The company

A hardware manufacturer, not a trading office

The profile below is rewritten from the company introduction in the AOHUALUN catalogue. Figures stay as the catalogue gives them.

温州欧之伦建筑五金有限公司 — AOHUALUN — produces window and door hardware fittings for thermal-break, aluminium, PVC and curtain wall systems. The plant covers 10,800 m² and combines design and mould development, stamping, die casting, injection moulding, surface finishing and assembly in one place.

The company has worked in door and window hardware for many years, with design and development carried out in-house under the principle the catalogue puts as people-oriented and ready to innovate. The range is broad enough to fit a standard window and deep enough to match a specific profile groove, which is what a window maker needs from a supplier.

The catalogue records that products are supplied to customers in Europe, the Middle East and South-East Asia as well as on the domestic market. Its project pages are residential developments in China; those are domestic references and are described on the manufacturing and quality page without being presented as overseas projects.

Company details, including the registered name and address, are kept on this page and on the contact page in the same form used on the catalogue cover.

Philosophy

What the company says it stands on

Rewritten from the enterprise philosophy page of the catalogue: the same three commitments, in plainer English.

Quality is decided in the detailThe catalogue puts it as quality in the smallest things and service in the details. For a hardware supplier that means the groove clearance, the handing, the cut length of a rod and the finish on a handle — the points where a set either fits a window or does not.
Cooperation is how we learnEvery order with a window maker also teaches something about a profile, a sash size or a market. That is why we ask for the section drawing and the sash size before quoting, and why the catalogue pages on this site keep the fitting data a buyer needs to check us.
Quality is the life of the enterpriseThe company states this plainly, and backs it with its own production and inspection equipment. Design, tooling, casting, moulding, finishing and assembly all sit in one plant, so a problem can be traced to the step that caused it instead of being passed between suppliers.
