Hangan Steel is a top provider of commercial steel subfloors in Melbourne. We design and build high-strength foundation systems for the Victorian business building sector. Commercial projects usually need to hold much more weight than standard homes. They also need to be built much faster to keep up with tight business schedules. As a leading steel fabrication company in Melbourne, we provide strong, engineered floor solutions for offices, shops, and modular spaces.
Our steel subfloor systems in Melbourne give you a steady, level, and long-lasting base for any large business use. Our team of structural steel contractors in Melbourne works with engineers and site managers. We make sure our frames fit perfectly with the rest of your building. This results in a foundation that is both smart and very strong.
Building alterations require a “measure twice, cut once” philosophy. Our team is skilled at working within the constraints of existing shells to deliver high-precision steelwork.
Modernizing a building often requires removing load-bearing walls to create open-plan spaces or new entry points. We install “strong-back” systems and lintel beams to support the load while the original structure is modified. Our building alterations in Victoria ensure that the transition from old to new is structurally seamless and safe.
In many retrofit projects, we add new mezzanine levels or cut voids into existing floors for feature staircases and elevators. This requires complex structural steel modifications, including the reinforcement of existing columns to handle new vertical loads. Our onsite welding crews are experts at creating these connections in tight, restricted-access environments.
Adding heavy HVAC units or modern glass facades to an older building usually requires reinforcing the roof or perimeter steel. We provide retrofit bracing and custom-fabricated supports that allow older structures to carry the weight of modern technology and materials.
Retrofitting is more complex than new construction. It requires a contractor who can adapt to the “as-built” realities of an existing site.
We use advanced laser scanning and manual verification to ensure our new steel fits perfectly within the existing (and often imperfect) structure.
Safety is critical when altering a standing building. We coordinate with engineers to provide temporary propping and shoring, ensuring the building remains stable during every phase of the modification.
Retrofit work often takes place in active urban areas or occupied buildings. We manage our onsite welding in Melbourne and cutting operations to minimize noise and vibration impact on neighbors and tenants.
We ensure that all retrofitted sections bring the building up to current AS/NZS structural standards, providing full certification for all new steelwork and connections.
Yes. We are experts at working in live environments. We use specialized hoarding, fire-watch protocols, and fume extraction to ensure our structural steel modifications can proceed safely without disrupting the occupants.
We use a variety of specialized chemical anchors, mechanical fixings, and custom-welded brackets. Every connection is engineered to ensure load is transferred safely between the different materials.
Yes. Because retrofit projects often deviate slightly from the original plans due to site conditions, we provide updated documentation that reflects exactly what was installed for your future records.
