MAH Steel provides structural steel fabrication for residential, commercial and industrial projects across London, Kent and the South East. We work with homeowners, builders, contractors and engineers who need steel supplied at a competitive price without compromising the preparation and service behind it.
The work starts with your drawings and specification. Using modern saw and drill lines, we achieve precise cuts and boreholes for consistent fit-up on site, helping reduce delays and installation issues. All steel is fabricated to your specifications and prepared for efficient installation.
Drawings and 3D models can be provided where required, allowing for clear planning, approval, and coordination before fabrication begins. We can also help coordinate CAD drawings, steel erection and HIAB delivery where those services form part of your project.
RSJs, UBs, UCs and channels
Frames, trusses and bespoke steel
Plates and connection details
Delivery ready for installation
Structural steelwork. Made for the project.
MAH works with everything from individual load-bearing members to fabricated assemblies. The engineer's drawings and agreed specification determine the final sizes, grades and connections.
Beams, columns and sections
RSJs, universal beams (UBs), universal columns (UCs), channels, angles and flats cut and prepared to your project schedule. Individual members can be drilled, plated and fabricated to suit the intended connection and installation method.
Used for extensions, loft conversions and commercial structures
Structural frames and assemblies
Goalpost frames, structural frames and trusses, beams with supporting columns and bespoke assemblies for alterations, extensions and larger structures. Fabrication follows the approved frame layout and connection information.
Used for goalposts, trusses and bespoke frameworks
Plates, stiffeners and connections
End plates, cleats, stiffeners and welded or drilled connection details. The aim is clear fit-up and installation against the approved project information, with the correct drawing details agreed before fabrication.
Used for plating, welded details and drilling
Bespoke and on-site steelwork
Project-specific steel components, site adjustments, welded connections and remedial work. When the programme or existing steelwork creates a problem, MAH can discuss what can be fabricated or rectified and how access will affect the job.
Used for site fabrication, remedial work and custom packages
More about structural steel fabrication.
What builders, contractors, designers and homeowners need to know before they order.
01Steelwork made to your drawings
Fabrication starts with the required steel schedule, structural engineer's information and agreed details. Individual beams may need cutting and drilling, while larger packages involve plates, connection points, welded members and coordinated assemblies. MAH can discuss where CAD services, 3D modelling or a site survey will help clarify the work before production.
02From individual beams to full packages
MAH supplies and fabricates RSJs, universal beams, universal columns, channels, angles, flats and bespoke steelwork. Common projects include loft conversions, residential extensions, basement works, commercial shopfronts and wider structural alterations. For frames, trusses or complex connections (see steel connection design), the technical drawings and specification determine exactly what is made and how the steel is to be assembled.
03When site conditions change
Not every steelwork problem can be solved in the workshop. MAH also undertakes on-site fabrication and welding, including individual connections, modifications and remedial work where the existing steelwork or site conditions need attention. Working on an active site can involve extra time, cost, access and safety considerations, so talk to the office early about the scope, drawings, access and timetable.
04Workshop preparation
Processing and fabrication should reflect the drawings that the project team has agreed. Cutting, hole positions, plates, welded details and delivery handling are all part of making the steel usable on site. The scope of any inspection and finishing is agreed for the particular project.
05Cost, programme and urgent requirements
Price matters in steel fabrication, and MAH recognises that. A useful quotation also accounts for preparation, connections, the agreed finish, delivery, site access and the programme. Clear drawings, quantities, site information and an indication of when the steel is needed help MAH provide a clear, competitive quote. If you need steel urgently, please call our office on 01322 276948 and tell us what you need and when. We cannot promise an urgent fabrication or delivery date, but we will do everything we reasonably can to help.
06Transport, lifting and installation
A fabricated steel package still has to reach the right place at the right time. MAH's own fleet and HIAB capability allow the team to discuss planned unloading, narrow access, lifting arrangements and how the delivery fits the construction programme. Where required, speak to MAH about steel delivery, HIAB lorry-crane delivery and steel erection as part of the same enquiry.
Five fabrication disciplines. All part of the job.
These are core MAH capabilities, with their own specialist pages for customers who want the machinery, processes and specification in greater detail.
On-site steel fabricationOn-site fabrication and welding, from single welded connections to remedial steelwork where the existing steelwork or site conditions need attention.→
Steel welding and fabricationMIG, TIG, gas and structural steel welding for fabrication, repairs and architectural metalwork such as railings and gates.→
CNC steel profilingCNC steel profiling and laser cutting of plates and sections, with drilling, milling, scribing and marking for fabrication-ready steel.→
Steel beam drillingSteel beam drilling for bolted connections, plate and cleat holes and onsite adjustments, using magnetic base drills for accurate hole placement.→
Steel plate punchingSteel plate punching for holes and slots in flats and angles, as part of a wider cutting and fabrication package.→
The fabrication journey brings drawings, machinery, experienced people and delivery planning together. These are connected stages, not separate orders, and the precise stages depend on the individual steel package, drawings and services agreed with MAH.

Structural steel fabrication questions and answers.
Straightforward answers about the structural steelwork MAH fabricates, how drawings and details are agreed, and how steel reaches site. More answers are in our FAQs.
What structural steelwork can MAH fabricate?
MAH supplies and fabricates structural steel for residential and commercial projects, including beams, columns, frames, connections and bespoke components. The exact sections and fabrication details depend on the approved project specification.
Can you provide steel beams for home extensions?
Yes, this is one of our core services. We supply everything from a single RSJ for internal wall removal to complex goalpost frames for bifold door installations.
Can you make steelwork to suit an unusual project?
Yes. Bespoke fabrication is available where the required components, connections or dimensions go beyond straightforward supply of standard sections. MAH will review the drawings and technical requirements before confirming the proposed work.
Do you supply welded and drilled components?
MAH provides fabrication and processing services that include cutting, drilling and welding as required by the approved drawings. Hole locations, connection details and weld requirements must be specified and agreed before manufacture.
Do you deliver steel directly to site?
Yes, we operate our own fleet of vehicles equipped with HIAB cranes, allowing us to deliver and position steel precisely where it is needed, even in restricted locations.
