Product introduction
1. Product Overview
Product Name
HFW Polished Surface ERW Tube 76mm-660mm Decoration Structure Pipe
Core Standard & Product Positioning
This series of HFW high-frequency polished ERW welded tubes adopts dual mature HFW high-frequency welding and ERW electric resistance welding technology, manufactured strictly in accordance with EN 10219, ASTM A53 and national architectural decoration steel pipe standards. Covering complete outer diameter specifications from 76mm to 660mm, it is a professional dual-functional steel pipe integratingarchitectural decorative aesthetics and structural load-bearing performance. Different from ordinary industrial black pipes, this product undergoes multi-stage fine polishing treatment on the pipe surface, with no welding trace, uniform gloss, smooth and flawless surface. It perfectly balances beautiful decorative effect and stable structural strength, widely applicable to indoor and outdoor architectural decoration, building structural support, landscape engineering and commercial space decoration projects.
Core Decoration & Structural Advantages
Aiming at the dual requirements of modern architectural projects for "aesthetic decoration and safe structure", our polished HFW/ERW tube solves the pain points of ordinary welded pipes such as rough surface, obvious welding marks, easy rust and poor appearance. With precise welding forming and professional fine polishing process, the pipe body features straight lines, uniform surface gloss, easy cleaning and long-term non-fading. Meanwhile, it retains excellent mechanical properties of welded steel pipes, with stable load-bearing capacity and strong structural rigidity, realizing one-pipe dual-use of decoration and support, greatly simplifying project construction and reducing comprehensive engineering cost.
