We're very proud of our new Lawsons Steel facility, and we'd love to show you around personally.

If you are a business that uses structural steel and would like to know more about our services and capability, fill in your details below for an informal one-to-one appointment with our Steels Director at our Colney Heath base (just off junction 22 on the M25).

You'll get a guided tour of the Lawsons Steel design, fabrication and warehousing facilities along with a chance to see our innovative Loft Lifter delivery trucks (if they're not all out on deliveries!).

Just fill out the form and we'll be in touch to discuss a time.

Our steel is delivered on our industry-leading fleet of Loft Lifter trucks.

These innovative vehicles carry an extendable long-beam crane, with stabilisers that allow the crane to extend both horizontally and vertically.

Steel (and other materials) can be lifted directly from the truck to your scaffold, rooftop site or even direct to a loft space, without the need for an additional crane facility on-site.

The Steel Division is closely linked to our Lofts Division, offering a complete solution for the loft converter.

Our dedicated team of lofts specialists can project manage your loft conversion supplies, from selection of materials to final delivery on our Loft Lifter delivery vehicles.
