In July 2010, contruction began on the Ruby Pipeline, a 678 mile natural gas pipeline stretching from Opal, Wyoming to Malin, Oregon. From the time contruction began until it was officially placed in service one year later, a significant amount of oak and other hardwood timbers were used for crane mats and other functions in support of the construction activity.
|Species||Oak (May be mixed Red and White or all Red or all White Oak). Typically heavy to Red Oak.|
|Source||Resawn from timbers reclaimed from crane mats used on the Ruby Pipeline, a 678 mile long natural gas pipeline running from near Opal, Wyoming to near Malin, Oregon.|
|HC/FOHC||Generally Heart Center (HC)|
|Metal||The bolts that held the mats together are removed to enable the material to be resawn. Other metal is uncommon. The result is that these timbers are generally metal-free, although Trestlewood does not guarantee that there is never any metal left in or broken off inside a timber.|
|Holes||Frequent holes exist where bolts have been removed. 18' mats were generally assembled with 4 or 5 bolts, resulting in holes that are often 4 to 5 feet apart. Holes can vary in size somewhat; many are about 1.5" in diameter. Other holes are much less common but allowed. Staining around bolt and other holes is allowed.|
|Checking/Cracks||These timbers generally have checking from the heart center to the exterior faces of the timber. Some of this checking may be extensive. Checking is out of specification only if it renders the timber unsound (meaning that it may fall apart because of the check.) In addition, timbers can have surface checking and cracks, moderate butt checking and end splitting.|
|Moisture Content/Stability||Moisture content varies from beam to beam, but can be quite high. These timbers (and lumber cut from these timbers) are generally less stable (and more prone to shrinkage, twist and other movement) than timbers resawn from Oak and other hardwood timbers reclaimed from barns and other structures. The moisture content of a specific beam depends on such factors as the amount of air dry time the beam has had.|
RubyOak Resawn Timbers (including mantels, both finished and unfinished) are a rustic product that can generally be expected to become more rustic (shrinkage, twist and other movement; additional checking; etc) over time.
|Surfacing||Original mat timbers were rough-sawn (many timbers were circle-sawn and some were band-sawn.) Trestlewood disassembles the mats and uses its circular sawmill to cut the largest solid timber that it can from each mat timber. Where faces are in good condition, Trestlewood will generally leave them. This results in many of the resawn timbers having faces with different amounts of weathering (and sometimes a combination of circle-sawn and band-sawn surfacing.) |
Where a uniformly fresh-sawn look is desired, Trestlewood can resaw timber faces to provide the same. Default resawn surfacing is circle-sawn. Band-sawn and planed (S4S) surfacing options are often available.
|Standard Dimensions||Common cross sections include 6x6, 6x8 and 6x10, with lesser quantites of 6x12 and 8x8 - 8x12. Dimensions can be up to 3/4" nominal. Lengths are generally available to 18', with some longer pieces also available.|
|Weight||Typically, approximately 4 pounds per board foot|
