A unique adjustable guttering anti-warping anti-sagging safety-truss gate comprises corner gutters to drain rain water, body gutters to drain rain water, extension tubes having multiple built-in tunnel systems to drain rain water, struts having multiple built-in tunnel systems to drain rain water, and vertical tubes having multiple built-in draining-hole systems to drain rain water down to the ground. Further, the unique gate comprises multiple ridge systems built into the extension tubes to strengthen the unique gate, and multiple spring systems built into the vertical tubes to strengthen the unique gate and to absorb impact forces, warping forces, twisting forces, and sagging forces exerted on the unique gate during its lifespan. The corner gutters, body gutters, and vertical tubes are welded to one another to create the frame of the unique gate. The extension tubes are inserted into the body gutters, and the struts are screwed in the corner gutters and on the extension tubes to define the width of the unique gate.
