Concrete . I want to build a wall with 100 balustrades. What material is used to make the forms?

Question:The concrete balustrades will be 32 inch high. i will need a form that can be opened for removal and repeat mfg.

Answers:
you can use sheet plywood, build the form and then spray the form with a good release agent, or some type of silicone. It is common practice to spray with diesel fuel , but it is not so cheap anymore. have you thought of using some sort of pvc pipe, cut to length?
