Rusting Steel (Cor-Ten) Laser Cut Screens

Cor-Ten steel is unlike any other material we work with — and for the right project, there is simply nothing else like it.

Also known as weathering steel, Cor-Ten is a high-strength steel alloy engineered to form a stable, tightly-bonded layer of rust on its surface when exposed to the elements. Rather than continuing to corrode as ordinary steel would, this patina layer acts as a protective barrier, sealing the steel beneath and halting further deterioration. The result is a material that is genuinely low maintenance, exceptionally durable, and grows more visually compelling with age.

The warm, earthy tones of the rusting patina — ranging from deep amber and burnt orange through to rich chocolate brown — make Cor-Ten a favourite among architects, landscape designers and homeowners who want a material with genuine character and a strong connection to the natural environment. No two Cor-Ten installations age in exactly the same way, meaning your screens, gates or panels develop a finish that is entirely their own over time.

It is important to note that during the initial weathering period, Cor-Ten will produce rust run-off. This should be considered at the design and installation stage, particularly where the material is positioned above light-coloured paving, renders or cladding. Once the patina has fully stabilised, run-off ceases.

Cor-Ten is an excellent choice for garden screens, feature panels, gates, facade cladding, landscape architecture and any application where a bold, organic aesthetic is desired. It is available in its natural weathering finish and can also be sealed or coated if a fixed colour is preferred.

We use only Australian made 3mm HW350 weathering steel for all our rusting laser cut screens.

Available sheets sizes:

1200mm x 2400mm

1200mm x 3000mm

Gauges:

3mm and 6mm only

What is weathering steel?

Weathering steel, best-known under the trademark COR-TEN steel is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance if exposed to the weather.

Does it come pre-rusted?

Weathering steel arrives UNRUSTED and will rust with natural exposure to the weather.

Weathering steel requires alternating wet and dry cycles to form a properly adhered protective layer. Areas that have salt laden air, high rainfall, humidity, or persistent fog are typically not the proper environment for weathering steel.

Will weathering steel continue to rust?

Weathering Steel never completely stops rusting. The weathering process occurs after the panel is installed. It eventually decreases and from that point on the finish acts as a protective coating for the base metal.

This protective coating essentially stops the corrosion. Laboratory analysis of the rust film have shown that the alloying elements in the steel, particularly copper, chromium, and nickel produced insoluble compounds that clogged the pores at the rust/steel interface, thereby ending the regeneration.

Will the rust stain the surrounding areas?

Yes, rust runoff will likely stain the surrounding areas. It is not recommended to use weathering steel on any light coloured painted, wood or tiled surfaces.

Is there a warranty?

There are no warranties for weathering steel.

Can you use dissimilar metals and weathering steel?

In general do NOT use dissimilar metals with weathering steel.
Galvanized, galvalume®®, and zinc should NOT come into contact with weathering steel. Stainless steel is compatible with weathering steel.

What fasteners should I use?

It is recommended to use only 316 stainless steel screws.
