Product Content Description:

1. Description
Pneumatic inflatable rubber mandrel is usually called culvert rubber balloon. It is a kind of cylinder bag that can expand, shrink, used to form concrete component of cavity. It is easy to be used, convenient and durable, is soft and can fold, curly, contraction when it is deflate, it have the enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional template, it is used in reinforced concrete members, including stake roof, roof board column, beam, building, water conservancy project(shipyards slipway, dock) .
