Equal Angles: Sizes, Weight Chart, Prices & Specifications

Equal Angles: Sizes, Weight Chart, Prices & Specifications<\/h2>

Equal angle steel (also called equal leg angle, angle bar, or L-section) is the most widely specified hot-rolled structural section in the world. The two legs of an equal angle are identical in length and meet at a right angle, which makes it the natural choice for bracing, framing, brackets, and connections in steel buildings. This page is the complete buying reference from Sino East Steel Group — a direct steel structure manufacturer in Tianjin, China: equal angle steel sizes and the full steel angle weight chart, material grades and galvanizing options, 2026 export prices, and the exact way to order equal angles for your project.

1. What Is an Equal Angle?

An equal angle is a hot-rolled steel section with an L-shaped cross-section in which both legs have the same width. It is produced by reheating a steel billet, rolling it through a series of passes that form the leg and root geometry, and then straightening, cooling, and cutting the bar to length. Because the two legs are identical, an equal angle behaves symmetrically under load and can be bolted or welded in either orientation without re-detailing, which simplifies fabrication and reduces errors on site.

Equal angles are manufactured to international dimensional standards including EN 10056-1/2 (European equal and unequal angles), GB/T 706 (Chinese hot-rolled sections), ASTM A36 / A572 (American structural angles), and JIS G 3192 (Japanese dimensions). The steel itself is supplied to EN 10025-2, ASTM A36, ASTM A572, JIS G 3101, or GB/T 1591 depending on the grade required for your market and design code.

2. Equal Angle vs Unequal Angle: Which One Do You Need?

Comparison	Equal Angle	Unequal Angle
Cross-section	Both legs the same length (e.g. 100 × 100)	Two legs of different lengths (e.g. 100 × 63)
Typical sizes	20 × 20 × 3 up to 200 × 200 × 24	30 × 20 × 3 up to 200 × 150 × 18
Load behaviour	Symmetric about the leg bisector; uniform stiffness both ways	Asymmetric; higher stiffness along the long leg
Best for	Bracing, connections, brackets, purlin struts, general framing	Primary/secondary beams, stair stringers, roof edges, frames with unequal moments
Stock availability	Very high — most mills roll equal sections continuously	Good but less standard; some sizes are made to order
Cost	Slightly lower per tonne on standard sizes	Small premium on less common combinations

Most steel structures use equal angles for bracing and connection details, while unequal angles appear where a beam or edge member must carry more load in one direction. See our unequal angles page for the full size and weight data of the alternative profile.

Example: an order of 500 m of 100 × 100 × 10 equal angle weighs about 500 × 14.92 = 7,460 kg, so a 20 ft container holding 20–22 tonnes covers roughly 1,400–1,500 m of that section. Tell us the total tonnage and we will calculate the exact container loading plan.

5. Material Grades & Corrosion Protection

Grade / Option	Specification	Best For
Structural carbon steel	Q235B / S235JR — yield 235 MPa	General framing, bracing, connections
High-strength steel	Q355B / S355JR / ASTM A572 Gr.50 — yield 355 MPa (345–355)	Heavy loads, long members, seismic areas
American grades	ASTM A36 — yield 250 MPa	Projects specified to US codes

For complete projects — angles plus primary steel and purlins — see our procurement guide for importers.

10. Tolerances, Standards & Marking

Equal angles are supplied to the dimensional tolerances of EN 10056-2 and GB/T 706: leg tolerance typically ±1.0 mm on sections up to 100 mm and ±1.5 mm above, thickness tolerance ±0.3–0.5 mm depending on size, and a maximum leg deviation of 2° at the corner radius. Length tolerance is +0/+40 mm for random lengths and +0/+5 mm for exact cut lengths. Each angle carries mill-rolled or stencilled marks showing the size, grade, heat number, and manufacturer, and bundles include a tie-on tag with your project details.

Chemical composition and mechanical properties are tested per the ordered grade: for Q235B/S235JR, yield ≥ 235 MPa and tensile 370–500 MPa; for Q355B/S355JR, yield ≥ 355 MPa and tensile 470–630 MPa. If your engineer needs Charpy impact values, specify the sub-grade (e.g. S355J2) so the mill tests at −20 °C.

11. Packing, Shipping & Delivery

Equal angles are bundled in 2–5 tonne packs, strapped with steel bands, and stowed in 20 ft or 40 ft containers or break-bulk holds at Tianjin Port. Long sections up to 12 m are loaded on flat-rack containers or in open-top configurations; we confirm the most economical loading method for your length mix. Standard export documentation — commercial invoice, packing list, bill of lading, certificate of origin, and EN 10204 3.1 mill test certificates — is provided with every shipment.

Typical transit times: 3–4 weeks to the Middle East (Jebel Ali), 4–6 weeks to East and West Africa (Mombasa, Lagos), 4–5 weeks to Europe, and 3–5 weeks to North America. For full-project shipping details, read our international shipping and installation guide.

12. Equal Angle FAQ

Q: What are the standard equal angle steel sizes?
A: Standard sizes run from 20 × 20 × 3 mm to 200 × 200 × 24 mm, with intermediate series such as 25 × 25, 40 × 40, 50 × 50, 63 × 63, 75 × 75, 100 × 100, 125 × 125, and 150 × 150 in multiple thicknesses. Standard lengths are 6 m and 12 m.

Q: How much does equal angle steel cost in 2026?
A: In 2026, Q235B/S235JR equal angles run roughly USD 520–620 per tonne FOB China, Q355B/S355JR USD 560–680 per tonne, and hot-dip galvanized angles USD 780–950 per tonne. Freight and duty vary by destination.

Q: How do I read the steel angle weight chart?
A: The chart gives theoretical kg per metre for each size and thickness. For example, a 50 × 50 × 5 equal angle weighs about 3.73 kg/m and a 100 × 100 × 10 about 14.92 kg/m. Multiply by total length to get tonnage, then add 3–5% for section weight deviation.

Q: What is the formula for equal angle weight?
A: Theoretical weight = (2 × leg width − thickness) × thickness × 0.00785 kg/m. This is the GB/T 706 method and matches the table above within ±3–5% of actual mill weights.

Q: Which standard are equal angles made to?
A: Dimensions follow EN 10056-1/2, GB/T 706, ASTM A6/A36, or JIS G 3192; steel grades follow EN 10025-2, GB/T 1591, ASTM A36/A572, or JIS G 3101. We produce to the standard you specify.

Q: What is the difference between equal and unequal angles?
A: An equal angle has two legs of the same length (100 × 100); an unequal angle has different legs (100 × 63). Equal angles are used for symmetric bracing and connections; unequal angles for members with higher stiffness in one direction. See our unequal angles page.

Q: Can equal angles be galvanized?
A: Yes — we supply hot-dip galvanized equal angles to ISO 1461 with typical coating thickness 70–85 µm, ideal for coastal, humid, and outdoor structures such as towers and outdoor platforms.

Q: Do you cut, drill, or fabricate equal angles?
A: Yes. Our fabrication shop cuts angles to exact length, drills or punches bolt holes, and welds brackets, gussets, and frames to your shop drawings, saving you site labour.

Q: How do I get an equal angle quotation?
A: Email your size, length, quantity, and destination port to paul@sinoeaststeel.com or message us on WhatsApp — you will receive an itemized FOB/CIF quotation within 48 hours.
