北美木材尺寸以1/4”英寸为最小的测量单位和进位单位。1”英寸厚度的板材被写成4/4，以此类推。北美木材标准厚度为：3/4，4/4，5/4，6/4，8/4，10/4，12/4等。木材厚度尺寸的美制和公制还算如下图。 1英寸(inch)= 25.4毫米( mm) 1毫米(mm)= 0.0394英寸(inch) 1英尺(feet)= 12 英寸(inch)
4/4,5/4,6/4,8/4 These are units of measure for the thickness of unsurfaced lumber (rough). 没有打磨以前板材厚度尺寸。 Board Foot (bf) This is a unit of measure one foot long, one foot wide, and one inch thick or its equivalent. In surfaced lumber, the board foot is taken from the lumber before surfacing. 板尺：是北美板材的体积单位。相当于1英尺长，1英尺宽，1英寸厚的板材的体积。打磨好的板材体积按打磨以前的体积计算。1MBF(千板尺) 是1000个Board Foot (板尺)的意思。通常情况下，对板材来讲：1MBF= 2.36 M3, 即1千板尺= 2.36立方米。 Kiln Dried Lumber This is the process of taking moisture out of boards, the process of which affects stability. Kiln dried lumber is nominal 7% to 9% moisture content. 窑干型板材，含水量在7%-9%之间。 Green Lumber This is the lumber before the removal of moisture. 新鲜板材，即没有做干燥处理的板材。 Random Widths and Lengths(RW，RL) This refers to the variation in widths, always measured in inches, and in lengths, always measured in feet. When a minimum width and length is ordered all lumber shipped will be minimum or wider, minimum or longer. 满足美国硬木协会要求的板材等级尺寸条件下的自然宽(RW)，和自然长(RL)板材。 Rough This is unsurfaced lumber. 没有作磨光处理的板材。 S2S This is lumber that is planed or surfaced on two sides. 2面干净板材，即将板材前，后两面磨光处理。 S4S This is lumber that is planed or surfaced on four sides. 4面干净板材，即将板材前，后和左，右四面磨光处理。 FAS/ Selected Sizes These are lengths or widths that are specifically requested. (Example: 6" wide boards or 6' long boards.) 符合美国硬木协会要求的板材等级：特级 (一般宽6”英寸以上，长6英尺以上) 1 Comm 1 Common Grade of Lumber - Grades at least 66.66% clear in cuttings 3" wide by 3' long or 4" wide by 4' long minimum. Minimum 3" wide by 4' |
