Certified Quality Assurance

At Progressive Metal Manufacturing, we ensure every delivery meets rigorous industrial standards.

All EN8 materials are available with BS EN 10204 3.1 mill certificates or cast and analysis reports to guarantee chemical and mechanical integrity. Our technical sales team is ready to assist you in securing the necessary documentation and specifications for your project's success.

Industrial Applications & Versatility

We maintain a comprehensive inventory of EN8 to support diverse manufacturing workflows.

Whether you require standard lengths or custom-processed blanks,

our facility is equipped to provide precision sawn-to-length services.

For high-accuracy applications, we also supply precision ground bars finished to exceptionally tight tolerances.

Round Bars: Diameters available from 10mm to 650mm.

Steel Sheets/Plates: Thicknesses from 10mm up to 350mm.

Square & Flat Sections: Squares up to 200mm and flats ranging from 30mm to 255mm.

Hexagonal Profiles: Specialized hex bars available for fastener production.

Precision Supply & Custom Specifications

EN8 is the "go-to" specification for general engineering projects that demand higher mechanical properties than mild steel.

Its reliability makes it the preferred choice for:

Transmission Components: High-performance shafts, spindles, and rollers.

Fastening Solutions: Heavy-duty bolts, studs, and specialized screws.

Mechanical Assemblies: Connecting rods and various stressed engine or machine parts.
