Grades, Standards and GOST Equivalents
Equal angles are supplied to ASTM A36, EN 10056 (S235JR-S355JR), GB 9787 (Q235, Q345) and GOST 8509 (St3, 09G2S). For the Russian market GOST 8509 is the governing standard, with St3 for general structures and 09G2S for low-temperature service, and we prepare certificates cross-referencing the international grade. Sizes from 20x20x3 to 200x200x20 mm in 6 m and 12 m lengths, black or hot-dip galvanized per ISO 1461. The combination of grade, size and certification makes direct mill supply valuable for structural steel suppliers and fabricators across the EAEU.
Manufacturing Process
Equal angle steel is produced by hot rolling: billets are reheated and rolled through a series of passes on a section mill, forming the two equal legs with a sharp or rounded corner, then cooled on a cooling bed, straightened and cut to length. Angles from 20x20x3 to 200x200x20 mm are supplied in 6 m and 12 m lengths, in Q235, Q345, A36, S275 and S355 grades. The rolling process controls the leg dimensions, thickness and corner radius within the tolerances of GB 9787, EN 10056 or GOST 8509. Galvanized angles are hot-dip coated per ISO 1461 after rolling for outdoor service. Each batch is tested for chemical composition and mechanical properties (yield, tensile, elongation), with the MTC issued per EN 10204 3.1 and GOST 8509 cross-reference for the Russian market.
Applications
- Steel structures and frames
- Brackets, supports and bracing
- Towers, masts and transmission structures
- Machinery bases and frames
- Fencing and gates
Applications in Steel Structures and Industry
Equal angle steel is the most widely used section in light and medium steel structures. Fabricators use angles for frames, bracing, brackets and supports in industrial buildings, mezzanines and equipment. Transmission tower and mast manufacturers consume angles in large volumes for lattice structures. The solar mounting sector uses galvanized angles for support structures, where the HDG coating ensures long service life. Machinery builders use angles for equipment frames and bases. In the agricultural sector, angles form the frames of greenhouses, livestock buildings and storage facilities. With the GOST 8509 grade mapping, Russian and Kazakh fabricators can source angles directly for projects designed to domestic standards, including 09G2S for cold-climate structures.
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
Angles are packed in bundles with steel strapping and dunnage, labeled with the standard, grade, size, length and weight. Bundles of 6 m or 12 m lengths are loaded into containers with a calculated stowage plan; longer sections ship in flat racks or open-top containers. Galvanized angles are packed with surface protection. The documentation – MTC per EN 10204 3.1 with GOST 8509 cross-reference, ST-1 certificate, invoice and packing list – is prepared for EAEU customs clearance.
The Angle Market in Russia and Central Asia
Equal angle steel is a staple of the structural steel trade in Russia and Central Asia. Steel service centers stock angles as a core product for fabricators, and construction of industrial buildings, logistics centers and agricultural facilities drives steady demand. The solar mounting sector in Kazakhstan and Uzbekistan adds demand for galvanized angles. Transmission and tower construction consumes large angles in project volumes. Because domestic section mills focus on standard sizes, the market for galvanized angles, 09G2S grade and specific sizes is partly supplied by imports. Sino East Steel supplies angles directly to service centers, fabricators and solar EPC contractors across the EAEU.
How to Choose the Right Equal Angle
Select the size by the structural load: 20-40 mm for light brackets and trim, 50-63 mm for general frames and bracing, 100 mm+ for heavy structures and towers. Choose the grade by the design temperature: Q235/A36/St3 for general service, Q345/S355 for higher loads with lower weight, 09G2S for welded structures in cold climates. For outdoor and solar mounting applications specify hot-dip galvanized angles per ISO 1461. Confirm the length (6 m or 12 m) and the certificate format with your fabricator. For Russian projects confirm the GOST 8509 cross-reference in the MTC.
