FAQ As a global supply chain service provider with operations in over 30 countries and regions, our comprehensive product range—encompassing pipes, fittings, valves, and fire-fighting equipment—has obtained ISO international quality certification and complies with multiple regional standards, including CE, UL, and SASO. These products have been successfully implemented in various international scenarios, such as infrastructure projects in Southeast Asia, commercial complexes in the Middle East, and fire renovation projects in Eastern Europe. For both regular procurement and cross-border customization, we offer an integrated solution that spans product selection, customs clearance, and logistics management.
Absolutely. For overseas customization requests, our engineering team collaborates directly with international blueprints and technical specifications to provide multi-standard compatible designs, including wall thickness conversion and pressure grade adaptation. Additionally, we provide:
- Third-party testing reports for pre-production samples
- Packaging labels compliant with the destination country's regulations
- Bilingual technical documentation and compliance certificates to ensure smooth local acceptance
We enforce a global quality control system that surpasses national standards. Each batch undergoes rigorous testing, including raw material composition analysis, pressure burst tests, and salt spray corrosion resistance evaluations, accompanied by bilingual (Chinese-English) quality inspection reports. Based on project location requirements, we can furnish free certification documents for target markets, such as CE (European Union), UL (United States), and BIS (India). Furthermore, we support on-site inspections and remote video audits to ensure full transparency in the quality control process.
The standard delivery cycle for overseas orders ranges from 25 to 45 working days. We offer diverse shipping options, including full container loads, less-than-container loads, and air freight express services.

For warranty-related quality issues, we cover basic shipping costs from Chinese ports or airports to the destination port. Additionally, we provide remote technical guidance, bilingual materials, and coordinate online support with engineers when necessary.
Absolutely. As a one-stop supplier, we specialize in customizing products to match your unique project needs:
Customizable parameters: Pipe diameter (DN15-DN2000), valve pressure rating (PN10-PN400), material (304/316 stainless steel, carbon steel, galvanized steel);
Fire system customization: We collaborate with your engineers to design integrated systems (e.g., high-rise building fire pipelines + matching valves + sprinklers) and provide 2D/3D drawings for confirmation before production.
Sample production is available for testing prior to mass orders.
