Hot Rolled Q235B ERW Welded Carbon H Beam For Structural Steel Pipes
YTDR Group is a premier international supplier of structural steel piping solutions, providing engineered steel products for critical infrastructure and heavy construction applications. We specialize in supplying high-grade H Beam sections and structural pipes to engineering contractors, procurement firms, and distributors engaged in large-scale bridge, high-rise, and industrial plant projects across Europe, the Middle East, and North America.
The following product specification details our Hot Rolled Q235B ERW Welded Carbon H Beam, optimized for structural integrity and compliance with international engineering standards.
1. Quantified Hard Indicators for Overseas Clients
● Material: Q235B carbon structural steel, with yield strength ≥235MPa, tensile strength 375-500MPa, elongation ≥26%, and impact energy ≥27J (20℃). It features excellent mechanical stability and welding compatibility, suitable for various structural load-bearing requirements.
●Specification: Section height 100-900mm, flange width 68-300mm, web thickness 4.5-14mm, flange thickness 7.6-18mm, length 6-12m (custom extra-long sizes available), theoretical weight 17.2-294.5kg/m.
● Process: Hot Rolled forming + Electric Resistance Welded (ERW) technology. The welding temperature is controlled at 1100-1250℃, with online flaw detection testing applied, ensuring a weld qualification rate of 99.9% and structural integrity.
● Standard: Complies with GB/T 11263-2017 (Chinese standard), ASTM A36 (American standard), and EN 10025-2 (European standard), meeting the structural steel application specifications of mainstream global markets.
● Surface Treatment: Default Pickling Passivation and Sand Blasting; optional Hot Dip Galvanizing (zinc layer thickness ≥85μm) and 3PE anti-corrosion coating to enhance weather resistance and service life.
(1) Data & Test Results to Solve Industry Pain Points
● Corrosion Resistance: After neutral salt spray testing, products treated with 3PE anti-corrosion coating maintain corrosion resistance for over 1000 hours without obvious rust. Suitable for humid and corrosive environments such as marine climates and industrial plants, extending service life by 3-5 times compared to ordinary carbon steel components.
● Pressure and Load-Bearing Capacity: After hot-rolled forming, Q235B material achieves a 20% improvement in overall compressive strength. The web and flange are tightly bonded, capable of withstanding a uniform load of ≥25kN/m². Passed third-party load testing with no deformation or cracking, suitable for large-span building structure requirements.
● Precision Control: Equipped with CNC forming equipment, the section dimension tolerance is controlled within ±0.5mm, straightness error ≤3mm/10m, and weld seam flatness ≤0.3mm. It can be directly assembled without secondary processing, reducing customers' construction costs.
(2) Core Trust Endorsements for Foreign Trade
● Our H Beam structural steel pipes have obtained a full set of international certifications to meet the access requirements of global markets:
● API 5L (for structural applications in oil and gas pipeline auxiliary projects)
● CE Certification (compliant with EU Construction Products Regulation (CPR), enabling free circulation in the EU market)
● ISO 9001:2015 Quality Management System Certification (covering the entire production process from raw material procurement to delivery)
● SGS/BV Third-Party Inspection Reports (available for every batch of goods, with customizable inspection items at the buyer’s request)
● CO Certificate of Origin (issued by the Chamber of Commerce, supporting preferential tariff policies in target markets)
Relying on the group's flexible production lines, we meet various non-standard needs and improve cooperation adaptability:
● Specification Customization: Supports customization of special wall thickness (15-25mm), non-standard section sizes (e.g., special-shaped H-beams), and extra-long components (12-18m). Minimum order quantity is 50 tons, with sample prototyping completed within 7 days.
● Surface Treatment Customization: In addition to conventional processes, custom 3PE/2PE anti-corrosion coating and coal tar epoxy coating are available, suitable for special scenarios such as underground pipelines and marine engineering.
● Connection Method Customization: Provides thread processing, flange connection, and beveling services to match customers' existing construction processes and reduce on-site assembly difficulty.
● Packaging Customization: Adopts export-standard fumigated wooden cases fixed with steel strips or pallet packaging. The protection level meets maritime moisture and collision resistance requirements, and shipping marks can be marked according to customer needs.
YTDR Group strictly adheres to global foreign trade compliance standards and has obtained a full set of authoritative certifications to provide solid trust endorsement for cross-border cooperation: API 5L (suitable for oil and gas transportation scenarios), CE Certification (a must for EU market access), ISO 9001 Quality Management System Certification (full-process quality control), SGS/BV Third-Party Test Report (available with goods on request), and Certificate of Origin (CO) (enjoy preferential tariffs in target markets). All products pass customs inspection and local market sampling inspection.
