Company introduction
Founded in 2006, Hefei WangQin Spring Co., Ltd. Over 20 years of experience in door springs and supporting hardware. We integrate R&D, design, precision manufacturing, custom processing, and after-sales service, supplying reliable hardware solutions to door manufacturers at home and abroad. Located in Hefei, Anhui's National Garden City, we benefit from convenient transport and sound industrial infrastructure. Leveraging local industrial strengths, we deliver high-compatibility springs and hardware, gaining solid market recognition and a good global reputation. I. Core Business Scope We offer dedicated hardware solutions for garage, automatic, and industrial doors. Our main products include door torsion springs and extension springs, matching residential garage doors, factory doors, roller shutters and electric doors. We also supply one-stop custom accessories such as spring cones and cable drums, covering residential, commercial, and industrial projects. Integrated supply eliminates scattered procurement and improves part compatibility for clients. II. Production and R&D Capabilities Innovation underpins our development. Our veteran technical team optimizes automatic door balance springs and has formed a complete standardized design system. We customize springs according to door weight, size, and usage frequency to fix jamming, uneven stress, and motor overload issues. Equipped with full production and testing equipment, we run full-process quality control from raw material screening to finished fatigue and load tests. We strictly reject defective products to guarantee stable, durable goods. III. Core Product Advantages Our springs adopt premium raw materials and advanced craftsmanship, featuring high toughness, fatigue resistance, stable load capacity, and smooth operation. They allow easy manual opening during power cuts. When electrically driven, they balance door weight to reduce motor wear and prolong system service life. Adaptable to frequent long-hour use, our products are widely favored by door factories and engineering companies worldwide. IV. Business Philosophy and Development Prospects We adhere to "Customer First, Quality Foremost, Reputation Oriented". Stable quality, reasonable prices, and full pre & after-sales service win long-term trust from global partners. Going forward, we will keep optimizing production, upgrading equipment, and enriching product ranges while expanding domestic and overseas markets. We aim to provide superior products and professional support, cooperating with door manufacturers for mutual win-win sustainable development.
