3mm custom galvanized steel plate: durability and precision

At John Steel, we offer a 3mm thick galvanized steel plate, cut with unmatched precision and fully customizable to your dimensions. Galvanized steel is known for its excellent corrosion resistance, thanks to its protective zinc layer, making it a preferred choice for a multitude of indoor and outdoor applications.

Why choose 3mm galvanized steel?

  • Optimal corrosion protection: Galvanization effectively protects steel against rust, significantly extending the lifespan of your creations.
  • Versatility of use: Ideal for supports, reinforcements, body parts, agricultural equipment, or outdoor decorative elements requiring good protection.
  • Lightness and maneuverability: With 3mm thickness, this plate offers a good compromise between robustness and ease of implementation.
  • Custom cutting: Benefit from a plate perfectly adapted to your requirements, without waste or loss.

Common applications

Our 3mm galvanized steel plate is perfect for creating machine parts, roofing elements, containment trays, wall protections, outdoor signage, or for manufacturing urban furniture and light structures exposed to the elements. Its surface can be painted or left as is for a functional industrial look.

Your custom cut in a few clicks

Easily configure your 3mm galvanized steel plate by entering the desired dimensions. We ensure high-precision laser or plasma cutting for a flawless result, delivered quickly to your home.

    Le concept est vraiment bien et pratique. La livraison a été faite dans le délai, même en avance. Par contre la finition est à améliorer, car il y a pas mal de rayure et micro-rayure gênante.
