Excellent bonding performance: The steel strip can be firmly connected with other parts of the pipeline (such as polyethylene matrix) to ensure the overall strength and tightness of the pipeline.

Good chemical stability: it can maintain stable performance in various environments and is not easily affected by chemical corrosion.

Enhanced anti-corrosion performance: By coating the adhesive resin, the anti-corrosion performance and anti-rust ability of the steel strip pipe are significantly improved.
