The invention discloses an improvement method for a suspension clamp and an energy-saving and abrasion-reduction suspension clamp. The improvement method comprises the following steps of: 1) grooving the bottom end of a boat body of the suspension clamp; 2) carrying out sand blasting on the grooved boat body, a press plate and a hang plate to lead the surface roughness of the boat body, the press plate and the hang plate to be (Ra5.0-10.0) millimeters; 3) spraying the sand-blasted boat body, the press plate and the hang plate to fabricate an aluminum coating, wherein the thickness of the aluminum coating is 0.5 to 1 millimeter; 4) carrying out oil removal and rust removal on an U-shaped bolt and a socket, and then fabricating an aluminum coating under the effect of a plating assistant agent by using a hot dipping method, wherein the thickness of the aluminum coating is 200 to 500 micrometers; 5) fabricating an inner lining of the hang plate, leading the inner lining to be interference fit and embedding into the hang plate; and 6) assembling all parts of the suspension clamp. With the improved suspension clamp disclosed by the invention, since the thermally-sprayed aluminum coating and the hot-dipped aluminum coating have better atmosphere corrosion resistant performance than a hot-dipped zinc coating, the effects of energy saving and abrasion reduction can be achieved, and the corrosion resistant performance also can be improved.
