  • Overview of PCS product classification

    Overview of PCS product classification-There are about 211 models of the design, with 33 models of independent R&D. The economy models are 679 in total. Our products are divided into 4 categories according to different applications, Handle, lock, hinge and Door accessories. Each category is subdivided according to the market habits to make it easier for customers to search. ‘Recommended models’ are categorised according to their original purpose and according to the market need they address. Take Lever handle as an example:

1, Surface Preparation Requirements
PVD Coating:
Requires Class-A surface finishing (Ra ≤ 0.2μm per ISO 1302)
Demands precise tooling marks alignment (≤0.05mm deviation)

Powder Coating:
Tolerates surface roughness up to Ra 3.2μm (ASME B46.1)
Sandblasting at 80-100 grit suffices for adhesion enhancement

2, Application Environment

Coating TypeRecommended UseUV Exposure Limit
Standard PowderIndoor applications≤200kLux/year (EN 12206)
NTUV PowderOutdoor/balcony use≤600kLux/year (AAMA 2604)

Note: NTUV coating extends color retention to 5+ years under 450nm UV radiation (per ASTM G154 Cycle 4)
