Wood keel of steel products including wood, steel thin-walled c-type form, strength and light weight. As a vertical flute using templates, direct contact with the template, the template immediately after the wall board installed directly by a certain distance vertically parallel rows can be opened. Play a supporting role skeleton template. Suitable for walls, columns, roof, instead of wooden. In the traditional construction process, the construction of the second template support system for wooden structure back shocked. First, it is because of their fixed-size products, not in accordance with a modular building design, building elevation varied, so the construction process to be truncated, the truncated process is bound to cause waste. And only the wooden cut shorter. Second, due to the traditional process is a combination of wooden and steel form, material strength of different sizes, because of deformation of the wooden mold problems run. Again, due to a process of wet concrete pouring operations, it will damp wooden deformed, with an increase in the frequency of use, the greater the deformation, resulting in the construction process, with the increase of the floor, the construction quality is getting worse problems
