NEW Assisted Build

Our NEW and exclusive Assisted Build has been created to assist customers with manpower available that require direct skills on site. A service that offers as much or as little as you need – when you need it. Our service starts with the pre-assembly of the prime frame with all stanchions, mullions and rafters fully built with all relevant base cleats, haunch brackets and apex brackets fully bolted and ready to stand.

We then offer key stage assistance direct to site. Our fully skilled and experienced site supervisors will meet you on site on key stages throughout the build to offer expert help, advice and training to your team. We charge the consultancy service on a day rate and provide recommended key dates depending on the size and complexity of the building.

Our Assisted Build service ensures that you keep your costs to a minimum whilst being reassured having an expert direct on site to assist the build. You supply the labour and heavy lifting; we supply the skills and expertise. It’s that simple. Plus, we still offer the same expert remote support throughout the build via telephone, Facetime, Skype and email to ensure everything runs to plan.

Local Groundworks

As groundworks are typically labour intensive, it can often be beneficial to appoint local contractors for this stage of the build and leave us to construct and assemble your Premium Steel Garage. Many customers already have an existing base and only require footings. Every Premium Steel Garage comes with full slab and footings plans with clear instructions and dimensions for you or your contractor to follow.

 For customers local to our stores in Bishop’s Stortford – Hertfordshire (within 25 miles), who would rather have every stage of the build taken care of by Steel Build Masters, we will be happy to offer a price for all your groundworks and arrange a full site survey to discuss your project in person.
