Testing Laboratory & Equipment

Kadant Carmanah maintains and operates a testing laboratory that conducts research and development and provides services to customers.
The lab can produce OSB strands using lab-scale stranding equipment to simulate strands produced from production machines. The laboratory is equipped with a 12/68 laboratory Disc strander, 12/48 laboratory Ring strander, a conditioning tank, drying chamber, screening equipment and measurement tools for strand quality.
