Rectangular Steel Tube EN 10219 – Specifications

Grades, Standards and GOST Equivalents

Hollow sections are supplied to ASTM A500 Grade B/C, EN 10219 (S235-S355), GB/T 6728 and GOST 30245. For the Russian market GOST 30245 is the governing standard for square and rectangular profile pipes, with steel grades St3, St4 and the low-alloy 09G2S for cold-climate construction. We cross-reference the international grade with the GOST equivalent in the certificate, so structural steel suppliers and construction companies in the EAEU can use the batch without additional testing. Galvanized sections are produced pre-galvanized (from galvanized coil) or hot-dip galvanized per ISO 1461 with zinc 170-350 g/m2, and 09G2S grade is available for projects designed to Russian SNIP codes where low-temperature toughness is mandatory.

Manufacturing Process

Square and rectangular hollow sections are produced on cold-forming lines: hot-rolled or cold-rolled coil is slit to width, formed progressively into a closed section on a cold roll-forming mill, and welded with a high-frequency ERW weld along the longitudinal seam. The weld is then annealed and the tube is passed through sizing and straightening stands that set the exact outer dimensions and corner radii. Cold forming gives the tube precise dimensions, a smooth surface and consistent wall thickness, which is why hollow sections are preferred for visible structures and precision fabrication. We supply sections from 20×20 mm to 200×200 mm square and up to 200×100 mm rectangular, with wall thicknesses from 1.0 to 12 mm, in 6 m and 12 m lengths, in black, pre-galvanized or hot-dip galvanized finish. Each batch is tested for yield strength, tensile strength, elongation and weld integrity, with the MTC issued per EN 10204 3.1.

Applications

• Structural frames for buildings and industrial halls
• Trailers, trucks and agricultural machinery
• Racks and storage systems
• Fences, gates and solar mounting structures
• Furniture and interior design

Applications in Russia and Central Asia

Hollow sections are the most versatile structural product in the regional market. Steel fabricators use square and rectangular tubes for the frames of industrial buildings, mezzanines, racks and storage systems, taking advantage of the high strength-to-weight ratio and the clean appearance of cold-formed sections. Trailer and agricultural machinery manufacturers specify rectangular tubes for chassis and equipment frames. The solar energy sector – growing rapidly in Kazakhstan and Uzbekistan – uses pre-galvanized square tubes for mounting structures, where the zinc coating guarantees 20+ years of outdoor service. Fencing, gates, handrails and architectural elements complete the picture, and the 09G2S grade extends the application range to structures designed for Siberian winters.

Quality Control and Testing

Every production stage at the Sino East Steel plant is controlled under an ISO 9001:2015 quality management system. Depending on the product, each batch is tested for chemical composition and mechanical properties (yield strength, tensile strength, elongation), dimensional accuracy, surface quality and, where applicable, hydrostatic pressure, weld seam integrity, zinc coating thickness and paint adhesion. All testing is performed in our laboratory and, when the project requires, witnessed by independent inspectors from SGS, Bureau Veritas or TUV Rheinland. Each shipment is accompanied by a Mill Test Certificate (MTC) per EN 10204 3.1 with heat numbers, so every tonne can be traced back to its production date, heat and chemical analysis. This documentation is prepared in a form accepted by customs authorities in Russia, Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, Turkmenistan and Belarus, and can be adapted to GOST-based reporting when the buyer’s quality department requires it.

Documents and Compliance for Russia and the EAEU

All goods are supplied with a complete export documentation set prepared for smooth customs clearance in the Russian Federation and the Eurasian Economic Union: Mill Test Certificate (MTC) per EN 10204 3.1 with heat numbers and chemical analysis, Certificate of Origin form ST-1 (which qualifies for duty-free import within the EAEU), commercial invoice, packing list and bill of lading or railway consignment note. Where the project is subject to the EAEU Technical Regulations, we support the EAC certification process and provide the technical passport, test reports and conformity documentation required by the importing party. For products supplied against Russian design standards we prepare documentation referencing the relevant GOST equivalents (for example GOST 3262 for galvanized pipe, GOST 8732 for seamless pipe, GOST 30245 for hollow sections), so your quality department and the customs broker receive everything on the day the vessel or train arrives.

Logistics to Russia and Central Asia

Sea freight from Tianjin and Xingang ports to St. Petersburg, Novorossiysk, Vladivostok and the Baltic ports takes 30-45 days, with container and break-bulk options for project volumes. For Central Asia we ship container rail trains via the Dostyk and Khorgos border crossings to Almaty, Astana, Tashkent, Samarkand, Bishkek, Osh, Dushanbe and Ashgabat in 25-40 days. We quote on FOB Tianjin/Xingang, CFR, CIF, or DAP terms to your warehouse, consolidate several product lines in one container to reduce the freight cost per tonne, and agree the shipment schedule with your project calendar. A Russian-speaking sales team follows your order from specification to customs clearance, prepares the transit documentation for rail corridors, and coordinates with your forwarding agent at the destination. For regular buyers we offer scheduled programs with fixed prices for the contract period, protecting your project budget from market volatility.

Packaging and Loading

Hollow sections are packed in bundles with steel strapping and dunnage, labeled with standard, grade, section size, wall thickness and length. Standard bundles of 6 m or 12 m sections are loaded into containers with a calculated stowage plan per size, and bundles are stacked with separators to protect the corners and the galvanized surface. Pre-galvanized tubes are packed with surface protection to prevent scratching during transit. Each shipment is documented with the MTC, ST-1 certificate, invoice and packing list, prepared for customs clearance at the destination port or border crossing.

The Russian and Central Asian Market for Hollow Sections

Demand for square and rectangular tubes in the region tracks construction, machinery and the fast-growing solar sector. Russian steel service centers stock hollow sections as a core product for fabricators, and the construction of logistics centers, warehouses and industrial parks consumes large volumes of 80×80 to 150×150 sections. Kazakhstan and Uzbekistan are among the fastest-growing solar markets in the region, and pre-galvanized square tubes for solar mounting are a significant import category. The trailer and agricultural equipment industries in Russia and Belarus also consume rectangular tubes in substantial volumes. Sino East Steel supplies hollow sections directly to steel distributors, solar EPC contractors and machinery builders across the EAEU, with the grade range – including 09G2S – that regional projects require.

How to Choose the Right Hollow Section

Select the section size and wall thickness by the structural load: for frames and racks, 40×40 to 80×80 with 2-4 mm wall covers most applications; for columns and heavy equipment frames, use 100×100 to 200×200 with 6-12 mm wall. For outdoor structures and solar mounting, choose pre-galvanized (economical) or hot-dip galvanized (thicker coating, longer life). For Russian projects specify 09G2S or confirm the grade mapping from EN 10219 S355, because low-temperature toughness is required by SNIP design codes. Confirm whether the project needs cut-to-length or standard 6/12 m lengths, and whether the tube will be welded (carbon equivalent matters) or mechanically joined. We provide the certification with GOST 30245 cross-reference so the batch is accepted without additional testing.

Why Buy Hollow Sections Direct from the Factory
