镀锌构件的锌层应与基底金属连系安稳，经捶击试验镀锌层不剥离、不凸起，并合适《高速公路波形梁钢护栏》（JT/T281-1995）附录C的划定。(10)componentgalvanizedzinclayershouldbeuniformsamplebyetchingofthecoppersulphatesolution,5timesthesamered,andinaccordancewiththeprovisionsofthehighwayguardrail,JT/T281-1995AppendixB;componentgalvanizedzinclayershouldbeandbasemetalisfirmlycombinedbyhammeringtestgalvanizedlayernotpeeling,notraised,andinaccordancewiththeprovisionsofthehighwayguardrail,JT/T281-1995AppendixC.The（11）镀铝构件的铝层应平均。
波形梁护栏是一种公路中央分隔带开口处用组合型波形板活动式钢护栏，该护栏由两片波形钢护栏板及两者之间固定夹放的两根立柱构成，两根立柱固定夹装在两片波形钢护栏板之间。在公路正常营运时，该护栏利用插拔立柱可方便地插入开口处预先设置的插拔孔内，起到隔离和防护作用，同时与公路外边上的护栏带相呼应，整齐划一，美观配套。车辆对其碰撞时，由于波形钢护栏板有良好的耐撞性
