Hollow plastic formwork channel type is a solution which allows to facilitate the design of the object, retaining all its strength characteristics, while significantly saving time and money for the construction of facilities in the monolithic construction of buildings. Used worldwide for construction of shopping, entertainment and sports centers, factories, logistics warehouses and factories, office and business centers, municipal purposes. A variety of available sizes allows to implement any engineering and design projects to life.
Advantages:
Example of savings calculation concrete mix:
The volume of concrete used on the m3, is calculated as follows:
In this example, assume that we use a form of D3 in the center panels of the ceiling.
The maximum recommended height of the potting mix over form is 175 mm.

Diaphragm
The diaphragm must be used with the forms of D3 and D4 to exclude abnormalities. Two in each block In (as pictured) and one in the center of each block.
Assembling blocks
Forms are available in six types (in depth) and two types. Use B to adjust the length of the form. In the right part of the diagram shows how the installed units And to change the length of the form in large range.
The table below shows the ranges at which the length can vary forms depending on the number of used blocks A and B.
