The new material has undergone a series of composite formulations and successfully passed the lSO 877-2:2016 1 Year Environmental Aging Test required under the respective ladder standards as a wood replacement;
Meets lSO5489:2008 and lSO 799-1:2019 standards;
At least 20% lighter in weight as compared to 1.4kg wood steps for easier handling& deployment;
Able to sustain 1100kg loading with a minimal residual deflection after the load is released;
Drainage system of the step reduces wind resistance and water retention providing better stability performance over traditional wood;
Consistent quality can be achieved compared to fluctuating natural wood quality due to various sources in the supply chain;
More predictable and scalable global supply with economic benefits as wood harvesting is government regulated and requires time to harvest;
The material of the step can be recyclable for reuse.
