免熏蒸木方（lvl层积材）与实木锯材比较，具有的优点：
      1、可将原木的疤节、裂痕等缺陷分散、错开，根据试验测试，强度、韧性比实木提高了3倍，使其质量稳定，强度均匀、材料变异性小，是替代实木最理想的结构材；
      2、尺寸任意调整，不受原木形状和缺陷的影响，最长9.6米，最宽1.6米，最厚30厘米，可根据客户要求定做，任意选择尺寸，利用率高达100%；
      3、加工和木材一样，可锯切、刨切、凿眼、开榫、钉钉等
      4、具有防虫、防腐、防火、防水等性能，主要是在制作过程中进行了相应的预处理或采用了特殊的胶粘剂；
      5、具有极强的抗震性能和减震性能以及能抵抗周期性作用力产生的疲劳破坏；
      6、绿色环保、无污染，在制作过程中使用优质的环保胶粘剂，甲醛释放量不仅达到国家标准，而且可以达到欧美发达国家标准，能确保您的身体健康
 
  LVL(Laminated Veer Lumber)
Laminted Veer Lumber is an engaged wood product that uses multiple layers of thin wood assembled with adhesives .
  It offers several advantages over typical milled lumber;it is stronger ,straighter,and more uniform.
  It is much less likely than conventional lumber tu warp ,twist ,bow,or shrink due tu its composite nature.
  Made in a factory under controlled specifications,LVL products allow users tu reduce the onsite labor .
  They are typically used for header ,beams,rimboard ane edge –forming material .
  It is siminlar in appearance to plywood without crossbands.It is typically rated by the manafacture for elastic moduli are 1.8,1.9
and 2.0 million psi and common allowable
