Buying Door Hardware from a China Factory: The Steps from Enquiry to Container

Updated 2026-11-09 · RAYEN 雷茵

Why does the process matter more than the price?

A buyer ordering a container of hardware from a factory they have never visited cannot inspect it on arrival and cannot fix a wrong hole with a file. What they are really buying is confidence that the supplier will not make a mistake. A clear process is where that confidence comes from. Here is how an order runs with us, step by step, with the guide for each.

Step 1: Find the factory and the part

Start with what the part must do and which door it goes on. Our catalogue lists every model with a specification table and photographs of the real part: 240 lever handles, 80 hinges, 105 stainless steel handles, 57 glass door accessories and more. If no model fits, you can send a drawing or a sample instead.

Ask any factory which steps it runs on its own site. Our tooling, pressing, assembly and inspection are on one site in Xiaolan, Zhongshan, where we have made locks since 1999. See buying in Xiaolan.

Step 2: Send a complete enquiry

The answer is only as exact as the question. Send the product type and a reference model, door thickness, backset and spindle size, the finish, the expected quantity and delivery, any branding, and any drawing or sample. See what to send for a quote. For a whole project, send a door hardware schedule.

Step 3: Confirm the specification in writing

Before any tool is cut, you get a checklist: material, backset, door thickness range, plate size and finish. Read it line by line, and read the drawing with it; see how to read a hardware drawing. This is the cheapest place to find a mistake.

Step 4: Tooling, if the part needs it

Close to a tool we already have, a modification does it. A different structure needs a new tool. Cost and lead time are quoted per part. See from drawing to part, or copying a sample if you started from one.

Step 5: Approve a sample on a real door

The sample goes to you and onto a real door before anything is decided. Check it against the checklist, fit it, use it, and judge the finish in the room's light. Then sign it off and keep it. See checking a sample.

Step 6: Production and packing

Packed to your requirement, including your brand, colour box, instructions and barcode, with carton data before production starts. Every dimension follows the sample you signed off. See OEM under your brand.

How do you check the factory itself?

• Ask for the original certificates and check the numbers. We hold ISO 14001 and CCC.
• Ask whether the photographs show the real parts and the real works. Ours do.
• Ask which steps happen on site and which go to suppliers.
• Ask who owns the tool for your part.

Get every answer in writing. A clear written answer is worth more than a fast verbal one.

What about MOQ, price and lead time?

They depend on the model, the finish, the quantity and whether tooling is needed, so they are confirmed per model or per order. Ask for them on the exact part you want, not in general. A number from you lets us give a number back.

Next step

Send a drawing, a sample photo or a model list to [email protected], or WhatsApp the factory owner during working hours, GMT+8. The number is on the contact page. We reply with the specification, a price for your quantity, and what we need from you next.
