According to the material, the pull rods produced by Lichuang Luggage Fittings Factory can be divided into iron pipe pull rod, aluminum pipe pull rod, outer iron and inner iron aluminum pull rod. Among them, all-aluminium material is lighter, stronger, harder to deform, higher cost, so the factory price is also higher. The luggage with this kind of tie rod is generally not cheap, so it is more used in high-grade luggage. Our tie rod is commonly known as box-packed iron pipe, box-packed welded pipe, and tie rod iron pipe. Welcome to consult and place an order enthusiastically.
