General: How to handle and store your Wesbeam Laminated Veneer Lumber products.

  1. Wesbeam Laminated Veneer Lumber should be stored well clear of the ground on level bearers spaced at maximum 1800mm centres
  2. It should be covered to keep dry but still allowing for ventilation
  3. Avoid placing LVL over areas susceptible to ponding.
