RHS Steel Sheds

More Steel. More Strength. Built for Bigger Demands.

The MRN R-Series is our RHS structural steel shed system, designed for projects that require a more substantial steel frame while still maintaining an efficient and versatile building solution.

Typically suited to spans of up to 18.0 metres, the R-Series is ideal for residential sheds, agricultural buildings and small commercial projects where additional structural capacity, durability or a more substantial frame is desired.

RHS — rectangular hollow section — steel provides a rigid, robust frame that is well suited to sheds where strength and long-term performance are priorities.

Why choose the R-Series?

Built stronger for bigger demands, with the versatility to suit almost any project.

100% Aussie

Made in Australia. For Australia.

Every MRN shed is built using Australian-made steel, giving you confidence in the materials behind your building.

We use only quality COLORBOND® and ZINCALUME® steel cladding, available in a range of profiles and colours to suit your project.

Built by experienced local trades


The R-Series is designed, supplied and constructed by MRN Sheds with the support of experienced local trades.

From the initial design and approvals through to the slab, steelwork, cladding and final handover, MRN can manage the entire project from start to finish.

For customers wanting a stronger, more substantial structural solution without moving into a large commercial steel building, the MRN R-Series provides the ideal balance of strength, flexibility and value.

T. Doddridge

MRN Rigging and construction recently designed and built my new dream shed in East Albury. Jordan and the MRN team shared their experience and knowledge and ideas to help me come up with the ideal shed and features to suit my business. The shed is my workshop and perfect storage solution and suits my block and surrounds perfectly. Jordan and Mitch have the best trades people on their team and their chosen subcontractors were all excellent, skilled, punctual and great workers.
I can highly recommend MRN, they made the whole process of design and building and construction streamlined and stress free. I have also worked in one of their large shed constructions and these guys are amazing at what they do and can do.
From a workshop shed like mine to a huge industrial complex MRN have the proven skills and knowledge to build what they promise. A great shed!
Thank you Jordan, Mitch and the MRN team! you guys rock!

After looking at some photos from MRN my shed is a baby at 18×9×3.2, but what a fantastic job Mitch and the team did. Communication was foremost from the office and Mitch gave updates along the way.
Very professional, precise work and my shed will be there for a long time. 6 months later and the power has finally been connected and the boys dropped in after a hard days work to calibrate the roller doors as part of the service. Highly recommend MRN for your shed adventure.

common questions

Common questions about our construction work

Need more information? Get in touch with us.

It means MRN’s structural steel workers, riggers, carpenters, plumbers, and boilermakers are on the MRN payroll not sourced from labour hire when needed. They show up consistently, they’re accountable to MRN, and they know our standards. For complex or specialist work beyond our core team, we engage trusted external trades and hold them to the same standard.

We operate to a high OHS standard on every site site-specific safety plans, Safe Work Method Statements for all high-risk work, induction requirements for all personnel, and ongoing safety oversight throughout the construction period. Subcontractors are held to the same standard as our own team.

Yes MRN quotes every element of a construction project in full: building permits, development approvals, structural engineering, civil works, supply, and installation. If you’ve received a cheaper quote elsewhere, we’re happy to compare line by line and show you what’s included and what isn’t.

Yes MRN’s fabrication capability and suppliers means we can produce custom structural steel components as well as install them. This is particularly relevant for projects with non-standard connection details, crane provisions, or bespoke structural requirements.

Residential, commercial, industrial, and agricultural construction, structural steel buildings, warehouses, factories, and large-scale shed builds. MRN also delivers full project management (turnkey) for larger builds where the client needs one team to handle the complete scope from permits to handover.
