#1 Grade
Materials are saw kerfed to provide a stress relief as the product is drying. This allows the log to dry faster and controls warping and the appearance of large checks in the finished product. This product is of the highest standard for facial integrity and structural strength. It also carries technology to be the most stable, with the greatest longevity. Wall logs are kiln dried or air dried to a moisture range of 20%. Rafters may be of a higher moisture content.

#2 Grade
Materials are of a high average industry grade. The logs are generally cut from dead standing trees that are harvested within a year or two after they die. This allows the tree to dry to a moisture level of 15% to 23%. #2 logs usually have very little warp because drying takes place while the tree is still standing. Check sizes are larger than that of the #1 Grade, since the stress has already been released. #2 Grade wall logs and rafters are sound and second only to the #1 Grade in structural strength and facial beauty.

#3 Grade
Materials are generally milled from dead wood that has seasoned for some time. Larger checks are allowed, as well as larger knots. The product is widely used in the industry for wall logs, but is not recommended for high snow load structural rafters. The product works well in dry climates, but does not have longevity to withstand wet climates. M-30 rustic wall logs are rough sawn. Some dry rot, bug holes and spiral checks may be in the product. Some bark and planer skips may be visible. End trim cuts and lumber wrap are extra.

Green Logs
Materials are considered to have a moisture level over 30% and may contain pitch. This product may be used for rafters or beams, where settling is not a large concern. When green product is used for wall logs, adjustments need to be made in construction to deal with settling. Prices for green logs are bid on a daily basis.
