A Comprehensive Introduction to A36 Steel Plate

A36 steel plate is one of the most commonly used carbon structural steel plates in the global market, conforming to ASTM A36 standards. Its moderate strength, good weldability, easy fabrication, and cost-effectiveness make it widely applicable across a variety of industries including construction, machinery, bridges, shipbuilding, automotive, and steel structure engineering.

1. Material Characteristics

As a low-carbon steel, A36 contains less than 0.26% carbon, which gives it excellent ductility and tensile strength. It offers a minimum yield strength of 250 MPa and tensile strength between 400–550 MPa. These properties ensure its suitability for most structural applications. Moreover, it supports secondary processing such as welding, cutting, punching, and forming at room temperature.

2. Key Advantages

Excellent Weldability: Compatible with MIG, TIG, and arc welding without the need for pre-heating or post-treatment.
Good Formability & Cutability: Suitable for laser cutting, CNC punching, and hot-rolled forming.
Flexible Customization: We provide A36 plates in thicknesses from 4mm to 100mm, widths from 1000mm to 3000mm, and lengths up to 12000mm.
Cost-effective: Compared to high-strength steels, A36 offers a better price-performance ratio, ideal for volume purchasing and general projects.

3. Wide Application Fields

Construction: Structural beams, columns, brackets, baseplates, and exterior frameworks.
Bridge Engineering: Load-bearing panels, connecting parts, and key structural components.
Machinery Manufacturing: Frames, bases, machine shells, and mounting components.
Energy & Equipment Foundations: Applied in power stations, oil rigs, and heavy-duty support frames.
Transportation & Infrastructure: Used in guardrails, decking plates, and container flooring.

4. Quality Assurance & Services

We strictly follow ISO quality management standards. All A36 plates comply with ASTM, EN, or JIS standards and third-party test reports (SGS, BV, TUV) are available upon request. Every plate undergoes ultrasonic flaw detection, flatness inspection, and mechanical property testing before shipment.

We offer value-added services including surface coating, hole drilling, bending, and bevel cutting. With sufficient stock and fast delivery capacity, we ensure smooth supply for global clients.
