As a China-based manufacturer located in Shanghai, Lingyufab leverages the region's robust supply chain and skilled workforce to produce high-quality metal frames and structures at competitive prices. We adhere to ISO 9001:2015 quality management system. Our in-house production eliminates outsourcing costs, delivering 15 to 20 percent cost savings to customers. We support 1-piece samples, 100-piece pilot runs, and high-volume mass production with monthly output exceeding 5,000 units.

Our metal frames and structures are engineered to precise specifications.

Lingyufab specializes in producing custom metal frame and structure parts including:

Each part is tailored to your specific load requirements, equipment configuration, and facility layout. Our engineering team provides upfront technical support, including structural analysis, design optimization, and cost-reduction recommendations. We support reverse engineering services. If you have a physical sample without drawings, we can 3D scan, model, and generate production-ready engineering prints. Whether you need a single prototype or thousands of units, we deliver consistent quality with zero MOQ for prototyping stages.

What truly sets Lingyufab apart is our ability to integrate the full spectrum of sheet metal processes, including laser cutting, CNC bending, stamping, welding, and surface treatment, into a seamless manufacturing workflow for metal frames and structures. Rather than outsourcing individual steps to multiple vendors, we manage everything in-house, ensuring tighter quality control, faster lead times, and consistent communication throughout the entire production cycle. With our in-house fastener manufacturing, we can pre-install mounting brackets, connection plates, and assembly hardware directly onto your frames and structures, eliminating external sourcing and reducing assembly time on your end. The result is a streamlined, cost-effective solution that provides reliable structural integrity and long-term performance in demanding industrial environments.

A metal frame is a structural assembly of metal components—such as beams, columns, channels, and brackets—that provides support, shape, and stability to equipment, machinery, or buildings. A metal structure is a larger system of interconnected frames designed to bear loads and resist forces. Together, they form the backbone of industrial equipment, automation systems, and facility infrastructure, ensuring strength and durability across demanding applications.

Lingyufab supports 1-piece prototyping, 100-piece pilot runs, and high-volume mass production with monthly delivery exceeding 5,000 units.

When designing and fabricating metal frames and structures, consider the following guidelines:

Wall thickness typically ranges from 1.5mm to 12.0mm depending on load requirements. Profile sizes vary based on structural needs.

Precision is critical for metal frames and structures to ensure proper fit, alignment, and load distribution. Lingyufab maintains the following accuracy standards:

These standards are maintained through advanced laser cutting, CNC bending, and welding equipment, combined with rigorous in-process inspection and final quality control checks.

Lingyufab implements a comprehensive quality control system for metal frames and structures:

Metal frames and structures can be fabricated into various configurations to suit different applications:
