Manufacturing Mild Steel for Construction and Defence

Universal supports its customers through welding, machining and assembling mild steel fabrications.

Our customers benefit from fabrications with the following key characteristics:

Cost-Effectiveness: Generally less expensive than other steels, making it suitable for large-scale projects without compromising quality
Ease of Fabrication: Easy to weld, form, and machine, supporting efficient production in construction frames and defence
Durability and Low Maintenance: Offers long-term resistance to corrosion and wear, making it cost-effective for military and law enforcement fleets
Durability and Strength: Offers good tensile strength and resistance to fatigue, ideal for building frames, chassis, and non-critical defence components
Versatility and Corrosion Resistance (When Treated): Galvanised mild steel resists corrosion, extending lifespan in harsh environments

Our use of technology and recycling practices ensures we provide our customers with a sustainable manufacturing solution.

Mild Steel Welding Specialists Serving Watford

Fabrication & Welding

Universal manufactures a wide range of structures, from plant equipment frames to military vehicle chassis. Our welding processes include MIG, TIG, CMT, and robotic welding. Using our experience, we are able to support you with the most appropriate welding solution for your project. All welders are qualified to BS EN ISO 9606-1, with BS EN 3834-2 accreditation for safety-critical applications.

We regularly work with industry-standard mild and structural steels including:

S275 JR / J0 / J2 – General construction-grade steels with a minimum yield strength of 275 N/mm².
S355 JR / J0 / J2 / NL / NL+ – Higher strength structural grades with a minimum yield strength of 355 N/mm².
EN3B / EN8 – Mild steel bar grades for machined components.
CR4 – Cold-reduced mild steel for formed or pressed parts.
High-yield and HSLA grades – For lighter-weight, high-strength applications.
500HB and RHA – Used where additional hardness or ballistic protection is required.

We also handle customer-specified grades for specialised needs.

Robotic Welding – Repeatable, Quality Fabrication

For batch production, we utilise robotic welding for consistent results and reduced times, ideal for repeatable sub-frames or modular chassis. Overseen by experienced engineers, it ensures efficiency and quality.

Precision CNC Machining – Milling & Turning for Mild Steel in the UK

Our in-house CNC capabilities support small precision components to large structures. Milling on 3, 4 & 5 axis machines handles up to 2m x 2m for post-weld accuracy. Turning up to 500mm in diameter, with crane handling up to 10 tonnes for heavy-duty work.

Chassis & Sub-Assembly Build

We manage complete chassis and sub-assemblies, integrating fabrication and machining for reliable fits, especially for hydraulic or drivetrain components.

Leak Testing & Surface Finishing for Mild Steel Projects

We provide leak and pressure testing for sealed units. Surface services include blasting, priming, powder coating, and painting for industrial and specialist uses.

Quality Control & Documentation

ISO 9001:2015 systems ensure traceability, supplying PPAPs, FAIRs, weld procedures, and reports. On-site inspectors and CMM equipment guarantee quality.

Prototype Your Design. Scale Your Production

From one-off prototypes to full runs, Universal Fabrications supports your mild steel manufacturing in the UK with confidence.
