Second, fit simple doors/windows – meeting basic opening/closing needs for low-use, simple structures (like storage room doors). Core Advantages of Window Hinge Tests BOGO Key Advantages: Stable positioning force (90.2-95.1N, far exceeding the 40N requirement) for smooth adjustment; Precise operating force (36.8-38.5N, complying with the ≤40N standard); Strong gap consistency (0.09mm after force, much lower than the ≤0.5mm limit), ensuring good sealing. Weihui Hardware Key Advantages: Outstanding peak positioning force (92.5-98.1N, the highest among the three) for stable fixing; Light opening/closing force (32.5N, below the ≤40N standard) for easy use; Clear key parameters (35kg load-bearing, 355mm slide length) for easy matching, with all mechanical properties up to standard. Shanghai VBH Key Advantage: Tested by the national authoritative inspection center for building hardware, with professional and recognized testing qualifications. Comparison Between BOGO and Huixi Handles BOGO Great Durability: Works normally after 50,000 opening/closing tests, with only slight looseness (gap well below standard), suitable for frequent use; Strict Testing Standards: Follows national standards and adds stricter internal requirements, covering appearance, assembly, corrosion, aging and mechanics; Reliable Surface and Assembly: No flaws on exposed surfaces, firm connections, qualified coating and proper assembly size for stable use. Weihui Hardware Light Operation: Positioning torque is only 1.82N·m, non-positioning torque 0.60N·m (far below national limits), easy for the elderly and children to use; Excellent Coating Quality: Minimum coating thickness 68μm (exceeding the 40μm standard) and grade 0 adhesion (best level) for wear and scratch resistance; Good Corrosion Resistance: Passes 16-hour CASS test (grade ≥8), not easy to rust in humid or salty environments.
