GLOBE SHUTTERING PLYWOOD - IS 4990 : 1993
Globe
Concrete Shuttering Plywood is manufactured from veneers
of well selected and strong hardwoods. It is bonded
with high quality liquid phenol formaldehyde synthetic
resin manufactured at our resin plant, pressed with
thermal setting hot press and treated with special
quality preservatives. This unique process makes it
ideally suitable for use in concrete shuttering and
frame work by Architects, Civil Contractors and other
Quality and Cost Conscious Professionals. Globe Concrete
Shuttering is having strong load bearing capacity
which prevents swelling during shuttering works. It
confirm to IS - 4990 - 1993. Globe Shuttering Plywood
offers high re-usable value under careful and proper
handling.

Permissible
Spans: To access and calculate the maximum permissible
span without causing undue deflection. The following
data is recommended per sq. mtr. i.e. 1:270 viz. (1/270
of the span between the bearers if wet boards are
used, the maximum load must be reduced to 75%)
