Stainless Steel C Groove Friction Hinge for   Standard Screen Window and Door

Aluminum Alloy C groove Friction Hinge for Standard Screen Window
 




From 2003, HOPO experienced several steps of development in aspects of products, services, and brand image.
The initial development of the company was powered by the market demand for sliding windows and doors, while European companies had few solutions for it.  Rollers for different grooves, various locking solutions for C groove leaf profiles, many flush locks and pull handles have been developed for sliding doors and windows. The smart design of the C groove locking system achieved several solutions, unlockable solution with square spindle handles or folk handles, lockable solution with cylinder for entrance door, pull handle for heavy door solutions, that covered all range of people's demand for sliding windows and doors.  From the cooperation with and services to fabricators, HOPO became the leading brand in this field.  Patents have been registered for hundreds of products.
Based on introspection of traditional European products, HOPO has redeveloped some new solutions, tilt-turn windows for alu-wood profiles, with sliding stay functions, with fixed turning-width solutions; lift-sliding door fittings with free-corner solutions; casement windows and doors with K groove profiles.  Optimized structure designs and materials utility make HOPO fittings with more fluent operating experience and prolonged life time.  In these product ranges, the company's strategy is to make the best windows and doors hardware in the world.  These quality products brought very positive influence to the brand image of HOPO in the market.
In procedure of internationalization, we achieved an idea that different markets or market at different level of development may have different demands for windows and doors. These customized or bespoke system design targeted directly to requirements from certain markets. Some regions may have special requirement for thermal break system, while other regions may focus specially on extreme water-proof or typhoon resistance quality. Some regions may have special requirements for safety or security.
All our efforts of products and services developments are finally targeting on customers, requirements for windows and doors.  And we will not stop at any success achieved up to now and face to challenges from any aspects or directions.
HOPO quality experiment center, a test center to check the quality of spare parts and finished products, is designed and formed by HOPO QC department. Tests of endurance, weather-proof, over-load capability are designed to simulate real application situations. In this way, we can discover problems more directly and efficiently than third-party test, thus solving the problem more effectively.  Certificate application for patented new products, especially system solution for certain window operation has been done in cooperation with some European test companies according to EN standard.
