SENYU’s Iron Screw and Stainless Steel Screw are essential Composite Decking Screw accessories designed for secure fixing of keels, clips, and edge caps in outdoor flooring installations. As a trusted supplier of building material fasteners, we offer two high-performance options to meet diverse project needs: corrosion-resistant Stainless Steel Screw for humid/coastal environments and cost-effective Iron Screw for dry-area projects. These Floor Fixing Screw products are engineered to pair seamlessly with WPC decking, ensuring stable, long-lasting installations that resist loosening, corrosion, and deformation. Whether working with wooden joists, WPC joists, or metal joists, our precision-manufactured screws deliver reliable fixing results.
In composite decking projects, the quality of fixing accessories directly impacts overall durability and safety. Our Building Material Screw range addresses the unique demands of outdoor installations—exposure to moisture, temperature changes, and foot traffic—with robust performance. From residential backyard decks to commercial plazas, these screws are the preferred choice for contractors and homeowners, ensuring a tight connection between joists and decking boards that stands the test of time.

Choose Stainless Steel Screw for superior rust resistance in humid, coastal, or outdoor environments, or opt for Iron Screw for budget-friendly projects in dry conditions. Both options offer exceptional strength and reliability, catering to different project budgets and environmental requirements.
Our Composite Decking Screw line includes specialized types for optimal compatibility: Drill Tail Screw for galvanized steel, aluminum, and stainless steel joists, and Self-tapping Screw for WPC joists and wooden joists. This targeted design ensures a tight, secure fit that prevents decking movement.
Each screw features a precision thread design that delivers strong holding power, preventing decking from loosening or deforming over time. Even under heavy foot traffic or environmental stress, the screws maintain stability, extending the decking’s service life.
Our screws come with clear installation instructions, including pre-drilling recommendations. Pre-drilling with a slightly smaller diameter hole ensures smooth penetration without damaging the decking surface, simplifying installation and reducing waste.
Made from high-quality materials, our Durable Decking Screw products resist wear, corrosion, and fatigue. The robust build minimizes replacements and maintenance costs, making them a cost-effective choice for long-term outdoor installations.
Beyond keel and clip fixing, our screws are ideal for installing edge caps, serving as a versatile accessory for complete composite decking projects. This versatility eliminates the need for multiple fastener types, streamlining installation.
We offer a range of sizes to match different decking thicknesses and fixing requirements. Our Precision Screw sizing ensures a perfect fit for both standard and customized decking, enhancing overall installation stability.
Our screws are specifically engineered to pair with WPC decking, ensuring perfect compatibility and performance. This tailored design avoids mismatched fasteners that compromise decking integrity.
We source premium materials for Stainless Steel Screw and Iron Screw products, ensuring resistance to corrosion, wear, and environmental damage. Rigorous material testing guarantees consistent quality across every batch.
Each screw undergoes strict quality checks for precise dimensions, sharp threads, and reliable performance. Our quality control process adheres to international standards, ensuring every product meets high industry benchmarks.
Our team of experts provides technical support, including guidance on screw selection, pre-drilling, and installation techniques. We’re dedicated to helping you achieve a secure, efficient installation.
With over 15 years in the WPC and building materials industry, we understand outdoor installation challenges. Our Composite Decking Screw range reflects this expertise, delivering solutions trusted by contractors worldwide.
The choice depends on joist material. Use Drill Tail Screw for galvanized steel, aluminum, or stainless steel joists. For WPC or wooden joists, select Self-tapping Screw for a secure fit.
Screw size is determined by decking thickness and fixing needs. Thicker decking requires larger screws for adequate holding power. Contact our team for personalized size recommendations.
Yes, pre-drilling is recommended. A slightly smaller hole diameter ensures the screw grips securely without damaging the decking surface.
Avoid over-tightening or under-tightening to prevent decking deformation. Do not use excessively long screws that may penetrate the decking. Ensure screw material matches joist type to avoid corrosion.
