Materials: Steel wire netting, common chain link fence (iron wire grid) and TECCO high tension chain link fence.

Construction: Steel wire netting and common chain link fence are fixed by the wire rope anchor or support rope. High- strength chain link fence is fixed with reinforcement wire, wire rope anchor, professional plate and with edge support rope if necessary.

Structure Configure:Steel wire netting, wire rope anchor, support rope, over sewed rope, chain link fence.

Features: It has high toughness and strength, easy to spread out. Through extensive field testing and comparison, it has the features of easy adapting to any slope terrain, installation standardization and systematization. System uses the cross cutting installation to short construction time and reduce the cost. System materials with special manufacturing process and high corrosion determine the long- time using. The protection fields can adequately protect the soil and rock stable, easy to artificial green and environmentally friendly.

SNS passive protection system:

SNS passive protection system consists of four main parts: steel wire rope, ring fence, fixed system (anchor, anchor rope, dock and support rope) vacuum ring and steel post. The steel post combines the steel wire rope as a whole with the protective surface to prevent the rock soil from falling off. It has the function of protecting the slope.

Materials: Steel wire rope, support rope, and vacuum ring.

Structure: Steel wire rope or ring mesh (with chain link fence for stopping the little rocks), fixed system (anchor, anchor rope, dock and support rope) vacuum ring and steel post.

Feature: When works as products withstanding huge impulse, it can avoid the damage may caused by the partial centralism stress, with the lengthened response time; increased mesh point surface; at the same time, it receives the partial stress with the whole. The SNS product is suitable for any complex terrain, while maintaining the primitive landform. SNS product has mesh opening allowing good vision, convenient for planting trees and grasses and good for the environmental protection. It is simple for installation to save time.
