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。
Thechoice of plywood mainly depends on its formaldehyde emission andbonding strength. If the gluing strength of plywood is not good， itis easy to fall apart. When choosing， pay attention to whether thenominal thickness of plywood is in line with the actualthickness.
弯曲度：工字钢高度小于或等于400MM时，每米弯曲度不得大于1.5MM，总弯曲度不得大于总长度的0.15%。高度大于400MM时，每米弯曲度不得大于1.0MM，型材厂家，总弯曲度不得大于总长度的0.1%。
Bending degree: when the height of the I-steel is less than orequal to 400MM， the bending degree of each meter must not be morethan 1.5MM， and the total bending degree should not be more than0.15% of the total length. When the height is greater than 400MM，the bending degree of each meter must not be more than1.0MM，圣霖型材购买， and the total bending degree should not be more than0.1% of the total length.
槽钢按形状又可分为4种：冷弯等边槽钢、冷弯不等边槽钢、冷弯内卷边槽钢、冷弯外卷边
依照钢结构的理论来说，型材，应该是槽钢翼板受力，就是说槽钢应该立着槽钢，普通槽钢规格而不是趴着。
According to the channel shape and can be divided into 4 kinds:cold bending e channels， cold-formed non echannel steel，圣霖型材， cold rolled steel， cold bending edge edge
According to the theory of steel structure， it should be theforce of the channel steel wing plate， that is to say the channelsteel should stand the channel steel， ordinary channel steelspecification rather than lie.
