 PRODUCT

Tianjin BRISK STEEL focus on produce and supply hollow section and steel pipe

The grade designation carries clear meaning:

• "S" stands for structural steel,

• "355" represents the minimum yield strength of 355MPa,

• "N" indicates normalized heat treatment,

• "L" denotes excellent low-temperature impact performance,

• "H" refers to hollow sections.

• Our S355NLH steel tubes are available in seamless, welded, and ERW forms, manufactured through advanced smelting, rolling, and heat treatment processes, ensuring uniform internal structure, precise dimensions, and outstanding comprehensive performance. They are ideal for structural and industrial applications, especially in low-temperature and harsh environments.

• Yield Strength (Reh): ≥355MPa (for wall thickness ≤16mm), ≥345MPa (for 16mm < wall thickness ≤40mm), ≥335MPa (for 40mm < wall thickness ≤65mm).

• Tensile Strength (Rm): 470-630MPa, ensuring excellent load-bearing capacity and structural stability.

• Elongation (A): ≥22% (longitudinal), ≥20% (transverse), facilitating forming and processing operations.

• Impact Toughness (KV): Minimum 27J at -50℃, meeting the low-temperature impact test requirements of EN 10045-1, making it suitable for cold regions and low-temperature working conditions.

• Heat Treatment: Normalized (N), which refines the grain structure, improves toughness, and reduces internal stress.

• Superior Low-Temperature Performance: Withstand -50℃ low-temperature environment, impact energy ≥27J, suitable for cold regions, polar projects, and low-temperature industrial equipment, effectively avoiding brittle fracture under low-temperature conditions.

   

• Excellent Structural Strength: High yield and tensile strength, uniform grain structure after normalized heat treatment, strong load-bearing capacity, torsion resistance, and bending resistance, reducing material usage and project costs while ensuring structural safety.

   

• Outstanding Weldability: Low carbon content and optimized chemical composition, supporting arc welding, laser welding, submerged arc welding, and other conventional welding methods, with low welding difficulty and no need for preheating or post-weld heat treatment in most scenarios, improving construction efficiency.

   

• Strict Quality Control: From raw material selection (high-purity steel billets) to smelting, rolling, heat treatment, and final inspection, we implement multi-level quality checks, including non-destructive testing (complying with EN 10246-3/5/8), -50℃ impact test, and dimensional inspection, ensuring each batch of products meets EN 10210 standards.

   

• Flexible Customization: Support customization of tube type, size, wall thickness, length, surface treatment, and end treatment to meet the specific needs of different projects and industries, such as super-large diameter tubes for offshore platforms and thick-walled tubes for mechanical equipment.

   

• Full Traceability: Each batch of steel tubes is equipped with product tags and issued with original mill test certificates in EN 10204 format 3.1/3.2, ensuring full traceability of product quality and compliance with international project requirements.

Benefiting from its excellent comprehensive performance, our EN 10210 S355NLH steel tubes are widely used in various high-demand industries worldwide:

• Structural Engineering: High-rise buildings, large-span bridges, steel frames, columns, trusses, power transmission towers, cranes, and sign supports, especially in cold regions such as the Russian Far East and Northern Europe.

• Marine & Offshore Engineering: Offshore oil and gas platforms, marine structure piles, docks, and offshore wind power towers, adapting to harsh marine and low-temperature environments.

• Energy & Industrial Manufacturing: Long-distance oil and gas pipelines, power plant infrastructure, petrochemical plants, chemical plants, fertilizer plants, and machinery manufacturing (crane arm frames, excavator booms, mine dump truck frames).

• Low-Temperature Projects: Arctic LNG storage tanks, cold-region water supply and heating pipelines, and polar expedition equipment, relying on excellent low-temperature toughness to ensure safe operation.
