Custom Drawing Contract Fabrication
Custom Drawing Contract Fabrication
Custom drawing contract fabrication is our core service - you send drawings, we manufacture to specification. At Qingdao Tianhua Yihe Metal Fabrication (qdthyhmetalfab.com), we've spent 20 years perfecting the art of turning drawings into finished steel products. Whether you need a single prototype or a production run of thousands, our full-process manufacturing capability covers every step from material procurement through final packaging. Send us your drawings in STEP, DWG, DXF, or PDF format and receive a detailed quote within 2 hours.

Industries We Serve
Our contract fabrication service supports OEMs and engineering companies across construction, mining, agriculture, renewable energy, marine, and industrial equipment sectors. Typical projects include structural steel components for building frames, wear parts for mining equipment, mounting systems for solar farms, and machinery frames for industrial automation. If your product contains steel, stainless steel, or aluminum parts manufactured from drawings, we can produce them - from a single prototype to full production runs.
DFM (Design for Manufacturability) Support
Before production, our engineering team reviews every drawing and provides free DFM feedback: bend radius feasibility, hole-to-edge distance, material grade recommendations, and coating selection. This review prevents costly rework and often reduces part cost without compromising function. Drawing review typically takes 2-4 hours and is included in every quote.
Manufacturing Capabilities
Our contract fabrication service combines all manufacturing processes under one roof: material cutting (laser, plasma, flame, saw), forming (press brake, rolling, stamping), welding (robotic MIG, manual TIG, SAW, spot), machining (CNC turn, mill, drill, grind), surface treatment (HDG, powder coat, epoxy, plating), and assembly. This integrated approach means we control quality at every step and eliminate the coordination overhead of multiple suppliers. For prototype orders, turnaround is typically 2-3 weeks; for volume orders, we schedule production in batches against your delivery milestones.
Quality Assurance
Drawing review and DFM feedback provided on every order before production
First-article inspection with dimensional report before volume production
In-process QC at cutting, forming, welding, and coating stages
Material test certificates (MTC) provided with every shipment
ISO 9001:2015 certified quality management system
Frequently Asked Questions
Q: What drawing formats do you accept?
A: We accept STEP, IGES, DWG, DXF, PDF, SolidWorks, and even hand sketches with dimensions. For complex parts, 3D models (STEP/IGES) are preferred.
Q: What is your minimum order quantity?
A: There is no fixed MOQ. We accept orders from 1 piece (prototype) to 10,000+ pieces. Price per unit naturally decreases with volume.
Q: How quickly can you quote?
A: We provide a detailed quote within 2 hours of receiving your drawings and requirements, including price, lead time, and technical suggestions.
