End-to-end structural steel fabrication for your industry

Whether you work within the automotive, engineering, manufacturing, food and beverage, transport and logistics, leisure or construction industry, we can help create steel structures to maximise your efficiency and how you use your space.

What can be made through structural steel fabrication?

Structural steel fabrication can be used to create a wide variety of structures and components, including:

This versatility makes structural steel fabrication a fundamental process in modern construction and engineering.

Structural steel benefits

High Strength-to-Weight Ratio: Structural steel is strong yet lightweight, enhancing building strength without adding excessive weight.

Durability and Longevity: Resistant to decay, weather, and pests, ensuring long-term structural integrity.

Design Flexibility: Allows for creative and complex architectural designs due to its malleability.

Speed of Construction: Prefabrication enables faster assembly, reducing construction time and costs.

Sustainability: Steel is recyclable and often contains recycled content, making it a more environmentally friendly construction material.

Our structural steel fabricators can support you with these services

We offer a variety of structural steel fabrication services, including:

Our welding teams are experts in the four main types of welding:

  • Metal Inert Gas (MIG) welding
  • Metal Active Gas (MAG)
  • Tungsten Inert Gas (TIG)
  • Gas welding and brazing

Whether you need products welded for industrial or commercial use, our team has the capability to exactly match your requirements for your bespoke sheet metal fabrication project.

Bending and Forming
These techniques manipulate the shape of the workpiece. In the hands of a skilled metalworker a hammer or a tap and die set becomes a remarkable bending tool. For mechanised bending and sheet metal folding, we have powered hammers as well as a press brake for heavy-duty and precision work.

Our sheet metal fabrication department is capable of bending or forming any sheet metal between 1mm and 4m in length. Our team at Customised Sheet Metal can advise on the most appropriate forming technique for your needs. We can work with metal to exacting tolerances, meaning that we are in a great position to take on any bespoke metal fabrication project no matter how complex.

Our finishing department applies the finishing and decorative processes when they are required. This might be for aesthetic appearance or for safety. What we can guarantee is that before any metal products leave our factory they are well assembled, safe and up to specification.

What are the different grades of structural steel?
The different grades of structural steel, classified based on their chemical composition and mechanical properties, include:

  • EN 10025: 2004: This standard provides specifications for the delivery conditions, properties, quality, dimensions, and definitions of structural steel products.
  •  Eurocode 3: Part of the Eurocode series of European standards related to construction, specifically addresses the design of steel structures, including general rules, structural fire design, supplementary rules for cold-formed members and sheeting, and plated structural elements.

These grades are selected based on the specific requirements and demands of the construction project.

What is a chord in steel parts fabrication?
A chord in steel structure fabrication refers to the main longitudinal member of a truss, which interacts with the web members to support loads, often seen as the top and bottom segments in truss structures, providing overall stability and load distribution.

What is the cost per ton of structural steel?
The cost of structural steel in the UK is around £1,300 per ton​​. Contact us for current pricing information.
