Hardwood Lumber grading involves an extensive series of steps to determine the best grade of wood. The process of grading is done by inspecting the wood's grain, size and shape. The grading guidelines are very complicated and take extensive study. A simple, condensed outline of the most common steps involved in grading a single piece of wood is as follows: Identify the species of wood. Identify the shape of the wood.

There are three species of hard wood, black, red and white. Each of these three species has its own characteristic hardness level and there is no "one size fits all" when it comes to choosing a hard wood. It is recommended that one use a mixture of different species in order to achieve the perfect grade of wood.
A wood's color is determined by the amount of melanin it contains. The darker the color, the more dense it is. The hardness level of the wood is determined by the amount of density it possesses. Larger hardwoods have greater density than small, lighter colored hardwoods.
The size of a wood's grain is what determines its hardness level. The higher the number of grains in a grain, the harder the wood. There are four major grades of hardwoods; a good grade of hardwoods has one, two, three and four grains. Grades can be determined by comparing the size of grain on each end with the size of the pieces being graded.
Grading is not an exact science. There are factors like humidity, temperature, exposure, humidity control and even age and type of wood to consider. The most common mistake made is assuming the material is completely dry before measuring it. The wood should be placed flat on a table, not upside down, to ensure uniformity in measurement. This is also true for sawing it. Some types of wood react differently to different types of saws, so it is best to test out a couple different methods to find out which one works best.
Once a complete list of qualities has been determined, a contractor will need to take a sample of each piece and perform the following analysis. to help determine what grade to use.
A qualified and experienced ipe clips grading contractor can advise a homeowner on how to properly grade their hardwoods.
Hardwood grades can range from A-1 to A-12 depending on how it was cut, the type of wood it is and its location. It is important to remember that different types of wood react differently to the same treatments and the same treatment cannot be applied to every type of wood. Therefore, it is advised that homeowners consult with a trained and experienced wood grading company to ensure proper application.
Wood grade determines the strength of the wood as well as the density, it possesses. It is essential that the grade be taken into account because it determines the amount of pressure that must be applied to get the wood to expand or contract. to its original size.
