A complete door hardware set is more than one handle. For commercial buildings, apartments, hotels, offices and public projects, the set usually includes Lever Handles, lock bodies, cylinders, Hinges, back plates, escutcheons, turn knobs, door stops and matching fixing accessories. Each part must fit the door thickness, opening direction, security level and installation standard.
HANGFAT focuses on architectural door hardware and stainless steel hardware products. Our product range covers lever handles, door hinges, locksets, back plates, turn knobs and bathroom accessories, helping project buyers source matched hardware from one supply system.

| Cylinder | Provides key control and access security |

For commercial door handles, EN 1906 is a common European standard covering durability, strength, safety and corrosion resistance. Grade 4 handles are designed for heavy-duty use. Salt spray testing is also widely used to evaluate corrosion resistance, and 240-hour testing is a common reference level for stainless steel architectural hardware.
A manufacturer can control material selection, machining, polishing, assembly, testing and packaging. A trader may offer many items, but matching finish, size and performance across a full door hardware set can be harder to manage.
For bulk projects, this difference matters. Handles, hinges and lock accessories must match in finish, hole position, screw type and installation tolerance. Factory-based control helps reduce installation delays and after-sales complaints.
A practical OEM / ODM process starts with door type and project use. Before sampling, buyers should confirm door material, door thickness, handle design, lock function, hinge size, finish color, corrosion requirement, packaging style and quantity plan.
HANGFAT can support customized door hardware supply for commercial buildings, apartment projects, hotel rooms, office spaces and bathroom doors. Our team can review drawings, samples or product specifications before mass production.
Reliable door hardware production includes stainless steel material inspection, die casting or machining checks, polishing review, surface treatment inspection, assembly test, torque test, pull test, salt spray test and final packing check.
For long-term supply, stable dimensions and surface finish are as important as appearance. A small mismatch in spindle size, screw hole position or hinge thickness may affect installation efficiency across hundreds of doors.
A complete door hardware set should be planned as one system, not separate parts. HANGFAT provides door handles, hinges, locksets and related architectural hardware with manufacturing support, quality control and export packing experience. This helps buyers reduce sourcing complexity and build stable supply for repeat projects.
