Materials and Finishes Used in Our Commercial Projects

When delivering commercial projects, the materials and finishes are critical in ensuring durability, aesthetics, and overall performance. At Greenline, we carefully select high-quality materials suited to each project's unique demands. Here’s a deep dive into the materials and finishes Greenline employs across our commercial structures.

Fabrics We Use

Fabric membrane structures are known for their architectural flexibility and visual appeal. Greenline uses tensile membrane structure materials, each chosen for strength, UV resistance, light transmission rates, and adaptability.

Each of these tensile membrane fabrics offers versatility and long-lasting performance. We use them to ensure our tensile structures provide both functionality and an aesthetic edge. HDPE, PVC, and PTFE have colour options to help you customise your structure.

PVC

We use this cost-effective fabric widely in tensile membrane structures. It offers UV protection, is waterproof, has excellent durability, and is highly resistant to weather conditions.

LEARN MORE

HDPE

Our team uses HDPE (or shade cloth) in shade structures because it has superior strength and UV resistance. It provides excellent UV protection, and its mesh structure allows airflow through the membrane.

LEARN MORE

PTFE

PTFE is a highly durable membrane material used in long-span tensile structures. Its non-stick properties make it an excellent choice for projects that demand long-term performance and minimal maintenance.

LEARN MORE

ETFE

Tensioned membrane designers use ETFE widely as a lightweight alternative to glass. Its transparency allows natural light to flow through while blocking UV radiation. This makes it ideal for projects where natural light is key.

STFE

This flexible roofing membrane is ideal for projects requiring flexibility and a clean, modern aesthetic. A lightweight yet strong material, STFE can span great widths with less support than other materials. It allows for high levels of light transmittance while maintaining excellent durability and UV resistance.

Engineers sign off on all Greenline’s fabric and steel roof structure designs to ensure they withstand the elements. Each structure is custom-designed to offer clean lines and a modern look. All the steel in our structures is Australian-made. We provide a variety of surface finishes and colour options so you can tailor your structure to meet your needs.

Hot-dipped galvanised steel is the basis of all our structural steel finishes. Its corrosion-resistant properties make it ideal for projects exposed to harsh weather.

When newly manufactured, steel is a bright, shiny silver colour. The zinc coating sometimes gives it a mottled appearance.

Unlike stainless steel, exposure to the environment causes the steel to undergo a natural weathering process over time. This exposure leads to a protective zinc patina forming, which gives the steel a uniform matte grey appearance. This transformation typically occurs within six months to two years.

Our team will help you determine whether the galvanised steel for your project needs to be powder-coated. Aesthetics and/or environmental conditions drive the decision more often than not. The key driver will decide whether the steel requires a two-coat or three-coat powder-coat system.

Powder coating enhances the appearance of the steel and provides extra protection against rust and environmental damage.

Two-coat powder-coat system: Common for most projects, this finish includes a primer and top-coat that offers solid protection.

Three-coat powder-coat system: We apply an additional coat for harsher environments to ensure maximum longevity and resistance to wear.

Our steel roof structure materials are designed to withstand the Australian climate. We use metal roof systems that are not only strong but visually striking. These roofs feature high-quality metal finishes, ensuring they last for years without significant maintenance.

Our steel roof and wall cladding come in a variety of profile and colour options. This allows our design team to meet the specific needs of each project.

Timber

While most Greenline projects use steel to provide structure, timber is becoming an increasingly popular option. Timber in tensile membrane structures can add warmth and character to the space. The design team at Greenline can incorporate timber into specific designs, creating a natural contrast to steel.

Skylights and Infills in Steel Roof Structures

Skylights and infills are essential features in many of Greenline’s steel roof designs. By integrating skylights into steel roof cladding, we allow natural light to enter the space. This reduces the need for artificial lighting and improves the building's energy efficiency. Installing skylights in steel roof structures offers a balance of light and weather protection.

Infills in shade structures are also a weather protection feature. They allow our team to design your structure to maximise protection from the sun and weather.

Greenline's Commitment to Quality

At Greenline, we are committed to using the best materials and finishes in our commercial projects. We have been independently ISO 9001:2008-Quality Management certified since 2009. We carefully select every material to ensure durability, functionality, and aesthetics.

We select these materials and finishes to ensure our projects offer form and function. Our team custom-designs every Greenline project and assists you in selecting appropriate finishes. We ensure that our projects meet the highest standards, providing long-term value to our clients.

Greenline—helping you build smarter, better commercial spaces with the right materials.
