Order fabricated RHS steel sections in Melbourne from approved drawings showing size, grade, connections, finish and installation interfaces.
Fabricated RHS steel sections can suit residential modifications when an engineer has specified the hollow section, connections and load path for the actual building. Heidelberg Lintels supplies rectangular and square hollow sections and fabricates structural steel for Greater Melbourne projects. We work from engineering and architectural information; RHS is not a universal substitute for a beam, lintel or column.
Our structural steel supply and fabrication services cover hollow sections, universal beams and columns, channels, lintels, shop drawings and installation support. The project documentation determines which section belongs in the modification.
Where RHS Can Fit a Residential Modification
RHS may be nominated for posts, frames, supports or other members where a closed rectangular profile suits the engineer’s design. Wall removals, extensions and new openings can involve several connected steel elements, so one member cannot be priced or fabricated accurately without its plates, holes, welds and adjoining interfaces.
Our published article on universal beams for home renovations explains a related section type. It does not make UB and RHS interchangeable; the structural engineer must nominate the member required.
What Must the Drawings Show Before Fabrication?
A useful quotation package should provide current, coordinated information rather than a sketch with missing connection details:
- Section specification: Confirm RHS dimensions, wall thickness, steel grade, orientation and member mark.
- Connections: Show end plates, cleats, caps, stiffeners, holes, welds and fixing requirements.
- Critical dimensions: Identify levels, spans, set-outs and interfaces with existing walls or steelwork.
- Surface treatment: Nominate prime painting, galvanising or another finish where specified.
- Delivery and erection: Provide site access, lifting constraints, sequence and installation responsibility.
Our guidance on steel shop drawings and structural clashes shows why missing dimensions and unresolved interfaces should be corrected before fabrication rather than transferred to the installer.
Keep Design and Fabrication Responsibilities Clear
Shop drawings translate the approved design into fabrication information; they do not replace structural engineering. Site measurements may be required where new steel meets an existing building, but measured conditions still need to be reconciled with the engineer’s requirements and the builder’s construction sequence.
Standards Australia’s overview of revised structural steel standards identifies AS/NZS 1163 for cold-formed structural steel hollow sections and AS/NZS 5131 for fabrication and erection. The project team must specify the editions, execution requirements and documentation applicable to the job.
Heidelberg Lintels can provide supply, fabrication and, where agreed, steel erection and onsite fixing. The final scope depends on drawings, access and quotation review.
Revision control is especially important during renovations because site discoveries can change the steel package. Builders should issue revised drawings formally, identify superseded documents and confirm whether fabrication has started. Verbal changes create avoidable risk when several members or connection details are involved.
