In a poultry house, curtains are used to protect
the birds from direct sunlight, rain and the
harsh winter conditions. The curtain helps to
maintain the inside temperature during brooding
period. Dhumals curtains are made from a special
HDPE woven faric consisting of five layers with
the fabric laminated on both the sides. The
material is UV stabilized to avoid the harmful
effect of the UV rays. The five layers are
joined using a special type of electronic
welding process to give a 100 percent water
proof joint. Curtains are reinforced with Nylon
ropes on all four sides to optimize quality and
eyelets
Dhumal Industries has introduced the curtain
winching system to assist the labourer to raise
or lower the curtain with ease and simplicity.
Dhumals winches are made from the best
quality steel and are powder coated to prevent
the winches from rusting. The winches are also
provided with a unique locking so that the
curtains can be winched to the desired height
without a reverse fall back. The other
accessories required are the small pully made
from stainless steel and bit bulleys which are
made from M.S. with nickel coating on which the
3 mm dia. And 5 mm dia. wire rope run
respectively. With the help of 'J' hooks, both
the pulleys are fitted. A 25 mm dia. M.S. Pipe
runs through the length of the curtain. One
winch can raise or lower a curtain around 200
feet in length.
