Aohong \u00e8 un produttore professionale di cuscinetti in gomma laminata, che offre cuscinetti in gomma di alta qualit\u00e0 progettati per prestazioni affidabili in ponti, edifici e applicazioni strutturali. Questi cuscinetti sono costituiti da strati multipli di gomma naturale o neoprene rinforzati con piastre d'acciaio, legati attraverso la vulcanizzazione, che forniscono un'eccellente rigidit\u00e0 verticale per trasferire i carichi e un'eccezionale flessibilit\u00e0 orizzontale per assorbire gli spostamenti e le rotazioni. I cuscinetti in gomma riducono efficacemente le vibrazioni e l'impatto del carico dinamico, migliorando la stabilit\u00e0 strutturale e la durata. Grazie alla forte resistenza alla corrosione, all'elevata durata e alla manutenzione minima, sono ampiamente utilizzati in ponti autostradali, ponti ferroviari, solette prefabbricate in calcestruzzo, strutture in acciaio e costruzioni di stadi.
