American Lumber Standards

The American Lumber Standards (ALS) are guidelines set to ensure that wood products meet consistent quality and size requirements across the industry. These standards specify dimensions, strength, and grading criteria for lumber used in construction, making sure it is reliable and safe. Managed by the American Lumber Standard Committee, the ALS helps both manufacturers and consumers trust that the lumber they purchase is uniform and suitable for intended purposes, promoting durability, safety, and efficiency in building projects.
