Of course, lengths are customized for each job. A wide range of depths are available, far too many to list here, so please contact your local manufacturer for more information on their offerings - in general depths start at 6" and go up to 30" and beyond. Standard widths are specified in the above publication, but can be customized as needed. The following table comes from the American Institute of Timber Construction's Standard Specification for Structural Glued Laminated Timber of Hardwood Species publication.ĪNSI/AITC A190.1-1992 allows for any width and depth of glue laminated timber. It is advisable to check with your contractor or lumber supplier before finalizing design details so you aren't surprised by what you receive. Square on all four sides makes this board ideal. Combine with other moulding to create a unique build-up pattern. Natural characteristics like color variation in each board. However, in some cases, like the big-box hardware stores, the boards come in dimensional widths similar to softwood widths. Stain grade poplar, ready for light sanding and stain of choice. In most cases, hardwood boards come in random widths to be ripped to size by the woodworker. For instance, hardwood trim that ends up being just over 1" thick (surfaced on 2 sides) is called a five-quarter (5/4) board. In North America, hardwood lumber is usually specified using the quarter system, where a board is identified by its thickness in quarters of an inch. Surfaced refers to a finishing process that smooths the lumber to remove all saw marks. Hardwood lumber is sized based on how many sides are surfaced. Softwood lumber comes in a number of standard lengths as listed in the table below. North American Standard 8-by Lumber NOMINAL SIZE (INCHES) North American Standard 6-by Lumber NOMINAL SIZE (INCHES) North American Standard 4-by Lumber NOMINAL SIZE (INCHES) Below is a chart that has the common sizes of framing members and their actual sizes in imperial measure, and in metric sizes. North American Standard 2-by Lumber NOMINAL SIZE (INCHES) North American Standard 1-by Lumber NOMINAL SIZE (INCHES) In the United States, softwood lumber is governed by the National Institute of Standards American Softwood Lumber Standard (PS 20).

Please visit our How To page for advice on tarpaulin usage.Softwood lumber is generally used for framing walls and floors. For example if you are looking to cover a roof for an extended time period, it will be worth opting for something of a heavier duty than a standard economy sheet under the same conditions, a heavy duty sheet is likely to last much longer. When choosing a tarpaulin, the application it is going to be put to should be considered, as well as the weather conditions it is to be used in. We do not offer a guarantee to the lifespan of any of our products because of the huge variety of applications they can be put to however as a general rule, the heavier the grade of tarpaulin, the more durable it can be expected to be. In terms of the grades of tarpaulins we can supply, our range is from 80gsm up to 560gsm. Our tarps are measured in GSM (Grams per Square Metre), which relates to the weight of the material a tarpaulin is manufactured from.
With the exception of the Canvas tarps, all of our tarpaulins are cut metrically (in metres), and so the imperial dimensions (in feet) are approximations only. Some of our ranges are produced to finished size, where any tolerance will be nominal.
Indeed, if you are working to particularly tight dimensions then it is worth opting for a larger size. It is therefore important to allow for such a possible shortfall. As a result, the finished size of a tarpaulin can be up to 30cms shorter. Therefore, if you are going to be using a tarp to cover a three dimensional object, all dimensions must be measured and totalled to determine the size of tarp you need.īefore you buy your tarpaulin, it is also important to remember that unless specifically stated as a finished size, the sizes stated refer to the cut size of the sheet this is the industry-standard terminology to indicate the size of the fabric before it is seamed, hemmed and eyeleted. Know you need a cover, but not sure what size?Ī tarpaulin is a two dimensional product (length x width).
