Why Designers Specify Stonini

• Hand-cast texture: every panel is individually cast by hand, so each piece carries natural variation that machine-pressed or injection-moulded panels can’t replicate.
• Fire compliance without workarounds: Group 1 and non-combustible certification remove the location restrictions that rule out many decorative linings in commercial, healthcare and multi-residential projects.
• Weight: at approximately 14 kg/m², Stonini lightweight wall panels give the look of concrete, stone or rammed earth without the structural load of the real material.
• Colour control: panels are made from a tinted composite and can be matched to any Dulux, Resene or Taubmans colour.
• Interior and exterior: one product family for feature walls, ceilings and facades.

Custom Design Process

If a standard profile doesn’t suit your concept, we can develop a custom panel with you. Here’s how a custom project runs:

1. Consultation: we review your concept drawings or sketches and discuss the design intent.
2. Design refinement: we adjust the design for manufacturability and flag any limits set by the material or casting process.
3. Prototype: we cast a prototype for you and your client to review.
4. Approval and production planning: once the prototype is approved, we agree production deadlines and delivery schedules, including staged delivery to match your installation program if needed.
5. Manufacture: production starts once all details are confirmed.

Ordering Standard Panels

1. Confirm the profile and specification, including colour and panel size.
2. Confirm quantities for the project.
3. Arrange packaging and delivery to suit your site and program.

Samples and Showroom Visits

Samples are the best way to judge texture, colour and finish before you specify. Contact us to request samples for client presentations or material boards, or to book a showroom visit. You can also see completed installations in our project gallery.

Working With an Australian Manufacturer

All Stonini panels are designed, hand-cast and finished at our factory in St Marys, Sydney, NSW. For Australian projects, that means:

• Shorter lead times and easier coordination of delivery schedules and late changes.
• Direct contact with the manufacturer for custom work, specification questions and after-sales support.
• Exact colour and texture matching for your project.
• Shorter transport distances than imported panels.
