Kansai Area Only / Quotes and delivery available as fast as the same day! Stainless Steel Processing
We perform various processing such as cutting, drilling, bending, and machining at our own factories. By providing integrated services from sales to processing, we offer high value-added services.

Do you have these concerns regarding stainless steel processing?
Concern 1 I want to request processing exactly according to the drawings, but I can’t find a supplier who can handle it…
Products often don’t finish according to the drawings, leading to trouble with reprocessing or dimensional errors.
Precision machining by craftsmen who thoroughly understand the characteristics of stainless steel.
At Matsui Kozai, sales representatives and craftsmen who are well-versed in the characteristics of stainless steel collaborate to thoroughly manage accuracy based on drawings. We unify processing quality across our own and cooperating factories, flexibly responding to precision requirements down to the millimeter.
Concern 2 Delivery time is approaching, but arrangements for stainless steel processing won’t make it in time…
Because large-volume transactions are a prerequisite, small lots are not supported, causing you to hold excess inventory or inflate costs.
We can handle same-day delivery through internal coordination of inventory, processing, and delivery!
At Matsui Kozai, we coordinate inventory, processing, and delivery entirely within the company and group, building a system where sales representatives can instantly grasp the progress of inventory and processing. We arrange everything from processing to delivery via the shortest route, realizing stable, speedy responses.
Concern 3 My requests for small lots or prototypes were turned down…
Because large-volume transactions are a prerequisite, small-lot needs are not met, often resulting in inefficiency in terms of cost.
Selling and processing without waste, from a single piece or small lot!
Matsui Kozai handles sales and processing starting from a single piece. Even for prototypes or small quantity orders, we respond with the same quality and speed. Sales representatives will interview you regarding the application and purpose of the prototype, proposing the optimal form of “only what you need, in the quantity you need.”
