A covered riding arena changes how you use your property year-round. Rain, wind, and UV exposure no longer dictate your riding schedule, and your footing stays consistent regardless of the season.

Trusteel Fabrications designs and builds horse arena roof covers using Rectangular Hollow Section (RHS) structural steel, universal beams (UB), or Open Web Trusses (OWT), with the frame type selected according to the clear span and load requirements of each arena. Every arena roof cover Trusteel builds is custom-designed to the arena size, the site conditions, and the riding discipline it needs to serve. To understand how these frame types compare, see Trusteel’s guide to RHS, UB, and C-section framed sheds.

What a Horse Arena Roof Cover Actually Does

Riding without a roof means weather determines your schedule. Rain softens footing, UV exposure dries it out, and wind carries dust and debris into the arena. A covered arena removes those variables.

A well-built steel cover also protects the investment you have made in your arena surface. Consistent moisture levels in the footing reduce maintenance costs and keep conditions predictable for your horses.

Structural Steel Versus Lighter Frame Options

Trusteel builds arena roof covers using RHS structural steel, universal beams (UB), or Open Web Trusses (OWT), not C-section frames. C-section is lighter and cheaper. It suits light-duty storage structures where spans are modest and dynamic loads are low.

At the widths required for a functional riding arena, typically 20 metres or more, C-section frames carry real risk under wind load and deflection over time. RHS, UB, and OWT frames hold their shape across those spans because their section geometry resists lateral and vertical forces more effectively than a cold-formed profile. 

Which of the three suits a specific arena depends on the span, the roof load, and whether the structure needs to clear an unusually wide opening without intermediate support.

Standard Arena Sizes and What They Mean for Your Structure

Equestrian Australia guidelines recognise two standard arena sizes. A standard dressage arena is 20 x 40 metres. A full-size competition arena is 20 x 60 metres. A lunging circle requires a minimum 20-metre diameter clearance.

Each of these dimensions sets a minimum clearspan width. Your roof structure must cover that full width without internal columns interrupting the riding space. Trusteel designs to these standard sizes or to custom dimensions where your site requires a different footprint.

Roof-Only or Enclosed: Choosing the Right Configuration

The two primary configurations are a roof-only cover with open sides, and a partially or fully enclosed arena building. Each suits different conditions and budgets.

Open-sided covers maximise airflow through the arena, reduce condensation on roof sheeting, and cost less to build. They are suitable for most Victorian conditions and remain the more common choice for equestrian facility owners.

Partially or fully enclosed structures offer better weather protection and allow year-round riding in more exposed locations. Full enclosure changes the building classification under the National Construction Code and generally increases both permit complexity and construction cost.

Permits and Council Approval in Victoria

A permanent roofed arena structure of this scale will generally require a building permit under the Building Act 1993. Planning approval may also apply depending on your zone, Bushfire Attack Level (BAL) rating, and any council overlay on your property.

Equestrian structures are not automatically exempt from these obligations. The Victorian Building Authority (VBA) registration Trusteel holds means permit management is part of the project. You do not engage a separate registered builder or manage council correspondence on your own.

Most Victorian councils process rural building permits, but requirements vary. Trusteel’s VBA registration means permit management is part of the project. You do not engage a separate registered builder or manage council correspondence on your own. 

How Trusteel Builds Horse Arena Roof Covers

Site Evaluation and Design

Trusteel begins with a site evaluation to confirm dimensions, ground conditions, and any council or planning constraints. The design is then drawn to your arena size, whether that follows standard equestrian sizing or a custom footprint.

Fabrication and Construction

All steel fabrication is completed in-house at Trusteel’s Mulgrave facility. Trusteel’s own crew handles installation across Victoria. There is no kit supply arrangement and no third-party builder to coordinate.

If you want to know what a horse arena roof cover would cost for your property, and what permits your council requires, contact the Trusteel team.

Frequently Asked Questions

Do I need a building permit for a horse arena roof cover in Victoria?

A permanent roofed arena structure will generally require a building permit under the Building Act 1993. Planning approval may also apply depending on your zone and council overlay. Requirements vary between councils, so Trusteel confirms the specific obligations for your site during the design phase. Trusteel’s VBA registration means the permit process is managed as part of your project.

What is the standard size for a covered riding arena, and can Trusteel build to custom dimensions?

A standard dressage arena is 20 x 40 metres and a full-size arena is 20 x 60 metres, as recognised by Equestrian Australia. These are the most common sizes Trusteel designs to, but custom dimensions are available where your site requires a different footprint. Trusteel’s in-house design team works to your specific measurements. There is no standard kit that your site must conform to.

What is the difference between a roof-only arena cover and a fully enclosed arena structure?

A roof-only cover has open sides, which maximises airflow and reduces construction cost. A fully enclosed arena provides greater weather protection but changes the building classification under the National Construction Code, which generally increases permit complexity and cost. Partially enclosed configurations are also available. The right choice depends on your climate exposure, budget, and intended use.

Why does Trusteel use RHS steel frames rather than C-section framing for arena covers?

RHS, UB, and Open Web Truss frames resist lateral and vertical loads better than C-section at the wide spans an arena requires, typically 20 metres or more of clearspan. Trusteel selects between the three based on the specific span and load needs of each arena, all of which hold their shape over the life of the structure.

How long does the design and construction process take from first contact to completion?

Timeframes vary depending on the complexity of the design, permit requirements, and site conditions. The design and permit phase is typically the longest stage, particularly where planning approval is required. Fabrication is completed in-house, which removes delays associated with third-party suppliers. Trusteel confirms a project timeline during the quotation stage once site and permit details are established.
