At present, the fences on the market are classified according to materials, mainly divided into mesh guardrails, cast iron guardrails, aluminum alloy guardrails and stainless steel guardrails.
Cast iron guardrail: low corrosion resistance, serious corrosion; poor impact resistance, brittle and easy to break, insufficient strength; excessive spacing or height, easy to climb and drill, poor safety; serious environmental pollution during production, high maintenance costs, rust removal Anti-rust paint causes secondary environmental pollution and harm to human body.
Stainless steel guardrail: The sun shines into light pollution such as reflection and glare. In winter, it gives people a feeling of coldness. The wall thickness is too thin, the strength is not enough, and it is easy to bend and deform.
Aluminum alloy guardrail: It adopts full-assembly design, quick and easy installation; rich color to meet the individual needs of different customers for guardrail; good weather resistance, salt spray resistance and damp heat resistance, suitable for different regions; The painted surface makes the guardrail have a good self-cleaning performance, and the rain wash and water spray can be as clean as new.
