Our Structural Steel Angles range covers equal and unequal angles for structural connections, bracing, frames and support components. We supply hot-rolled and hot-dip galvanized options in Q235B, Q355B and SS400, with standard lengths as well as cut-to-length service. Common sizes can be supplied from stock, while special materials, dimensions and lengths can be arranged according to the order requirements.
Both legs have the same nominal width, giving the section a symmetrical L-shaped profile. It is commonly used where the connection or supporting arrangement calls for balanced leg dimensions.
The two legs have different widths. This provides more flexibility when one side of the section needs to extend farther for connection, support or framing purposes.
The perpendicular legs provide a practical geometry for connecting, reinforcing and supporting steel components in frames, trusses and bracing assemblies.
| Item | Specification | Material |
|---|---|---|
| Equal Angle | 20 × 20 × 3 mm – 200 × 200 × 24 mm | Q235B, Q355B, SS400 |
| Unequal Angle | 25 × 16 × 3 mm – 200 × 125 × 18 mm | Q235B, Q355B, SS400 |
| Standard Length | 6 m / 9 m / 12 m | — |
| Cut Length | 3–12 m | According to order requirements |

For angle sections used in fabricated structures, dimensional consistency is important because the two legs form the connection geometry. We pay attention to the section angle, thickness uniformity, straightness and surface condition so the material can be processed through common fabrication operations such as drilling, shearing, cutting and welding.
| Detail | Why It Matters |
|---|---|
| Section angle | Helps maintain the intended geometry when the material is assembled with other structural members. |
| Thickness | Needs to match the specified section and fabrication requirements. |
| Straightness | Supports easier positioning, cutting and assembly. |
| Surface condition | Relevant to handling, fabrication and subsequent surface treatment. |
Black Structural Steel Angles can be used where the section will receive painting or another finishing process. For outdoor structures or applications where corrosion protection is required, hot-dip galvanized material provides a zinc-coated surface after galvanizing treatment.
The choice between the two is normally related to the installation environment and the project's surface-treatment requirements rather than the section shape itself.
Standard 6 m, 9 m and 12 m lengths are available, while cut lengths from 3 to 12 m can be arranged for projects with specific dimensional requirements. Cutting before shipment can reduce part of the preparation work required after the material reaches the fabrication site.
For orders involving drilling, shearing or other processing requirements, the required dimensions and processing details should be confirmed before production so the supply can be matched with the intended assembly method.
| Application | Typical Role |
|---|---|
| Curtain Wall Frames | Connection and supporting components within steel framing structures. |
| PV Mounting Structures | Triangular bracing and support members. |
| Warehouse Racking | Structural and connecting components for storage systems. |
| Communication Towers | Truss and bracing members. |
| Fences and Guardrails | Frames, supports and connecting sections. |
| Steel Buildings | Bracing, tie members and secondary structural components. |
| Cable Tray Supports | Support frames and brackets for cable management systems. |
| Advertising Sign Frames | Supporting and reinforcing members for steel sign structures. |
Common sizes are maintained through regular stock supply, subject to actual inventory at the time of order. For projects requiring several dimensions, mixed-size orders can be arranged so different specifications are supplied within the same project order.
When the required material, section size or length is outside the regular range, we can also discuss special production requirements before confirming the order.
For overseas orders, long steel sections need suitable bundling and protection during handling and sea transportation. We arrange export packing according to the product dimensions and shipment requirements, with attention to rust and moisture protection during long-distance transportation.
Yes. Different specifications can be arranged within the same project order, subject to quantity and production or stock conditions.
Yes. Our Structural Steel Angles range includes equal angles from 20 × 20 × 3 mm to 200 × 200 × 24 mm and unequal angles from 25 × 16 × 3 mm to 200 × 125 × 18 mm.
Yes. Both black and hot-dip galvanized surface options are available. The appropriate surface should be selected according to the installation environment and corrosion-protection requirements.
Yes. In addition to 6 m, 9 m and 12 m standard lengths, cut lengths from 3 to 12 m can be arranged according to the order requirements.
Special material, dimensions and cutting requirements can be discussed before production. The final supply arrangement depends on the specified section and order quantity.
