As in rûne stielen ketting ketting fabrikant foar 30 jier, ús fabryk is ferbliuw mei en tsjinne de tige wichtige perioade fan Sineeske keten meitsjen yndustry evolúsje catering foar mynbou (koalmyn yn it bysûnder), swiere lifting, en yndustriële conveying easken op hege sterkte round stielen link keatlingen.Wy stopje net by it wêzen fan 'e liedende fabrikant fan rûne kettingketen yn Sina (mei jierlikse oanbod fan mear as 10,000T), mar hâlde ús oan net-stopjende skepping en ynnovaasje.
