Elevate your fabrication projects with our 4mm mild steel sheet, offering enhanced thickness and durability for various applications. Perfect for construction, engineering, and manufacturing needs, this steel sheet guarantees optimal weldability and formability.

Customise your order with precise cut-to-size dimensions and additional specifications, including drilled holes, rounded corners and cutouts.

Please note:

  • Our mild steel products come with a mill finish, meaning they are in their raw, unfinished state with a rough, matte surface. There may be rust and they are likely to have sharp, rough edges when cut.
  • If you are adding drilled holes to your order, they will not be suitable as precision engineering parts.

4mm Mild Steel Sheet Applications

  • Roll beam trollies
  • Door Skins: For cladding wooden or hollow core doors, 4mm steel sheets provide durability, fire resistance, and soundproofing. 
  • Base Plates: Machinery often uses 4mm plate steel as sturdy base plates for mounting components.
  • Brackets: 4mm has enough strength for various bracket configurations to mount shelves, signs, panels and hardware.
  • Garden Edging: A straight 4mm sheet makes for neat garden bed edges and dividers in pathways.
  • Heat Shields: 4mm works for modest heat shielding needs like exhaust wraps or engine covers.
  • Panels: For covering cabinets, machines, walls and enclosures, a 4mm sheet is easily fabricated into detachable panels.
  • Trays: Custom trays, bins and organizers for tools, hardware, or supplies can be cut from 4mm. 
  • Lockers: School or workplace lockers can be constructed from a 4mm sheet for the sides, doors, and partitions.

When selecting the thickness of your sheet, please consider your project's load-bearing requirements.

Cannot fault the product itself, the cut corners option is very cool. Am uncertain if I ordered out of stock as the two week wait time for a UK delivered product was bad. Tried to purchase another plate and every single piece no mater what grade or thickness was out of stock. Went elsewhere!
