When you know the difference between the grades of lumber, you will be able to make decisions that may be more cost-effective for your building job than purchasing the wrong grade. Economy lumber may be sufficient for the job you are undertaking, and you will be wasting money by buying standard or construction grade lumber.
Choosing the Right Size of Wood
When you are unsure about the type and size of wood that you should purchase, you will benefit by taking professional advice to ensure that you request the exact type and size of economy lumber that is required to complete your job.
After logs are cut into boards, they are prepared as planks and then set to dry. Professional lumber companies will pass the wood through planning machines so that the wood is both cut and prepared so that it is available with a standard size for both width and thickness. Rough wood is available from some lumber yards, but the size will vary from one plank to the next. You may require hardwood lumber as rough wood when you are making furniture, and it will be up to you to plane and make the wood sizes to your own specific requirements.
Lumber is graded as construction, standard, utility and economy lumber. The higher quality of grade of wood will be more expensive than the next grade, which is why it is important to purchase the grade that is most suitable for the job that you are carrying out. The wood is also graded so that in the highest grade there will be no knots, down to the lowest grade where there may be a few knots and some defects in the wood.
Your lumberyard will be able to help you by explaining the different types of woods and grades available. They will also be able to show the difference between planed and rough wood so that you can decide whether economy lumber is perfect for your needs or whether you need to change your decision to the next grade for the type of woodworking project you have in mind.
