When you’re choosing steel coils for your project, strength, performance, and cost are the deciding factors. At Midwest Steel Supply, we stock a full range of steel coils to meet the needs of industries from construction and transportation to manufacturing and energy. Two of our most requested products are ASTM A572 Grade 50 High-Strength Structural Steel Coils and ASTM A283 Mild Carbon Steel Coils.

This guide explores both products in depth — from their properties and applications to ASTM A283 steel coil price per ton — helping you choose the right material for your next project.

1. Understanding ASTM Standards for Steel Coils

ASTM International sets globally recognized standards for steel grades. When you choose ASTM-certified steel, you know it meets strict mechanical, chemical, and dimensional requirements.

• ASTM A572 Grade 50: A high-strength, low-alloy (HSLA) structural steel known for exceptional weldability and corrosion resistance.

• ASTM A283: A mild carbon steel used for general-purpose fabrication and structural applications where strength requirements are moderate and cost is a priority.

2. ASTM A572 Grade 50 Steel Coil – Strength Meets Efficiency

ASTM A572 Grade 50 is designed for high-stress structural work where weight reduction without loss of strength is essential. The higher yield strength (minimum 50,000 psi) allows engineers to use thinner sections, lowering overall weight and cost in large projects.

Key Features

• Yield Strength: ≥ 50,000 psi

• Tensile Strength: 65,000–80,000 psi

• Good Atmospheric Corrosion Resistance (especially compared to standard carbon steel)

• Excellent Weldability & Machinability

• Good Formability for bending and shaping

Applications

• Bridge girders and structural beams

• High-rise building frameworks

• Heavy machinery components

• Offshore platforms

• Transmission towers and wind turbine structures

Using A572 Grade 50 means fewer materials are needed to achieve the same structural capacity, lowering transportation and fabrication costs.

3. ASTM A283 Steel Coil – Affordable, Reliable, and Easy to Work With

ASTM A283 is a low to intermediate tensile strength carbon steel that is easy to form, weld, and machine. While it doesn’t have the same high strength as A572, it offers excellent value for general-purpose fabrication.

Key Features

• Yield Strength: 27,500 – 38,000 psi (depending on grade A–D)

• Tensile Strength: 38,000 – 60,000 psi

• Excellent Formability for bending, rolling, and shaping

• Smooth Surface Finish suitable for painting or galvanizing

• Cost-Effective for large-scale fabrication

Applications

• Storage tanks and pressure vessels

• Light structural frames and supports

• Boilers and heat exchangers

• Agricultural equipment

• Industrial containers and piping

4. Price per Ton – ASTM A283 Steel Coil

The ASTM A283 steel coil price per ton varies based on:

• Thickness & Width: Thicker coils require more material and cost more per ton.

• Surface Treatment: Galvanizing or painting adds cost.

• Order Volume: Bulk orders reduce unit price.

• Market Trends: Steel market index fluctuations influence pricing daily.

Current Market Range (FOB mill pricing, subject to change):

• ASTM A283: $550 – $750 per ton

• ASTM A572 Grade 50: $750 – $950 per ton

For precise pricing, Midwest Steel Supply provides real-time quotes based on specifications and delivery location.

8. Choosing the Right Steel for Your Project

When deciding between A572 Grade 50 and A283, consider:

• Structural Load Requirements: For high-load applications like bridges, A572 Grade 50 is the clear choice.

• Budget Constraints: For cost-sensitive projects, A283 provides a balance of strength and affordability.

• Corrosion Environment: If exposed to weather, A572 Grade 50 offers better atmospheric corrosion resistance.
