Practical Notes

Strictly maintain timber moisture content within the specified 12-20% range to prevent warping, shrinkage, and fungal decay during transit.

Always stagger nails during assembly to avoid splitting the timber battens or planks.

Select the timber species class from IS 399 based on the payload weight and expected handling severity.
