A little more detail

Questions, answered.

Will this form send my enquiry?

If the form is available, it sends your enquiry to the HAIHUI business inbox. The confirmation reports mail-server acceptance and includes a reference; it cannot guarantee final inbox delivery. If unavailable, nothing is sent and you can save a brief on your device.

Can I upload drawings now?

The website form does not accept drawing uploads. Include drawing references in your brief and send files through the published business email after checking permission.

What should I prepare for a quotation?

Include the opening or component drawings, dimensions, quantity, finish reference, installation location, required performance and target programme. Avoid confidential or unnecessary sensitive information in your enquiry.
