Frequently Asked Questions
Pre-galvanized steel pipe is coated with zinc before the pipe is formed or fabricated, ensuring a consistent zinc layer across the entire surface including edges. Hot-dip galvanizing is applied after fabrication by immersing the finished pipe in molten zinc, which may result in uneven coating at weld seams or cut areas. Pre-galvanizing provides more uniform protection and is generally more cost-effective for standard structural applications.
Yuantai offers an extensive size range: square pipes from 10×10×0.5mm up to 1000×1000×60mm, rectangular pipes from 10×15×0.5mm up to 800×1200×60mm, and circular pipes with diameters from Ø10.3mm to 2032mm. Wall thickness options range from 0.5mm to 80mm. Custom sizes can also be arranged upon request.
Yuantai Pre Galvanized Steel Pipes are manufactured to meet or exceed major international standards including ASTM, EN, BS, JIS, and GB standards. Each batch undergoes rigorous quality testing covering dimensional accuracy, mechanical properties, chemical composition, and corrosion resistance to ensure full compliance.
Pre-galvanized steel pipes are widely used in construction (structural frames, scaffolding, greenhouses), infrastructure (fencing, handrails, road barriers), agriculture (irrigation systems, livestock enclosures), and various industrial applications. Their superior corrosion resistance makes them ideal for both indoor and outdoor environments exposed to moisture or harsh conditions.
All raw steel materials used by Yuantai Derun are sourced exclusively from premier state-owned mills, including HBIS, Baosteel, and TPCO. This ensures consistent base material quality and guarantees that every finished pipe meets the highest performance standards before leaving our facility.
