As a factory-direct supplier, we produce equal angle steel, unequal angle steel, galvanized angles, and stainless steel angles on our own rolling and processing lines, selling straight from the mill with no middlemen and no trading margins. Our export team has delivered angle steel to buyers in more than 80 countries across Asia, Africa, Europe, the Middle East, and the Americas. Stock sizes are available from a minimum order of just 5 tons, custom production starts at 20 tons, and standard delivery takes 15–30 days from Tianjin Xingang Port.
Steel angle is one of the most widely used structural sections in the world, valued for its strength-to-weight ratio, simple bolting or welding, and exceptional versatility. Our angle bar is rolled in grades Q235, Q345, SS400, and S235JR, with equal legs from 20×20×3 mm up to 200×200×24 mm, unequal legs such as 75×50 mm, and standard lengths of 6 m and 12 m. Our annual production capacity for angles and sections exceeds 100,000 tons, and every batch is traceable from raw billet to finished bundle. Whether your project follows ASTM A36, EN 10056, GB/T 706, or JIS G3192, we supply consistent, certified angle steel at wholesale factory prices.
Why Choose Sino East Steel Group as Your Steel Angle Supplier?
Contractors, fabricators, and distributors choose Sino East Steel Group as their angle steel supplier because we deliver the two things that matter most in structural steel: certified material and reliable supply. Our factory has exported steel sections since 2008, and our production planning, inspection, and documentation systems are built around the needs of international buyers. Here is what you can expect on every angle order.
1. Factory-Direct Manufacturing, No Middlemen
We roll and finish angles in our own mill in Tianjin, so the price we quote is the factory price, and the people you talk to are the people who control production. There is no trading house adding a layer of cost or uncertainty between you and the material. Every inquiry is answered by our in-house export team, every order is scheduled on our own rolling program, and every shipment is loaded under our supervision at Tianjin Xingang Port.
2. Full International Standards Compliance
Our angle steel is manufactured and tested to ASTM A36, EN 10056, GB/T 706, and JIS G3192, with steel grades Q235, Q345, SS400, and S235JR. Chemical composition, mechanical properties, leg dimensions, thickness, and squareness are verified against the applicable standard before release. Each shipment includes mill test certificates in EN 10204 3.1 format, and third-party inspection by SGS, BV, or TÜV can be arranged when your contract requires independent verification.
3. Stable Quality with Multi-Step Inspection
Quality control starts with billet analysis and runs through hot rolling, cooling, straightening, cutting, and surface inspection. We gauge leg width, leg thickness, and included angle with calibrated instruments at regular intervals, and our laboratory confirms yield strength, tensile strength, and elongation for every production lot. This multi-step inspection keeps our customer-arrival rejection rate below 0.5 percent, and every order is covered by our written quality guarantee.
4. Flexible Supply for All Project Scales
From a 5-ton stock order for a small fabricator to a 3,000-ton program for a transmission line or warehouse project, we scale to your demand. Popular sizes are stocked for rapid dispatch, while non-standard sections and special steel grades are rolled to order. We support mixed-container shipments, so angles can travel together with flat bars, square bars, channels, and pipes to reduce your freight cost per ton.
Steel Angle Product Range
Our angle steel range covers equal and unequal sections in carbon steel, galvanized finish, and stainless grades. Send us your drawing or size list, and we will confirm the most economical section, grade, and length for your project.
Equal Angle Steel
Equal angle steel has two legs of identical width, making it the most common section for bracing, framing, and support structures. It is rolled from 20×20×3 mm to 200×200×24 mm in grades Q235, Q345, SS400, and S235JR, with standard lengths of 6 m and 12 m. Equal angles are simple to detail, easy to weld or bolt, and available in black, painted, or galvanized finish, which is why they appear in everything from roof trusses and towers to racks and machine frames.
Unequal Angle Steel
Unequal angle steel has legs of different widths, such as 75×50 mm, 100×63 mm, and 125×80 mm, providing extra bearing area on the longer leg where loads are applied eccentrically. It is widely used in shipbuilding, steel structures, bridges, and vehicle frames where the section orientation must match the load path. We roll unequal angles in the same standard and grade range as our equal angles, with full dimensional verification of both legs and the included angle.
Galvanized and Stainless Steel Angle
Galvanized angle steel is hot-dip zinc coated, typically 40–85 g/m² or per your specification, for long service life in outdoor, coastal, and high-humidity environments such as solar frames, fencing, and transmission structures. Stainless steel angle in grades 304 and 316 provides corrosion resistance for food processing, chemical plants, marine fittings, and architectural projects, with pickled, bright, or polished surfaces. Both options are available across the common angle size range, with cut ends dressed and protected for shipping.

