High Quality Galvanized Steel Plate - Galvanized rectangular pipe hollow section steel pipe – Lu

Introduction

Galvanized square pipe is a hollow square section steel pipe with a square section shape and size made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil as a blank, cold-bent and formed by high-frequency welding. , Or a galvanized rectangular tube made of cold-formed hollow steel pipe prepared in advance and then processed by hot-dip galvanizing. Galvanized square pipes are divided into hot-dip galvanized square pipes and cold-galvanized square pipes from the production process. It is precisely because the processing of these two galvanized square tubes is different that they have many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties.
