Frequently Asked Questions

What types of steel do you use for custom fabrication?

We use a range of steel materials depending on the application, including Q235, Q355, and stainless steel, with options for hot-dip galvanized or zinc-aluminum-magnesium coating. For coastal and high-corrosion environments, we recommend advanced weathering steel. Our engineering team can advise on the best material selection for your project, considering factors such as load-bearing requirements, environmental exposure, and budget. We source from certified suppliers to ensure traceability and consistent quality, and we can provide material certifications upon request.
Quality is at the core of our fabrication process. We implement a multi-stage quality control system, starting with incoming material inspection, then in-process checks during cutting, welding, and finishing, and finally a comprehensive final inspection before packing. Our QC team uses advanced measurement tools to verify dimensional accuracy and weld integrity. We also conduct load tests and salt spray tests on samples to validate durability. All our products are manufactured in accordance with ISO 9001 standards, and we can provide detailed inspection reports and certifications with every shipment.
Yes, we offer comprehensive OEM services, including product design, prototyping, and mass production with your branding and packaging. We work as an extension of your manufacturing capabilities, handling the entire production cycle while maintaining strict confidentiality. Our engineering team can modify existing designs or create new ones based on your specifications. We also offer private labeling, custom packaging, and documentation to meet your market’s requirements. This flexibility allows you to offer high-quality custom steel fabrication without investing in your own production facilities.
Lead times vary based on the complexity and quantity of the order. For standard products, we typically ship within 15-25 days. For custom fabrication, the lead time includes design and prototyping, usually adding 5-10 days. Our large manufacturing capacity and efficient processes help minimize delays. We provide a clear production schedule and keep you updated throughout the process. For urgent projects, we can offer expedited services at an additional cost. We always aim to balance speed with quality to meet your project deadlines.
We have extensive experience with international shipping, managing all export documentation, including commercial invoices, packing lists, and certificates of origin. We work with reliable freight forwarders to offer the most cost-effective and efficient shipping methods—sea, air, or rail—depending on your location and timeline. We can also handle DDP (Delivered Duty Paid) terms, ensuring a seamless door-to-door experience. Our team stays informed about customs regulations in different countries, minimizing the risk of clearance issues. We also provide robust packing to protect products during transit, ensuring they arrive in perfect condition.
