Is the old wooden square easy to use? I want to ask.

First of all, there may be some problems in the quality of old wood squares, such as cracks and deformation. You have to find an expert to evaluate the grade and see if it meets the standard. Otherwise, the worst case is to affect the construction quality and bring trouble to the later acceptance.

In a word, quality is very important. If your wood square is used as a supporting template in structural construction, it is best to use new wood square. If it is only used for decoration, the problem is not big, but it is relatively difficult to deal with deformation.

Confirm that there is no problem, then you can calculate the engineering quantity, calculate the cost and compare the price of the new wood square.

Template, steel template, steel-wood composite template, etc. You can use it. Without drawings, you can't explain it without knowing the specific situation.
