The Philippine construction industry relies heavily on tubular steel for frameworks, scaffolding, and structural support. With rising material costs in 2025 due to global supply chain shifts, contractors and builders need up-to-date pricing to budget effectively. In this blog post, you will learn about the latest tubular steel price list for the year 2025.
What is Tubular Steel?
Tubular steel is a hollow, cylindrical, or rectangular metal profile made from carbon steel, stainless steel, or galvanized iron (GI). It is widely used in construction, manufacturing, and engineering due to its high strength-to-weight ratio, durability, and versatility. Unlike solid steel bars, tubular steel’s hollow structure makes it lighter yet strong, ideal for structural frameworks, scaffolding, and mechanical applications.
Types of Tubular Steel
Galvanized Iron (GI) Pipes – Coated with zinc to resist rust, commonly used in fencing, handrails, and light structural supports.
Black Iron Pipes – Uncoated carbon steel, often used in plumbing, gas lines, and industrial machinery due to its high-pressure resistance.
Stainless Steel Tubes (304 & 316L) – Corrosion-resistant, perfect for coastal buildings, food processing plants, and medical equipment.
Structural Steel Tubes (ASTM A500) – High-strength for bridges, high-rise buildings, and heavy-load structures.
Electric Resistance Welded (ERW) Pipes – Cost-effective for scaffolding, automotive frames, and furniture.
Seamless Steel Pipes – Used in high-pressure applications like oil pipelines and hydraulic systems.
Key Uses of Tubular Steel
Construction: Primary material for beams, columns, and roofing trusses due to its load-bearing capacity.
Scaffolding: Lightweight yet sturdy, making it ideal for temporary work platforms.
Plumbing & Gas Lines: Black iron and stainless steel tubes ensure leak-proof and durable piping systems.
Automotive & Aerospace: Used in chassis, roll cages, and aircraft frames for high strength without excess weight.
Furniture & Design: Modern steel-framed tables, chairs, and decorative structures rely on tubular steel for sleek aesthetics.
Why is Tubular Steel Important?
Cost-Effective Strength – Provides higher structural integrity than wood or concrete at a lower weight.
Corrosion Resistance – Galvanized and stainless steel variants last decades even in harsh environments.
Design Flexibility – Can be welded, bent, and fabricated into complex shapes for custom projects.
Sustainability – 100% recyclable, reducing environmental impact compared to other materials.