Typical Applications of Steel Angle
Steel angle is a true multi-purpose structural section. Typical applications include:
- Roof trusses, purlins, and bracing in industrial buildings and warehouses
- Transmission towers, communication masts, and solar mounting frames
- Bridge girders, gantries, and steel walkways
- Racks, shelving, and storage systems in logistics facilities
- Shipbuilding and offshore platform components
- Frames for machinery, vehicles, and agricultural equipment
- Fencing, gates, handrails, and architectural detailing
- Reinforcing and anchoring elements in concrete and masonry construction
Angle Steel Strength You Can Build On
The structural value of an angle section depends on precise geometry: leg widths, thickness, and a true 90-degree included angle that lets connections meet cleanly. Our rolling stands hold these dimensions consistently along the full length, straightening lines remove twist and bow, and shears produce square ends that butt up properly at joints. We verify section geometry on every bar and check the surface for rolled-in scale, cracks, and edge defects before packing. Because the material is consistent, your detailers can rely on standard section properties, your welders get clean joints, and your galvanizer or painter gets a surface that takes treatment evenly. This is the kind of reliability that keeps structural contractors returning to the same angle steel supplier project after project.

Buyer’s Guide: How to Choose a Reliable Steel Angle Supplier
When sourcing angle steel, start by defining the governing standard and grade for your project, then check that the supplier’s mill certificates actually match the delivered heat numbers. Verify leg dimensions and thickness against the standard tolerance table, because undersized sections can compromise structural calculations. For galvanized angles, agree on the zinc coating weight and request a coating test report if the application is corrosive. Compare the total landed cost, including freight, insurance, and duties, rather than the FOB price alone. Confirm packing and marking so bundles are identifiable on site, and test a new supplier with a small order before committing project-critical volumes. A factory supplier like Sino East Steel Group that publishes its capacity, standards, and inspection routine is far easier to trust than a trader that cannot show you its production line.

Frequently Asked Questions (FAQ)
Q1: What is the difference between equal and unequal angle steel?
Equal angle steel has two legs of the same width, such as 50×50×5 mm, and is the standard choice for bracing, framing, and general structural work where loads are roughly symmetrical. Unequal angle steel has legs of different widths, such as 75×50 mm, and is used where the load path is eccentric or where the longer leg provides extra bearing or connection area, for example in shipbuilding, bridge details, and vehicle frames. Your structural designer selects the section that best matches the load direction.
Q2: How is the theoretical weight of an angle calculated?
The theoretical weight is calculated from the section dimensions and a steel density of 7.85 g/cm³, using the formula in the applicable standard, which accounts for the two legs minus the corner overlap. For example, an L50×50×5 mm angle weighs approximately 3.77 kg/m. In practice, actual weights follow the standard weight tables for each section, and shipment invoicing is based on weighbridge weight at loading, which may differ slightly from theoretical values.
Q3: What zinc coating do you apply to galvanized angle steel?
Standard hot-dip galvanizing for angle steel is typically 40–85 g/m², and we can supply heavier coatings up to 400 g/m² for aggressive coastal or industrial environments. The coating weight, adhesion, and uniformity are verified per ASTM A123 or the equivalent standard you specify. If your project requires a coating test report or third-party verification of the zinc layer, we can arrange it before shipment.
Q4: Which stainless steel grade is best for angle steel in marine environments?
For coastal and offshore applications we recommend grade 316, which contains molybdenum for superior resistance to chlorides and seawater. Grade 304 is suitable for most inland industrial and architectural uses, including food processing and chemical plants. If your project involves constant saltwater exposure, we can also discuss duplex stainless angles with higher strength and better pitting resistance.
Q5: Do you supply angles for transmission towers and solar mounting structures?
Yes. Transmission tower legs, cross arms, and solar frame members are among our most common angle applications. We supply hot-rolled equal and unequal angles in Q345, SS400, and S235JR grades with verified mechanical properties, tight dimensional control for hole alignment, and documentation that supports your structural certification. Tell us the section schedule and we will confirm rolling and delivery timing.
Q6: Can you supply angles with pre-drilled holes or cut-to-size pieces?
Yes. For orders of 20 tons or more we can cut angles to your specified lengths and drill or punch bolt holes according to your shop drawings. Pre-cutting and hole punching reduce site labor and improve accuracy for repetitive framing and racking applications. Send us your cutting and drilling list and we will quote the processing cost together with the material price.
