Providing steel work services to London, Hertfordshire, Essex, Berkshire, Kent, Surrey and Sussex
HDM is a family run business offering a specialised service to our clients which sets us apart from many other steel fabrication companies. Sometimes it can seem very difficult to take an idea or design and actually get it fabricated, due to the complexity or the perceived cost of making a unique bespoke item. This need not be the case as HDM have the unique ability to take an idea and make it happen and in most cases it can be just as cost effective as trying to adapt a modular item.

Concept Art

Usually in order to see a 3D representation of a finished fabricated item you would normally need to approach a Visualisation company who will charge huge amounts to create a rendered image of your design, HDM offer this service at a fraction of the cost, which proves to be a vital tool in making sure the client knows exactly what to expect

2D and 3D CAD Drawings

Sometimes a simple structural steel requirement needs little in the way of additional CAD drawings than the ones provided to us from a structural engineer for example. However in some cases when there are compound angles or complicated connection details there is a necessity to generate detailed fabrication drawings in order to be able to even consider taking the job on. Having this in-house capacity means that we can overcome obstacles in design and prove a concept before a single steel has even been cut

Fabrication and Engineering

HDM have over 6000 square feet of workshop and factory with heavy machinery that you just would not find in most steel fabrication companies. This is due to having a engineer capacity and a working tool room on-site. Meaning that should a required component simply not exist we are able to use our milling machines, power presses and laithes to make almost any bespoke metal item.

Having a fully trained and experienced installation team who have worked in all varieties of enviroments gives us the ability to work around the constraints of a public building or the tight health and safety policies of a large site
