High-quality raw materials are sourced from trusted suppliers. Our QC team inspects composition, strength, and consistency before production. Only qualified materials are used, ensuring the fittings meet durability and corrosion resistance standards from the very beginning of manufacturing.
Production involves multiple steps including casting, finishing, surface treatment, and inspections. Each stage is carefully monitored by our technicians. We combine advanced automation with manual precision to ensure every fitting meets required specifications and performs reliably in railing systems.
Using sand mold technology, molten iron is poured into pre-designed molds to form the basic structure of the elbow. Cooling and solidification processes are controlled strictly to ensure accuracy, strength, and the required adjustable angle of the product.
After casting, the fittings undergo cutting, grinding, and shot blasting to remove excess material and improve surface smoothness. These processes enhance dimensional precision, ensure socket accuracy, and prepare the fittings for subsequent coating treatments and quality inspections.
During finishing, dimensional inspections and strength tests are conducted to verify accuracy. Our QA team identifies any defects early, ensuring only qualified semi-finished products proceed to the next stage. This guarantees consistency and minimizes the risk of performance issues.
The fittings are treated with hot-dip galvanizing, double galvanizing, or powder coating. Each process enhances corrosion resistance and surface durability. Customers can choose finishes depending on environmental requirements, ensuring the elbow fits both indoor and outdoor railing applications.
After surface treatment, another round of inspections checks coating thickness, adhesion, and uniformity. Mechanical properties are also tested. This ensures the final fittings meet customer requirements for corrosion resistance, durability, and strength before packaging and shipment.
Fittings are carefully packed using protective materials and customized packaging options. Labels and quantity checks are performed to match orders accurately. With reliable logistics partners, we ensure safe, efficient delivery to global destinations within the agreed schedule.
