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 pulley 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.
Special Poultry Curtain with multi layered & cross laminated UV stabilized polymer is also available.
Its unmatched strength apart , Silpaulin also offers the assurance of 100% waterproofing.Its heat sealed joints further guarantee that there is no leakage whatsoever.
It is all-weatherproof, with the ability to withstand tough climatic extremes.
It is specially UV treated to resist radiation, and is inert to most chemicals and acids.
Excellent tensile strength,tear and puncture resistance help Silpaulin withstand the impact of sharp edges and blunt objects. At the same time , its high elongation and flexibility enables it to be draped over odd shaped objects.
Available Colors in Curtain
For a shed size of 200 X 30, tow winches are required on each of the open side.
Four big pulleys (two on each side) are to be welded with the help of ‘J’ hooks at the two ends of the shed/chain link. And a small pulley is to be welded at every 10-12 feet on the top about 3 inches from the wall/chain-link.
The 5mm dia. Wire rope must be carried from the big pulley to the other end and must be tied to the curtain itself. With the help of ‘U’ clamp, connect the 3mm wire to the 5mm wire rope and tie the other end of the wire to the curtain.
