China — and Foshan in particular — produces the majority of the world's architectural door hardware. Foshan's hardware manufacturing cluster, centred around Nanhai and Shunde districts, has been producing hinges, handles, locks, and closers for international markets for over three decades. The cost advantage over European and North American manufactured hardware is significant, particularly for mid-range and commercial-grade specification.
The key challenge for buyers in the US, UK, Australian, and European markets is certification. Door hardware for commercial and residential construction projects must meet specific standards — ANSI/BHMA in North America, EN standards in Europe, and AS 4145 in Australia. Not all Chinese factories hold these certifications, and some factories make claims that do not withstand verification.
ANSI/BHMA Certification Explained
ANSI/BHMA (American National Standards Institute / Builders Hardware Manufacturers Association) certification is the primary standard for architectural hardware in the US and Canadian markets. The relevant standards are ANSI/BHMA A156.1 for butts and hinges, A156.2 for locks and lock trim, A156.4 for door closers, and A156.13 for mortise locks.
Each standard has three grades. Grade 1 is the highest, intended for heavy commercial use. Grade 2 is for light commercial and residential applications. Grade 3 is residential only. For commercial construction projects, Grade 1 is typically specified.
ANSI/BHMA certified products are listed in the BHMA Certified Products Directory, which is publicly searchable at bhma.org. This is the most reliable way to verify a Chinese factory's ANSI certification claim — if the product is not in the BHMA directory, the certification claim cannot be relied upon.
EN and CE Certification for Europe and UK
European door hardware certification falls under several EN standards. EN 1906 covers lever handles and knob furniture. EN 1154 covers hydraulic door closers. EN 12209 covers mechanically operated locks and latches.
CE marking is required for door hardware placed on the European market. The CE mark must be accompanied by a Declaration of Performance (DoP) that identifies the notified body that assessed the product and lists the declared performance characteristics. Buyers should request the DoP and verify the notified body identification number against the NANDO database (nando.ec.europa.eu).
For the UK market post-Brexit, UKCA marking is technically required, though the UK government has extended the acceptance of CE marking for construction products. Buyers specifying for UK projects should confirm current requirements with their clients.
AS 4145 for Australia and New Zealand
AS 4145 is the Australian Standard for locksets and hardware. It covers mechanical performance, security rating, and finish durability. Products certified to AS 4145 must be tested by a NATA-accredited laboratory or an internationally recognised equivalent.
AS 4145 certification is separate from ANSI and EN certification and is frequently overlooked by buyers who assume European certification is accepted in Australia. It is not. Buyers sourcing for Australian projects should confirm AS 4145 certification specifically.
Dahua Door Hardware in Foshan holds ANSI/BHMA certification for its hinge and handle ranges, CE marking to EN 1906 and EN 1154, and AS 4145 certification for its lockset range — one of the more complete multi-market certification sets among Chinese door hardware manufacturers.
PVD and Surface Finish Durability
Surface finish durability is one of the most common quality complaints in imported door hardware. Electroplated finishes — chrome, satin nickel, antique brass — can fail prematurely if the plating chemistry is incorrect or the substrate is not properly prepared.
PVD (Physical Vapour Deposition) coating is significantly more durable than electroplating. PVD matte black, brushed gold, and satin brass finishes typically achieve Vickers hardness above 2,000 HV and salt-spray resistance exceeding 720 hours. Electroplated equivalents typically achieve 200 to 400 hours salt-spray resistance.
Ask factories for salt-spray test certificates for the specific finish you are ordering. Certificates should state the test duration, the test standard (ASTM B117 or ISO 9227), and the result. Factories without documented salt-spray test data are a higher risk for finish failures in service.
