Company Profile
Shandong Ruifenglian Supply Chain Co., Ltd. upholds the corporate culture of "Integrity, Enterprising, Diligence, and Efficiency," operating under a flexible modern enterprise system. Leveraging our talent and capital advantages, we have established stable and sound cooperative relationships with well-known domestic manufacturers. Backed by years of professional international trade experience, we are committed to delivering premium products and all-round reliable services to global clients.
We specialize in exporting high-corrosion-resistant coated metal products, covering three core business categories: steel products, thermal insulation materials, and cable tray series. Our goods are exported to over 20 countries and regions across Africa, America, Southeast Asia, Central Asia, and beyond.
Integrated Manufacturing & Trading for Cable Trays
In the cable tray sector, we operate an integrated manufacturing-and-trading model. We maintain our own supporting processing facility, offering full-chain service capabilities from raw material sourcing to specialized production and export trading. Our cable trays are manufactured in-house using premium galvanized, galvalume, and pre-painted steel raw materials sourced from qualified suppliers. Our product range includes ladder-type, trough-type, perforated, and solid-bottom cable trays, widely applied in power engineering, photovoltaic projects, factory workshops, commercial construction, electrical control systems, and municipal infrastructure.
Advanced Manufacturing with Premium Raw Materials
Our cable trays are manufactured using premium-grade hot-rolled steel coils sourced from top-tier domestic steel mills including Tianjin Xintian Steel, Tianjin Xinyu, and Hebei Yanbo, ensuring consistent material quality and mechanical properties. All raw materials undergo rigorous incoming inspection for thickness tolerance, tensile strength, and surface finish before entering production.
Surface treatment strictly follows international standards: hot-dip galvanizing achieves a zinc coating thickness of 65–85 μm, providing exceptional corrosion resistance for harsh environments. For extreme conditions, we offer galvalume (Al-Zn) coating up to 275 g/m² and pre-painted finishes with color options to match project requirements.
Production is powered by state-of-the-art CNC punching presses, automated roll-forming lines, and hydraulic bending equipment, enabling precision manufacturing with tight tolerances, high output capacity, and flexible customization for non-standard sizes and special configurations.
Featuring strong anti-rust performance, high structural strength, easy installation, and fully customizable specifications, our cable trays perfectly match our coated steel coils and sheets to form a complete supporting metal product supply system for engineering projects.
We adopt a customer-centric operation philosophy, taking high-quality products and professional services as our core competitiveness. Supplier management and supervision sit at the heart of our quality control system. Every batch of raw materials and finished products undergoes strict in-house inspection during production to fully implement standardized quality management protocols.
Core Advantages
Unlike pure traders or single-product manufacturers in the industry, we have achieved an integrated manufacturing-and-trading model for cable trays — combining our own processing facility with a professional international trade team to serve global customers. We carefully select raw material plates from quality suppliers and conduct specialized production in our own facility, effectively cutting intermediate circulation costs and shortening the delivery cycle of complete sets of engineering materials.
We provide customers with one-stop supporting solutions including steel coils, color steel sheets, corrugated panels, and matching cable trays, greatly simplifying procurement procedures and reducing coordination costs across multiple suppliers. Whether customers need small-batch trial orders or large-scale bulk engineering supplies, we can flexibly adjust production schedules to match their construction progress and project timelines.
