Unlike standard electro-galvanising, our Hot Dip manufacturing process immerses the steel directly into molten zinc, creating a tightly bonded alloy layer (Z81-Z120). This ensures deep penetration and uniform coverage inside and outside the pipe, preventing rust even in extreme maritime or underground industrial applications.
To ensure the pipes arrive at your facility in pristine condition, we offer customizable protective wrapping, including inter-layer paper and durable PVC surface films to prevent mechanical abrasion during ocean transit.
Our galvanised round and square tubes form the structural and operational backbone for numerous sectors:
Construction & Infrastructure: Scaffolding frameworks, structural columns, and highway guardrails.
Fluid Transmission: Low-pressure liquid delivery, water supply systems, and industrial HVAC piping.
Energy & Petrochemical: API-compliant tubes for specialised industrial gas and oil transport requirements.
As a primary manufacturer in China, we facilitate scalable metal supply chains for global steel wholesalers, EPC contractors, and structural fabricators. Please submit your required material grade (e.g., ASTM A53), shape profile, exact dimensions (OD × Thickness × Length), and total project tonnage to receive an official factory-direct price and MOQ details.
