Pinghu Hengke Metal Products Factory, a professional fastener manufacturer and exporter based in Jiaxing (near Shanghai, Zhapu, and Ningbo ports), specializes in chipboard screws for outdoor use—engineered to withstand the harsh conditions of outdoor woodworking projects, such as rain, UV radiation, temperature fluctuations, and moisture. Our chipboard screws for outdoor use are made from corrosion-resistant materials, including 304 or 316 stainless steel, or undergo heavy-duty galvanization (hot-dip zinc coating) to prevent rust, oxidation, and degradation caused by outdoor elements. The design of our chipboard screws for outdoor use also focuses on weather resistance: the threads are treated to resist debris buildup, and the heads are sealed to prevent water penetration into the screw core, ensuring long-term holding power in outdoor wood materials like pressure-treated lumber, cedar, or chipboard used for garden sheds, outdoor furniture, or wooden fences. Each chipboard screw for outdoor use undergoes rigorous testing, including UV exposure tests and temperature cycle tests, to confirm it maintains its strength and stability in extreme weather. We offer various lengths and diameters of chipboard screws for outdoor use, matching different wood thicknesses and project requirements, and provide technical support to help clients select the right screw for specific outdoor applications. Guided by our "product quality first" concept, we export chipboard screws for outdoor use to Europe, the United States, and beyond, delivering a reliable fastener solution that ensures outdoor wood projects remain secure and durable for years.
