BOLTMONT

Steel structure erection and precast installation for logistics and industrial buildings.

We install steel frames and precast elements as a subcontractor – for general contractors building logistics centres and industrial halls, and for steel and precast manufacturers that sell without installation.

Who we work for

General contractors

Logistics centres, warehouses, production halls and other industrial buildings. We take on the steel frame or precast erection package and work to your site schedule, erection sequence and safety rules.

Steel and precast manufacturers

You sell the frame or the elements; we install them on your customer's site. That lets you offer supply and installation without an erection crew of your own.

Services

Steel structure erection

Columns, beams, trusses, bracing and secondary steel. Bolted connections tightened and recorded.

Precast element installation

Columns, beams, hollow-core slabs and wall elements, installed to your production and delivery plan.

Logistics and industrial buildings

Logistics centres, warehouses, production halls and tech-park buildings.

Supervision and documentation

Site supervision, bolt tightening records, tolerance surveys and handover documentation to the project specification.
