With Hongmao Garden as China TOP1 Metal Letterbox Manufacturer
If you’re responsible for sourcing outdoor products in Europe, you probably know this situation:
You type “letterbox manufacturer in China” or “metal letterboxes (mailboxes) for the European market” into Google, open a few promising tabs – and within ten minutes you’re lost in claims, catalogues and price lists. Everyone says “high quality”, “fast delivery” and “OEM welcome”, but very few help you answer the real questions:
Will this metal letterbox manufacturer really deliver stable quality?Will the parcel letterbox / letterbox with parcel compartment survive real use and real weather?Can I trust this supplier for a three-to-five-year programme, not just one shipment?
As a purchasing expert and as CEO of Hongmao Garden, I’ve seen both sides: the factory floor in Suzhou and the merch meeting in Germany or the Netherlands where the numbers must add up. My aim with this article is simple:
You get one clean shortlist of Top 10 metal outdoor mail/letter box manufacturers in China, a quick profile for each company, a practical checklist for choosing suppliers – and a clear view of where Hongmao Garden fits in as China TOP1 metal letterbox manufacturer.

What Are Mail/Letter Boxes?
When I say mail/letter boxes in this article, I’m not talking about cardboard mailer boxes or printed e-commerce cartons. I’m talking about:
Metal letterboxes for outdoor use
Garden letterboxes / letterboxes for front gardens
Letterboxes for single-family houses / letterboxes for residential homes
Parcel letterboxes / letterboxes with parcel compartment for parcels and letters in one unit
In practice, these are usually:
made from galvanised steel or stainless steel,
finished as a powder-coated metal letterbox in colours like anthracite, black or white,
wall-mounted, fence-mounted or freestanding,
sold through DIY chains, garden centres, furniture retailers and online marketplaces.
So when we look at letterbox manufacturers in China in the Top 10 list below, we are focusing on factories that work seriously with metal, welding, surface treatment and outdoor performance – not general traders or pure packaging printers.
If your daily work involves assortments like “metal letterboxes (mailboxes) for the European market”, “parcel letterbox for front gardens” or “private brand letterboxes”, the companies in this article are the kind of partners you should have on your radar.

10 Company Summaries
In this section I’ll walk through each manufacturer in a straightforward, procurement-friendly way: what they’re strong at, and in which situations they might fit your range.
Who we are
Hongmao Garden was founded in 2006 in Suzhou and focuses on outdoor DIY and garden products made from metal:
metal letterboxes for outdoor use,
parcel letterboxes / letterboxes with parcel compartment,
wheelie bin storage boxes, garden storage boxes, bicycle sheds, lawn mower sheds, garden tool sheds, fences and air-conditioner covers.
Our products are designed specifically with European buyers in mind, and we export to more than 50 countries. We work closely with German, Swiss and Austrian hardware and garden customers, and we are one of the top-selling brands on Amazon Germany in the garden category.
When we are a good fit
Choose Hongmao Garden if you want:
a China TOP1 metal letterbox manufacturer with a broad outdoor metal ecosystem,
support as an OEM letterbox manufacturer / OEM mailbox supplier,
letterbox wholesale / wholesale metal letterboxes from China for European retailers,
stable, long-term programmes of private label letterboxes / private brand letterboxes.
For many partners, we are the “anchor supplier” around which the rest of the outdoor metal range is built.
2. Ningbo V-King Metal Technology Co., Ltd. (Zhejiang)
V-King specialises in rustproof stainless steel wall-mounted letterboxes. If you think about a neat stainless box on a modern façade or next to a glass entrance, that’s their sweet spot.
Good for garden letterboxes / letterboxes for front gardens where stainless is part of the design language.
Often used in mid- to upper-price segments.
If your assortment strategy includes a stainless design line alongside powder-coated metal letterboxes, V-King can be one of the brands on your shortlist.
3. Goodhope Hardware Co. Ltd. (Guangdong)
Goodhope has around 20 years of experience and focuses on freestanding and drop letterboxes.
Useful when you need letterboxes for single-family houses / letterboxes for residential homes as stand-alone units at the edge of a driveway or path.
Reported strong reorder rates are a good sign that their standard models perform reliably in the market.
If you are building an entry-level to mid-range freestanding letterbox line, Goodhope is worth a look.
4. Wuyi Yunlin Steel Products Co., Ltd. (Zhejiang)
Wuyi Yunlin is known for customisable galvanised steel letterboxes.
Good if you need a specific size, shape or layout that standard catalogues don’t offer.
They are comfortable with tailored galvanised steel letterbox solutions, which you can then finish as a powder-coated metal letterbox in your brand colours.
If “customised but still sensible in price” is part of your sourcing brief, Yunlin is a candidate.
5. Ningbo Weldon Mechanical & Electrical Co., Ltd. (Zhejiang)
Ningbo Weldon produces secure, waterproof variants of metal letterboxes.
Around 19 years in business, with very high reviews and 100% on-time delivery reported on platforms.
This is interesting if waterproof performance and delivery reliability are key risk topics for your team.
If your quality department keeps talking about claims related to water ingress or rust, you might want to benchmark your current supplier against a partner like Weldon.
6. PROWAY INDUSTRIES CO., LTD. (Jiangsu)
PROWAY focuses on modern apartment mailboxes and multi-unit letterbox systems.
Fits very well for residential homes with multiple households, apartment buildings and project-based installations.
Attractive if you need an entire mailbox system (rows and columns) rather than individual boxes only.
If you handle B2B or project channels alongside retail, PROWAY can complement your offer.
