Door Closers
Power sizing, ANSI/BHMA A156.4 grades versus EN 1154 classes, fire-door listing evidence, ADA opening-force limits, tariff classification, and the documents to request from a supplier.
Read the guide →Architectural Hardware & Fasteners
Buying guides for hardware categories most frequently sourced from Chinese suppliers — door hardware, cabinet hardware, and fasteners. Each guide covers what to specify, which questions to ask, and what documentation to request, with any claims about standards and grades verified before publication.
Every guide is dated and sourced. Every guide below is dated and names the official or standards-body source behind each figure.
Door Hardware
Hinges, handles, locksets, closers, and related architectural door items: specification inputs, finish matching, and the performance questions to raise with suppliers.
Read the guide →Cabinet Hardware
Hinges, knobs, pulls, catches, drawer slides and cabinet locks: materials and finishes, ANSI/BHMA A156.9 and EN 15570 / EN 15338, corrosion-test evidence, and the spec sheet that prevents disputes.
Read the guide →Fasteners
Screws, bolts, nuts, washers, and anchors: how naming and grading systems map across markets, and how to verify material and coating claims.
Read the guide →Door Locks & Lock Hardware
Mortise, cylindrical, auxiliary and multipoint locks, cylinders and keying, electrified and smart locking, fire-door listing, accessibility and finish codes: which ANSI/BHMA standard governs each product, and what to put in the enquiry.
Read the guide →Industrial Valves
How China's national standards organise industrial valves — terminology, materials, pressure testing, marking and the type standards a specification should name.
Read the guide →Wire Mesh
How China's national standards organise welded, woven, screening and expanded mesh — the numbers a specification should name, and the one that misleads.
Read the guide →Wire Rope
Why one Chinese term covers rope, conveyor-belt cord, rope ends and slings — the numbers in force, and the withdrawn editions that still look current.
Read the guide →Window Hardware
The GB/T standards that govern window hardware, the fittings the register does not list at all, and why the obvious search terms return nothing.
Read the guide →The standards question. Depending on your market, project specifications may reference US-developed standards such as ASTM, ask for CE-marked products within the European Economic Area, or require safety-related marks. We will explain what these references typically mean for hardware buyers — without substituting for a qualified compliance review.
