Bamboo stairs for outdoor use

An outdoor staircase is not only an important structural part of a building, it must also be weatherproof. This is why well-known, traditional building materials, such as hardwood or steel, are often used. Bamboo is a beautiful, sustainable alternative with various advantages compared to other materials.

Bamboo offers several benefits compared to other materials when used as outdoor staircases:

Natural bamboo external stairs

Bamboo can be used in outdoor staircases, provided it has been produced in the right way. Without special treatment, bamboo has a very short outdoor life span, especially in humid climates. By treating the bamboo strips thermally and then compressing them, according to the Thermo-Density® process, the bamboo is suitable for outdoor applications. This bamboo material is processed into Bamboo X-treme® Decking or Beams which can then be used in stairs and, if desired, special anti-slip profiles can also be provided. Particularly in combination with terraces and wall finishes, the staircase can fit beautifully into the complete design.

The bamboo advantages

Bamboo as an outdoor staircase offers many advantages:

  • The natural appearance with a natural greying;
  • The high stability and hardness, with Class 1 durability (EN 350) tested following CEN/TS 15083-2 class (simulated graveyard test);
  • The fire resistant properties of the material reach fire class Bfl-s1 (EN 13501-1);
  • Bamboo is a very stable material: it hardly shrinks or swells and the steps, in a well-installed staircase, remain straight.

MOSO® has had its bamboo products tested in terms of the mechanical properties and, when needed, can provide the calculation values for structural applications in stairs and bridges.

Bamboo stairs as entrance to campus building

In the heart of the Brightlands Chemelot Campus in Geleen, Ector Hoogstad Architecten designed a real campus building. The large staircases invite you to enter the knowledge centre and the various catering establishments offer spacious terraces. No less than 1,600 m² of Bamboo X-treme® Decking boards and 2,500 m of Bamboo X-treme® Outdoor Beams were used to finish the terraces and stairs. MOSO partner Awood supplied the decking boards with an anti-slip profile.

"Sustainability and safety played a key role in the Center Court project. Bamboo X-treme® was selected because it is sustainable, low-maintenance and offers a long service life. In order to meet the high safety requirements, we installed the planks with an Urban Grid anti-slip profile."

Bamboo X-treme® Decking for outdoor staircases

For the production of outdoor staircases, bamboo is mainly used in the form of decking boards or beams. Bamboo X-treme® is the right material for this. More than 10 years after its introduction, the material has proven to be very durable and easy to maintain. The Thermo-Density® production process makes the boards more durable. Bamboo X-treme® greys naturally and is very stable, which results in boards that remain straight and flat. Among the technical properties of Bamboo X-treme®, the fire class Bfl-s1, use class 4 (EN 335) and durability class 1 (EN 350 tested according to CEN/TS 15083-2) are particularly appreciated.

Slip resistance of bamboo stairs

A frequently asked question about bamboo for outdoor staircases is whether the planks do not get slippery. Bamboo X-treme® has been tested using various methods and achieved the following test results three years after installation:

  • USRV 55 (dry – according to CEN/TS 15676)
  • USRV 29 (wet – according to CEN/TS 15676)
  • R 10 (dry – according to CEN/TS 16165 Annex B – DIN 51130)

If a higher slip resistance is desired or required, the steps can be fitted with an anti-slip profile. An example of this can be found on the stairs and terraces of the Center Court Brightland Chemelot Campus.
