Shanghai Malaxy Industry Co., Ltd.









We are a professional 100% self-owned screw manufacturing factory based in China, with years of dedicated focus on the R&D, production and sales of construction and building screw fasteners. Different from comprehensive hardware trading companies that handle all kinds of fasteners, we have always concentrated all our production resources, technical teams and quality control systems on the segmented screw product track, focusing on providing stable, high-quality and cost-effective screw solutions for global construction contractors, hardware distributors, roofing engineering and furniture manufacturing enterprises.
Our factory has complete independent production workshops, including cold forging forming, precision thread processing, heat treatment strengthening, surface anti-corrosion coating and finished product sorting workshops. We adopt fully automated production equipment and standardized production processes, with stable daily output and large-scale bulk order delivery capacity. Meanwhile, we have built a professional laboratory to conduct regular tensile strength tests, hardness tests and salt spray resistance tests for all batches of products, strictly controlling every production link from raw material incoming inspection to finished product delivery.
In terms of quality and environmental compliance, all our products and production systems have obtained ISO9001 quality management system certification, CE safety certification, RoHS environmental protection certification and REACH chemical compliance certification. In response to the global low-carbon environmental development trend and international trade carbon barrier standards, our factory has also completed relevant carbon emission compliance certification, fully meeting the import and market access requirements of Europe, the United States, Southeast Asia, the Middle East, Africa and other mainstream global markets. All qualifications are complete and traceable, supporting customer third-party inspection and factory audit at any time.
Over the years, we have been deeply engaged in overseas B2B fastener trade, adhering to the factory-direct FOB supply model without any middlemen. We have established long-term stable cooperative relations with buyers from India, Nigeria, the United States, Vietnam, Indonesia, Thailand, Poland, Egypt, Saudi Arabia and other countries and regions. We are familiar with the metric and imperial size standards, local building specifications and market procurement habits of different regions, and can flexibly provide customized services including product size, surface treatment, packaging and logo printing. With reliable product quality, competitive factory prices and flexible delivery cycles, we have won consistent recognition and long-term trust from global customers.
We always take customer demand as the core, focus on product quality improvement and technological innovation, and insist on professional segmentation rather than blind diversification. We sincerely welcome global hardware distributors, engineering contractors and factory purchasers to consult, sample and visit our factory for cooperation.
1. Self-Drilling Screws
As our flagship hot-selling product, our self-drilling screws include bi-metal self-drilling screws and 300 series stainless steel self-drilling screws. With precision drill tip design, they can complete drilling, tapping and fastening in one step without pre-drilling, which greatly improves the construction efficiency of metal roofing, steel structure and light steel engineering. We support multiple drill point specifications and customized anti-corrosion coatings. The matching EPDM waterproof rubber washer has good anti-aging and leak-proof performance, which is very suitable for outdoor building engineering in high-temperature, rainy and coastal high-corrosion environments. This product is in long-term stable demand in the Indian infrastructure, Nigerian construction and American metal building markets.
2. Roofing Screws
We provide professional customized roofing screws for color steel tile fixing, solar bracket installation, metal wall panel and roof waterproof fastening scenarios. All products are made of high-quality raw materials, with optional galvanizing, ceramic coating, stainless steel and other surface treatments, which effectively resist rust and ultraviolet aging. The perfectly matched rubber washer fits closely to the screw body, completely avoiding water seepage and loosening problems caused by long-term outdoor use. We have complete product specifications and support customized color head treatment according to customer local project standards, with sufficient spot inventory and fast FOB delivery for bulk orders.
3. Concrete Screws & Tapcon Concrete Screws
Our concrete screws and Tapcon concrete anchor screws are professional masonry fastening products, specially developed for concrete, brick, stone and wall base fixing. The unique carbide-tipped and high-precision thread design enables the screws to grip the base firmly, with strong tensile resistance and anti-loosening performance, no need for expansion tubes, and simpler and more efficient construction. They are widely used in building infrastructure renovation, pipeline fixing, curtain wall installation and large-scale municipal engineering projects, and are favored by engineering contractors in Africa, the Middle East and South Asia.
4. Wood Screws & Construction Screws
Our full-range wood screws are applicable to furniture production, wooden structure construction, wooden deck installation and other scenarios. The sharp deep thread design ensures strong holding force on solid wood, density board and particle board, and the Type 17 cutting tip effectively prevents wood cracking during construction. Multiple head types such as countersunk head, wafer head and hex head are optional. Conventional construction screws cover the fastening needs of light metal and composite building materials, suitable for various residential and commercial construction projects. The factory has stable mass production capacity, supporting both small trial orders and large batch bulk orders.
5. Corrosion-Resistant Screws & Straw Rope Nails
Aiming at the high humidity, heavy rain and high salt fog environment in coastal areas of Southeast Asia, Africa and the Middle East, we have launched customized high corrosion-resistant screws and supporting straw rope nails. Through advanced electroplating, passivation and stainless steel raw material processing technology, the products have excellent salt spray resistance and anti-rust performance, which can adapt to long-term outdoor harsh working conditions and effectively extend the service life of building fasteners.
Product Quality & Compliance Advantages
All our core screw products have passed CE, RoHS, REACH, carbon emission compliance and ISO9001 full system certification. From raw material procurement to factory delivery, every link has standardized quality inspection records. We strictly control product size tolerance, surface treatment quality and mechanical properties to ensure that all products meet international industry standards and regional market access requirements. Adhering to the factory direct sales model, we provide customers with cost-effective formal compliant products and reliable after-sales guarantee, and have always maintained a zero-major-quality-complaint market record.
Service Advantages
We support OEM and ODM customized production, flexibly matching imperial sizes for the US market and metric sizes for European, Indian and Southeast Asian markets. With low MOQ for new customer trial orders and sufficient capacity for large engineering bulk orders, we provide stable FOB port delivery services. We have rich experience in participating in global fastener exhibitions and serving international customers, and can quickly respond to customer consultation, sample application and customized demand docking.
