A Technical Trading House Between the Mill and Your Press

Cold rolled thin gauge steel and aluminum coil, slit to the width you actually run.

Who We Are

What a Technology Trading Company Actually Does

Hangzhou Making Industry Co., Ltd is a technology trading company. We add technical and economic value in the link between the mill that rolls the metal and the manufacturer that forms it, and we act as agent for a number of leading steel and aluminum mills in China.

We work in selected niches of the market for cold rolled thin gauge metal and aluminum coil. Our customers primarily operate in the manufacturing industry, and they come to us when a standard mill offering does not match the gauge, width or temper their process needs.

Trading in standard products is the foundation of the business. Technical competence, long-term customer relationships and an understanding of how our customers actually run their lines regularly turn into deeper cooperation and into customized products and solutions. Around half of our sales are standard products and half are customized.

How We Operate

Where We Sit in the Supply Chain

Our base at Linjiang Industrial Park in Xiaoshan District Hangzhou
We are based at Linjiang Industrial Park in Xiaoshan District, Hangzhou, which puts us inside one of the densest metal processing regions in China and within reach of Ningbo and Shanghai for export.
Rolling line at a partner steel mill
We act as agent for a number of leading Chinese steel and aluminum mills. Mills differ in rolling practice and in how tightly they hold gauge at the thin end, so the choice of mill is part of the specification.
Incoming inspection checking strip thickness and surface condition
Thickness across the width, slit width, edge condition and surface are checked against the order before a coil is released, because a problem found here is cheaper than one found on your press.
Our Approach

We Start From the Part Not From the Grade

An enquiry that arrives as a grade and a tonnage hides the three things that actually decide the specification: how the part is formed, what it has to survive, and what width the line runs. We ask those first.

  1. Understand the part, the forming process and the service environment
  2. Fix grade, temper, surface and coating weight together as one specification
  3. Place the order with the mill whose rolling practice suits that gauge and grade
  4. Slit to the developed width your line needs rather than to a catalogue size
  5. Check and pack for the route, then stay the contact point after arrival

What We Will Not Claim

We do not publish capacity figures, certification lists or customer names that we cannot evidence. If you need documentation for a specific grade or mill, ask and we will tell you what is available for that order.


About the Company

Do you own a rolling mill?
No. We are a technology trading company acting as agent for a number of leading Chinese steel and aluminum mills. The value we add is in specification and in matching the right mill to the part.
How much of what you sell is customized?
Around half. Standard products are the foundation of the business, but customized gauges, widths and tempers account for a comparable share.
Where are you located?
Linjiang Industrial Park, Xiaoshan District, Hangzhou, China. Xiaoshan is one of the densest metal processing districts in China and is within easy reach of the Ningbo and Shanghai ports.
Who will I be dealing with?
The same people who specified your material. We stay the point of contact through production, shipping and after arrival rather than handing you back to the mill.

Put Us on a Real Specification

The fastest way to see whether we are useful is to send something difficult: an odd width, a thin gauge, a temper nobody stocks.
