Seamless Structure Pipe - Engineered for Strength, Built for Thailand

As Thailand accelerates its infrastructure development under the Eastern Economic Corridor (EEC) and Thailand 4.0 policy, the demand for high-performance structural materials continues to grow. Our seamless structure pipes are designed to meet these evolving engineering challenges with superior quality, reliability, and cost efficiency.

Manufacturing & StandardsGR.A, GR.B Seamless Structure Pipe
Produced through advanced hot-rolled and cold-drawn processes, our seamless pipes conform to international standards such as ASTM A53, ASTM A106, API 5L, and JIS G3441.

Key Features

● Seamless Integrity - No welded seam means no weak points. Ideal for structural frameworks requiring high impact resistance and fatigue strength.

● Precision Dimensional Tolerances - Uniform outer diameter, wall thickness, and straightness simplify fabrication, reduce waste, and lower installation costs.

● High Load-Bearing Capacity - Excellent yield and tensile strength make these pipes suitable for columns, trusses, and pile foundations.

● Corrosion Protection Options - Available with hot-dip galvanizing, epoxy coating, or FBE lining to withstand Thailand's tropical humid climate and coastal environments in Chonburi, Rayong, and Songkhla.
