Universal Testing & Research Center (Division of Sustainable Stewardship Private Limited), an ISO 17025:2017 certified Laboratory approved by BIS, NABL and QAI.Sloping grain" in timber refers to the deviation of wood fibers from a perpendicular direction to the surface of the timber. It occurs when the fibers in the wood are not parallel to the axis of the piece, creating an angle or slope in the grain pattern.

• Effect on Strength:
  Sloping grain can weaken the timber, as it may compromise the fiber alignment that contributes to the material's strength. Timber with sloping grain may have reduced load-bearing capacity compared to timber with straight and parallel grain.
• Wood Splitting and Cracking:
  Sloping grain can make timber more prone to splitting and cracking, especially when subjected to changes in moisture content or mechanical stresses. The irregular grain pattern may lead to uneven responses to environmental conditions.
• Woodworking Challenges:
  Woodworkers and carpenters may face challenges when working with timber that has sloping grain. Cutting, planing, and shaping such wood can be more difficult, as the tools may encounter resistance due to the irregular fiber orientation.
• Warping and Distortion:
  Sloping grain can contribute to warping and distortion of the timber over time. Changes in moisture content or temperature may affect wood with sloping grain differently, leading to deformations in the material.
• Quality Grading:
  In the timber industry, the presence of sloping grain is considered a defect in terms of quality grading. Different grading standards may have specifications regarding the allowable amount of sloping grain in timber.
