3mm Corten Steel Sheet Price

A 3mm Corten steel sheet is a commonly used weathering steel plate in architectural cladding, landscape structures, and outdoor construction. The price of a 3mm Corten steel sheet is usually calculated based on material weight, sheet dimensions, and processing requirements.

Because Corten steel is typically sold by weight, understanding the price calculation formula helps buyers estimate project costs more accurately.

Basic Price Calculation Formula

The price of a Corten steel sheet is usually calculated using the following formula:

Weight of steel sheet:

$$\text{Weight (kg)}=\text{Length (m)}\times \text{Width (m)}\times \text{Thickness (mm)}\times 7.85$$

Total sheet price:

$$\text{Sheet Price}=\text{Weight (kg)}\times \text{Price per kg}$$

In this formula:

• 7.85 represents the density of steel in kg/dm³

• Length and width are measured in meters

• Thickness is measured in millimeters

Example Price Calculation for 3mm Corten Steel Sheet

For a standard 3mm Corten steel sheet with dimensions 1219 × 2438 mm (4 × 8 ft):

Step 1: Convert dimensions to meters

• Length: 2.438 m

• Width: 1.219 m

• Thickness: 3 mm

Step 2: Calculate weight

Weight = 2.438 × 1.219 × 3 × 7.85

Weight ≈ 70 kg per sheet

Step 3: Calculate price

If the material price is calculated per kilogram:

Sheet Price = 70 kg × price per kg

This formula is commonly used in steel trading to estimate sheet material cost.

Common Sizes of 3mm Corten Steel Sheets

3mm Corten steel sheets are supplied in several standard sizes used in fabrication and construction.

Larger sheet sizes increase the total weight and therefore affect the final material price.

Factors That Affect the Price of 3mm Corten Steel Sheet

Several factors influence the total cost of weathering steel sheets:

Material grade – Different weathering steel standards may vary in alloy composition.
Sheet size – Larger plates increase weight and total cost.
Surface condition – Pre-rusted or specially treated surfaces may require additional processing.
Cutting and fabrication – Laser cutting, bending, or pattern cutting adds processing costs.
Order quantity – Large volume orders may reduce per-unit costs.

Typical Applications for 3mm Corten Steel Sheet

3mm thickness is widely used because it provides a balance between strength, flexibility, and workability.

Common uses include:

• Architectural wall cladding

• Landscape garden edging

• Decorative outdoor panels

• Metal screens and partitions

• Raised garden beds and planters

This thickness is easy to cut, bend, and weld, making it suitable for architectural and landscape fabrication projects.
