SERVING CUSTOMERS THROUGH TUBE MAKING

INTRODUCTION

Maruichi Steel Tube Ltd. and its group companies (MARUICHI Group) are a world leader in the welded tube industry, having been offering customers dedicated services through tube making since their estab-lishment in Japan in 1947.MARUICHI Group in Japan have been engaged only in tube making, amassing technological knowhow and expertise in that chosen field and having lined up scores of specialized state of the art tube mills as well as cold reduction and continuous hot dip galvanizing lines, which enable them to accommodate their customers needs for a wide range of round (from 8mm to 508mm), and similar size square and rectangu-lar tube (up to 400mmX400mmX19mm). With their production in Japan running around 1,500,000 metric tons per year in various product lines and sizes, they can be considered one of the very few general tube manufacturers in the world. Through the 15 strategically located manu-facturing facilities in each regional market of Japan and 20 marketing outlets, they are capable of offering quality products and speedy ser-vice to each and every local customer. They are serving customers not only in Japan but also overseas end users through the affiliates operat-ing in Vietnam, China, Indonesia, India and USA.
