As a core product of TianJin ShengTeng Steel—a professional China-based manufacturer specializing in steel products—our Prime Quality Hot-Rolled MS Angel Steel Profile stands out for its exceptional performance and versatility. This product, also commonly referred to as "Angel Iron," is available in two main types: Equal Angle Steel and Unequal Angle Steel, catering to diverse industrial needs for structural support and framing.
Crafted through advanced hot-rolling technology, the MS (Mild Steel) base material ensures the angle bars possess uniform thickness, stable mechanical properties, and excellent weldability—key advantages that make them a preferred choice for both light and heavy-duty applications. Unlike low-quality alternatives, our angel steel undergoes strict quality control from raw material selection to final inspection, guaranteeing compliance with international standards and consistent performance in harsh environments (e.g., high humidity, mechanical stress).
TianJin ShengTeng Steel, with years of expertise in steel production, complements this product with a full range of supporting steel solutions, including steel pipes, galvanized pipes, and scaffolding products. This one-stop supply capability enables us to meet integrated project requirements, reducing procurement complexity for global clients.
Our Hot-Rolled MS Angel Steel Profile adheres to rigorous manufacturing standards, with specifications customizable to meet client-specific demands. Below is a detailed parameter table for common models:
Specification Item | Equal Angle Steel (Typical Range) | Unequal Angle Steel (Typical Range) | Unit |
Leg Length (A) | 20 - 200 | 25 - 200 | mm |
Leg Length (B) | Equal to A | 16 - 125 | mm |
Leg Thickness (t) | 3 - 24 | 3 - 24 | mm |
Length (L) | 6 - 12 (Customizable up to 18) | 6 - 12 (Customizable up to 18) | m |
Material Grade | Q235B, Q355B (ASTM A36 optional) | Q235B, Q355B (ASTM A36 optional) | - |
Yield Strength (σs) | ≥ 235 (Q235B), ≥ 355 (Q355B) | ≥ 235 (Q235B), ≥ 355 (Q355B) | MPa |
Tensile Strength (σb) | 375 - 500 (Q235B), 470 - 630 (Q355B) | 375 - 500 (Q235B), 470 - 630 (Q355B) | MPa |
Elongation (δ5) | ≥ 26% (Q235B), ≥ 22% (Q355B) | ≥ 26% (Q235B), ≥ 22% (Q355B) | % |
Surface Treatment | Black oxide, hot-dip galvanizing, painting | Black oxide, hot-dip galvanizing, painting | - |
Tolerance Standard | GB/T 9787 (China), EN 10056 (EU) | GB/T 9787 (China), EN 10056 (EU) | - |
The hot-rolled manufacturing process eliminates internal stress in the MS material, resulting in angle bars with uniform grain structure and minimal deformation under load. This stability ensures long-term structural integrity, even in applications with continuous mechanical stress (e.g., building frames, bridge supports).
Mild Steel (MS) as the base material offers low carbon content (≤ 0.25% for Q235B), making the angle bars easy to weld using common methods (MIG, TIG, arc welding) without cracking. Additionally, the smooth surface and consistent thickness allow for efficient machining (drilling, cutting, bending) to fit complex design requirements.
While the standard black oxide surface provides basic rust protection, our optional hot-dip galvanizing treatment creates a zinc coating (thickness ≥ 85μm) that enhances corrosion resistance, extending the product’s service life to 15-20 years in outdoor or high-humidity environments (e.g., marine facilities, outdoor scaffolding).
Compared to high-alloy steel alternatives, our Hot-Rolled MS Angel Steel balances performance and cost. The use of locally sourced high-quality MS raw materials reduces production costs, while the long service life and low maintenance needs lower total ownership costs for clients.
Our Prime Quality Hot-Rolled MS Angel Steel Profile is widely used across multiple industries, thanks to its versatility and reliable performance:
• Building Frames: Used as horizontal and vertical supports in steel-structured buildings (residential, commercial, industrial), providing strong load-bearing capacity.
• Bridge Components: Applied in bridge decks and side rails, withstanding dynamic loads from vehicles and environmental factors (wind, temperature changes).
• Scaffolding Systems: Serves as crossbars and uprights in temporary scaffolding, ensuring stability for construction workers and equipment.
• Machinery Frames: Forms the structural base of industrial machinery (conveyors, presses, lathes), absorbing vibration and maintaining precision.
• Equipment Supports: Used to fix and support heavy equipment (generators, pumps) in factories, preventing displacement during operation.
• Railway & Highway: Installed as guardrail posts and signal tower supports along railways and highways, resisting impact and weathering.
• Container Manufacturing: Integrated into the frame of shipping containers, enhancing structural strength to withstand stacking and long-distance transportation.
• Greenhouse Structures: Acts as the main frame of agricultural greenhouses, supporting glass or film coverings and withstanding snow loads.
• Solar Panel Racks: Used to build ground-mounted or rooftop solar panel racks, providing stable support for solar modules over 25+ years of service.
Equal Angle Steel has identical leg lengths (e.g., 50x50x5mm), making it suitable for symmetric load-bearing scenarios (e.g., building frames). Unequal Angle Steel has different leg lengths (e.g., 75x50x6mm), ideal for asymmetric structures (e.g., equipment supports where one side needs more reinforcement).
Yes. We offer three main surface treatments:
• Black oxide: Cost-effective, suitable for indoor dry environments (e.g., machinery frames).
• Hot-dip galvanizing: Recommended for outdoor or humid environments (e.g., bridge components, greenhouses).
• Painting: Customizable color options for aesthetic or additional corrosion protection needs (e.g., commercial building interiors).
Please specify your requirements when placing an order, and we will adjust the production process accordingly.
Our products meet international standards, including GB/T 9787 (China), EN 10056 (EU), and ASTM A36 (USA). Each batch is tested for yield strength, tensile strength, and elongation, with an MTC provided upon request to confirm compliance.
• For standard specifications (as listed in the parameter table), the lead time is 7-10 working days (for orders ≤ 50 tons).
• For customized specifications, the lead time is 12-15 working days (depending on the complexity of the requirements and order quantity).
• For large orders (> 100 tons), we can arrange partial shipments to meet your project timeline—please contact our sales team for a detailed schedule.
Yes. We offer free samples (up to 2 pieces per model) for quality testing. Clients only need to cover the shipping cost. Samples are typically shipped within 3 working days and can be tested for mechanical properties, surface finish, and dimensional accuracy.
