Where fabrication
meets the building site.

Steel erection is one of the most important stages of any construction project. At MAH Steel, we are Kent-based structural steel fabricators providing steel erection services across London, Hampshire, Sussex and the South East, delivering safe, accurate installation of structural steel on site.

Our team handles everything from single beam placements to full structural frameworks, working closely with your design and fabrication requirements to ensure everything fits and performs as expected.

Steel erection is where design becomes reality. If steel is not installed correctly, it can lead to delays, costly rework, and structural issues later in the build.

MAH also offers structural steel fabrication, HIAB and lorry crane steel delivery and steel delivery, so the same enquiry can cover making the steel, getting it to site and fitting it, where this is agreed as part of the order.

What our steel erection
service includes.

Every project is different, so we adapt our approach to suit your site, access, and build requirements.

Structural steel installation

Structural steel installation on residential and commercial sites, from house extensions and loft conversions to larger structural frames.

Suits beams, columns and frames

Lifting and positioning

Lifting and positioning of steel beams and frameworks. MAH delivers with HIAB lorry cranes, so the lift can be planned together with the delivery.

Suits beams, frames and roof steel

On-site assembly

On-site assembly of pre-fabricated steel components: positioning, aligning and securely fixing steelwork to form the structural framework of a building.

Suits pre-fabricated components and connections

Installation to suit the site

Installation tailored to site access and working conditions. Our team is used to working on sites with tight access, height restrictions, and challenging conditions, so we can adapt to suit your project.

What builders, contractors and homeowners ask before the steel is erected.

Residential and commercial projects

Yes, we provide steel erection services for both residential and commercial projects across Kent and surrounding areas. From house extensions and loft conversions to larger structural frames, we install steelwork accurately and in line with engineer specifications. See steel for residential extensions and steel beams for loft conversions.

Why accurate erection matters

We focus on accurate placement of steel, secure fixing and connections, and maintaining structural integrity. A well-executed steel erection ensures the rest of your build can progress smoothly.

Fabrication, delivery and erection together

MAH provides structural steel fabrication, steel delivery and steel erection, so the same steel package can be made, delivered and fitted where this is agreed as part of the order. Share your drawings and site details so the team can review which services are needed. A steel site survey can confirm measurements before manufacture.

Planning the lift and the order of work

Delivery and installation can be planned in phases. On the Sevenoaks project, a single beam of over 8 metres weighing around 1 tonne was delivered and installed first, and the remaining components followed in later phases. Our guide what your steel erector wants you to know covers site access, the crane and the order of work.

What to send for a quote

Send your engineer's drawings, the steel schedule or approximate quantities, the site location and any access, lifting, timing or site restrictions. Photographs and project plans help the team understand the job. If the details are not drawn yet, CAD services and steel connection design can help.

Health and safety

Health and safety are central to everything we do. That means safe working practices at all times, proper handling and lifting procedures, site-specific risk awareness and clear coordination with other trades. This approach helps protect both your site and your project.

Tell us about your site and the access when you enquire, so the team can plan around it.

Experience and site support

Our team brings experience across a wide range of projects, from residential extensions to larger commercial builds. We can advise on installation methods, identify and avoid potential site issues, work around access limitations and coordinate with your project manager or site team. You get practical input, not just steel installation.

From drawings to installed steel.

Erection is one stage in a longer sequence. Which stages apply depends on the steel, the drawings and the services agreed with MAH.

Review

Check the engineer's drawings, the steel details, the connections and the scope of the installation.

Plan

Consider delivery, access, lifting and the order of work with your project team.

Install

Lift and position the steelwork, then align and fix it to the agreed details.

Coordinate

Work with your project manager or site team so the next stage of the build can follow.
