Industrial-Grade Transmission Hardware & Heavy-Duty Mechanical Systems

Integrating JIEDO, CMECH, HOPPO, and SINCEM window-control hardware with Nano-Blue anti-corrosion gearboxes, tested for 50,000 to 100,000 smooth operating cycles.

BC-115, BC-118 and BC-120 thermal-break casement window hardware system
SINCEM 15-inch 304 stainless-steel heavy-duty friction stay

SINCEM 15-Inch 304 Stainless Friction Stays

Channel-locked stays pass 240-hour salt-spray testing and safely support 60–80 kg sash loads without wind shake, sagging, or detachment.

HOPPO and CMECH baseless minimalist casement window handle

HOPPO / CMECH Baseless Minimalist Handles

Aerospace-alloy handles pair a reinforced 10 mm anti-torsion spindle with tactile 30-degree mechanical feedback and durable PVDF finishes.

JBS side-mounted concealed locking and transmission hardware

JBS Side-Mounted Concealed Hardware

Concealed locks and hinges eliminate visible hardware, preserving the pure architectural sightline of ultra-slim sash and mullion profiles.

Heavy-duty anti-drop and concealed screen-sash safety hardware

4.0mm Anti-Drop & 180° Screen Hinges

Thickened glass-sash hinges resist drop loads while concealed 180-degree screen hinges combine high-rise safety with panoramic ventilation.

BC-115/118/120 Architectural High-Weatherability Surface Finishes & Color Palette

Finished via automated vertical coating lines using Tiger and AkzoNobel coatings, passing 1000-hour salt spray testing to prevent UV fading, chalking, and coastal peeling.
