Fence also has posts, metal-roll pickets with right dihedral angles, gate and wicket provided with horizontal and inclined bars, as well as locking bolts and hoops for padlocks receiving. The pickets have dihedral angle cuts defining spikes at ends thereof. All horizontal fence components made of angle members are arranged so that upper angle member flanges are inclined at 45° to horizontal plane defined by rib of right dihedral angle of angle member. Upper edge of gate and wicket is over upper edge of frames adjacent thereto. The gate has one long leaf and one short one. The short leaf and the wicket are composite and include two parts so that upper and lower parts may be independently or simultaneously opened and closed.
