“Building Block of Buildings”

Shuttering plywood, though invisible, has been contributing in no small measure, to the development of real estate in various measures. They have successfully withstood the test of efficiency for repeated applications in concrete columns and large construction. Our shuttering range is builder’s single choice. The plywood is preservative treated by vacuum pressure impregnation process with Copper Chrome Arsenic composition. ”Jai Assam” shuttering plywood can be repeated over and over again while making over precious construction.
Shuttering Plywood has the following Characteristic
  • Only selected hardwood veneers used, conforming to IS specification.
  • Phenol resin bonding of veneers is done
  • Total chemical insulation against termite and microorganisms by vacuum pressure impregnation treatment.
  • Offers sufficient flexibility for wood carving applications.
Film Faced Plywood: It is made with 170 GSM Phenolic polymer film on both sides to ensure a smooth surface for shuttering purpose that saves time and labour of plastering.

Technical Data:

Load and Deflection: By taking the maximum permitted deflection as 1: 270 (Via 1/270 of the span between the bearers) the following data gives the max. Load per Sq. Mts. a) When the face grain of the plywood is parallel to bearers:

Film Faced Shuttering plywood are used to all civil construction firms for casting concrete alabs; beams and boxes to obtain mirror finish surface output. No further plastering or finishing of surface are requirement if our film faced shuttering plywood is carefully used 20-25 repetitions can be obtain.
