About Haiyan Ehons Industrial Co., Ltd.
A fastener manufacturer, distributor and exporter with two factories in Haiyan, Zhejiang.
The company
Haiyan Ehons Industrial Co., Ltd. is a fastener manufacturer, distributor and exporter. The company is organised into a foreign trade department, a domestic trade department and a manufacturing department, supported by five external agencies, and runs two separate factories in Haiyan, Zhejiang.
Production is directed by what the market actually orders rather than by what is easiest to run. The team combines senior managers, engineers, dedicated inspectors and export sales staff, so a technical question about thread form or coating does not have to travel through a trading intermediary before it reaches someone who can answer it.
Quality
Quality control and inspection follow an internal system built around international standards, and the company states that it operates an ISO 9001 quality guarantee system across production, transportation and selling. The company states that it operates advanced inspecting machines and methods.
Certification claims on this page are reproduced from the company's own statements. Ask for current certificates directly before relying on them in a tender.

Three things we will not do
Substitute a grade class
If a size is not available in the class you ordered, you get told before production, not a screw that looks the same.
Quote a coating we cannot run
Hot dip galvanising and multi-layer systems are separate process routes with their own lead times. They are quoted as such.
Publish a certificate we cannot show
Where a document exists we send it. Where it does not, we say so rather than putting a badge on a website.
Start with a sample
Samples are free. Ask for them against the finished specification, not an interim one, so the sample you approve is the part you receive.
