Product description

Square tube can be roughly divided into black square rectangular hollow section and galvanized square rectangular hollow section, which are made of hot-rolled or cold-rolled strip steel or galvanized coil by cold bending and high-frequency welding. The shape and size are square or rectangular steel hollow sections. However, the only difference is that the hot-dip galvanized steel pipe is a square pipe made of black square rectangular hollow section through hot-dip galvanizing.


steel hollow section

It is mainly used in engineering buildings, building structures, glass curtain walls, doors and windows, tower cranes, bridge structures, steel structures, guardrails, machinery manufacturing, automobile manufacturing, home appliance manufacturing, shipbuilding, container manufacturing, factory buildings, power, agricultural buildings, agricultural greenhouses, bicycle racks, locomotive racks, shelves, fitness equipment, outdoor supplies, steel furniture, etc.
