C. ENDLOCKS
The end locks are made of cast malleable metal or galvanized steel, spot-welded to both ends of alternate slats, designed to prevent lateral movement of the slats and allow for a smooth operation of the shutter.

E. BOTTOM BAR

The bottom bar is constructed from two right angled GALVALUME steel bars, each not less than 38mm x 38mm x 2.5mm thick. Between the two right angled GALVALUME steel bars is sandwiched the bottom slat of the curtain, which is securely welded into position. METROshutters™ bottom bar is designed to place the padlock holder, weather stripping and/or safety device.

G. GUIDES

METROshutters™ guides are formed using GALVALUME steel channels with sufficient depth to retain the curtain in place under the horizontal pressure; it also prevents ends of curtain from de-aligning from guide slots. Top sections shall flare for smooth entry of curtains. Stops shall be provided to limit the curtains from moving beyond the guides. METROshutters™ guides are featured with Polyvinyl Chloride strip to act as a wear strip and to prevent steel to steel contact with the curtain and guide allowing for longevity and quiet operation

I. HOODS

The drum is made from m/s tube of proper thickness and diameter corresponding to the size of the curtain and then is capped at both ends. The wall thickness is designed sufficiently to limit deflection. Within the barrel, an oil-tempered, helical, counter balancing steel spring, shall be installed which is capable of producing sufficient torque to assure easy operation of the door.
