Trustworthy and Reliable Quality Control System
With a thorough quality control system from fabrication to inspection, we can provide high-quality products. With the acquisition of ISO9001 certification, JIS display permission, certification from various shipping bureaus, and multiple vendor registrations, orders can be placed with peace of mind.
Short Term Response
We can manufacture rushed orders thanks to our wealth of materials in storage and detailed processing management. We are always available to discuss immediate trouble, tight construction periods, etc.
Multitude of Products
Carbon steel, steel alloy, and steel for low temperatures can be made according to various overseas specifications (ASME, ASTM, DIN etc.) in addition to JIS standards and shipping standards. Fabrication allows for an outer diameter range of 4 mm to 165.2 mm. Also, we conduct irregular steel pipe forming and various secondary processing through independent technology to meet a wide range of client needs.
Maximum Length 21.5m
We can produce steel tubes of up to 21.5m.
High Dimensional Precision
Compared to hot-rolled and heat-formed products, we can produce steel pipe with a higher degree of dimensional precision.
Smooth Finish
Outer surface is smoother than pipes made by heat processing. The inner surface is also beautifully finished - a particularly difficult task for pipe post-processing.
Narrow Diameter Pipes
We can manufacture narrow diameter pipes not possible with heat fabrication / hot rolled manufacturing.