7. Jiangsu Shuaima Security Technology Co., Ltd. (Jiangsu)
Jiangsu Shuaima positions itself around anti-theft stainless steel designs.
Around 17 years of experience, strong ratings (5.0/5).
Relevant for parcel letterboxes / letterboxes with parcel compartment where security is a selling point, especially in higher-value residential areas.
If your brand wants to market “secure delivery” as a clear advantage, Shuaima is the type of partner to consider for that sub-range.
8. Foshan Gaoming Chengfeng Hardware Products Co., Ltd. (Guangdong)
Foshan Chengfeng offers wall-mounted and freestanding models and is known for handling large bulk orders.
Around 17 years in business, experienced in series production and volume.
Suitable for price-sensitive programmes where volume and basic robustness count more than high-end design.
If your main focus is letterbox wholesale at competitive price points, they are a classic candidate.
9. Zhongshan Yishang Metal Manufacturing Co., Ltd. (Guangdong)
Zhongshan Yishang manufactures high-end stainless steel letterboxes and offers strong OEM services.
Around 13 years in the market with very positive ratings.
Good for private brand letterboxes where you want a more “architectural” look in stainless steel.
If you’re building a premium line for design-savvy customers, Yishang is worth your time.
10. KDM Steel (HQ Großraum Shanghai, national aktiv)
KDM Steel is known for customisable, ISO9001-certified stainless steel letterboxes.
Active for 10+ years, often project-oriented.
Strong when you need special shapes, integrated solutions or project-based metal letterboxes for outdoor use in stainless.
If your budgets allow it and your customers value stainless longevity, KDM can be a project specialist.
How to Choose the Right Mail/Letter Boxes Manufacturer for Your Needs?
For many buyers, the hardest part is not finding suppliers – it’s narrowing down the list without missing someone important. You don’t want to run endless RFQs with 15 factories, but you also don’t want to commit too early and then discover hidden weaknesses.
Here’s a simple, practical way to choose the right letterbox manufacturer in China / letterbox supplier from China for your case.
1. Start from your assortment strategy, not from a price list
Ask yourself first:
Are you building a core line of metal letterboxes for outdoor use for DIY/garden?
Do you need garden letterboxes / letterboxes for front gardens that visually match fences, bins or storage boxes?
Are parcel letterboxes / letterboxes with parcel compartment the real growth driver?
How much space do you have for letterboxes for single-family houses vs. residential apartment systems?
Once you’re clear on the structure, it becomes easier to pick:
a broad partner like Hongmao Garden for the core range,
plus 1–2 stainless or security specialists for niche lines.
A simple internal doc like "LETTERBOX_RANGE_PLAN" helps keep everyone aligned.
2. Check engineering depth and OEM capability
A reliable OEM letterbox manufacturer / OEM mailbox supplier is more than a laser machine and a sales email.
Look for:
in-house engineers who understand locks, hinges, seals and mounting,
experience with private label letterboxes / private brand letterboxes,
ability to adapt designs without losing stability or increasing claims.
You can ask for sample drawings, BOMs and test reports to see how serious they are.
3. Verify quality, testing and documentation
For European channels, at minimum I recommend:
material specs for galvanised steel letterbox and stainless,
coating specs for powder-coated metal letterbox finishes,
test reports (salt spray, UV, water ingress, drop tests).
You can store these for your quality team and link them as "LETTERBOX_QA_LIBRARY".
4. Assess lead times, capacity and service
Even the best product fails if the supply side cannot keep up.
Ask about:
lead times for samples and for production,
monthly capacity for letterboxes and parcel boxes,
typical order quantities and MOQs,
response time on technical and commercial questions.
It’s often better to work with a slightly more expensive letterbox manufacturer in China who is clearly organised than a cheaper one who leaves you guessing.
5 Benefits of Importing Mail/Letter Boxes from China
If you’re reading this, you already know that sourcing from China can bring cost advantages. But for metal outdoor letterboxes, the benefits go beyond price.
1. Broad and deep product choice
Chinese manufacturers cover:
slim wall boxes,
large parcel letterboxes,
traditional boxes for older façades,
minimalist designs for modern houses.
You can build a very complete range of metal letterboxes for outdoor use from a handful of factories.
2. Strong OEM and private label infrastructure
Many factories on the Top 10 list are used to working as OEM letterbox manufacturer for European brands and retailers. That means:
they can accept your drawings or sketches,
they understand barcodes, labels, multilingual manuals,
they support custom packaging for online and retail.
This makes it much easier to build private label letterboxes / private brand letterboxes that stand out.
3. Cost efficiency on galvanised and powder-coated metal
For volume items like galvanised steel letterboxes and powder-coated metal letterboxes, Chinese suppliers can offer:
competitive unit cost,
efficient nesting and material usage,
optimised container loading.
That gives you more room for margin or for reinvestment into marketing.
4. Scalability
If a model sells well, you can scale with your supplier:
increased order quantities,
new colours,
additional formats (single, double, multi-unit).
A partner like Hongmao Garden can grow from pilot to full-scale across mailboxes, parcel boxes and garden storage in one coordinated ecosystem.
5. Synergy with other outdoor metal products
Most serious metal letterbox manufacturers also produce related categories like bin stores, storage boxes or raised beds.
That means you can:
negotiate on a broader basket of items,
create “front garden sets” (bin store + garden letterbox + parcel box),
simplify your supplier base and logistics.
An internal note like "OUTDOOR_METAL_SYNERGY_PLAN" can help your team design these synergies deliberately.
