JIS G3445 tubing: manufacturer of carbon steel tubing for machine structural use
For customers who specify to Japanese standards or supply Asian OEMs, the reference for mechanical-use tubing is JIS G3445. We manufacture carbon steel tubing to JIS G3445, with the precision and the certificate those customers require.
What the JIS G3445 standard is
JIS G3445 is the Japanese standard for carbon steel tubes for machine structural purposes . It is the reference for tubular machinery and mechanism components made to Japanese specification, and the one requested by customers who work with JIS standards or supply manufacturers of Asian origin.
What the standard specifies
JIS G3445 defines, by grades, the requirements for carbon steel tubing for mechanical use:
The standard organises the product into several steel grades according to the required mechanical properties; the specific grade is agreed with the customer depending on the application. (The grade and exact values are confirmed in the data sheet for your order.)
Which Delmàs range meets JIS G3445
Depending on what the application requires, the OPTIM and PRECISE ranges meet the requirements of JIS G3445 for machinery components:
| Range | Role under JIS G3445 |
|---|---|
| OPTIM | Simultaneous bore and outer control for mechanisms and shafts. |
| PRECISE | High-quality bore where there is sliding or fluid flow. |
Beyond the standard: your exact size
JIS G3445 defines grades and ranges; your design defines the part. As a manufacturer —not a distributor with a closed catalogue—, we start from your drawing and adjust the size to the hundredth of a millimetre, working to the Japanese specification your customer requires. The standard is the starting point, not the limit.
Market, sectors and applications
A Japanesestandard: it is the gateway to customers who work with JIS specifications and to suppliers of Asian OEMs operating in Europe.
- Engineering / Mechanical — shafts, guides and machinery components.
- Automotive — components for manufacturers with Japanese specifications.
JIS G3445 versus neighbouring standards
JIS G3445 is the Japanese reference equivalent to the precision mechanical tubing covered in Europe by the EN 10305 series and in the US by ASTM A513. The same component can be specified in any of the three depending on the market; we manufacture to whichever the customer requires.
