细木工板（俗称大芯板、木工板）是具有实木板芯的胶合板，其竖向（以芯板材走向区分）抗弯压强度差，圣霖国际工字钢生产厂，但横向抗弯压强度较高。现在市场上大部分是实心、胶拼、双面砂光、五层的细木工板，尺寸规格为1220 mm×2440mm。

The woodworking board (commonly known as the big core board and woodworking board) is a plywood with solid wood core. Its vertical (core plate to differentiate) is poor in bending strength，圣霖国际工字钢厂家， but the transverse bending and bending strength is high. Most of the market is solid， plastic， double-sided sanding， five story blockboard，  1220 mm x 2440mm.

选择胶合板主要看其甲醛释放量和胶合强度。如果胶合板的胶合强度不好，容易散架。选择时注意胶合板的标称厚度与实际厚度是否相符。

The choice of plywood mainly depends on its formaldehyde emission and bonding strength. If the gluing strength of plywood is not good，圣霖国际工字钢， it is easy to fall apart. When choosing， pay attention to whether the nominal thickness of plywood is in line with the actual thickness.

工字钢的边长小，高度大，圣霖国际工字钢生产，只能承受单方向的力。  H型钢槽深，厚度大，可以承受两个方向的力。

工字钢只能用于横梁，而H型钢才能用于结构的承重柱。

The length of the I-steel is small and high. It can only bear the force of the single direction. The H steel groove is deep and thick， and can bear the force of two directi.

I-steel can only be used for crossbeams， and H steel can be used for structure bearing columns.
