo manufacturing we use the hot press. The following characteristics between hot presses and cold presses in bamboo flooring manufacture are shown below. The CHEAP Bamboo products use cold presses with staining of the Bamboo to get the different colours. In our high quality Bamboo we use the Hot Press method which also gives our Bamboo Flooring higher density and is also harder than most of our competitors

Density with the hot press
Using a higher force we get a much denser strand woven bamboo than our competitors

Cold press 0.97 – 1.07 g/cm3
Hot press 1.2g/cm3

Hardness this is where the hot press wins out.

Cold Press 2500 psi
Hot Press 2700 psi

The hot press method also ensures a more stable bamboo floor board that will not warp bend or twist

The cold press for Bamboo is limited to a width of 96mm due to the constraints on making sure the board is stable and the adhesive has done its job properly, this is why these boards are cheaper but will not last as long as our bamboo flooring and will possible warp during environmental changes.

In the cold press method you will see the lines in the finished product which is the adhesive showing as it was not melted and compressed into the grain of the Bamboo, this is very obvious in the vertical bamboo products and cheaper strand woven bamboo

The hot press method is also very green and environmentally friendly.

On our strand woven lacquered bamboo we apply 11 coats of the German Treffert Lacquer
