13.5mm Wind Stay (Light Duty)
★ Applicable to standard C notch profiles.
★ Limit the Angle of window sash opening, its role:
1) Prevent the strong wind from blowing the window sash to close suddenly and damage the window.
2) Prevent children from falling through the window gap.
★ Selection of high quality (304) stainless steel manufacturing.
★ In line with China JG/T128-2007<< building doors and Windows hardware support file >> standard.
★ With the improvement of technology, some parameters will be changed, please take the material as the standard.
1. The raw materials of the castings are made of four-in-one zinc alloy, and the advanced material formula (±50 ℃) does not deform or break.
2. All stainless steel parts are made of 304 material, containing 7.5-8.5 nickel, which does not rust.
3. The plastic parts in the fitting system are made of high-strength wear-resistant nylon PA66 material, which will never be damaged.
4. The spraying part is sprayed with polyurethane material, the thickness is 45μm-100μm, and the dry adhesion is more than 10 grades, all exceeding national standards
5. The production equipment for zinc and aluminum die-casting machine is 120Ton, and the automatic punching machine is 180Ton,which ensure the hardness, strength and toughness of the casting. Inward opening, inverted, inner and outer casement windows open and close 450,000 times of opening and closing cycles, no distortion of parts, normal use
6. The surface treatment of the plated parts is a trivalent chromium electroplating process, the thickness of the plating layer is 45μm-100μm, and the salt spray test is 120 hours without pinholes, bulging and rust.
After nearly a year of repeated research and designing a mold opening test, Yuqiang Hardware has successfully improved the aluminum alloy casement window hinges, connectors, and inner opening and inverted hinge chains from the original aluminum alloy extrusion material to carbon steel. Stamping parts ensure that the load-bearing capacity of the accessories is increased. The original aluminum alloy hinges can load 70kg, and the carbon steel hinges can load up to 180kg without deformation or fracture.
It has fundamentally solved the load-bearing problem of super-standard large windows and triple-glazed windows. Now this product has been declared a national patent, leading other domestic brands.
